The 15 biggest innovations

The new EQS1: the main points at a glance

The EQS is the first all-electric luxury sedan from Mercedes-EQ. With it, Mercedes-EQ is redefining this vehicle segment. The EQS is also the first model to be based on the modular architecture for luxury and executive-class electric vehicles. Fusing technology, design, functionality and connectivity, the EQS is designed to delight both drivers and passengers. The first models being introduced to the U.S. market will be the EQS 450+ with 329 hp and the EQS 580 4MATIC with 516 hp.

As part of its Ambition 2039 initiative, Mercedes-Benz is working on offering a carbon-neutral new car fleet within 20 years from now. As soon as 2030, the company wants more than half the cars it sells to feature electric drive systems - this includes fully electric vehicles and plug-in hybrids. In many areas, Mercedes is already thinking about tomorrow today: the new EQS is designed with sustainability in mind. The vehicles are produced in a carbon-neutral manner, with resource-saving materials such as carpets made from recycled yarn used. This is because Mercedes-Benz considers the entire value chain, from development and the supplier network to its own production. Furthermore, Mercedes-Benz AG had its climate protection targets confirmed by the Science Based Targets Initiative (SBTI).

With a great deal of meticulous detail work and on the basis of the Purpose design, the aerodynamicists, in close cooperation with the designers, were able to achieve a new cd  best value of 0.202. This makes the EQS the most aerodynamic production car in the world. The operating range particularly benefits from this. It is also among the best in terms of quiet running thanks to the decreased wind noise level.

The EQS currently sets a very good value for recuperation: Of the maximum deceleration in the DAuto recuperation program of 5 m/s², up to 3 m/s² is achieved by recuperation (2 m/s² by the wheel brakes). This allows decelerating to a standstill without using the brake pedal, while at the same time the range benefits from this recuperation strategy and the high recuperation power (up to 290 kW3). Deceleration is also applied to detected vehicles ahead until they come to a standstill, for example at traffic lights. Intelligent energy recovery is situation-optimized with the aid of ECO Assist and acts with foresight, taking into account traffic conditions or topography, among other things. The driver can also set three energy recovery levels and the coast function via paddle shifters on the steering wheel.

With ranges up to 770 kilometers (WLTP) and an output of up to 516 hp, the powertrain of the EQS meets every expectation of a progressive sedan in the S-Class segment. A performance version with up to 630 hp is being planned. All EQS models have an electric powertrain (eATS) at the rear axle, while the versions with 4MATIC also have an eATS at the front axle.

The EQS marks the launch of a new generation of batteries with significantly higher energy density. The larger of the two batteries has a usable energy content of 107.8 kWh. The innovative battery management software, developed in-house, allows updates over the air (OTA). This allows the energy management system to remain up-to-date throughout the life cycle. In terms of the cell chemistry, the cobalt content of the cathodes has been reduced to ten percent.

The EQS can be charged with up to 200 kW at fast charging stations with direct current. Power for up to another 300 kilometers (WLTP) is recharged in just 15 minutes1. At home or at public charging stations, the EQS can be conveniently charged with AC using the on-board charger. In addition, various intelligent charging programs can be activated automatically depending on the location, and functions such as battery-saving charging.

With Mercedes me Charge the driver can simply drive to the appropriate charging station2, open the flap, plug in and the current starts flowing: this is how easy the charging process is with the EQS, thanks to Plug & Charge. Other highlights include the densest network of charging points, with over 90% coverage of public charging points in the USA.

Navigation with Electric Intelligence plans the fastest and most convenient route, including charging stops, based on numerous factors and reacts dynamically to traffic jams or a change in driving style, for example. A new feature of the EQS is a visualization in the infotainment system (MBUX Mercedes-Benz User Experience) showing whether the available battery capacity is sufficient to return to the starting point without charging. Charging stations along the route that have been favorited are given preference in the route calculation while certain charging stations can be excluded, if selected by the driver. Additionally, the estimated charging costs per charging stop are calculated for the driver.

Although the EQS is a close relative of the new S-Class, it is built on an all-electric architecture. This completely new concept made a Purpose Design possible: with its one-bow lines and cab-forward design with fastback, the EQS is clearly distinguishable from vehicles with combustion engines, even at first glance. The design philosophy of Sensual Purity, combined with Progressive Luxury, is reflected in generously sculpted surfaces, reduced joints and seamless transitions (seamless design).

The front is combined into a 'Black Panel' unit. Innovative headlights connected by a light band and the deep black radiator grille (Black Panel) form the distinctive face. The exclusive look of the Black Panel radiator grille with central Mercedes star is enhanced still further: the grille also features a three-dimensional star pattern. This Mercedes-Benz Star pattern is available in conjunction with AMG Line Exterior or with the standard Mercedes-EQ body styling. The design picks up on the original star of the Daimler- Motorengesellschaft, which was registered as a trademark in 1911.

The EQS is the first Mercedes to offer the option of activating completely new vehicle functions via over-the- air updates (OTA) in many functional areas. Available from launch: two special driving programs, games and the demo program "The Best or Nothing". This means that, following the purchase and the initial new-car configuration, some of the features of the EQS can be adapted according to personal preferences. It will also be possible to unlock the rear axle steering with the larger steering angle of ten degrees. In addition to the classic purchase of individual functions, subscriptions, temporary activations and free test phases are also planned.

With ENERGIZING AIR CONTROL PLUS, Mercedes-Benz is taking a comprehensive approach to air quality in the EQS. The system is based on filtration, sensors, a display concept and air conditioning. The HEPA (High Efficiency Particulate Air) filter has a very high filtration level that enables it to trap fine particles, micro-particles, pollen and other substances that enter with the outside air. Sulphur dioxide, nitrogen oxides and odors are also reduced thanks to an activated charcoal coating. The HEPA filter has the "OFI CERT" ZG 250-1 certification in the area of viruses and bacteria. Using pre-entry climate control, it is also possible to clean the interior air before getting into the vehicle. The particulate levels outside and inside the vehicle are also displayed within MBUX. They can be viewed in detail in the dedicated Air Quality menu. If the quality of the outside air is low, the system can also recommend closing the side windows or the sliding sunroof.

As an option, the EQS has automatic comfort doors4 at the front and rear. When the driver approaches the car, the door handles extend, then as they approach further, the driver's door opens automatically.

Continuing the seamless entry experience, once the brake pedal is depressed the driver’s door can then close automatically. Using MBUX, the driver is also able to open the passenger and rear doors, for example, to let in children in front of school.

As an exceptionally intelligent vehicle, the EQS has up to 350 sensors, depending on the equipment. These record distances, speeds and accelerations, lighting conditions, precipitation and temperatures, seat occupancy as well as the driver's blink of an eye or the passengers' speech. This wealth of information is processed by control units that, controlled by algorithms, make decisions at lightning speed. Making them the brain, so to speak. The new EQS can expand its capabilities based on new experiences, because it is highly capable of learning thanks to artificial intelligence (AI).

The all-around sound experience in the EQS also makes the paradigm shift from a conventional to an electric car audible. A variety of soundscapes allows for an individual acoustic set-up. In combination with the standard Burmester® surround sound system, the EQS features the two soundscapes Silver Waves and Vivid Flux. Sound Experiences can be selected or switched off on the central display. An additional soundscape can be unlocked using over-the-air technology. The interactive driving sound, which is reproduced via the sound system's loudspeakers in the interior, also moves within the respective sound world.

New to ENERGIZING COMFORT are the three ENERGIZING NATURE programs Forest Glade, Sound of the Sea and Summer Rain. These provide an immersive and impressively realistic on-board sound experience. These calming sounds were created in consultation with the acoustic ecologist Gordon Hempton. As with the other programs that form part of ENERGIZING Comfort, lighting moods and images are used to address other senses.

The standard rear-axle steering with a steering angle of up to 4.5 degrees contributes to the agile and dynamic impression of the EQS. Alternatively, rear-axle steering with a steering angle of up to ten degrees can be ordered or subsequently activated via an over the air (OTA) upgrade. This enables a turning circle of 35.7 feet for the EQS, which is over 16 feet long. This is equivalent to the turning circle of many models in the compact class. The respective rear-axle angles and trajectories are shown in the driving mode menu in the central display.

Thanks to powerful sensors that monitor the vehicle's surroundings, the parking systems can help the driver with maneuvering in tight spaces.

The MBUX Hyperscreen is the absolute highlight in the interior. This large, curved screen unit sweeps almost from A-pillar to A-pillar. Three screens appear to merge into one as they sit under a single glass cover. The 12.3-inch OLED display for the front passenger gives them their own display and control area. The entertainment functions are only available while the car is being driven in accordance with the country- specific legal regulations. Mercedes-EQ relies on an intelligent, camera-based locking logic: if the camera detects that the driver is looking at the front passenger display, it is automatically dimmed to prevent driver distraction.

With adaptive software, MBUX adapts completely to its user and makes personalized suggestions for numerous infotainment, comfort and vehicle functions. With the zero layer, the most important applications are always offered on the top level within the field of vision, according to situation and context.

The latest generation of driver assistance systems includes numerous driver support functions. New, for example, is the additional microsleep warning from ATTENTION ASSIST. It analyzes the driver's eyelid movements through a camera on the driver's display (only available with MBUX Hyperscreen). The assistance display within the driver's display shows the operation of the driving assistance systems in a comprehensible full-screen view.

The principles of Integral Safety, in particular accident safety, apply regardless of the platform. Like all other Mercedes, the EQS therefore features a rigid passenger cell, special deformation zones and state-of-the-art restraint systems, with PRE-SAFE® including PRE-SAFE® Impulse Side equipped as standard. The fact that the EQS is based on an all-electric architecture also opened up new design possibilities for its safety concept. It meant, for example, that a favorable location could be chosen for the installation of the battery, in a crash-protected area in the underbody. And because there is no large engine block on board, the behavior in a frontal crash could be modeled even better. In addition to the standard crash tests, the car's performance in various additional load situations was verified and extensive component tests carried out at the Vehicle Safety Technology Center (TFS).

”The EQS is a milestone in Ambition 2039”

The Mercedes Management on the EQS1

”The EQS isdesigned to exceed the expectations of even our most discerning customers. That's exactly what a Mercedes has to do to earn the letter ’S’ in its name. Because we don't award that letter lightly.”

Ola Källenius, CEO of Daimler AG and Mercedes-Benz AG

”The EQS is the world's most aerodynamic production vehicle, with a drag coefficient of just 0.20. This contributes to its electric range of up to 770 kilometers according to WLTP. And with a fast-charging capacity of up to 200 kW, up to 300 kilometers of range can be added in just 15 minutes. All this, together with new battery chemistry, results inaperfect balance between performance, efficiency, range and ease of charging. And its technology goes beyond electric driving: Thanks to its comprehensive sensor technology and intelligence, the EQS sees practically everything around itandbecomes a co-pilot. Our customers therefore get more comfort both on long-distance trips and in large, busy cities.”

Markus Schäfer, Member of the Daimler AG and Mercedes-Benz AG Boards of Management; Daimler Group Research and COO Mercedes-Benz Cars

”The EQS is amilestone on the way to CO2-neutrality and our plan for a climate-neutral new car fleet. Ourgoal is to minimize our impact on the planet. We do this, for example, byusing an increasing proportion of recycled and renewable raw materials. We also help the customer to minimize their carbon footprint with our new function Green Charging. This feeds asmuch green electricity back into the grid as the Mercedes-EQ needs to charge”.

Britta Seeger, Member of the Daimler AG and Mercedes-Benz AG Boards of Management, Marketing & Sales

”Thanks to MBUX, our vehicles these days have become mobile assistants. In the EQS, we go a few steps further:Here, clever supporters suchas navigation withElectric Intelligence areintegratedinto MBUX, making iteveneasier to use. At the same time, the Hyperscreen and zero-layer concept show how stylish, individual and at the same time simple the operation of even complex content can be”.

Sajjad Khan, Member of the Board of Management of Mercedes-Benz AG and CTO

“With our EQS, we have created a completely new, future generation of luxury cars. Based on our style of sensual purity, we create desire by combining a beautifully seductive sculpture with the most progressive proportion. Key features such as the 'one-bow' design and a holistically integrated, highly reduced and seamless styling gives the EQS its sporty andprogressive look. That's what sets it apart from any other vehicle we have ever created - that's what makes our EQS so extraordinary.”

Gorden Wagener, Chief Design Officer of Daimler Group

“Our electric initiative is in full swing. With the EQE business sedan and the SUVvariants of the EQS and EQE, further models based on the new architecture will follow soon.”

Christoph Starzynski, Vice-President Electric Vehicle Architecture

Interesting facts & figures

The new EQS: at a glance

Depending on the size of the battery and the vehicle equipment and configuration, WLTP ranges of up to 770 kilometers1 are possible.

The path to the aerodynamics world record of the EQS required several 1000 calculation runs in the virtual wind tunnel with approx. 700 CPUs per calculation. With a cd  figure from 0.202  the EQS is the world's most aerodynamic production car. The frontal area of the EQS is 2.51 m2. This results in an effective air resistance from 0.5 m².

The momentum delivered to the wheels by the eATS is checked 10,000 times per minute and set if necessary. This enables a much faster response in the versions with 4MATIC than with mechanical all-wheel drive.

The modular drive concept allows a wide range of maximum total drive powers from 329 hp to 516 hp. A performance version with up to 630 hp is being planned.

Of the maximum deceleration in the DAuto recuperation program of 5 m/s², up to 3 m/s² is achieved by recuperation (2 m/s² by the wheel brakes). This allows decelerating to a standstill without using the brake
pedal, while at the same time the range benefits from this recuperation strategy and the high recuperation power (up to 290 kW3).

On request, the EQS has four automatic comfort doors4. Via MBUX, the driver has the option of opening the passenger and rear doors remotely - letting children get in at school, for example.

The standard rear-axle steering with a steering angle of up to 4.5° contributes to the agile and dynamic impression of the EQS. Alternatively, rear-axle steering with a steering angle of up to 10° can be ordered or subsequently activated by an upgrade over the air (OTA). This enables a turning circle of 35.7 feet for the EQS, which is over 16 feet long.

Mercedes me Charge has the densest charging network compatibility with over 500,000 charging points in 31 countries, including over 90% of public charging stations in the USA.

With the MBUX Hyperscreen, multiple displays merge seamlessly to create an impressive curved screen band over 56 inches wide. The area perceived by the occupants measures 2.6 sq. ft.

The large glass covering the MBUX Hyperscreen is curved in three dimensions in a molding process at temperatures of approx. 1202°F. This process allows a distortion-free view of the display unit across the entire width of the vehicle, irrespective of the radius of the glass cover.

Depending on the equipment, up to 350 sensors monitor the functions of the EQS or peer into the vehicle's surroundings, and that's not even counting the antennas. The sensors record, for example, distances, speeds and accelerations, lighting conditions, precipitation and temperatures, the occupancy of seats as well as the driver's blink of an eye or the passengers' speech.

The optional driving sound experience of the EQS is interactive and reacts to over a dozen different parameters such as the position of the accelerator pedal, speed or recuperation.

No.6 MOOD Linen is the name of the Air Balance fragrance composed especially for the EQS. It bears the number 6 because the first electric cars were added to the model range in 1906 with the "Mercédès Electrique" vehicles.

More than 40 new inventions have found their way into the EQS. In addition, 20 design applications protect the extraordinary design of the electric luxury sedan.

To get to the most important applications of MBUX, the user has to scroll through 0 menu levels. That's why it's called a zero layer.

The display area of the optionally available augmented reality head-up display corresponds to a screen with a diagonal of 77 inches. The imaging unit consists of a high-resolution matrix of 1.3 million individual mirrors.

The "Mercedes-Benz Star pattern" is used in several places in the EQS, for example, in the exterior as a special feature of the Black Panel front grille or in a light-alloy wheel design. In the interior, the Mercedes- Benz pattern can be found in the laser-cut backlit trim elements or on the front passenger display as a digital decorative image. It is an abstracted, three-dimensional star pattern based on an early trademark of the Daimler Motorengesellschaft (DMG), which was entered in the trademark registry on February 9, 1911.

