Mercedes-AMG has taken the wraps off its first all-electric series production model, the EQS 53 4Matic+. With a twin-motor set-up offering up to 751hp, it will take on the Porsche Taycan Turbo S and Audi RS E-tron GT.
To be followed by a range of AMG EVs
Can do 0-100kph in 3.4sec
Top speed limited to 220kph on standard, 250kph on Dynamic Plus variants
Mercedes AMG EQS 53 4Matic+: first of many more
The new luxury performance sedan from Mercedes-AMG will serve as the flagship model for both, the EQS range and Mercedes-Benz’s line-up of bespoke electric cars. It will be followed by a range of AMG EVs, including hot versions of other EQ models built on the EVA2 platform, as well as dedicated AMG models using the AMG.EA architecture.
The EQS 53 incorporates extensive technical changes from regular versions of the electric limo, including an AMG-specific electric performance motor mounted on each axle. The motors feature new windings, stronger currents and new actuation via inverters, which allows for higher rotational speeds within the unit.
These upgrades have allowed AMG to boost the power and torque of the permanently synchronous motors. Standard EQS 53 models will offer 649hp, while those fitted with the Dynamic Plus package will have a Race Start mode that can increase output to 751hp. In that mode, the EQS 53 can cover 0-100kph in 3.4sec – 0.4sec quicker than the standard time. The top speed is limited to 220kph on standard models and 250kph on Dynamic Plus cars.
Power is stored in a 107.8kWh lithium-ion battery with a 400V architecture, which features bespoke AMG wiring to aid performance and offer a range of 326 to 360 km, depending on spec. The battery management system has been customised for the EQS 53, enabling greater performance in Sport and Sport+ driving modes. When driving, three levels of energy recuperation are available using switches on the steering wheel. The battery can be charged at speeds of up to 200kW on a fast charger.
As with the regular EQS, the new model’s suspension features multi-link front and rear axles, although AMG says it has redeveloped any components that have “an influence on the driving dynamics”, including the rear axle beam and both the subframe and the motor mountings.
The car is equipped with AMG’s Ride Control+ air suspension, which combines with electronically controlled active dampers and standard rear-axle steering. As with the Mercedes-AMG GT 4-Door Coupé, the air suspension set-up has two pressure relief valves that, AMG claims, allow the damping force to be adjusted “even more precisely” to different driving conditions. The suspension system can also analyse sensor data to alter the damping force.
The model features a range of AMG driving modes, which adjust the suspension, handling, power delivery and battery management, as well as changing the synthesised sound to suit. There is a choice of 21-inch or 22-inch wheels, with high-performance AMG brakes as standard. Larger ceramic brakes are optional. New AMG modes are available as part of the standard EQS Sound Experience system and include a Performance setting for Dynamic Plus models that adds “event sounds” for all vehicle functions.
The EQS 53 sports a number of bespoke AMG styling elements, many of which reflect the tuning arm’s classic design traits. These include a bespoke black panel front grille with ‘hot-stamped’ chrome vertical struts, and a reworked front bumper and apron. While the new machine matches the 0.23Cd of the regular EQS, AMG says it has conducted wind tunnel testing to optimise the airflow, hence the reworked rear diffuser, side air intakes and a bigger rear spoiler
