Depending on the onboard equipment and configuration, WLTP operating ranges of up to 654 kilometres[1] are possible.

The torque delivered to the wheels by the eATS (electric drivetrain) is checked 10,000 times per minute and adjusted if necessary. This enables a much quicker response in the later versions with 4MATIC than with mechanical all-wheel drive.

The EQE is available with rear-axle steering as an option. Two versions are available, with a steering angle of up to 4.5 degress[2]and up to 10 degrees respectively. The turning circle is reduced from 12.5 to up to 10.7 metres with 10° rear-axle steering.

The electric motor on the rear axle has 2 windings with 3 phases each. This 6-phase design makes this permanently excited synchronous motor (PSM) particularly powerful.

DIGITAL LIGHT (optional extra) has a light module in each headlamp with three extremely bright LEDs whose light is refracted and directed with the help of 1.3 million micro mirrors. The resolution is therefore more than 2.6 million pixels per vehicle.

Mercedes me Charge[3] has one of the densest charging networks, with around 700,000 charging points, including more than 300,000 in Europe.

With the MBUX Hyperscreen, multiple displays merge seamlessly to create an impressive curved screen band over 141 centimetres wide. The area perceived by the occupants measures 2432.11 sq. cm.

The large glass covering the MBUX Hyperscreen is curved in three dimensions in a moulding process at temperatures of approx. 650°C. 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.

A lithium-ion battery with 10 cell modules is installed in the EQE. In the case of the battery, a major step has been achieved in terms of the sustainability of the cell chemistry: the optimised active material consists of nickel, cobalt and manganese in a ratio of 8:1:1.

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

No.6 MOOD bittersweet is the name of the fragrance composed especially for the EQE, based on the aroma of dark chocolate. It bears the number 6 because the first electric cars were added to the model range in 1906 in the form of the "Mercédès Electrique" vehicles.

To get to the most important applications of MBUX, the user has to scroll through 0 menu levels. Hence the term zero layer.

The screen of the optionally available head-up display has a diagonal of 29 inches. A virtual image, in colour, appears to float above the bonnet at a distance of about 4.5 metres.

The HEPA (High Efficiency Particulate Air) filter as part of the optional ENERGIZING AIR CONTROL Plus, with a volume of 9.82 dm³, cleans the incoming outside air at its very high filtration level. Up to 99.75 percent of particles are separated out. Around 600 grams of activated charcoal are used to neutralise odours. 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 EQE is also one of the first vehicles to be built with steel from Salzgitter AG, which is 100 percent recycled. This reduces the CO2 emissions in rolled steel production by more than 60 percent.

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

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

A DC box with a charging capacity of up to 170 kW is fitted on board for (fast) charging via direct current. In 15 minutes it is possible to charge the EQE with up to 35.55 kWh – this corresponds to a range of up to 250 kilometres based on the WLTP range[4].

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

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

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

For high noise and vibration comfort, the electric drivetrains (eATS) have a special foam mat all around as an NVH cover. The lid of the inverter has a sandwich construction of 3 metal and plastic layers.

The battery certificate stands for the long service life of the high-voltage batteries. It is valid up to a term of ten years or up to 250,000 kilometres.

The new EQE: the exterior design

Apr 13, 2022
Stuttgart

The EQE features a sporty 'purpose design' with all the characteristic elements of Mercedes-EQ, one-bow lines and cab-forward design. Sensual Purity is reflected in generously modelled surfaces, reduced joints and seamless transitions (seamless design). The overhangs and the front end are kept short, the rear provides the dynamic accent with a sharp rear spoiler. Flush with the outer edge of the body, the 19- to 21‑inch wheels, together with a pronounced muscular shoulder section, give the EQE an athletic character.

Compared to the luxury liner EQS, the EQE is even more streamlined, with a slightly shorter wheelbase, shorter overhangs and more recessed flanks - it carries the concept of the business saloon into the future.

The sporty, low and slim front of the EQE forms a coupé-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 create space for a generous passenger compartment. Unique in this segment is the cab-forward design: The overhangs and the front-end assembly are short, the rear forms a dynamic accent with a sharp rear spoiler. Flush with the outer edge of the body, wheels of around 725 mm in size on 19- to 21-inch rims, together with a muscular shoulder section, give the EQE an athletic character.

The design philosophy of Sensual Purity is implemented with the clear, flowing design. Tense, sinewy surfaces emphasise the athleticism, and the claim of seamless design is confidently realised with reduced lines and flowing transitions. Aerodynamics and formal aesthetics are synergistically coordinated. 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 and the deep black radiator grille (Black Panel) form the athletic face and simultaneously position the EQE as a member of the new Mercedes-EQ vehicle generation. In addition to its unique look, there is also function behind the Black Panel surface: the various sensors of the driving assistance systems such as ultrasound, camera and radar are integrated. The concise daytime running light signet interprets the brand's characteristic flare. LED High Performance headlamps are standard, DIGITAL LIGHT combined with the flare as daytime running lights is available as an optional extra.