The HEPA filter (High Efficiency Particulate Air) as part of the optional equipment ENERGIZING AIR CONTROL Plus with a volume of 0.35 cubic feet cleans the incoming outside air at its very high filtration level. Over 99.65 percent of particles of all sizes are eliminated. Around 21 ounces of activated charcoal are used to neutralize odors. The adsorption area is equivalent to about 150 football fields.

For haptic feedback during operation, a total of 12 actuators are located under the touchscreen surfaces of the MBUX Hyperscreen. If a finger touches certain spots there, they trigger a tangible vibration in the cover plate.

The Burmester® surround sound system in the EQS comprises 15 speakers with a total output of 710 watts and produces an unusually expressive, natural sound - the Burmester "feel-good sound".

A coating onthe cover glass simplifies cleaning of the MBUX Hyperscreen. The curved glass itself consists of particularly scratch-resistant aluminum silicate.

The EQS is the first production car with a cd value starting from 0.205. In this way, it makes use of the advantages of the Purpose Design.

8 CPU cores, 24 GB RAM and 46.4 GB per second RAM memory bandwidth are some of the MBUX technical data.

The brightness of the MBUX Hyperscreen's screen is adjusted to the ambient conditions using the measurement data from 1 multifunction camera and an additional 1 light sensor.

With up to seven profiles, the display area of the MBUX Hyperscreen for the front passenger can be individualized.

Hey Mercedes" supports 27 languages with Natural Language Understanding (NLU).

”Linking intelligence and emotion”

Short interview with Christoph Starzynski, Vice-President Electric Vehicle Architecture

Christoph Starzynski is responsible for the Mercedes-EQ models at Mercedes-Benz. Since 2002, the graduate in business administration has held various positions in the Daimler Group in Germany and abroad. We spoke to the 46-year-old about Mercedes-EQ's global strategy and future models.

Mr. Starzynski, one Mercedes-EQ premiere follows the next in 2021: first you presented the EQA, the all-electric brethren of the GLA, now the EQS, the new luxury-class model, andinbetween the seven-seater EQB is celebrating its debut. How is it that Mercedes-EQ is taking off in the compact and luxury class at the same time?

Starzynski: You're right, our electric initiative is in full swing. But we also have ambitious goals: by as early as 2030, the company wants more than half the cars it sells to feature electric powertrains - this includes all- electric vehicles and plug-in hybrids. And the list is far from complete: with the EQE business sedan and the SUV variants of the EQS and EQE, further models based on the new architecture will follow soon.

You address the architecture. The EQSis the first model to use the new all-electric platform. What are the advantages of this purpose design?

Starzynski: This new architecture is scalable in every respect and can be used across models. The wheelbase and track as well as all other system components, especially the batteries, are variable thanks to the modular design. This vehicle architecture makes Mercedes electric cars from sedans to large SUVs possible in the luxury segment. Thanks to the corresponding synergy effects, we can react very quickly to customer requests - for new electric vehicles, but also during a life cycle for variants with, for example, the next generation of batteries. And in terms of design and space, an all-electric platform naturally offers customers major advantages.

Mercedes-EQ has recently become a sub-brand like Mercedes-AMG or Mercedes-Maybach. Does this reflect the increased importance of electromobility at Mercedes?

Starzynski: Yes, 'Electric First' is our mission statement. And Mercedes-EQ is not just about extending traditional Mercedes-Benz virtues such as safety, responsibility, perfection and fascination by using new technology such as the electric powertrain. But also the linking of intelligence and emotion is centrally anchored in Mercedes-EQ. We want to accompany our customers into a world of new possibilities. This also includes software updates and the activation of new vehicle functions over the air (OTA). In addition, our approach to sustainability is holistic. In this way, we are actively contributing to the reduction of CO2 emissions and, with our Ambition 2039, are paving the way to the carbon-neutral mobility of the future.

Keyword future: Where do we go from here? Will the next generation of compact electric cars also be on a redesigned platform?

Starzynski: Our engineers are currently working on another electric vehicle platform, the Mercedes-Benz Modular Architecture (MMA) for vehicles in the compact and mid-size segments. In 2025, the first MMA-based models will arrive and complete our electric vehicle portfolio.

And has the range of up to 770 kilometers (WLTP) of the EQS 1reached the end of the line?

Starzynski: First of all, we are very pleased to have achieved this excellent and, above all, highly customer- relevant range figure. Many employees from very different departments have contributed to this: aerodynamicists and designers with the new world record for cd value, our battery specialists with higher energy density and software developed in-house, plus the valuable work of other experts that has resulted in excellent recuperation and really clever navigation with Electric Intelligence ...

But back to your question: No, it doesn't stop at 770 kilometers1. We have already announced the next step with the Vision EQXX technology program. Our development department is tasked with pushing the boundaries of range and efficiency. That's why we've put together a cross-functional and multi-disciplinary team in Stuttgart, supported by specialists from the British Mercedes-Benz F1 HPP Group. The colleagues contribute their expertise in electric motors as well as their motorsport-inspired development pace.

Innovations from this technology program will be rapidly transferred to series production models.

Interesting facts & figures

The new EQS: sustainability at a glance

When charging via Mercedes me Charge, 100 percent of the energy comes from renewable resources. In order to promote the use of green electricity, Mercedes acquires guarantees of origin in the required quantity. For the first two years after vehicle purchase, there is no added cost to customers for Green Charging.

The cobalt content in the cathodes of the battery cells of the EQS is less than ten percent and has been significantly reduced compared to previous battery generations.

The roof of Factory 56, EQS's production facility, is equipped with 12,000 photovoltaic modules. These have a maximum output of around 5000 kWp and can thus cover around 30 percent of the factory's energy needs on an annual average. All in all, the energy requirement of Factory 56 is 25 percent lower than that of other assembly buildings. The bottom line is that Factory 56 will be a zero-carbon factory - completely CO2-neutral.

The components of the EQS made proportionately from resource-saving materials (recycled and renewable raw materials) weigh 176 lbs.

With a cd figure from as low as 0.201, the EQS is the world's most aerodynamic production car. Compared to an aerodynamically good electric car (cd value 0.23), this delivers a range advantage of four (WLTP cycle) to five percent (Mercedes long-distance measurement).

40 percent ofthe roof area of Factory 56 is greened, and recycled concrete was used for the first time in the head building.

In 2022, globally a total of eight Mercedes-EQ electric vehicle series will already be produced at seven locations on three continents.

Since 2005, Mercedes-Benz has subjected its vehicles to the stringent requirements of an environmental certificate in accordance with ISO standard TR 14062, now known as the 360° Environmental Check.

In total, the Mercedes me Charge network has access to over 500,000 charging points, of which over 200,000 are in Europe and over 90% coverage of public charging points in the USA.

The floor coverings use a new yarn made of regenerated nylon. One ton of this yarn saves over 6.5 tons of CO2 compared to all-new material.

The steel processed for the EQS at the Mercedes-Benz stamping plants consists of 80 percent secondary steel, most of which is obtained from recycled steel scrap.

The battery warranty confirms a long service life of the high-voltage batteries. It is valid up to a term of ten years or up to 155,000 miles.

The majority of suppliers, who account for more than 75 percent ofthe annual purchasing volume, want to supply only CO2-neutrally produced parts in the future. They have declared their willingness to do so in an ambition letter.

Mercedes-Benz already started to create transparency in the complex cobalt supply chains for battery cells in 2018. For this purpose, 120 suppliers were identified and 60 audits were carried out according to the guidelines of the OECD (Organization for Economic Co-operation and Development).

The production of the highly complex lithium-ion batteries at the Hedelfingen plant, part of the Mercedes-Benz site in Stuttgart-Untertürkheim, will be CO2-neutral from 2022. As part of strategic partnerships, Mercedes-Benz has also agreed to purchase battery cells manufactured in a CO2-neutral manner, starting with the EQS.

The transformers: thinking of tomorrow today

The new EQS: sustainability

As part of "Ambition 2039", Mercedes-Benz is working to offer a carbon-neutral new car fleet in less than 20 years, which is eleven years earlier than EU legislation currently requires. By as early as 2030, the company wants more than half the cars it sells to feature electric drive systems - this includes fully electric vehicles and plug-in hybrids. In many areas, Mercedes is already thinking about tomorrow, today: the new EQS is designed to be correspondingly sustainable. The vehicles are produced in a CO2-neutral manner at Factory 56, and resource-saving materials such as carpets made from recycled yarn are used. This is because Mercedes-Benz considers the entire value chain, from development and the supplier network to its own production. Mercedes-Benz AG has had its climate protection targets confirmed by the Science Based Targets Initiative (SBTI). With these goals, the company supports the Paris Climate Accord.

Eleven important building blocks of the transformation towards sustainable mobility.

1. Electrified product portfolio

Mercedes-Benz is aiming for the leading position in electric powertrains and vehicle software. Ambition 2039 describes the goal of a fully connected and carbon-neutral vehicle fleet in 2039. In 2022, globally a total of eight Mercedes-EQ electric vehicle series will already be produced at seven locations on three continents.

The company envisages that more than 50 percent of its passenger car unit sales will be accounted for by plug-in hybrids or all-electric vehicles by 2030.

2. Transparent dialogue

Since 2005, Mercedes-Benz has been the first company ever to subject its vehicles to the strict requirements of an environmental certificate in accordance with ISO standard TR 14062. The TÜV-certified documentation is based on a comprehensive life-cycle assessment of the respective vehicle, in which every environmentally relevant detail is documented. The Group's sustainability report has provided detailed information on this topic every year since 2006. And the Daimler Sustainability Dialogue has been bringing together sustainability experts from various fields with Daimler representatives every year since 2008. Current and future sustainability issues are discussed in workshops, progress as well as deficits and risks are evaluated and resulting needs for action are defined. In November 2020, the Daimler Sustainability Dialogue brought together over 200 representatives from business, science, politics, NGOs, associations, trade unions and local authorities in the digital space.

3. Production in Factory 56 – efficient, flexible, digital and sustainable

The EQS rolls off the production line at Factory 56 in Sindelfingen, Mercedes-Benz's most modern automotive production facility. In line with the Ambition 2039, Factory 56 will become a zero-carbon factory - completely carbon-neutral and with a significantly reduced energy requirement. Overall, the energy requirement in Factory 56 is reduced by a quarter compared to other assembly buildings. On the roof of Factory 56 is a photovoltaic system which supplies the shop with self-generated, green electric power. This is able to cover around 30 percent of the annual power requirement of Factory 56. Some of this power flows to an innovative direct current network which will improve the energy efficiency of the assembly shop during operation in the future. This powers infrastructural systems such as ventilation units for example. A stationary energy bank based on starter batteries is also connected to the DC network. With an overall capacity of 1400 kWh, it acts as a buffer for superfluous solar power from the photovoltaic system. Mercedes-Benz's approach to sustainability also encompasses other ecological aspects. 40 percent of the roof area of Factory 56 is greened, and recycled concrete was used for the first time in the head building.

4. Carbon-neutral production

Mercedes-Benz's own plants will have carbon-neutral production from 2022. To achieve climate-neutral production, the first step is to consistently reduce and, where possible, completely avoid emissions that are generated in Mercedes-Benz vehicle production and in the energy supply of the plants. The company relies on three strategic pillars for doing so: continuous increase in energy efficiency, use of green power and realization of a sustainable heat supply. Starting in 2022, all own production plants of Mercedes-Benz AG around the world will obtain electricity exclusively from renewable sources. In addition, concrete CO2 measures are agreed with suppliers. Logistics are an essential part of this supply network: at the beginning of 2020, rail transport in Mercedes-Benz transport logistics was converted to a carbon-free energy supply in cooperation with Deutsche Bahn.

5. Sustainable battery production

Local battery production is a major success factor in the strategic electric initiative of Mercedes-Benz AG – and a crucial element when it comes to being able to flexibly and efficiently serve the global demand for electric vehicles. Production plays a decisive role in Mercedes-Benz AG's understanding of sustainability. For example, the Mercedes-Benz Hedelfingen plant will produce battery systems in a carbon-neutral manner from 2022. Mercedes-Benz has also agreed to purchase carbon-neutral battery cells as part of strategic partnerships, starting with the EQS.

6. Decarbonization of the supplier network

The supplier network accounts for a substantial share of value creation, and is therefore of decisive importance for the decarbonization targets. A large number of suppliers, who account for more than 75 percent of the annual purchasing volume, have already signed an Ambition Letter and have agreed to only supply parts produced in a CO2-neutral manner in the future. From 2039 at the latest, only production materials which have been produced on a carbon-neutral basis in all value creation stages will be allowed through the plant gates of Mercedes-Benz. A supplier declining to sign the Ambition Letter will not be eligible for new supply contracts.

7. Raw materials from certified mining

Mercedes-Benz looks at the entire value chain, from development and the supplier network to its own production. Responsibly mined and processed raw materials provide the foundation for a sustainable Mercedes-Benz electric vehicle fleet. Mercedes-Benz has therefore had the complex supply chains of battery cell suppliers audited in accordance with OECD standards and will in future only purchase battery cells with cobalt and lithium from certified mining. In addition, Mercedes-Benz is making the "Standard for Responsible Mining" of the "Initiative for Responsible Mining Assurance" (IRMA) a key criterion for supplier decisions and contracts in raw material supply chains and will only work with suppliers who agree to these requirements.

8. Resource-conserving materials

EQS components with a total weight of more than 80 kg are proportionally manufactured from resource- saving materials (recycled and renewable raw materials). For example, the cable ducts are made of recycled plastic, the floor coverings are made of a recycled yarn (brand name ECONYL®) and the aluminum for the inner part of the front hood has already been certified as sustainably produced by the Aluminum Stewardship Initiative (ASI).

9. Highly efficient aerodynamics

With a cd figure (drag coefficient) from as low as 0.201, the EQS is the world's most aerodynamic production car. The low air resistance pays off, for example, in the range (up to 770 km according to WLTP)2.

10. Green power for on the move

With Mercedes me Charge, customers have been charging green at every public charging station throughout Europe since 2021. After the actual charging process, the charged energy quantities are compensated with green power and, in addition, incentives are created to invest in renewable energy systems. In the first two years after the purchase of an EQS, there is no basic fee to customers for Mercedes me Charge and thus for Green Charging.

11. Sustainable battery use

Second life assured: Mercedes-Benz takes a holistic approach to the battery life cycle: Re-Use, Remanufacture, Recycle. Once the traction batteries of the Mercedes-EQ fleet reach the end of their life on the road, it's far from over. Mercedes-Benz Energy, based in Kamenz, is a subsidiary of Mercedes-Benz AG responsible for the development of innovative energy storage solutions. By building stationary energy storage systems, electric car batteries can be connected to the grid. The spectrum for large-scale storage applications from Mercedes-Benz Energy ranges from peak load balancing and black start (power plant start-up independent of the power grid) to uninterruptible power supply (UPS). The company's focus is in particular on applications from the 2nd-life and replacement parts storage unit sector. Only then is it time for material recycling.

Innovative aesthetics in unmistakable purpose design

The new EQS: the exterior design

The EQS is the first all-electric premium sedan from Mercedes-EQ. The innovative and holistic design is based on a new vehicle architecture. It differs from vehicles with internal combustion engines at first glance: high demands for function and aerodynamics are combined with innovative aesthetics in the unmistakable purpose design. Sensual Purity is reflected in generously molded surfaces, reduced joints and seamless transitions (seamless design).

The sporty, low and slim front of the EQS forms a coupe-like silhouette with a bow (one bow) stretched tightly over the greenhouse. The A-pillar, which has been moved far forward, and the C-pillar at the rear generate generous space for the passenger compartment. Unique in this segment is the cab-forward design: the overhangs and the front-end assembly are short, the rear is smoothly rounded. The flush-positioned wheels measuring just under 30 inches in size and ranging from 20 to 22 inches, give the EQS a sporty character in agreement with a muscular shoulder section.

The design philosophy of Sensual Purity is implemented with the clear, generous and surface-emphasizing molding. Seamless design is realized with reduced lines, precise joints and flowing transitions.

