Mercedes-Benz SLS E-CELL electric supercar by AMG

The AMG division of Mercedes-Benz has created a yellow prototype called the SLS AMG E-CELL, an electric version of their gullwing sports car that features a zero-emission high-tech drive.

Finished in fluorescent “AMG lumilectric magno” paint, the gullwing reflects the innovative strength and development competence of the AMG brand.

Those motors, which top out at a screaming 12,000 rpm, combine to apply 526 hp and 649 lb-ft of torque to the wheels – sufficient to push the coupe to 60 mph in under four seconds. The installation of the front motors necessitated the replacement of the double-wishbone suspension with a multi-link setup with push-rod dampers.

As a result, compared with wheel-hub motors the unsprung masses are substantially reduced. One transmission per axle transmits the power.

The SLS AMG E-CELL 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 maximum electric load potential of the battery, which consists of 324 lithium-ion polymer cells, is 480 kW, which is an absolute best value in the automotive sector. Another technical feature of this considerable performance is the intelligent parallel circuit of the individual battery modules which helps to maximize the safety, reliability and service life of the battery. The 400-volt battery is charged by means of targeted recuperation during braking whilst the car is being driven.

The transformation from petrol to electric super sports car also called for some specific changes to the interior. As a result, the AMG instrument cluster and centre console in particular both feature a new design. The new AMG instrument cluster provides information on speed, charge status of the battery and the estimated range. The newly designed centre console now houses a 10-inch 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.

The AMG Drive Unit, which is angled towards the driver, houses buttons for starting the motor, ESP functions, the AMG memory function and the extendable front splitter and rear spoiler. Using three new buttons, the driver can switch simply between P, R and D. The park setting is enabled automatically by switching the electric motors off.

The production version will come in 2013.
