Mercedes-AMG Unveils All-Electric Performance Sedan
Mercedes-AMG has unveiled a new, all-electric performance sedan, the EQE.
The vehicle is outfitted with AMG-specific solutions – particularly in the areas of drive, suspension, brakes, sound, exterior and interior design, and equipment, the German automaker said.
The new Mercedes-AMG EQE offers a performance-oriented drive concept with two electric motors. The electric drivetrain (eATS), with a motor on each of the axles, also offers fully variable all-wheel drive. The AMG EQE produces an impressive power output of 677 horsepower and 738 lb.-ft. when equipped with the AMG DYNAMIC PLUS Package and boost function.
The EQE is also features a sound system that creates a unique sound experience with the help of special speakers, a bass actuator and a sound generator, the automaker said. There are “Authentic” and optional “Performance” sound programs available for selection. Both are available in three variants each: “Balanced”, “Sport” and “Powerful.” The tonality and intensity of the AMG SOUND EXPERIENCE is tuned to the current driving status, selected drive program or driver’s preference, both inside and out.
The AMG-specific electric motors at the front and rear axles are permanently excited synchronous motors (PSM). The AMG EQE 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 company said. 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 maneuvers with consistently high performance, designers said. The centerpiece of the design is the 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 model is equipped with a 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 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 characterized 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 AMG EQE also features an AMG-specific wiring harness adapted to the higher performance capability.
The new generation battery also offers quicker charging times, Mercedes-AMG said, as the energy storage system can charge with up to 170 kW at fast charging stations with direct current. In this case, electricity for 180 kilometers or 112 miles (WLTP) can be recharged in just 15 minutes. Thanks to the onboard charger, the electrified AMG can be charged at home or at public charging stations with alternating current.
The AMG RIDE CONTROL+ air suspension with adaptive adjustable damping is based on a four-link front axle and multilink rear suspension. Both are optimized with AMG-specific wheel carriers, suspension links and antiroll bars with higher rigidity.
The adaptive adjustable damping uses two 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 independently controls the rebound phase while the other independently controls the compression phase. A suspension control unit analyzes data – including data from the acceleration and wheel path sensors – to adjust the damping force for each wheel, the company said.
An AMG high-performance brake system with six-piston brake calipers and 16.3-inch x 1.3-inch brake discs delivers stopping power on the front axle, while single-piston brake calipers and 14.9-inch x 0.87-inch brake discs are equipped in the rear. An optional AMG ceramic high performance compound brake system uses even larger brake discs measuring 17.3-inch x 1.6-inch at the front.