Aerodynamics and formal aesthetics go hand in hand. The detailed design expresses innovation and exclusivity.

Black Panel front with Mercedes-Benz pattern on request
The front is combined into a 'Black Panel' unit. Innovative headlights connected by a light band and the deep black radiator grille (Black Panel) form the distinctive face. This makes the EQS the model for a new luxury- class generation from Mercedes-EQ. Three light dots, a symbol of vehicles in the S-Class family, combined with the characteristic Mercedes eyebrow, form the striking daytime running light signet. The standard DIGITAL LIGHT headlamps are connected by a LED lightband that stretches across the entire front of the grille.

The exclusive look of the Black Panel radiator grille with central Mercedes star is enhanced further: and include the Mercedes-Benz Star pattern, a three-dimensional star pattern. This references the original star of the Daimler- Motorengesellschaft company, which was registered as a trademark in 1911. In addition to its unique look, there is also a function behind the Black Panel surface: the various sensors of the driver assistance systems such as ultrasound, camera, radar and lidar (laser) are integrated there. Seamless design is particularly evident in the front-end design with its reduced gap pattern and an overlapping hood - it does away with the traditional separation between the front hood and fenders.

Striking one-bow line
The aerodynamic silhouette with frameless, coupe-like doors and the high, arched beltline are independent design elements in the profile. The exterior mirrors sit on the beltline and are aerodynamically and aero- acoustically optimized. Chrome accents highlight design focal points like the one-bow line of the window graphics. High-quality painted contrasting surfaces can be found in the lower area of the vehicle.

Flush door handles are standard on all models. The power tilt and sliding panorama roof also comes standard on the EQS, it consists of two modules that together form a large glass surface and thus provide an airy and light feeling in the interior. A power fabric shade is integrated into the panorama roof, which can be closed for additional sun protection.

A service port for windshield wiper fluid is integrated into the side of the left fender, allowing easy and convenient access to fill the reservoir.

Lighting strip with LED lamps in 3D helix design
The round, coupe-like rear end is gracefully designed, in contrast to this is a rear spoiler that boasts a sharp spoiler lip. The flush tailgate is integrated almost seamlessly with precise gaps. The rear camera is hidden behind the star, protected from dirt. The highlight at the rear are the innovatively designed LED lamps: Their insides have the shape of a curved and illuminated 3D helix. As at the front, the EQS also has a continuous light band at the rear - a distinguishing feature of Mercedes-EQ vehicles.

Paintwork with high-quality effect pigments
The EQ-specific exterior paints Twilight Blue Metallic and Sonoran Brown Metallic emphasize the one-bow line and give the EQS a dynamic appearance thanks to eye-catching pigments.

Here are the most important differences between the design and equipment lines:

Embarking on the new era of purpose design

The new EQS under the magnifying glass: the design concept (exterior)

Although the EQS is a close relative of the new S-Class, it is built on an all-electric architecture. This completely new concept made a Purpose Design possible: with its one-bow lines and cab-forward design with fastback, the EQS is clearly distinguishable from vehicles with combustion engines even at first glance. This is further emphasized by the Black Panel front and the design of the front and rear lights.

Highest standards on function and aerodynamics go hand in hand with innovative aesthetics. The design philosophy of Sensual Purity, combined with Progressive Luxury, is reflected in generously sculpted surfaces, reduced joints and seamless transitions (seamless design).

Here are the most important keywords about the exterior design of the EQS:

Purpose design: electric cars can either be based on an existing (combustion engine) platform ("conversion design") or, like the EQS, on an all-electric architecture ("purpose design"). This complete and consistent new concept allows freedom in the arrangement of the components and a radically different design. This leads to advantages in packaging and ergonomics for the EQS. The purpose design with smooth underbody and mostly closed radiator shutter as well as the favorable shape served as a solid starting point for the flow optimization. With a lot of meticulous detail work, the aerodynamicists, in close cooperation with the designers, were able to achieve the new best cd value starting from 0.201.

One-bow design: the roofline above the passenger compartment, the greenhouse, is as taut like a bow ("one bow") in the EQS. A coupe-like silhouette is created in conjunction with the sportily low and slim front. This is underlined by the frameless doors and a high, curved beltline as an independent design element.

Cab-forward design ("cab placed in front"): The far-forward base of the A-pillar and the C-pillar at the rear create space in the EQS for a generously dimensioned passenger compartment. The overhangs and the front- end assembly are short while the rear is smoothly rounded.

Seamless design: body creases have had their day at Mercedes-Benz. With reduced lines, precise gaps and flowing transitions, the designers have realized the new purism in the EQS in superior styling. An exemplary element is the front-end design: the front hood overlaps the fenders. This also reduces the number of visible panel gaps.

Black Panel front: the deep black surface of the grille ("Black Panel") defines the striking face of the EQS. The Black Panel unit at the front is a design feature of the Mercedes-EQ model family.

Mercedes-Benz Star pattern: abstracted, three-dimensional star pattern based on the original three-pointed star, the early trademark of Daimler Motorengesellschaft (DMG). The company had applied for a utility model for a three-pointed star in 1909; it was entered in the trademark registry on February 9, 1911. The three- pointed star was used immediately and after a short time was already one of the best-known trademarks in the world. The star first received a wreath in 1916. The pattern is used in several places in the EQS, for example, in the Black Panel grille front or in a light-alloy wheel design. In the interior, the Mercedes-Benz pattern can be found in laser-cut backlit trim elements or on the front passenger display as a digital decorative image.

Light design: the headlights have a striking daytime running light signet with three light dots and are connected to each other via a light band. This is just as defining for the EQ family as the lights at the rear: the rear lights are also connected by a light band, with inner workings in the form of a curved 3D helix.

The EQS: Experience for all the senses

The new EQS under the magnifying glass: see, hear, smell, and feel

The EQS can be experienced with almost all the senses. This elevates the all-electric top-of-the-range model to a new dimension in aesthetics and luxury. Seeing, hearing, smelling, feeling and tasting, these are the classic human senses. The new EQS appeals to the first four in many ways:

Visual perception: over 100 million rods and cones are located in the retina of the human eye. These sensory cells enable us to see, for example, the features of the EQS that are revolutionary for the luxury class, such as the cab-forward design or the coupe-like "one-bow" lines with fastback. This clearly distinguishes the EQS from vehicles with combustion engines from the first glance and is further emphasized by the Black Panel in the front and the design of the lights.

The designers had the mission and the chance to tread a completely new path in styling the interior. They made use of this freedom: the MBUX Hyperscreen is one of the highlights in the new EQS. The concave screen stretches out in front of the occupants from the left to the right A-pillar like an ocean wave. Besides the sheer size, the high-quality, detailed design also guarantees a "wow" effect. The MBUX Hyperscreen is integrated into the instrument panel in minimalist fashion. Only a thin silver shadow frame, a vent band and a narrow frame surround it. The vent band spans across the entire width at the top and features rose gold accents.

These extreme proportions, together with the glass wave of the MBUX Hyperscreen, create the Avant-garde architecture of the cockpit. The calm and clear design of the door panels borrows from the interior design of modern living spaces. Avant-garde as well as traditional materials and colors give the interior a special atmosphere. Another visual highlight is the head-up display with augmented reality content.

Auditory perception: The listening impression of the EQS ranges between comfortable silence and an interactive, emotional sound experience. With a holistic sound production, the sound experts from Mercedes have made the paradigm shift from the combustion engine to the electric car acoustically perceptible. The EQS comes from the factory with two soundscapes: Silver Waves and Vivid Flux. They can be selected or switched off as sound experiences on the central display. The driver and passengers are greeted with a welcome sound when approaching the vehicle and when getting in. A corresponding aura sound also accompanies exiting and locking the EQS. The driving sound is produced by the speakers of the sound system in the interior. The new ENERGIZING NATURE programs of ENERGIZING COMFORT also offer an impressively realistic listening experience. The soothing sounds called Forest Glade, Sounds of the Sea and Summer Rain were created in cooperation with nature acoustician Gordon Hempton. As with the other ENERGIZING COMFORT programs, other senses are addressed with ambient lighting and images. Streaming services are another alternative to the new type of silence and interactive driving sound in the car: Mercedes-Benz has fully integrated the major music streaming services into the MBUX infotainment system with the "Online Music" service.

Olfactory perception: scents are constantly being introduced when we breathe. The EQS protects against unpleasant odors: its large HEPA filter (High Efficiency Particulate Air) not only cleans the outside air very effectively of fine dust, minute particles and pollen. Special activated charcoals in the HEPA filter and the interior air filter also filter out sulphur dioxide and nitrogen oxides as well as odors. Due to their pore structure, they have a very large inner surface area. Around 21 ounces of activated charcoal are used in the HEPA filter of the EQS. The adsorption area is equivalent to about 150 football fields.

The AIR-BALANCE Package, also appeals to the sense of smell. A new fragrance has been composed for the new top-of-the-range electric model: No.6 MOOD Linen - carried by the green note of a fig and linen.

Haptic perception: There is a lot to feel in the interior of the EQS: flowing leather surfaces with intricate seam patterns or dynamic perforation; the modern fine structure NEOTEX, which combines the look of nubuck leather and high-tech neoprene; trim elements made of real natural grain wood or additional innovative trims. The MBUX Hyperscreen's central and front passenger displays also offer haptic feedback. If a finger touches certain points on the touchscreen, the user feels pulses on the smooth surface that give the impression of a mechanical switch. Another operating aid is the force feedback of both displays, which allows for different levels of pressure on the glass to change the response. For example, with added pressure MBUX then jumps to another menu level. Finally, there are up to ten different massage programs in the EQS that can be felt with the whole body. The seat features inflatable air chambers that can be enhanced with heating for a “Hot Stone” massage. The vibration motors in the seats also enhance the effect of a relaxing massage.

Here comes the new world record holder

The new EQS: Aerodynamics

Less resistance for increased range and quiet: With a cd value from 0.20,1 it sets a new aerodynamic benchmark for production vehicles, resulting in improvements for the range. It is also among the best in terms of quiet running. A great deal of attention to detail lies behind the aerodynamic and aeroacoustic performance.

The purpose design with smooth underbody and mostly closed radiator shutter as well as the favorable basic shape were a solid starting point for the flow optimization. With a great deal of meticulousness, the aerodynamicists in close cooperation with designers were able to achieve the new record cd value of 0.20.

The frontal area of the EQS is 2.51 m2. This results in an effective air resistance from 0.5 m².

The spread of the individual variants in terms of cd value is comparatively small - customers thus have a wide choice of models without having to consider the range. Mercedes also offers aero wheel options, which were optimized in the wind tunnel, in 20 and 21 inches.

Behind the aerodynamic performance required a lot of attention to detail. The EQS is the first representative of the new electric platform. This is why the invisible details, such as those on the underbody, were developed diligently with great attention to the smallest details. Several thousand computational runs were performed in the virtual wind tunnel alone. Below are some details of the aero development:

  • Aerodynamically favorable dimensional concept and tires with optimized geometry
  • Aerodynamically optimized wheels in the dimensions 20 and 21 inches
  • Cooling air control system with innovative transverse lamella makes extremely efficient use of the available installation space
  • Continuous seals in the front area, i.e. between service flap, Black Panel and headlamps
  • Streamlined design of the A-pillar
  • Wheel spoilers at front and rear. The rear, arrow-shaped wheel spoiler was developed by a fluid dynamics expert directly in the wind tunnel for the benefit of a greater range.
  • Elaborately matched underbody paneling in the rear-axle area to take even greater advantage of the smooth underbody of the battery.
  • The rear spoiler benefits both rear-axle lift and aerodynamic drag.

For more than three decades, the aerodynamicists at Mercedes-Benz have been achieving top results. Currently, the A-Class Sedan (V 177) and the S-Class (V 223) are the worldwide record holders with a cd value of 0.22. The special simulation tools and the Mercedes-Benz aero-acoustics wind tunnel commissioned in 2013 make a decisive contribution to this. The EQS also received its fine-tuning there.

Extensive sealing and insulation measures reduce wind noise
In an electric car without the usual level of powertrain sound, wind noise is particularly noticeable by the occupants. That is why the aeroacoustic behavior is particularly important.

In this area, the new EQS is one of the very best vehicles in its class.
New solutions had to be found due to the concept-related lack of a partition between the interior and the trunk and the aluminum alloys used in many places. Low-frequency noise, which can be perceived as reducing comfort, is prevented by filling numerous cavities in the body with acoustically effective foam.

Reduction of the high-frequency components of the wind noise was made possible with specific measures taken on the door and window seals. Special attention was paid to the sealing of the transitions between the six side windows.

The seals on the flush-fitting door handles, the window support and on the raised exterior mirrors are also noise-optimized.

A further contribution was made by the newly developed A-pillar with a specially shaped piece of trim at the transition to the windscreen. The development is supported by both modern flow simulations and external noise measurements using a special microphone array in the wind tunnel. The A-pillar is designed in this way not only to improve the aero-acoustics, but it is also important for a low cd value and to keep the windows free of dirt.

For further enhanced quiet running, a specially developed Acoustic Comfort Package has been integrated into standard equipment. This includes additional insulation measures in the interior. As an additional option, laminated safety glass panels at the side and rear provide additional acoustic and heat protection. The optional acoustic glass mainly reduces wind noise even further, but also does so for noises coming in from the outside (for example, tire noise or passing/oncoming vehicles). Particularly on longer journeys or highway journeys, the driver remains more relaxed and the passengers feel more comfortable as a result.

On the standard panoramic roof, various wind deflection measures (wind deflectors, covers and seals with optimized geometry) ensure a high level of quiet running despite the large opening area of the roof.

Refinement of the new school

The new EQS: the automatic comfort doors

As an option1, the EQS has automatic comfort doors at the front and rear. When the driver approaches the car, first of all the door handles extend. As they approach closer, the driver's door opens automatically.

Using MBUX, the driver is also able to open the passenger and rear doors, for example, to let in children in the school carpool line. With one-touch operation, the automatic comfort doors can be closed conveniently and with little effort. The sensors of the parking assistance systems are used for obstacle detection. Their integration with Blind Spot Assist provides additional safety.

For the new EQS: Its automatic comfort doors make entry and exit particularly convenient. Because with this optional equipment, all four doors are electrically powered and open and close automatically. If desired, the EQS can even open and close the driver's door like a chauffeur. If the driver approaches the EQS from the side, the door handle first extends at a distance of approximately 20 feet. If the distance is only about 5 feet, the car unlocks and automatically opens the driver's door. This special welcome function can be activated or deactivated via MBUX.

The comfort doors are available as an option. The comfort doors can be operated in many ways: traditionally via the door handles (inside and outside), by the vehicle key, or via the central display. In addition, the driver's door closes automatically when the brake pedal is depressed.

The comfort doors also come with obstacle detection. Opening is monitored by Blind Spot Assist if it is active: If the system detects that another road user is approaching from behind, a vehicle exit warning is given. The doors only open when it is safe to do so.

To protect against damage, the car also uses data from the parking sensors. If the EQS has the automatic doors, ultrasound sensors monitor the surroundings when parking. In combination with the standard Parking Package with Surround View camera, observation is also provided by cameras in the exterior mirrors. The EQS then takes detected obstacles into account when opening the doors. Proximity sensors in the doors are also active when the vehicle is stationary. They also scan the environment while opening.

There is an electric actuator on the catch strap in each door. The doors are then swung open and closed in a controlled manner on command from the door control panel. The comfort doors were required to undergo extensive testing in true Mercedes-Benz fashion. Before being made to demonstrate their operating convenience and reliability in overall vehicle trials, they were tested on various test rigs including the climatic chamber. Naturally, their acoustic properties and safety functions were also thoroughly tested.

No cable reaches this far

The new EQS: Electric powertrain1:

Nonstop from Munich to Berlin or from Oslo to Stockholm: with an operating range of up to 770 kilometers (WLTP) and an output of up to 385 kW, the powertrain of the EQS meets every expectation of a progressive sedan in the S-Class segment. All EQS models have an electric powertrain (eATS) at the rear axle, while the version with 4MATIC also have an eATS at the front axle. In the 4MATIC model, the Torque Shift function ensures intelligent, continuously variable distribution of drive torque between the rear and front electric motors and thus the use of the most efficient eATS in each case. The modular powertrain concept ensures high overall performance and long range.

