The Mercedes-AMG EQE 43 4MATIC and Mercedes-AMG EQE 53 4MATIC+ go official with up to 500+ km of range

Mercedes-AMG has unveiled a pair of battery-electric business saloons - the Mercedes-AMG EQE 43 4MATIC with a preliminary WLTP ranger of 462-533 km and the Mercedes-AMG EQE 53 4MATIC+ with a preliminary WLTP range of 444-518 km. They are based on the electric-exclusive Mercedes architecture of the luxury and premium class (EVA2). AMG-specific solutions – particularly in the areas of drive, suspension, brakes, sound, exterior and interior design, and equipment – ensure a dynamic and emotively appealing AMG driving experience.

Both new Mercedes-AMG EQE models offer a performance-oriented drive concept with two electric motors. The powerful electric drivetrain (eATS), with a motor on each of the axles, also offers fully variable all-wheel drive, which optimally transmits the drive power to the asphalt under all driving conditions. The power spectrum ranges from 350 kW (476 hp) in the EQE 43 4MATIC to 505 kW (687 hp) in the EQE 53 4MATIC+ with optional AMG DYNAMIC PLUS Package and boost function. The maximum torque ranges from 858 to 1000 Nm. The top speed is limited to 210 km/h for the vanilla model with a 4.2 seconds acceleration from 0 to 100 km/h. The Plus model has a top speed of 220 km/h and up to 240 km/,, with the AMG DYNAMIC PLUS Package and a 0-100 km/h acceleration of 3.5 - 3.3 seconds, respectively.

The AMG-specific electric motors at the front and rear axles are permanently excited synchronous motors (PSM). The decided emphasis on performance is already evident in the output and torque values. In addition, the electric motors are characterised by an optimal balance of power increase, efficiency and noise comfort. The electric motors of the EQE 43 4MATIC feature AMG-specific tuning and control. The EQE 53 4MATIC+ uses AMG-specific electric motors with adapted windings and laminations, higher currents and a specific inverter. This enables higher engine speeds and even more power, which is particularly noticeable during acceleration and at top speed.

The electric motor on the rear axle is particularly powerful thanks to its six-phase design, based on two windings with three phases each. The stator with pull-in winding ensures a particularly strong magnetic field.

Added to this is the highly resilient thermal concept, which allows repeated acceleration manoeuvres with consistently high performance. The centrepiece of the sophisticated design is the so-called water lance in the shaft of the rotor, which cools it. Other AMG-specific cooling elements in the cooling circuit include special ribs on the stator and the needle-shaped pin-fin structure on the inverter, which is made of high-performance ceramics. In addition, there is the transmission oil heat exchanger: In addition to cooling, the oil is also preheated during cold starts to increase efficiency.

The new Mercedes-AMG EQE models are equipped with a powerful 328-volt high-performance drive battery manufactured using the latest lithium-ion technology. It has a usable energy content of 90.6 kWh and consists of ten modules with a total of 360 pouch cells. The battery management system in the EQE 53 is also tuned specifically for AMG. In the Sport and Sport+ drive programs the focus is on performance, in the Comfort drive program the focus is on operating range. The battery generation is characterised by a high energy density and has a high charging capacity. Another new feature is the possibility to install updates for the battery management system over-the-air for continuous improvements over the life cycle. The EQE 53 4MATIC+ also features an AMG-specific wiring harness adapted to the higher performance capability. A major advance in sustainability has been achieved in the cell chemistry: the cobalt content is reduced to ten percent. The optimised active material consists of nickel, cobalt and manganese in a ratio of 8:1:1.

Another advantage of the new battery generation is the short charging times. The energy storage system can charge with up to 170 kW at fast charging stations with direct current. In this case, electricity for 180 kilometres (WLTP) can be recharged in just 15 minutes[3]. Thanks to the onboard charger, the electrified AMG can be conveniently charged at home or at public charging stations with 11 kW or optionally 22 kW with alternating current. In Japan, bidirectional charging will also be possible, i.e. charging in both directions. In addition, there are intelligent charging programs that can be activated automatically depending on the location. Functions such as battery-saving charging make operations even more efficient.

Efficient thermal management also plays a part in shortening charging times. If Navigation with Electric Intelligence is activated, the battery is preheated or cooled while driving to reach the optimal temperature for fast 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.

The battery can also be charged through efficient energy recovery using recuperation. The recuperation power reaches up to 260 kW. The driver can adjust the level of recuperation in three stages via switches on the steering wheel, and receive situation-optimised support from ECO Assist. Here, one-pedal driving and combined braking to a standstill are possible in recuperation levels D and D-. In DAuto, up to 5 m/s² deceleration is achieved, 3 m/s² of which is due to recuperation (2 m/s² via the AMG high-performance brake system). With the help of the optional DRIVE PILOT, deceleration to detected vehicles ahead is automatic until they come to a standstill, for example at traffic lights.