The exclusive look of the Black Panel radiator grille with the central Mercedes star can be enhanced still further: in conjunction with AMG Line exterior or Electric Art exterior, they are also available as an optional extra with the Mercedes-Benz pattern, a three-dimensional star pattern. This references the original star of the Daimler-Motorengesellschaft company, which was registered as a trademark in 1911. The seamless design is reflected in the front-end design in particular. Examples include the reduced gap dimensions and overlapping bonnet. The latter does away with the traditional divide between bonnet and wings.

Striking one-bow lines

The aerodynamic silhouette with frameless, coupé-like doors and the high, arched beltline are independent design elements in the profile. The outside mirrors sit on the beltline and are aerodynamically and aero-acoustically optimised. Chrome accents highlight design focal points like the one-bow lines of the window graphics. High-quality painted contrasting surfaces can be found in the lower area of the vehicle. Stone chip protection has been integrated into the chrome trim.

The service flap for wiper fluid was integrated into the side of the left wing. The bonnet is only opened by the specialist workshop for maintenance work, such as replacing the interior air filter.

Light band with LED lamps in 3D helix design

The sporty, coupé-like rear carries a rear spoiler with a sharp spoiler lip. The large rear window, which extends downwards from the roof in a flowing contour, is a distinctive feature. For the first time, the components of the various aerials are hidden underneath, invisible from the outside. The boot lid joins the windscreen with a slight gradation and unobtrusively incorporates the additional brake light. The rear camera is hidden behind the star, protected from dirt. Another highlight at the rear are the innovatively designed LED lights: their insides have the shape of a curved and illuminated 3D helix.

The EQE has a continuous light band at the rear - a distinguishing feature of Mercedes-EQ vehicles.

The new EQE: electric drive

Apr 13, 2022
Stuttgart

The market launch will see the debut of the EQE 350+ (WLTP: combined electrical consumption: 18.7‑15.9 kWh/100 km; combined CO2 emissions: 0 g/km)[1] with 215 kW and the Mercedes-AMG EQE 43 4MATIC (WLTP: combined electrical consumption: 22.5-19.7 kWh/100 km; combined CO2 emissions: 0 g/km). With 350 kW, this is the entry-level model for electric Driving Performance from Mercedes-AMG. The EQE 500 4MATIC (provisional figures WLTP: combined electrical consumption: 21.1-17.8 kWh/100 km; combined CO2 emissions: 0 g/km) [2] and Mercedes-AMG EQE 53 4MATIC+ (provisional figures WLTP: combined electrical consumption: 23.2‑20.3 kWh/100 km; combined CO2 emissions: 0 g/km) will follow. The battery of the EQE 350+ has ten modules with a usable energy content of around 90 kWh, while the range of up to 654 km1 according to WLTP makes the car absolutely viable for long distances.

All EQE models have an electric drivetrain (eATS) on the rear axle. The versions with 4MATIC also have an eATS on the front axle. In the 4MATIC models, 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 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 stator windings. In the EQE, Mercedes-Benz uses what is known as a pull-in winding for a particularly strong magnetic field. The engine is referred to 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 converters 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 characterise the EQE's drive philosophy. This includes a sophisticated thermal concept with some special features. What is known as 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 EQE offers several variants of energy recovery by means of recuperation: in this process, the high-voltage battery is charged by converting the mechanical rotary motion into electrical energy during overrun or braking mode. The driver can manually select the deceleration in three stages (D+, D, D-) as well as the gliding function via shift paddles behind the steering wheel. Also available: DAuto.

ECO Assist also offers situation-optimised recuperation - 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 for vehicles detected ahead until they come to a standstill, for example at traffic lights. The driver does not need to press the brake pedal for this - literally one-pedal driving.

Noise and vibration comfort: conceptual advantage plus extensive measures

As a saloon with a boot lid, the EQE's concept is well equipped to offer a high level of NVH comfort. Numerous measures contribute to this:

Even the design of the electric powertrains (eATS) takes noise and vibration comfort (NVH - Noise, Vibration, Harshness) into account. The magnets are arranged inside the rotors in an NVH-optimised way (known as 'sheet metal cut'). This also reduces the use of rare earths. The shape of the winding, what is known as 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 very slowly.

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

Highly effective spring/mass components provide continuous sound insulation from the crossmember under the windscreen to the floor of the boot. Acoustic foams are inserted into many carriers during body-in-white construction.

The electric refrigerant compressor has an NVH cover as encapsulation. In the rear-wheel-drive EQE, it is also soft-suspended, while in the 4MATIC models it is bolted directly to the front eATS. The operating strategy of the refrigerant compressor also contributes to the particularly low noise level of the vehicle. Certain rpm ranges at which disturbing resonances may be audible when stationary or in a traffic jam are avoided or quickly passed through.