The modular drive concept allows a wide range of maximum total drive powers from 329 hp to 516 hp. A performance version with up to 630 hp is being planned. Depending on the vehicle equipment and configuration, WLTP ranges of up to 770 kilometers are possible.

The electric motors on the front and rear axles are permanently excited synchronous motors (PSM). With the PSM, the rotor of the AC motor is fitted with permanent magnets and therefore does not need to be supplied with power. The magnets – and thus the rotor – follow the rotating alternating current field in the winding of the stator. In the EQS, Mercedes-Benz uses a pull-in winding for a particularly strong magnetic field. The engine is described as synchronous, because the rotor turns at the same rate as the magnetic field of the stator. The frequency is adjusted in the power electronics convertors to the speed requirements of the driver. The advantages of this design include high power density, high efficiency and high power constancy. The motor on the rear axle is particularly powerful due to its six-phase design: It has two windings with three phases each.

Cooling: sophisticated thermal concept for high load capacity
Consistently high performance and multiple accelerations without a drop in power characterize the drive philosophy of the EQS. This includes a sophisticated thermal concept with some special features. A water lance in the shaft of the rotor cools it from the inside. Other cooling elements in the cooling circuit are fins on the stator, a needle-shaped pin-fin structure on the inverter and a transmission oil cooler. This also brings more efficiency during cold driving, because the heat exchanger then serves to heat the transmission oil and thus reduces friction in the transmission.

Intelligent recuperation: one-pedal driving to a standstill
The EQS offers several variants of energy recovery: In this process, the high-voltage battery is charged by converting the mechanical rotary motion into electrical energy during push or braking operation. The driver can manually select the deceleration in three stages (D+, D, D-) and the coast function via shift paddles behind the steering wheel. Additionally, there is DAuto. In this program, up to 16 ft/s² deceleration is achieved, 10 ft/s² of which is due to recuperation (7 ft/s² via the wheel brakes). The recuperation power of the all-wheel drive versions is up to 290 kW2, and for rear-wheel drive vehicles, traction (and thus driving stability) is the limiting factor.

ECO Assist also offers situation-optimized energy recovery - deceleration is so strong or weak that it ultimately results in the most efficient driving style. Recuperative deceleration is also used as far as possible approaching detected vehicles ahead until they come to a standstill, for example at traffic lights. The driver does not need to press the brake pedal for this - pure one-pedal driving.

4MATIC model: infinitely variable distribution of the drive torques
With 4MATIC, the Torque Shift function intelligently and continuously distributes the drive torques between the front and rear axles. It thus ensures the use of the most efficient eATS in each case, as these can be regulated independently of each other. The required drive torque at the wheels is checked 10,000 times per minute and set if necessary: The reaction is thus much faster than would ever be possible with a mechanical all-wheel drive.

Extensive testing: special test benches at Mercedes-Benz
On its way to series production, the EQS covered around three million test miles, including at the Test and Technology Centre (PTZ) in Immendingen. The systematic validation of the overall vehicle serves to guarantee the high quality standards and is one of the extensive measures in the development process of every Mercedes-Benz model series. Stations included tough winter tests in Scandinavia, chassis and powertrain tests on proving grounds, public roads and on the high-speed test track in Nardò, as well as integrated complete vehicle heat testing in Southern Europe and South Africa. The EQS was also on the road for test drives in China, Japan, Dubai and the USA.

In the process, it completed the same demanding testing program as any other vehicle that can proudly wear a star. In addition, a number of tests were carried out specifically for electric cars, covering important development priorities such as range, charging and efficiency. Of course, special attention was paid to the e-drive and the battery.

In addition, there were several million test miles on a total of more than two dozen test benches in Stuttgart- Untertürkheim and at the development site in Nabern. Testing takes place on pure eATS test benches, where the current comes from a special direct current source, a battery simulation, and on eDrive test benches: Here, the testing also includes the battery and the complete charging components of the vehicle. The track profile/test bench profile was modified compared to the combustion engines, for example to take into account the torque load on the transmissions in both directions - a special load case determined by the high recuperation power. In addition, there is the special hot/cold testing of the power electronics.

Confirmed TÜV figures, EC type approval and conformity certification with official figures are not yet available. Differences between the stated figures and the official figures are possible.
2 This value refers to the electrical power fed into the electric battery due to recuperation. It can be achieved under optimal environmental conditions, depending on, among other things charge status and temperature. Deviations are possible.

The auditory whispering class

The new EQS: the noise and vibration comfort

The EQS is the all-electric member of the S-Class family. This means that it must meet the highest expectations for acoustic comfort. The specifications therefore already defined a number of measures, including special acoustic foams in some of the profiles of the shell as well as the encapsulation of the eATS at the front and rear. The drive units are doubly insulated using rubber mounts. At the front axle this takes the form of a supporting frame, with a subframe at the rear axle.

Starting with the design of the electric powertrains (eATS), NVH (noise, vibration, harshness) was a priority. The magnets inside the rotors are arranged in an NVH-optimized way (sheet metal cut). This also reduces the use of rare earths. The shape of the winding, the stator tilt, also supports vibration comfort, especially at low speeds. In relation to the permanent magnets of the rotor, the coils of the stator are obliquely wound. Otherwise, what is known as cogging torque could occur. This would lead to slight but unpleasant vibrations when driving at low speeds.

In addition, the eATS have a special foam mat all around as an NVH cover. The lid of the inverter has a sandwich construction of three metal and plastic layers. The eATS are doubly decoupled from the body via elastomer bearings: At the front axle opposite a supporting frame and this against the body, and a rear axle carrier.

Highly effective spring/mass components provide continuous sound insulation from the cross-member under the windscreen to the floor of the trunk. Acoustic foams are inserted into many carriers as early as the shell construction stage. Because the full-area main floor under the high-voltage battery is a component with a potentially high noise component, a new insulation part is used. A foam sealed in foil, enclosed in the seal of the battery lid, is clamped between the battery and the floor and prevents excitation. In addition, the main floor is designed with beads for NVH reasons. These prevent resonance of the surface and thus the occurrence of a corresponding structure-borne sound. Two acoustic dividers in the very large tailgate reduce boom noise. These could be caused by roadway disruptions and are favored by the large volume of the cab including the bulkhead-free luggage compartment.

Powerful cell chemistry meets intelligent software

The new EQS: the traction battery1

Modular, efficient and innovative: depending on the variant, sufficient energy can be stored for ranges of up to 770 kilometers according to WLTP. The innovative battery management software, developed in- house, allows updates over the air (OTA). The energy management of the EQS is therefore kept up to date throughout the life cycle.

Battery development is a decisive factor in Mercedes-Benz's electrification strategy. After all, the battery is the heart of an electric car and makes a decisive contribution to, among other things, the range and thus the driving characteristics of the electric vehicle. The EQS marks the launch of a new generation of batteries with significantly higher energy density and a usable energy content of 107.8 kWh (according to WLTP). The new battery sets standards in terms of performance, efficiency and charging capacity.

It also meets the high Mercedes requirements in terms of safety, durability and sustainability.
Mercedes-Benz issues a battery warranty for its high-voltage batteries and thus a performance promise to customers: A term of 10 years or 155,000 miles with a remaining capacity of 70 percent.

Comprehensive battery expertise
The highly efficient batteries were developed entirely in-house by the team of experts at the Mercedes-Benz Battery Center of Competence. The software for the intelligent management system was also developed and programed in-house. The batteries are produced in the Hedelfingen plant section at the Stuttgart- Untertürkheim site.

For battery variants, a major step has been achieved in terms of the sustainability of the cell chemistry: The optimized active material consists of nickel, cobalt and manganese in a ratio of 8:1:1. This reduces the cobalt content to less than ten percent. The continuous optimization of the recyclability is part of Mercedes- Benz's holistic battery strategy (for details, see separate chapter on sustainability). The aim is to be able to dispense entirely with materials such as cobalt through the use of innovative post-lithium-ion technologies.

Intelligent operating strategy for maximum range
The battery is integrated into the intelligent thermal management of the EQS. If the intelligent navigation with Electric Intelligence is activated, the battery is preheated or cooled as needed while driving to reach the optimal temperature for efficient charging at the charging point. The desired temperature range of the battery is achieved with the aid of the cooling circuit and a PTC (Positive Temperature Coefficient) booster heater integrated into it.

Complex protection concept for safety
In principle, Mercedes-Benz AG applies very high safety standards to all its models. This means that, in many cases, internal Mercedes-Benz safety standards exceed legal requirements. Especially the crash-related requirements are aligned to the real-life safety philosophy. In the process, findings from internal accident research are incorporated into the development specifications. Alongside verification of crash behavior, all Mercedes-Benz vehicles undergo additional component tests at the system level.

The battery sits in a crash-protected area in the underbody, embedded in the body shell structure including an extruded aluminum profile on the side. In extrusion, a heated block of metal is forced through dies and transformed into a continuous profile, which is then cut to fit. In this way, highly complex profiles can be produced that are precisely tailored to the requirements. The housing with energy absorbing structures at the front and side as well as a rigid, double-walled base plate provide additional protection for the modules. The test criteria include, among other things, the battery behavior under shock load and in the event of foreign object penetration. Overheating and overcharging were also simulated and tested. In addition, there is a separate, multi-level safety system for everyday operation. This includes, for example, temperature, voltage or insulation monitoring as a continuously monitoring safety system. If an error occurs, the battery is switched off.

Production: Battery systems from Hedelfingen
The batteries for the Mercedes-EQ electric vehicles are supplied by the global battery production network with factories on three continents. Local battery production is a key success factor for Mercedes-Benz's electric initiative.

The battery systems for the EQS are produced in the Hedelfingen plant section at the Stuttgart-Untertürkheim site. Absolute precision is required in their manufacture. The battery systems consist of a large number of components, including up to 12 cell modules and the EE compartment for intelligent integration of the power electronics. It is assembled at the Mercedes-Benz location in Berlin.

The Mercedes-Benz Hedelfingen plant will have carbon-neutral production from 2022. The Hedelfingen plant is a prime example of the transformation of production sites as part of the Mercedes-Benz Electric First strategy. The efficient and seamless integration of battery production alongside existing transmission production transforms Hedelfingen's traditional role as a site for conventional powertrain components into an important part of the company's global battery production network.

The suppliers of the battery cells have undertaken to use electricity from renewable energy sources such as hydropower, wind and solar energy in the production of the battery cells. The supplier network accounts for a substantial share of value creation, and is therefore of decisive importance for the decarbonization targets.

Already, around half of all suppliers have signed a corresponding declaration of intent. Because of the higher energy requirements in the production of all-electric vehicles, the supplier network is a crucial component in achieving Mercedes-Benz's climate targets.

Further reducing the carbon footprint with green power

The new EQS: Mercedes me Charge

With Mercedes me Charge, customers have been charging green at every public charging station throughout Europe since 2021. High-quality guarantees of origin ensure that as much green power from renewable energies is fed into the grid as is withdrawn via Mercedes me Charge. In the first two years after the purchase of an EQS, there is no basic charge for Mercedes me Charge and thus Green Charging for customers. With the new Plug & Charge function, the EQS can also be charged particularly conveniently.

Mercedes me Charge currently has access to the largest charging network worldwide: It currently has more than 500,000 AC and DC charging points in 31 countries, including over 200,000 in Europe and over 90% coverage of public charging points in the USA. In addition, the functionality of Mercedes me Charge in MBUX will be expanded to include functions such as filtering and forecasting the availability of charging stations.

How Green Charging works: To promote the use of electricity from renewable energies, Mercedes-Benz uses guarantees of origin to 'green' the charging process, whose quality is defined by an eco power label. This ensures that an equivalent amount of electricity from renewable resources is fed into the grid to compensate for the charging of an electric vehicle. Amounts of energy used for charging are thus offset with green power after the actual charging process, also creating incentives to invest in renewable energy plants. In the first two years after the purchase of an EQS, there is no basic charge for Mercedes me Charge and thus Green Charging for customers. The prices of the charging operator may vary. Green charging and driving become tangible with MBUX.

Plug & Charge - simpler and more convenient charging
The new Mercedes me Charge function Plug & Charge makes it even easier to charge the EQS at suitable public charging stations: charging starts as soon as the charging cable is plugged in; no further authentication on the part of the customer is required. The vehicle and the charging station communicate directly via the charging cable.

Additionally, Mercedes me Charge customers continue to benefit from the integrated payment function with automatic payment. The customer chooses the preferred payment method only once. Every charging process is then automatically debited. The individual charging processes are clearly listed in a monthly invoice.

Whether a charging station is Plug & Charge-capable can be seen via the display of the charging station details on the head unit of the EQS and the Mercedes me App. It is also possible to search for specific, suitable charging stations. Plug & Charge is the fourth way to access charging points, alongside enabling via MBUX on the vehicle's media display, the Mercedes me App and the Mercedes me Charge card.

Mercedes me App: easy operation on smartphone and tablet
The Mercedes me App offers many improved and new functions since the last revision. These include a filter option that allows the charging points to be sorted according to criteria such as availability or charging capacity. The likelihood over the course of the day of a particular charging point being busy is also determined and displayed on the basis of a probability calculation.

Always connected

The new EQS: the charging functions

Three charging programs are offered in the EQS - Standard, Home and Work. In these, parameters such as departure time, air conditioning and maximum charge level can be preset. The Home and Work charging programs can be activated based on location. This means that they are switched on automatically as soon as the vehicle is parked at a charging point at the positions stored in the system. The user is informed about this in MBUX.

The EQS also has these intelligent charging functions:

  • ECO Charging is a take-it-easy program for the battery. Various measures reduce the battery load during charging and slow down the natural ageing process of the battery. For example, the maximum charging capacity is reduced, a charging limit of 80 percent is observed and charging is delayed based on the set departure time.
  • With the charging interruptions function, the customer can specify time periods during which the AC charging processes are paused. Electricity costs can be saved as a result, for example.

The charging components of the EQS
A latest-generation charging system sits above the rear axle of the EQS. It can be used to charge the battery via the public power grid with single-phase or three-phase alternating current and a charging capacity of up to 9.6 kW. In addition, intelligent wallboxes from national partners are available to customers in the individual markets.

A DC box with a charging capacity of up to 200 kW is fitted on board for (fast) charging via direct current. High charging currents can be maintained for a long time through temperature and charging management. Power for up to another 300 kilometers (WLTP) is recharged in just 15 minutes1.

The actual charging time depends on the battery size, the available infrastructure and the country-specific vehicle equipment. The charging socket is located at the rear right of the vehicle and is designed according to market requirements:

  • Europe and the USA will receive the CCS system (Combined Charging System), which allows charging with direct and alternating current via the same connection.

With the new Plug & Charge function, Mercedes me Charge customers can charge the EQS conveniently.

Because the shortest route is not always the fastest

The new EQS: navigation with Electric Intelligence

As far as Navigation with Electric Intelligence is concerned, the name says it all. The system plans the fastest and most convenient route, including charging stops, based on numerous factors and reacts dynamically to traffic jams or a change in driving style, for example. In the EQS, Navigation with Electric Intelligence is smarter than ever: this is how the estimated charging costs per charging stop are calculated. Furthermore, the customer can edit the planned routes individually by adding in preferred charging stations along the route or excluding proposed charging stations.

While a conventional range calculator utilizes past data, the Navigation with Electric Intelligence system looks into the future. The energy demand is computed for the calculation of the route. The topography, route, ambient temperature, speed, heating and cooling requirements are all taken into account. Further factors include the traffic situation along the planned route, as well as the available charging stations that can be found there, their capacity and payment functions. Calculation takes place in the Cloud and is combined with on-board data.

The customer does not necessarily always need to take on a full charge, but will be given a specific recommendation as to the required charging time at the charging station. The charging station stops will be planned in the way that is most favorable for the overall traveling time: Under certain circumstances, two short charging stops with a higher charging power can be more advantageous than charging once for a long time. In addition, Electric Intelligence navigation automatically adjusts the vehicle's charging settings and optimizes them for fast charging along the route.