The power of the engines is brought to the road by the standard-fit AMG Performance 4MATIC (EQE 43) or 4MATIC+ (EQE 53) fully variable all-wheel drive. In contrast to previous usage, the "+" in 4MATIC+ stands not only for the fully variable all-wheel drive that EQE 43 and EQE 53 both have, but for the entire additional performance and dynamism that the EQE 53 offers. In both models, the system continuously distributes drive torque between the front and rear axles depending on the driving situation: compared to a mechanical all‑wheel drive system, the electric-specific system ensures a significantly faster response. The torque is checked 160 times per second and adjusted if necessary. The torque distribution depends on the selected drive program: in "Comfort" mode the focus is on maximum efficiency, while in "Sport" and "Sport+" the torque is more rear-biased in the interests of greater lateral dynamics.

The AMG RIDE CONTROL+ air suspension with adaptive adjustable damping is based on a four-link front axle and multilink rear suspension. Both are optimised with AMG-specific wheel carriers, suspension links and anti-roll bars with higher rigidity. It corresponds in its basic features to the suspension of the AMG EQS and the AMG GT Four-Door Coupé, but its set-up has been adapted to the AMG EQE. The rear axle carrier is connected to the body shell with 50 per cent stiffer bearings and reduced bearing clearance to create even more direct road contact. The AMG engineers have specifically tuned all components to meet the special requirements of AMG customers. This applies to ride comfort as well as driving dynamics.

The adaptive adjustable damping uses two so-called pressure limiting valves. These continuously variable control valves located outside the damper allow the damping force to be adjusted even more precisely to different driving conditions and drive programs: one valve controls the rebound phase, i.e. the force generated when the wheel rebounds; the other controls the compression phase when the wheel compresses. The rebound and compression phases are controlled independently of each other. This technology makes it possible to increase comfort on the one hand, but also to make the driving dynamics even sportier on the other hand.

The suspension control unit analyses data – including data from the acceleration and wheel path sensors – to adjust the damping force for each wheel in a few milliseconds to suit the situation. The AMG developers were able to significantly increase the spread between sportiness and comfort. Among other things, by widening the spread between minimum and maximum damping force characteristics, as well as even greater flexibility in characteristic mapping. By using the two adjustment valves, the damper is able to provide damping force adjustment across the full range of wheel vibrations. Thanks to the special design of the valves, the damper reacts quickly and sensitively to changing road surfaces and driving conditions.

Efficiency also feeds into the intelligent driving level control, which enables better aerodynamics and lower power consumption. In the S and S+ drive programs, the Mercedes-AMG EQE models already drive at the low level (-15 mm) from 0 km/h. In drive program C, speed-dependent control takes place with lowering from 120 km/h and raising from 80 km/h.

The high driving dynamics potential is also enhanced by the special tyres, which are specifically adapted to the requirements of the all-electric AMG Performance vehicles, including the MICHELIN Pilot Sport EV designed for sports cars with electric drive.

Both Mercedes-AMG EQE models are equipped with rear axle steering as standard. The steering angle of up to 3.6 degrees promotes agile handling. The interaction between front axle and rear axle steering is designed to achieve agile response with little steering effort when driving in town or on country roads. At speeds below 60 km/h, the rear wheels steer in the opposite direction to the front wheels. This makes the Mercedes‑AMG EQE manoeuvrable, light-footed and nimble. The effect is particularly positive when making a turn, changing direction quickly and manoeuvring slowly. At speeds above 60 km/h, the rear wheels steer in the same direction as the front wheels. The resulting virtually extended wheelbase offers increased handling stability and driving safety at high speeds, and during fast lane changes or sudden evasive manoeuvres.

The AMG high-performance brake system with six-piston brake callipers and 415x33 millimetre brake discs on the front axle delivers first-class deceleration values with high resistance to fading and excellent durability. The rear axle has single-piston brake callipers and 378x22 millimetre brake discs. The optional AMG ceramic high-performance compound brake system uses even larger brake discs measuring 440x40 millimetres at the front (only in conjunction with 21-inch wheels). Another high-tech feature is the intelligent i-Booster brake booster. It ensures that the brake system combines electric recuperation with the hydraulic brake highly efficiently. For that really authentic driving experience, the i-Booster is specially tuned to the characteristic AMG pedal feel and the AMG brake system.
