Mercedes-Benz SLS AMG E-Cell

The Mercedes-Benz SLS AMG E-Cell is a special prototype derived from the production Gullwing featuring an all-electric powertrain with four electric motors delivering a total of 525 hp and 880 Nm. It could preview a possible limited series edition model.

Mercedes-Benz SLS AMG E-CellDeveloped with the ambition of creating the “sportiest electric car ever”, the Mercedes-Benz SLS AMG E-Cell is powered by four synchronous electric motors with a combined peak output of 525 hp and a maximum torque of 880 Nm. The transmission is a permanent all-wheel drive system.

The four compact electric motors each achieve a maximum rpm of 12,000/rpm and are positioned near to the wheels. As a result, compared with wheel-hub motors the unsprung masses are reduced.

The SLS AMG E-Cell accelerates from zero to 100 km/h in 4 seconds – almost on the same level as the SLS AMG with 6.3-litre V8 engine.

Mercedes-Benz SLS AMG E-CellThe car drive incorporates a liquid-cooled high-voltage lithium-ion battery featuring a modular design with an energy content of 48 kWh and a capacity of 40 Ah.

The installation of the drive components required no changes to the model’s aluminium spaceframe.

At the front the standard double wishbone axle has been replaced by an independent multilink suspension with pushrod damper struts, in order to make way for the additional drive shafts.

The system also adopts acing-derived horizontal damper struts operated via separate push rods and transfer levers.

The over-sized brake discs – measuring 402 x 39 mm at the front and 360 x 32 mm at the rear – are made of carbon fibre-strengthened ceramic.

The ABS and ESP® systems have been adapted to match the special application spectrum of the permanent all-wheel drive.

Exterior Design

Underlining the car’s exclusive and dynamic character, the SLS AMG E-Cell is finished in a fluorescent “AMG lumilectric magno” paint.

At the front, the design is characterized by the new dynamically shaped full-LED headlamps with integrated daytime driving lights which contribute to increase the vehicle efficiency and range.

The air outlet openings on the hood and the vehicle sides have also been modified for enhanced aerodynamics.

All trim and detachable parts, which are finished in chrome or silver shadow on the standard SLS AMG, are now finished in matt black.

The front apron has not only been brought further forward, but also helps to guarantee an optimised airflow in the area of the underbody.

An extendable front splitter enhances this effect: in parallel with the automatic rear spoiler, it extends downwards by seven centimetres at speeds above 75 mph and helps to further accelerate the air which travels beneath the car.

When it reaches the area of the rear axle, the air enters the rear diffusor which, due to the lack of an exhaust system, features a steeper angle, thus increasing downforce at the rear axle and in turn further enhancing the aerodynamic balance.

The vehicle’s AMG 10-spoke light-alloy wheels featuring a new, smooth-surfaced design are fitted with 265/35 R 19 (front) and 295/30 R 20 (rear) tyres.


Inside, the instrument cluster and centre console have a new design. The console now houses a 25 cm touchscreen, which driver and passenger can use to conveniently operate all of the audio, climate and navigation functions, and also obtain information on the flow of power from the four electric motors.