A new feature of the EQS is a visualization in MBUX of whether the available battery capacity is sufficient to return to the starting point without charging. Charging stations along the route that have been added manually are given preference in the route calculation. Proposed charging stations can be excluded. The estimated charging costs per charging stop are also calculated.

If there is a risk of not reaching the destination or the charging station with the set settings, Active Range Monitoring issues the prompt to activate ECO driving functions. In addition, the driving speed for reaching the next charging station or the destination is calculated and displayed in the speedometer. Under the menu item "Range", the EQS driver can switch off various energy consumers to increase the range and activate the ECO driving functions to support a more efficient driving style.

Activating new functions after buying a new car

The new EQS: Over-the-Air-Updates (OTA)

The EQS is the first Mercedes-Benz to offer the option of activating completely new vehicle functions via over-the-air updates (OTA) in a number of functional areas. Available from launch: two special driving programs for drivers, games and the demo program "The best or nothing". This means that, following the purchase and the initial new-car configuration, some of the features of the EQS can be adapted according to personal preferences. This also includes the release of the rear-axle steering with a ten-degree steering angle. In addition to the classic purchase of individual functions, subscriptions, temporary activations and free test phases are also planned.

Updates overnight and new functions the next morning, just like on a smartphone - the OTA technology in the EQS makes it possible. The explicit consent of the user is always a precondition for OTA updates. Mercedes- Benz relies on mobile radio technology and the communication module installed in the vehicle because of the high security standard. This is how OTA in the EQS works in detail:

The following OTA features are available at the launch of the EQS:
The additional driving sound "Roaring Pulse" is available in the Mercedes me Store. This extroverted sound is reminiscent of powerful elements such as large-volume combustion engines, turbines and the forces of nature. There will also be small entertaining games such as a number puzzle or a Mercedes-Benz quiz. You can even play games with each other on the front passenger display and the tablet in the rear in multi-player mode.

"The best or nothing" program can also be activated via OTA. There the EQS introduces itself. The various vehicle functions are shown in a video, and special features such as ambient lighting or seat massage can be experienced directly.

With two standard digital security functions, the use of the EQS can be adapted to specific target groups:

  • In beginner driver mode, the driving characteristics are deliberately gentler. Nevertheless, sufficient power reserves are available for overtaking. Driving mode C is automatically activated, while driving mode Sport is disabled. The top speed is limited to approx. 75 mph, ESP-OFF cannot be activated.
  • The valet mode is intended for use by service personnel such as hotel staff. The characteristics are similar to the beginner driver mode. A maximum of approx. 50 mph is possible and the personal profile data is protected against unauthorized access.

The main user activates and deactivates these programs via their personal profile, which is protected with a PIN and/or biometric recognition, or conveniently via the Mercedes me App from the smartphone. The modes can only be activated with a restart.

Independently of these new functions, it is also possible to update the majority of the control units in the vehicle OTA for service and maintenance purposes. This technology saves the customer time, as they do not need to visit a workshop for this purpose. Furthermore, many functions of their vehicle remain up to date throughout its lifetime.

Consistent digitization and borrowings from interior design

The new EQS: the interior design

The EQS is the luxurious and avant-garde top-of-the-range model from Mercedes-EQ. With this completely new type of vehicle, the designers had the mission and the opportunity to take a completely new approach to the interior design as well. They made use of this freedom, and in addition to the MBUX Hyperscreen, relied on consistent digitization for many other elements.

The EQS is the first Mercedes-EQ to be based on an all-electric platform. For the designers, this went hand in hand with the vision of consistent digitization of the interior. The optional MBUX Hyperscreen impressively implements this vision: the entire instrument panel is one ultimate widescreen. This determines the aesthetics of the entire cockpit and interior. The real glass appears to drape itself in three dimensions over the entire width of the vehicle like a wave - a unique feature in automotive construction to date.

The high-resolution screens appear to merge seamlessly under the shared glass cover. The graphic appearance of their MBUX content is tailored to each other. The MBUX Hyperscreen is integrated into the instrument panel in minimalist fashion. The MBUX Hyperscreen is surrounded only by a thin silver shadow frame, a vent band and a narrow frame, similar to the lower volume body of classic instrument panels.

The vent band with rose gold accents spans across the entire width at the top and is very slim at the same time. These extreme proportions, together with the glass wave of the MBUX Hyperscreen, create the avant- garde architecture of the cockpit.

The dominant outer vents are inspired by jet turbines. They deliberately play on the theme of hyperanalogue through the contrast between high-tech precision mechanics and a digital, glass display world. The intricately designed turbine blades distribute the airflow efficiently.

The front section of the center console joins the instrument panel and stands freely in space. It is a visual reference to the new drive architecture - due to the electric powertrain, no transmission tunnel is necessary. Flowing leather surfaces with intricate seam patterns create a lot of storage space in combination with a large cover made of real wood. The visual impression is both modern and luxurious.

The base model without MBUX Hyperscreen has a slightly different center console. There is a soft armrest in the rear section. It is first visually interrupted before being transitioned into the floating central display.

The design of the door panels borrows from the interior design of modern living spaces. Doors and their center panels emerge from behind the MBUX Hyperscreen to span the space. A surface-mounted modular body floats like a sideboard in front of the door panel. It accommodates all necessary door elements such as armrest, door module, pull handle and side door pocket. Circular ambient lighting completes this floating, avant-garde aesthetic in the dark.

The standard interior of the EQS includes the comfort seats. Despite their simplicity of design, they captivate with their sculptural beauty. Wrap-around surfaces in the side bolsters create the body support and stand in stark contrast to the seat center panel. It has a sophisticated seam pattern similar to a fan palm.

In combination with the AMG Line interior, the EQS is fitted with the sports seats. They are characterized by a slim and monolithic shape. The seat surfaces are designed in such a way that they give the impression of draped-on leather blankets. The technical term is "layering".

Common features of the seats are the dynamic graphic patterns with highly elaborate, positioned perforations. Here, too, you will find the hallmark Mercedes-EQ combination of the highest standards in materials, ambience and workmanship as well as state-of-the-art technology.

Color & trim: avant-garde and tradition for a special ambience
Avant-garde as well as traditional materials and colors give the interior a special atmosphere.

The modern delicate structure NEOTEX combines the look of nubuck leather and high-tech neoprene. NEOTEX is found on the instrument panel and the armrests.

Eight coordinated color combinations in the interior emphasize the generous feeling of space. The EQS is immersed in a progressive and luxurious color world of warm and cool tones. Colors such as Sable Brown/ Neva Grey and Space Grey/Macchiato Beige add the finishing touches to the soft and emotive design. The color rose gold, derived and evolved from the electric coil, emphasizes the design of the vent band and is used as a contrasting color.

The shape of both seats is outlined by illuminated piping. This creates a unique night-time ambience. The innovative trim elements make a decisive contribution to the aesthetics in the EQS. Two examples: the anthracite 3D relief-look trim elements feature tiny metal pigments. The different lighting situations in the vehicle subtly change the appearance and create a subtle value appeal.

Laser-cut trim elements backlit with a Mercedes-Benz Star pattern 1also create a special ambience. The star pattern is lasered into the plastic trim and is adaptively backlit. Wood trim elements are also available, for example, Anthracite Natural Grain Linden Wood or Natural Grain Brown Walnut Wood with Aluminum Lines – which is inspired by the deck of a luxury yacht..

A special welcome & goodbye scenario2 has been developed for the Mercedes-EQ models, which is also coordinated with the ambient lighting.

UX design: multiple display styles and modes to choose from
The functional content and operating structure corresponding to the S-Class have been adapted to electric driving. Visually, all graphics are designed in a new color world of blue/orange throughout. The classic cockpit display of the two round dials has been reinterpreted, giving it the optic of a digital laser sword in a glass lens. All content relevant to driving can be accessed between the round dials in the driver’s display.

The "sporty" display from the S-Class has been converted into a three-dimensional performance bar and emotively and impressively conveys the respective driving status (Drive, Accelerate, Charge). The central object here is a "G-force puck", which dynamically moves freely in space in line with the acceleration forces.

The appearance of the screens can be individualized with three display styles (understanded, sport, classic) and three modes (Navigation, Assistance, Service).

For a very calm interior impression, the understated mode familiar from the S-Class has been adapted. In the EQS, the content of the displays is reduced as much as possible and coordinated with the color change of the ambient lighting in seven screen color worlds. In "Assistance" mode, important events such as lane changes or target distance control, as well as the infrastructure and detected other road users (cars, motorcycles, trucks) are displayed.

Head-up displays are available in two sizes. They contribute to relaxed driving, as the driver does not need to look away from the road. The large augmented head-up display is the highlight here, as it shows relevant information and actions three-dimensionally in the actual driving situation and environment.

”The MBUX Hyperscreen is both the brain and nervous system of the car”

The new EQS: Double interview on MBUX (Mercedes-Benz User Experience) with

Gorden Wagener, Chief Design Officer Daimler Group, and Sajjad Khan, Member of the Board of Management of Mercedes-Benz AG and CTO, about the new MBUX Generation.

Mr. Wagener, the new MBUX Generation candomore, knows more and says more: When was the last time you said "Hey Mercedes!"? And if you don't mind me asking, what did you ask the voice assistant?

Wagener: It was just 15 minutes ago on the way into the office. When I use MBUX, it's intuitive, I don't have to think about if and how. That is in fact how my parents' generation thinks: would I like to use the technology? Today, it is totally different, the fusion of technology and design makes it so easy: I want to use this technology. If technology can do a lot of things, but I have to work to use it then I’m less inclined. Our success is based on the idea that it must work just as brilliantly as it looks. And I asked Hey Mercedes to stop the music as I wanted to enjoy the quietness of the electric drive - I was in my E-Class with plug-in hybrid.

You presented the first MBUX generation in January 2018 at CES in Las Vegas. How was it as an automotive manufacturer ata trade fair for entertainment electronics to present the vehicle cockpit of the future?

Khan: The days of the world premiere of MBUX in Las Vegas were really exciting for my team and I. Would we have the comprehensive programming ready in time? Would everything in the seat boxes work at the live demo? And would the journalists realize the potential of MBUX? Well we had the luck of those who work hard: everything worked wonderfully, and the media representatives and the public were enthusiastic. Just four months later, the new A-Class came to market as the first model with MBUX. There are now more than 1.8 million Mercedes-Benz passenger cars on the roads with it around the world, and it is also available in the Van division. A new Mercedes without MBUX is now inconceivable. We are now linking in to this great success story with the second MBUX Generation.

Wagener: The trade show in Las Vegas was just the right place for the world premiere of MBUX: Although the abbreviation CES stands for Consumer Electronics Show, CES has developed into an important technology trade show. This reflects the increasing digitization and networking of all areas of life. Just like seismographs detecting earthquakes around the world, my design colleagues in our four international design studios sense exactly these trends and are inspired by new ideas from different continents and cultures; their field of work is the future. Visiting CES has always been a source of great inspiration, especially where user experience or trends such as fit and healthy are concerned.

With the large head-up display with augmented reality content such asanimated turn arrows andbiometric authentication, MBUXhasnow taken another bigstep towards digitizationand artificialintelligence. And you could evensay that with the MBUX Hyperscreen the huge television has found its way into the car. What are the highlights of the new MBUX Generation for you?

Khan: Of course I have my favorites, and the huge MBUX Hyperscreen in the EQS is one of them. With its unique electric aesthetics and the high level of user friendliness, the hyperscreen is representative of the overall character of the EQS – avant-garde, cool, personal and useful. But it's important for me to not just talk about the individual hardware components of MBUX. The clever networking of all systems and the intelligent software that is capable of learning are also decisive. Our MBUX philosophy is to offer our customers maximum comfort, personalization and convenience. A system that goes into even more detail, is more well thought-out and more individualized than ever before. The advantage for our customers: Thanks to further improved user-friendliness, they save time and receive a high added value. MBUX is thus the backbone or even the brain of the vehicle.

Wagener: Our goal for MBUX was to create the most coveted infotainment system in a car. We transferred the bipolarity of our design philosophy of Sensual Purity to MBUX - that means on one hand the sensual beauty and on the other the “Wow effect” of the unique intuitive operation. And with the EQS as the representative of Progressive Luxury we could be somewhat more modern, more courageous and more polarizing. This also applied to the exterior, just as a side note. I agree with Sajjad, the MBUX Hyperscreen is also my absolute favorite in the interior – a digital work of art, a futuristic, luxurious sculpture and also a powerful technological challenge.

But digital beauty is only oneaspect of MBUX, right? To what extent was the excellent user friendliness of MBUX increased even further?

Wagener: We stage technology through design in a way that is fun and at the same time really beautiful, and intuitive. Because alongside the cool hardware, the content is equally important, i.e. what we display on the screen unit. Visually inspiring with super fine details. And our Zero Layer is another element that makes operation even easier, where the most important and most frequently used interactions can be operated on one single level, the top level. You rarely have to delve into sub-menus and this shortens interaction times. This is a continuation of the intuitive operation and belongs to the emotional intelligence of our brand Mercedes-EQ.

Khan: Yes, the MBUX Hyperscreen is both the brain and nervous system of the car, it is connected to all components of the vehicle and communicates with them. This makes a new form of interactivity and individuality possible. Because the customer is at the center of development. We analyzed the customer feedback from the first MBUX Generation and asked ourselves: 'What do people need and how do they interact with the car? Especially in an electric car?' The goal was to come up with a concept that does not distract the driver or require complicated operation. And it has to be capable of learning thanks to artificial intelligence: The MBUX Hyperscreen continually gets to know the customer better and in this way delivers a tailored, personalized infotainment and operating offering before the occupant even has to click anywhere. It was not our aim to create the biggest screen of all time in a car. Rather, we developed special screens with the perfect ratio of size to functionality for the best possible level of user friendliness. That is customer orientation and digital thinking for 2021!

Zero-layer design: the most important thing is now only one click away

The new EQS: MBUX (Mercedes-Benz User Experience)

MBUX (Mercedes-Benz User Experience) has radically simplified the operation of a Mercedes-Benz. Introduced in 2018 in the current A-Class, more than 1.8 million Mercedes-Benz passenger cars are now on the road with it, and the Vans division is also utilizing MBUX. A few months ago the second generation of this learn-capable system debuted in the new S-Class. The new EQS is already taking the next big step.

With learn-capable software, the control and display concept completely adapts to its user and makes personalized suggestions for numerous infotainment, comfort and vehicle functions. With the zero-layer concept, the user does not need to scroll through submenus or give voice commands. The key applications are always offered on the top level in the field of vision, depending on the situation and context. This means that numerous operating steps are already taken care of for the EQS driver. Mercedes-Benz has integrated numerous music streaming providers holistically into the MBUX Infotainment system with the "Online Music" service.

Infotainment systems offer numerous and extensive functions. Several operating steps are often required to control them. In order to reduce these interactive steps even further, with the aid of artificial intelligence Mercedes-Benz has developed a user interface with context-sensitive awareness.

The MBUX system proactively displays the right functions at the right time for the user, supported by artificial intelligence. The context-sensitive awareness is constantly optimized, both reacting to changes in the surroundings and user behavior. The zero layer offers the user dynamic, aggregated content from the entire MBUX system, and thus the associated services, on the uppermost level of the MBUX information architecture.

Mercedes-Benz has investigated the usage behavior of the first MBUX generation and found most of the use cases fall in the Navigation, Radio/Media and Telephone categories. The navigation application with its full range of functions is therefore always in the center of the visual display unit.

Over 20 other functions - from ENERGIZING COMFORT to birthday reminders and suggestions for the to-do list - are automatically offered with the help of artificial intelligence when they are relevant to the customer. The developers have internally named these suggestion modules, which are displayed on the zero-layer interface, "Magic Modules".

Here are five representative use cases. The user can accept or reject the respective suggestion with just one click:

  • When approaching a charging station that is enabled for Plug & Charge, the Magic Module 'Charging' automatically appears. The driver can then start charging immediately.
  • If someone always calls one particular friend on the way home on Tuesday evenings, in future they will always receive a suggestion regarding this particular call on this day of the week and at this time. A business card appears with their contact information and – if this is stored – their photo. All the suggestions from MBUX are coupled with the logged-in profile of the user. So if someone else drives the EQS on a Tuesday evening, with their own profile logged-in, this recommendation is not displayed.
  • If the EQS driver regularly uses the Hot Stone Massage function, the system automatically suggests the comfort function to them in colder temperatures.
  • If the user regularly switches on the heating of the steering wheel in addition to the seat heating, for example, this is suggested to them as soon as they activate the seat heating.
  • The EQS's chassis can be raised in order to offer more ground clearance. A useful function for steep driveways or speedbumps. MBUX remembers the GPS position at which the user has selected the "Raise Vehicle" function. If the vehicle approaches this GPS position again, MBUX suggests raising of the EQS.

MBUX: a milestone as the interface between driver, passengers and vehicle
The EQS features the current MBUX generation, which celebrated its premiere in the new S-Class only a few months ago. As standard, the new model is equipped with a 12.3-inch driver display and a 12.8-inch central display in portrait orientation. The impressive MBUX Hyperscreen is available as an option. With this, the front passenger also has his or her own screen.

Face recognition with cameras in the driver display is used for a wide range of assistance and comfort functions. These include biometric authentication, ATTENTION ASSIST fatigue warning and adjusting the exterior mirrors to the pre-set position. Also on board as standard: a fingerprint scanner for driver authentication.

Hey Mercedes: the voice assistant can now do even more
Compared with the previous MBUX generation, the "Hey Mercedes" voice assistant is even more capable of dialogue and learning by activating online services in the Mercedes me App. Moreover, certain actions can be performed even without the activation keyword "Hey Mercedes". These include accepting a phone call. "Hey Mercedes" now also explains vehicle functions, and can help for example when asked how to connect a smartphone by Bluetooth. "Hey Mercedes" is now also able to recognize vehicle occupants by their voices.

Once the individual characteristics of the voice have been learned, this can be used to access personal data and functions by activating a profile.

The voice assistant in the EQS can also be operated from the rear. In general, rear passengers experience the same comprehensive infotainment and comfort offerings as the driver and front passenger.

Rear Seat: comfort like in the front row
Screen content can be quickly and easily shared with other passengers. Selection and amendment of navigation destinations is possible from the rear seats. The MBUX rear tablet is optionally available, as a fully- fledged tablet, this can also be used outside the vehicle and (Android) apps can be installed. With this convenient remote control, all rear seat functions can be comfortably controlled from any seating position.

Online music: music streaming with millions of songs to choose from
Mercedes-Benz has integrated many music streaming providers completely into the MBUX infotainment system with the "Online Music" service. MBUX enables access to the personal user profile at the linked music providers. This allows customers to seamlessly access their favorite songs and playlists and discover millions of songs as well as curated playlists. Operation is intuitive using the MBUX voice assistant via "Hey Mercedes" and via touch controls on the steering wheel or central display.

Personalization is simple and convenient
A personal profile can be created directly in the EQS and synchronized with the existing profile data of the Mercedes me account. By scanning a QR code with the Mercedes me App, the vehicle is automatically connected to the Mercedes me account.

Personal preferences such as a favorite radio station and preselected settings can be transferred to any seat via the personal Mercedes me profile. Up to seven different profiles with a total of around 800 parameters are possible in the vehicle. The ambient lighting can be individually set by remote configuration, i.e. from home.

As the profiles are stored in the Cloud as part of Mercedes me, the profiles can also be used in other Mercedes-Benz vehicles with the new MBUX generation.

In addition to the classic entry of a PIN, a special authentication procedure ensures a high level of security. Fingerprint, face and voice recognition are combined. This allows access to individual settings or verification of digital payment processes from the vehicle.

Welcome to the big in-car show

The new EQS: the MBUX Hyperscreen

The MBUX Hyperscreen is the absolute highlight in the interior. This large, curved screen unit sweeps almost from A-pillar to A-pillar. Three screens sit under a common bonded glass cover and visually merge into one display. In addition to the zero-layer design, the MBUX Hyperscreen offers intuitive touch operation with haptic feedback and force feedback. The scratch-resistant glass is coated to make cleaning easier.

With the MBUX Hyperscreen (standard on EQS 580), three displays merge almost seamlessly into one another to create an impressive screen band over 56 inches wide: The Driver display (screen diagonal: 12.3 inch), central display (17.7 inch) and front passenger display (12.3 inch) appear as one visual unit.

The selected display style is shown uniformly on all screens; and the brightness is homogeneously adapted to the lighting conditions in the interior. The control panels for the automatic climate control system are located in the lower area of the central display. These remain permanently displayed so that the driver and front passenger can feasibly adjust the temperature and ventilation.

For particularly brilliant display quality OLED technology is used for the central and front passenger displays. This is where the individual image points are self-luminous; non-controlled image pixels remain switched off, which means that they appear deep black. The active OLED pixels, on the other hand, shine with a high color brilliance, which also means high contrast values – irrespective of the perspective and the light conditions.

The central and front passenger displays also provide haptic feedback. When a finger touches certain spots on the touch screen, actuators (eight in the central display, four in the front passenger display) trigger a perceptible vibration of the cover glass. The user thus feels pulses on the smooth surface, which gives the impression of a mechanical switch. Another operating aid known from high-quality consumer electronics products is the force feedback of both displays. For this purpose, a metallized foam is integrated into the device as a force sensor. Different levels of pressure on the glass change the response. For example, with added pressure MBUX then jumps to another menu level.

The 12.3-inch OLED display for the front passenger gives them their own display and control area, making journeys more enjoyable and entertaining. However, the entertainment functions of the front passenger's display are only available within the framework of the national legal regulations during the journey. Mercedes relies on an intelligent, camera-based locking logic: if the camera detects that the driver is looking in the direction of the front passenger display, it is automatically dimmed when certain content is displayed. Resulting in the driver not being able to look at them while driving. If the front passenger seat is not occupied, the screen becomes a digital decorative image. The customer can choose from various decorative images, including a starry sky or the Mercedes-Benz Star pattern.

The curved cover glass is made of particularly scratch-resistant aluminum silicate glass and is coated to make cleaning easier. For example, fingerprint marks can be easily removed with a microfiber cloth.

Ergonomic, sophisticated, robust: the development
During the development of the MBUX Hyperscreen, Mercedes-Benz engineers carried out extensive ergonomics studies. The result is an optimized alignment of the MBUX Hyperscreen to reduce reflections caused by the curvature of the cover glass. In addition, the upper part of the windscreen is shaded by a tinted strip.

Other details designed with the hallmark Mercedes-Benz meticulousness include the brightness of all three screens, which is adjusted to the respective ambient conditions. A light sensor above the central display is used to determine the illumination level in the driver and front passenger areas. In addition, the camera integrated in the driver display measures the ambient brightness. Both the brightness and the image content of the displays are then adjusted. At the same time, this algorithm is less susceptible to scattered light and thus to misinterpretation of the measurement system.

Tolerance to high temperature differences, immunity to vibrations and protection against dust are among the tough automotive requirements for which the entire system has been designed. Age-related burn-in effects of OLED displays are countered with the help of various technical solutions. The ageing process of each individual pixel is permanently monitored and an automatic adjustment is carried out in the background to compensate for it. In addition, the displayed image information rotates slightly and imperceptibly counter- clockwise to reduce permanent strain.

Curved, bonded and printed: the production
The large cover glass is curved three-dimensionally using the molding process. This hot forming of glass at process temperatures of approx. 1202°F places the highest demands on mold making and process control and is used in the production of optical glass for camera lenses and smartphone cover glasses. With the MBUX Hyperscreen, this process enables a distortion-free view of the displays across the entire width of the vehicle, regardless of the radius of the cover glass.

All displays are transparently bonded to the cover glass for a uniform refractive index curve to avoid reflections as much as possible. The central and front passenger displays are optically connected to the cover glass under a vacuum. This dry bonding process uses an adhesive material similar to double-sided adhesive tape. The LCD driver display, which is flat due to its design, uses a wet bonding process in which the adhesive material is liquid to compensate for the radius of the cover glass.

The black areas between the screens are printed onto the cover glass from behind using a screen printing process specially adapted to the curvature. The color of the black print was adapted to the reflection behavior of the OLED displays in order to achieve a homogeneous overall impression in a wide variety of lighting situations. For certain important warning lights to the right and left of the driver display, a mask is used during the screen printing process to leave out the corresponding symbol.

The MBUX Hyperscreen is surrounded by a continuous front frame in plastic. This visible part is painted in "Silver Shadow" using an extensive three-coating process. This paint system achieves an especially high- quality surface impression through extremely thin intermediate coats. The integrated ambient lighting included in the lower section of the MBUX Hyperscreen appears to make the display unit hover on the instrument panel.

Extensive precautions: the safety measures
The MBUX Hyperscreen is bolted directly to the cockpit cross-member for stability: The connection to a stabilizing magnesium support as the structural component of the MBUX Hyperscreen is made via aluminum brackets. Their honeycomb structure allows them to deform in a controlled manner in a crash. For side impact protection, the cover glass also does not extend all the way to the doors. In the event of a severe side impact, there are also predetermined breaking points behind the side air vents.

Between comfortable tranquility and an interactive, sensuous sound experience

The new EQS: the Sound Experiences

Electric cars are inherently quiet. If desired, the ride in the EQS nevertheless becomes an acoustic experience: With a holistic sound production, the sound experts from Mercedes have made the paradigm shift from the combustion engine to the electric car acoustically perceptible. An optional interior driving sound is available. It adjusts adaptively to the driving style and drive program.

A variety of soundscapes allows for an individual acoustic set-up. With the standard Burmester® surround sound system, the EQS comes with two soundscapes: Silver Waves and Vivid Flux. Silver Waves provides a rich and clean sound. Aimed at EV enthusiasts, Vivid Flux is crystalline, synthetic yet humanly warm. They can be selected or switched off as sound experiences on the central display. Another soundscape, Roaring Pulse, can be unlocked using over-the-air technology. This sound experience is reminiscent of powerful machines, and is sonorous and extroverted.

Driver and passengers are greeted with a welcome sound when approaching the vehicle and when getting in. A corresponding aura sound also accompanies exiting and locking the EQS. Also part of the particular soundscape is the driving sound, which is reproduced by the speakers in the interior, it stirs emotions and inspires. At the same time, the driving sound is interactive, as it responds to over a dozen parameters such as the accelerator position, speed or recuperation. The choice of drive program also influences the driving sound; in SPORT mode, for example, the sounds become more dynamic and further effects areactivated.

Intelligent sound design algorithms calculate the sounds inside the amplifier of the Burmester® surround sound system in real time, and the loudspeakers reproduce them.

The algorithms and sounds for the sound design are created internally at Mercedes-EQ. In addition to physicists, the interdisciplinary team also includes sound designers, media designers and mechatronics specialists. In the acoustics laboratory, which is completely shielded from external noise and vibrations, they work on the sound of the EQS and its model siblings. The sound experts determine which emotions the soundscapes evoke in real traffic during test drives. The mobile listening tests take place with interactive demonstrator vehicles, including at the new Immendingen Test and Technology Centre (PTZ).

In order to achieve an interplay between the driver's action, the vehicle's reaction and the feedback of the sound, musical composition such as harmony theory is not the only foundation. The liveliness of the soundscape varies as the result of many sound dimensions. In this way, the sound design creates a holistic, multi-sensory experience that interacts with the entire vehicle. This experience is in the conflicting area between comfortable quiet and precise feedback with emotionally appealing design.

Quick learner thanks to AI

The new EQS: Artificial intelligence (AI)

But the EQS is not only a car that appeals to (almost) all human senses. As an exceptionally intelligent vehicle, it also has many senses itself. Depending on the equipment, up to 350 sensors of various types are used as sensory organs in all parts of the car. They record distances, speeds and accelerations, lighting conditions, precipitation and temperatures, the occupancy of seats as well as the driver's blink of an eye or the passengers' speech.

This wealth of information is processed by control units that, controlled by algorithms, make decisions at lightning speed. They are the brain, so to speak, but a lot of information is only useful if you can do something with it. The new EQS can expand its capabilities based on new experiences, because it is highly capable of learning thanks to artificial intelligence (AI).

Here are some examples of how and where AI is improving the customer experience:

  • The optional driving sound is interactive, reacting to a good dozen different parameters such as the position of the accelerator pedal, speed or recuperation. The choice of drive program also influences the driving sound. Intelligent sound design algorithms calculate the sounds in the amplifier of the Burmester® surround sound system in real time, and the loudspeakers reproduce them.
  • The ENERGIZING COACH recommends one of the ENERGIZING COMFORT programs Freshness, Warmth, Vitality or Joy depending on the situation and the individual. If the Mercedes-Benz vivoactive® 3 smartwatch, the Mercedes-Benz Venu® smartwatch or another compatible Garmin® wearable is linked, personal values such as stress level or sleep quality optimize the precision of the recommendation.
  • The MBUX system proactively shows the right functions for the user at the right time. The context- sensitive awareness is constantly optimized, both by changes in the surroundings and by user behavior. The zero layer offers the user dynamic, aggregated content from the entire MBUX system, and thus the associated services, on the uppermost level of the MBUX information architecture.

HEPA filter against airborne pollutants

The new EQS: ENERGIZING AIR CONTROL Plus

Keeping fine dust, microparticles, pollen and other substances outside. This is because its HEPA filter (High Efficiency Particulate Air) cleans the incoming outside air at a very high filtration level. In recirculation mode, the air is filtered by the interior air filter of the automatic climate control system. Sulphur dioxide and nitrogen oxides as well as odors are also reduced thanks to the activated charcoal coating on the HEPA filter and the interior air filter. The HEPA filter is part of the optional equipment ENERGIZING AIR CONTROL Plus and uses the space under the front hood of the EQS. It carries the "OFI CERT" ZG 250-1 certification in the area of viruses and bacteria protection.

The system is based on filtration, sensors, a display concept and air conditioning. In combination with the intelligent fresh air/recirculating air switching, ENERGIZING AIR CONTROL Plus ensures good air in the vehicle interior. The particulate levels are also displayed in real time in MBUX. Using pre-entry climate control, it is also possible to clean the interior air before getting into the vehicle.

Thanks to its purpose design, the EQS accommodates a large filter system under the front hood. The HEPA Filter’s dimensions are 23”/16”/1.6” and its volume is almost three gallons. Filtration takes place in three stages. A coarse pre-filter retains leaves, snow and sand and traps larger particles. At the same time, it protects the HEPA filter from a high concentration of coarse particles. The separation in this HEPA (High Efficiency Particulate Air) filter uses a mechanical process by means of a synthetic membrane: The microfiber layer traps fine dust of the class PM 2.5 to PM 0.3 - these particles are therefore smaller than 2.5 μm. Over 99.65 percent of particles of all sizes are removed according to the filter's efficiency certified pursuant to DIN EN 1822. The reduction of pollutants achieved at the filter is comparable to that in clean rooms and operating rooms.

In the third and final step, further fine particles as well as sulphur dioxide, nitrogen oxides and unpleasant odors are filtered out. The filtration of sulphur dioxide and nitrogen oxides is carried out by special activated charcoals in the HEPA filter and the interior air filter. Due to their pore structure, they have a very large inner surface area. Around 600 grams of activated charcoal are used in the HEPA filter of the EQS. The adsorption area is equivalent to about 150 football fields. Activated charcoal is produced from coconut shells, which are a by-product of the cosmetics industry.

Mercedes-Benz was the first automotive manufacturer to receive the "OFI CERT" ZG 250-1 certification from the Austrian Research and Testing Institute (OFI). Air filters with this certificate reduce bacteria and viruses directly at the filter. To prove their quality, the air filters must pass standardized tests and are checked using additional scientific analyzes. The test results certify that ENERGIZING AIR CONTROL Plus has

  • A virus capturing capacity of more than 86 percent in new condition
  • A virus capturing capacity of more than 80 percent in aged condition after climate change test with different temperatures and humidity levels
  • A bacteria capturing capacity of more than 90 percent in new condition
  • A bacteria capturing capacity of more than 88 percent in aged condition after climate change test
  • A very low re-shedding of filtered viruses on the back of the filter below the infection threshold

Always informed: indication of fine dust values outside and inside the vehicle
Combined with the automatic fresh air/recirculating air mode, ENERGIZING AIR CONTROL Plus ensures good air quality inside the vehicle. The air-conditioned recirculated air is filtered several times in recirculation mode, and flushing with fresh air takes place at regular intervals. Using pre-entry climate control, it is also possible to clean the interior air before getting into the vehicle.

The particulate levels outside and inside the vehicle are also displayed in MBUX. They can be viewed in detail in the dedicated Air Quality menu. If the quality of the outside air is low, the system can also recommend closing the side windows or the sliding sunroof.

No.6 MOOD Linen: fig meets linen
The active fragrance of the EQS, which is part of the AIR-BALANCE Package, also appeals to the sense of smell. A special fragrance was composed for the new electric top-of-the-range model: No.6 MOOD Linen. Fig provides a green note for this fragrance, which is rounded off with linen. It gives the slight impression of a fig tree standing at a high elevation and surrounded by fresh, cool air.

The new nomenclature of the Mercedes fragrances is composed of an iconic number of the respective brand, the designation "MOOD" and the main ingredient of the fragrance. The Mercedes-EQ fragrances bear the number 6, as the first electric cars were added to the model range in 1906 with the "Mercédès Electrique" vehicles. Their electric wheel hub motors were powered by a battery. They were available as passenger cars, trucks, buses, ambulances and fire engines in a wide variety of designs.

Acoustic oasis with summer rain, seagull sounds and rustling leaves

The new EQS: ENERGIZING COMFORT

ENERGIZING COMFORT reaches the next level in the EQS: the three ENERGIZING NATURE programs Forest Glade, Sounds of the Sea and Summer Rain, are also new. These provide an immersive and impressively realistic on-board sound experience. These calming sounds were created in consultation with the acoustic ecologist Gordon Hempton. As with the other ENERGIZING COMFORT programs, other senses are addressed with lighting moods and images. A new feature of the short sleep program during a break is the expanded conditioning of the interior: It closes the roller blind of the panoramic sliding sunroof and moves the driver's seat into the rest position. This creates an atmosphere that is conducive to sleeping.

The power nap can increase the driver's performance and give him/her new energy.

The new ENERGIZING NATURE programs at a glance:

  • Forest Glade: can help to escape the noisy daily routine and boost concentration. Birdsong, rustling leaves and a gentle breeze create a feel-good ambience. The program is rounded off by warm music soundscapes and subtle fragrance.
  • Sounds of the Sea: can have a positive and relaxing effect through the combination of soft music soundscapes, wave sounds and seagull sounds. Warms and cools at the same time with the soothingly slow rhythm of the ocean waves combined with blasts of air from the air conditioning system.
  • Summer Rain: can serve as an acoustic oasis in noisy traffic, cooling and calming with sounds of raindrops on leafy canopies, distant thunder, pattering rain and ambient music soundscapes.

The sounds are based on the audio library "Quiet Planet", which the acoustic ecologist Gordon Hempton has created over the years. The Mercedes-Benz sound design department has arranged the sounds into ten- minute pieces and mixed them for the in-car experience. Individual musical compositions enhance the overall impression of the sounds of nature and their calming effect.

Power Nap: short recovery program for the driver during a break
During a break in a road trip, i.e. at a service area or charging station, the Power Nap program can be selected. The program has three phases - falling asleep, sleeping, and waking up - which can increase the driver's performance and give them new energy. A new feature of the short sleep program during a break is the expanded conditioning of the interior: the EQS ensures a sleep-promoting atmosphere by moving the driver's seat into a rest position, closing the side windows and panorama roof sunshade, activating air ionization, and adjusting the ambient lighting accordingly. Soothing sounds and the depiction of a starry sky on the central display support falling asleep - if Power Nap has been started for the front passenger seat, this also appears on the front passenger display.

Waking up is accompanied by a pleasantly activating soundscape, appropriate fragrance as well as a briefly active subtle massage and seat ventilation. Finally, the seat is raised again and the sunshade in the roof liner is opened. This ends the program and returns the driver to the task of driving.

ENERGIZING COMFORT and ENERGIZING COACH: comfortable travel while staying fit
The ENERGIZING COMFORT range in the EQS builds on the further advanced system of the S-Class. In addition to the three new ENERGIZING NATURE programs, it thus includes the programs Freshness, Warmth, Vitality, Joy and Comfort as well as Training and ENERGIZING Tips.

Visualization benefits from active ambient lighting and large screens with high-resolution animations. Passengers can join a program in progress from their seat ("Join" mode) or suggest their own program to other passengers ("Share" mode). The voice assistant "Hey Mercedes" is integrated. A statement such as "I am stressed," for example, automatically triggers the Joy program with regenerative character. If the driver says "I'm tired," they are then prompted to take a break and ENERGIZING COMFORT starts the Vitality program.

The ENERGIZING COACH is based on an intelligent algorithm. It recommends the Freshness, Warmth, Vitality or Joy program depending on the situation and individual. If the Mercedes-Benz vivoactive® 3 smartwatch, the Mercedes-Benz Venu® smartwatch or another compatible Garmin® wearable is linked, personal values such as stress level or sleep quality optimize the precision of the recommendation. Via the Mercedes me App, the smartwatch sends vital data of the wearer to the ENERGIZING COACH, i.e. pulse rate, stress level and sleep quality. The recommended comfort program can be started directly from the suggestion in the form of a notification in the MBUX system. The aim is to ensure that the driver feels well and relaxed even during demanding or monotonous journeys. In addition, the pulse rate recorded by the integrated Garmin® wearable is shown in the central display.

The ENERGIZING packages contains:

  • The ENERGIZING Package includes ENERGIZING COMFORT, ENERGIZING COACH, AIR-BALANCE Package, driver and front passenger seat climate control, steering wheel heating and the Multi- Contour Seat Package.

1 This package requires the ENERGIZING Package Front and other optional extras.

He who calls for silence

The new EQS under the magnifying glass: Gordon Hempton, American acoustic ecologist

The sounds of the new ENERGIZING NATURE program of the EQS are based on the audio library "Quiet Planet", which nature acoustician and silence activist Gordon Hempton has created over the years. For his recordings, he travels around the world with microphones and measuring instruments.

"As 'The Sound Tracker®,' I've circled the globe three times in the last 35 years to track the rarest natural sounds on earth - sounds that can only be fully appreciated without artificial noise," said Hempton. He now has places certified where only nature can be heard. "I want to preserve the silence before it disappears from the world altogether."

In his book, "The Earth is a Solar Powered Music Box", the Californian recounts how his career began by chance on a summer afternoon some 40 years ago: "I parked the car on the side of the road and lay down in a field to rest. The sky was full of storm clouds. The storm was coming straight at me. And as it rolled and rumbled, even with my eyes closed, I could get a clear picture of the valley and all the surrounding area.

When the storm passed, I was startled. How can I be 27 and have never really listened?" Hempton dropped out of his biology studies at the University of Wisconsin and worked as a bicycle messenger until he saved up the money for an expensive dummy head for high-quality audio recordings.

Hempton has since published numerous albums of recordings of nature and written many books. For the thriller "Survival" he captured the whistling of the wind in the Andes. He supplies software manufacturer Microsoft with sounds for PC games and the "Encarta" encyclopedia. For his television documentary "Vanishing Dawn Chorus" for U.S. network PBS, he won an Emmy in 1992 for "outstanding individual achievement".

In the fall of 2003, Hempton ironically suffered his first bout of sudden deafness. It took 18 months before he could hear properly again. As a consequence, in 2005 he proclaimed the "Square Centimeter of Silence" in the Hoh Rainforest in the U.S. state of Washington, one of his favorite areas of tranquility. Hempton: "Within a year, I got three airlines to change their routes. I wrote them that silence was a protected natural resource, and sent them recordings of their noise pollution to go with it."

Are there still places whose sounds he would like to record? Hempton: "My wish list includes 527 such places Some examples: the mountains of northern Venezuela and the oilbird lives in their caves deep in the forest. I want to explore the soundscape of the cave and hear if the oilbird chirps differently than its close relative, the grey dipper. Singing sand has also fascinated me for a long time. You can find it at the Great Sand Dunes National Monument in Namibia or in Mongolia. Finally, Adak, part of the Aleutian Island chain, is known as the 'Birthplace of the Winds'. I'd love to record the sound of 80 mph fog there in Alaska."

Efficient use of waste heat from the powertrain

The new EQS: Climate control

Even the heat is recycled in the EQS: This saves energy and thus increases the range. Pre-entry climate control is also not only pleasant, but equally efficient. The THERMATIC automatic climate control system with two climate zones is fitted as standard, while the THERMOTRONIC with four zones is available as an option. Sensitive sensor systems and intelligent recirculation controls are part of both.

The intelligent thermal management of the EQS comprises several circuits:

  • The powertrain cooling circuit is used to cool the electric powertrain, the DC/DC converter and the charging components. The sophisticated thermal concept for high load capacity and multiple accelerations with consistently high performance also includes the water lance in the shaft of the rotor of the electric motor. Other cooling elements in the cooling circuit are fins on the stator and the needle-shaped pin-fin structure on the inverter. The transmission oil cooler also brings more efficiency when driving in the cold: The transmission oil absorbs heat from the quickly heated overall system and thus becomes thinner, which reduces friction.
  • A heating circuit for the interior is coupled with the powertrain cooling circuit. As soon as the heating is on, the heat flows through the heating heat exchanger (small heating circuit, electric heater). If waste heat is present in the powertrain, the system switches to the large circuit. Only if its heat is not sufficient, for example at particularly low outside temperatures, is additional heat generated via the high-voltage PTC booster heater (register or series connection). Due to this efficient waste heat utilization, additional heating is often no longer necessary in the temperature range above 41°F, which occurs particularly frequently.
  • The high-voltage battery has its own cooling circuit with separate cooler and chiller (heat exchanger between cooling and refrigeration circuit). For the sake of high durability, the battery is cooled with significantly colder coolant than the powertrain during normal operation. At very high outside temperatures, the coolant is cooled by a chiller connected in parallel to the radiator using the refrigerant from the air conditioning system. This option is mainly used for particularly high fast- charging rates when the vehicle is stationary. A further high-voltage PTC booster heater is integrated into the battery circuit. It has the task of either heating the battery to a temperature level favorable for operation (at temperatures below minus 77° F) or heating it for possible fast charging (at temperatures below 50° F).
  • The interior is cooled by a refrigerant circuit with electric compressor and evaporator. An air-cooled condenser in the cooling module is used for heat dissipation.

Pre-entry climate control: great climate right from the start
The departure time and desired interior temperature can be selected in advance via Mercedes me, i.e. also remotely via the Mercedes me app, or via the central display in the vehicle. Ideally, the EQS is heated or cooled during a charging process so that the energy required for this comes from the grid and does not compromise the range.

During preheating by the pre-entry climate control system, the seats are also heated in addition to the interior air - depending on the equipment. During pre-cooling, on the other hand, the electric air conditioning system switches on and thus lowers the interior temperature. Depending on the equipment, the seat ventilation is also activated.

Air conditioning systems: personal settings in the user profile
Individual climate comfort in the front seats is provided by the standard-fit THERMATIC automatic climate control system with two climate zones: Driver and front passenger can set the temperature separately for their side and save it in user profiles. Thanks to the sensitive sensor system, the interior temperature is automatically kept constant - even in changing weather conditions and varying sunlight.

The integrated activated carbon-based interior air filter works very efficiently and can reduce pollen, pollutants and unpleasant odors in the incoming air in addition to dust and soot particles. The EQS automatically switches to recirculation mode when the system detects a tunnel passage via GPS.

In addition to the comfort setting, the automatic climate control system also offers ECO and ECO + operating modes. With ECO, the operation of the air conditioning is still possible without restrictions with reduced heating and cooling capacity. In ECO + mode, only the fan and, if necessary, the waste heat from the eATS are used. The HV components compressor and heater, on the other hand, remain switched off. ECO and ECO+ reduce the energy consumption of the climate control functions, minimizing losses in vehicle range.

As an optional extra, the EQS is available with THERMOTRONIC automatic climate control with four climate zones. Here, even the rear passengers can enjoy a personal feel-good climate. They can adjust the settings on their own climate control panel. Another difference to the THERMATIC is the even more intelligent recirculation mode: A sensor for air quality and harmful gases continuously monitors the quality of the outside air drawn in and automatically switches to recirculation mode in the event of elevated pollutant levels.

A HEPA filter (High Efficiency Particulate Air) is part of the optional equipment ENERGIZING AIR CONTROL Plus. The HEPA (High Efficiency Particulate Air) filter has a very high filtration level that enables it to trap fine particles, microparticles, pollen and other substances that enter with the outside air. An activated carbon coating reduces sulphur dioxide and nitrogen oxides as well as odors.

Virtual surround sound and extensive sound personalization

The new EQS under the magnifying glass: the Burmester® surround sound system

The standard Burmester® surround sound system is a prerequisite for experiencing the specially designed Sound Experience with the two soundscapes Silver Waves and Vivid Flux. The high-end audio system with 15 loudspeakers, 15 separate amplifier channels and a system output of 710 watts offers many more refinements. These include the three-dimensional surround sound, a personal sound setup, settings focused on individual areas of the interior, as well as the classy design of the speakers with grilles made of metal and Burmester® lettering. MBUX Entertainment is included and enables seamless operation of streaming services via the central display, the steering wheel or the "Hey Mercedes" voice assistant.

In total, the Burmester® surround sound system comprises 15 powerful speakers. Mercedes uses the front bass technology developed in-house: The two subwoofers are integrated into the body shell in the bulkhead on the driver and front passenger side.

Two sound presets allow for different listening enjoyment. If you prefer music that is unadulterated, choose the "Pure" style, which removes effects. A special feature of the "3D sound" mode, on the other hand, is the virtual surround sound. With the help of two 3D speakers in the overhead control panel and a corresponding algorithm, used by the digital sound processor in the amplifier, real surround sound in multi- channel format is generated there.

Further individualization options are offered by the "Sound Focus" and "Equalizer" functions. With the former, the sound is optimized for the front seats, the rear seats or all seats. The equalizer function can be used to adjust bass, mid and treble. Even more convenient: With sound personalization, a setup wizard allows you to enter your music preferences and configure the Burmester® sound system accordingly. The wizard saves the result in a personal profile.

The Burmester® surround sound system automatically has the MBUX Entertainment function on board. It enables seamless operation of streaming services such as Spotify, Amazon Music, TuneIn or TIDAL via the central display, the steering wheel or the "Hey Mercedes" voice assistant.

The Burmester® surround sound system also features Vehicle Noise Compensation (VNC). As a result, the sound impression is maintained in the face of changing driving noises - on the highway as well as in city traffic. An intelligent algorithm continuously decides whether a desired music signal or interfering noise is present and precisely adjusts the sound.

Emotive animations, color feedback and additional visual warnings

The new EQS under the magnifying glass: Active Ambient Lighting

Active Ambient Lighting (standard) in the interior makes it possible to experience which electric driving mode the EQS is currently in: Driving, the boost process and energy recovery are impressively staged with the help of around 190 LEDs. In addition, Active Ambient Lighting is integrated into the driver assistance systems and can visually support their warnings. Color feedback is possible when operating the climate control system or the 'Hey Mercedes' voice assistant, for instance. The ENERGIZING COMFORT programs are also visually supported.

The light band of Active Ambient Lighting, comprising around 190 LEDs, is located above the louver trim element. Along the doors it continues into the rear. When switched off, a matte white line is visible.

When Active Ambient Lighting is switched on, a clearly defined strip of light appears creating an extraordinary experience even during the day.

The individual light sources, which are controlled in real time, stage fluid presentations. For example, the welcome scenario shows a running light when entering the vehicle. Within the luminous line, different color gradients are possible in addition to the 64 individual colors. This makes electric driving also a visual experience: Driving, boosting and energy recovery as well as the different charging states of the EQS are impressively presented.

As an additional contribution to accident prevention, Active Ambient Lighting integrates driver assistance systems and supports them with an animation. Active Brake Assist, for example, warns drivers of the risk of a collision by illuminating the instrument panel in red. With Active Blind Spot Assist, a red light in the door also signals a hazardous situation.

The MBUX voice assistant also comes to life visually and recognizes the position of the person speaking. Active Ambient Lighting signals, for example, that the system is waiting for a voice input.

Active Ambient Lighting is also integrated into the ENERGIZING COMFORT programs. In the Warmth program, for example, the perceptible warmth of the seat, steering wheel and surface heating is accompanied by warm orange-red animations of screen and ambient lighting. In the Vitality program, Active Ambient Lighting radiates a pink-red lighting mood throughout the interior.

Great suspension and ride comfort paired with high driving dynamics

The new EQS: the suspension

The chassis of the new EQS, with a four-link axle at the front and a multi-link axle at the rear, is closely related in design to the new S-Class. The AIRMATIC air suspension with continuously adjustable damping ADS+ is standard equipment. The vehicle level is automatically lowered from around 75 mph to reduce air resistance and thus increase the range. Standard features include rear-axle steering with a steering angle of up to 4.5° for plenty of maneuverability in the city and agility over land.

The standard-fit AIRMATIC air suspension responds particularly sensitively. It combines air suspension bellows with adaptive ADS+ dampers whose characteristics can be fully automatically varied at each individual wheel, in both the compression and rebound stages. While driving, a sophisticated sensor system and algorithms set the dampers according to the quality of the road to ensure that, for example, driving over a bump with just one wheel is not transmitted to the entire axle and the interior. At the front axle the springs and dampers are housed in one suspension strut.

This level control is part of AIRMATIC. It keeps the ground clearance constant irrespective of the vehicle load, but also makes changes. By way of example, in COMFORT mode, the vehicle body is lowered by 0.4 inches at high speeds above 75 mph and another 0.4 inches at over 100 mph to reduce aerodynamic drag and increase handling stability. If the vehicle drops below 50 mph, the body level returns to the initial position. Up to 25 mph the body can be raised by 1 inch at the touch of a button, above 31 mph it is automatically lowered back to normal level.

As maneuverable as a compact car: both axles can do the steering
The aim of the Mercedes-Benz engineers was to make the EQS, which has imposing dimensions, as manageable as a compact car. This impressive driving function was realized via a rear-axle steering system that allows large steering angles (standard: 4.5°, optional 10°) and is integrated into the vehicle dynamics control of steering, brakes and suspension. At the front, the EQS has electromechanical direct steering. The suspension settings of the DYNAMIC SELECT driving modes allow individual adaptation of the assistance characteristics.

DYNAMIC SELECT: The EQS drives the way the driver wants it to
The driver can individually modify the characteristics of the powertrain, ESP®, suspension and steering. The selection is made using a control at the lower end of the central display. The default setting is the COMFORT driving mode, with SPORT, ECO and INDIVIDUAL available as alternatives. The selection is acknowledged by acoustic and visual feedback. The desired driving mode is shown as the status and depicted in the central display.

Rear-axle steering as standard

The new EQS under the magnifying glass: the two versions of rear-axle steering

The standard rear-axle steering with a steering angle of up to 4.5° contributes to the handy and dynamic impression of the EQS. Alternatively, the rear wheels can even turn in by up to ten degrees. This enables a turning circle of 35.7 feet. This corresponds to the turning circle of many models in the compact class. 10° rear-axle steering can also be unlocked later via an upgrade over the air (OTA). The respective rear-axle angles and trajectories are shown in the driving mode menu in the central display.

The interaction between the front-axle and rear-axle steering is configured to ensure agile responsiveness in urban and country traffic together with a very high level of stability. For example, this results in small side- slip angles and a high level of yaw suppression. At high speeds the focus is more on stability, though without compromising precision and responsiveness. This added value is achieved by integrated actuation of the steering and brakes (ESP®), and considerably improves handling safety as a result.

The operating principle of rear-axle steering in detail: An electric motor drives a spindle at the rear axle via a drive belt. This makes axial adjustments to the spindle. Depending on the speed and the steering angle, the rear wheels turn in the same or the opposite direction as the front wheels (same direction or counter- direction). In simplified terms, this produces more agility and a smaller turning circle by counter-steering and more stability with same-direction steering. The environmental data of the vehicle sensors (radar, camera, ultrasonic) are used to adapt the maximum angle to the relevant situation. The system switches from counter- direction to same-direction steering at speeds over 37 mph.

Intelligent support while driving

The new EQS: the driving assistance systems

The basic functions of the systems in the Driver Assistance Package included as standard can be found here.

Active Distance Assist DISTRONIC
On all types of roads – highways, country roads or in town – this intelligent system can automatically maintain a preset distance from vehicles ahead. Special features include:

  • Predictive speed regulation ahead of speed limits
  • Reaction at a driving speed of up to 62 mph to stationary vehicles on the road
  • Selection of DISTRONIC dynamics in MBUX, independently of DYNAMIC SELECT
  • Adjustment of set speed and acceleration for maximum range
  • With the navigation with Electric Intelligence, the charging status at the destination or also at the intermediate charging point can be specified if desired when route guidance is activated. Active Distance Assist DISTRONIC then adjusts the acceleration behavior and, if necessary, the cruising speed to meet this specification.
  • Also new is the adjustment of the set speed at rest areas to 31 mph.

Active Steering Assist
This helps the driver to follow the driving lane at speeds up to 130 mph. Special features include:

  • Lane detection at low speeds additionally with 360° camera
  • Significantly improved availability and performance on bends on country roads
  • Improved lane centering on highways
  • Situation-specific off-centered driving (i.e. following the road edge on country roads with no center marking)

Traffic Sign Assist
In addition to conventionally signposted speed limits, this recognizes overhead frameworks and signs at construction zones. It also includes warnings about running a stop sign and a red light.

Active Lane Keeping Assist
In a speed range of 37 to 130 mph, Active Lane Keeping Assist uses a camera to detect when road markings or road edges are crossed, helping the driver to avoid leaving the driving lane unintentionally. The system also intervenes if there is a danger of collision with detected road users in the adjacent lane, i.e. with overtaking or oncoming vehicles. Special features include:

  • The reaction to detected lane edges, i.e. a grass shoulder
  • Particularly intuitive steering intervention
  • Adjustment of sensitivity via a menu (early, medium, late)
  • The addition of Active Ambient Lighting to warn the driver

Active Lane Change Assist
Active Lane Change Assist cooperatively assists the driver of the EQS when changing to an adjacent lane. A lane change to the right or left is only assisted if the sensors detect that the adjacent lane is separated from the present lane by interrupted lane markings, and no other vehicles are recognized in the relevant danger zone.

Active Emergency Stop Assist
Active Emergency Stop Assist brakes the vehicle to a standstill in its own lane if it recognizes that the driver is no longer responding to the traffic situation for a longer period. Active Emergency Stop assist is particularly useful in the event of a medical or other emergency when the driver is not responding. Active Emergency Stop Assist works in three stages:

  • A continuous acoustic warning, and a visual warning appears in the instrument cluster. The vehicle starts to slow the vehicle down by gently decelerating.
  • Hazard lights are activated, and the driver’s seatbelt is briefly tensioned as a haptic warning.
  • A short, strong brake jolt as an additional warning – followed by the car decelerating to a standstill, with an optional single lane change if necessary.

ATTENTION ASSIST
This system included as standard is able to recognize typical signs of drowsiness and driver inattention, and displays a warning message prompting them to take a break. The additional micro-sleep warning is a new feature. It analyzes the driver's eyelid movements through a camera on the driver's display (only in conjunction with MBUX Hyperscreen). The micro-sleep warning function is already active from speeds over 12 mph.

Active Brake Assist with cross-traffic function
Active Brake Assist uses the on-board sensors to register whether there is a risk of collision with vehicles traveling ahead, crossing or oncoming. The system can give the driver a visual and acoustic warning if a collision appears imminent. If the driver's braking response is too weak, the system can also assist by increasing the brake pressure as the situation demands, and also initiate autonomous emergency braking if the driver fails to respond. Special features are the turning function when starting off (including crossing pedestrians when turning), the cross-traffic function on interurban routes (up to 75 mph) and the warning and braking for oncoming traffic.

Active Blind Spot Assist and exit warning function
Active Blind Spot Assist can give a visual warning - and if the indicators are operated also an audible warning - of potential lateral collisions in a speed range from around 6 to 124 mph. If the driver ignores the warnings and still initiates a lane-change, the system can take corrective action by one-sided braking intervention at the last moment if the speed exceeds 19 mph. When the vehicle is stationary, the exit warning function can warn against exiting because a vehicle or cyclist is passing within the critical area. This function is available at standstill and up to three minutes after the start switch has been turned off. In addition, the hazard display is supplemented with the aid of Active Ambient Lighting (also with the audible vehicle exit warning).

Thanks to the cameras of MBUX Interior Assist, a warning can also be given even if the driver or front passenger merely move a hand towards the door handle in the event of danger.

Evasive Steering Assist
Evasive Steering Assist can assist the driver when seeking to avoid another road user detected by the system in a critical situation. In the new EQS, in addition to standing and crossing pedestrians, pedestrians and vehicles as well as cyclists along the route are also taken into account. The speed range goes up to 68 mph, support is also provided on country routes.

Easy entry into confined parking spaces and narrow entrances

The new EQS: The parking assistants

The EQS comes with the Parking Package with Surround View System as standard. Thanks to powerful sensors that monitor the vehicle's surroundings, the parking systems can help the driver with maneuvering in many areas. The integration of Parking Assist in MBUX makes operation intuitive and fast. Emergency braking functions serve in particular to protect other road users.

The parking systems support the driver in a variety of ways:

... Active Parking Assist also uses the rear-axle steering and thus enters the parking space with ease. The calculation of the lanes (trajectories) is adjusted to this. And when things get really tight, it can make up to 12 moves. Acceleration, steering, braking, gear changes and turn indicators are controlled automatically. The driver remains responsible and has the possibility to intervene at any time and correct or complete the parking maneuver.

... when driving past recognized parking spaces, one press of the button on MBUX is sufficient to start the parking process. This is the Quick Park function of Active Parking Assist.

... the Drive Away Assist can warn the driver if a collision with detected objects could occur when starting off, for example, due to a mix-up of accelerator and brake pedal. The speed is briefly limited in such cases if the danger of collision is detected.

... the Parking Package with Surround View System fuses the information from many sensors and cameras. This will allow more parking spaces to be identified and offered for automated parking, including spaces demarcated by lines (rather than vehicles). There are a total of 12 ultrasound sensors at the front and rear, a rear-view camera in the trunk lid, and three additional cameras in the exterior mirrors and at the front.

... a real-time rendered vehicle model in the Parking Package with Surround View System displays status such as indicating or braking.

... collision protection has been further extended to cross traffic. If the sensors detect other vehicles crossing during forward or reverse travel, the driver is first warned visually and audibly. The rear collision protection goes even further: If the driver does not react and the detected danger persists, the vehicle initiates autonomous emergency braking. These equipment-dependent functions are called Front Cross-Traffic Alert (new) and Rear Cross-Traffic Alert.

... the Active Parking Assist in the EQS also visualizes the distance to obstacles from the driver's perspective with the help of the Active Ambient Lighting. As before, the distance is also transmitted acoustically and displayed on the screen.

Accident protection is not a question of the powertrain concept

The new EQS: Passive safety

The principles of Integral Safety, in particular accident safety, apply regardless of the platform. Like all other Mercedes, the EQS therefore features a rigid passenger cell, special deformation zones and state-of- the-art restraint systems. PRE-SAFE® is standard.

The fact that the EQS is based on an all-electric architecture also opened up new design possibilities for its safety concept. Thus, the installation space for the battery could be favorably selected in a crash-protected area in the underbody. And because there is no large engine block on board, the behavior in a frontal crash could be molded even better. In addition to the standard crash tests, the car's performance in various additional load situations was verified and extensive component tests carried out at the Vehicle Safety Technology Center (TFS).

High-voltage system: automatic shut-down in accidents
The battery, high-voltage (HV) cables and other HV components have been designed and protected in such a way that they meet Mercedes-Benz's high safety requirements in the event of an accident.

The multi-stage protection concept of the high-voltage (HV) system has already proven itself in the other Mercedes-EQ models. In case of danger, it can be automatically switched off and disconnected from the battery. A distinction is made between a reversible and an irreversible cut-off. In the case of a reversible shut-down, which occurs in less severe accidents, it is possible to switch the high-voltage system back on if a prior insulation measurement detects no faults. This means that vehicles still capable of being driven can continue their journey. Only in the case of very severe accidents, where the vehicle is usually incapable of being driven anyway, is the high-voltage system shut down irreversibly and unable to be activated without repair. When shutting down, there is a provision to ensure that within a few seconds there is no residual voltage in the high-voltage system outside the battery that could cause injury.

There are also shut-down points where emergency teams can deactivate the high-voltage system manually. In addition, the EQS has crash monitoring when stationary (during DC charging) as standard.

Acoustic Vehicle Alert System: special sound as a warning for pedestrians
The electric-car-specific innovations also include an Acoustic Vehicle Alert System (standard). This makes it easier for pedestrians to notice the EQS at low speeds. One sound generator sits weatherproof in the front right wheel arch and in the rear underbody respectively. An EQ-specific sound is generated up to a vehicle speed of approx. 19 mph. It becomes louder and higher with increasing speed. This change allows conclusions to be drawn about the driving status (braking/acceleration).

Above 12 mph, the sound is gradually faded out, since above this threshold the vehicle can be perceived via the then dominant rolling and wind noises. If the speed drops back to 18 mph, the sound is faded in again. When reversing, an intuitively recognizable interval tone sounds regardless of the speed.

Modern restraint systems: from belt airbag to window airbag
In addition to driver and front passenger airbags, a knee airbag on the driver's side is also standard. It protects the legs from contact with the steering column or instrument panel in a severe frontal crash. This can prevent or lessen the severity of injuries.

The standard window airbags can reduce the risk of head impact with the side window or penetrating objects. In the event of a serious side collision, the window airbag on the side of the impact extends from the A- to the C-pillar like a curtain over the front and rear side windows. If a rollover is detected, the window airbags can be activated on both sides.

In conjunction with power rear seats with memory function, the EQS is equipped with side airbags in the rear. They protect the chest area on the outer rear seats in the event of a severe side impact and supplement the protection provided by the standard window airbags.

The belt airbags (optional extra) ensure that passengers in the outer rear seats are particularly well protected in the event of a severe frontal collision. The inflatable webbing widens its contact area in the chest and shoulder area almost threefold when triggered. This can reduce the loads acting on the occupants' thorax.

In conjunction with the MANUFAKTUR Nappa leather Package, the EQS has illuminated seat belt buckles at the front and rear. They support buckling up, and make it easy to find the latch at night, because the lights of the belt buckle pulsate at that time. When stationary and at low speed, the lights are solid.

The EQS has child seat attachments as standard on the two outer rear seats. With two anchors each between the seat back and the seat cushion, corresponding child seats are installed particularly quickly and securely. Top tether attachment points behind the rear head restraints provide additional support.

PRE-SAFE®: precautionary protection as standard
The PRE-SAFE® preventive occupant protection system is fitted as standard in the EQS. Together with the familiar precautionary measures in the event of a potential frontal and rear-end crash, PRE-SAFE® Impulse Side forms a kind of virtual crumple zone that extends around the vehicle.

As only a limited crumple zone is available in a side impact, PRE-SAFE® Impulse Side (standard) can move the affected driver or front passenger away from the danger even before the crash as soon as the system detects that a side collision is immediately imminent. For this purpose, air chambers in the side bolsters of the front seat backrest are inflated in fractions of a second.
