Mercedes-Benz showcased its SLS AMG E-Cell concept car at the Detroit Motor Show, however, the big news wasn't the presentation of the all-electric supercar but the announcement that it will enter production within the next couple of years.
"The Mercedes-Benz SLS AMG E-CELL is the most technically advanced super sports car in the 125-year history of the automobile, and shows just how fascinating electromobility can be," said Dr. Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars, at the press conference. "Our customers will be able to order it from their Mercedes-Benz dealers from 2013 onwards."
At the heart of the all-electric supercar are four, high-revving, synchronous electric motors, which can reach 12,000 rpm, producing a combined output of 526 hp (392 kW) with a peak torque of 880 Nm (649 lb-ft) of torque, enough to catapult the E-Cell to 100 km/h (62 mph) in just 4 seconds or almost as fast as the stock SLS’ 571 hp V8 gasoline engine (3,8 seconds).
The E-Cell’s drive is also comprised of a liquid-cooled lithium-ion battery featuring a modular design and a maximum electric load potential of 480 kW. Aside the power outlet, the 400-volt battery can also be charged by the regenerative braking system.
It might be a green machine, but the E-Cell is also a thoroughbred sports car. By positioning the electric motors as close to the wheels as possible and carefully placing the battery modules throughout the chassis, engineers managed to obtain a near-perfect weight distribution. The new front suspension, boasting a multilink setup with pushrod damper struts, is another feature usually found on high performance cars, alongside the oversized ceramic composite brakes.
Finished in a fluorescent “AMG lumilectric magno” paint, the body has been fitted with an extensive aerodynamic kit. The 10-spoke 19-inch AMG alloys, shod in 265/35 front and 295/30 rear tires, round up the exterior appointments.
Inside, there’s a new instrument cluster and center console housing a 10-inch display, used to operate all audio, climate and navigation functions. Other touches include the black/white nappa leather combination, sport seats and steering wheel.

While we can only speculate on the unnamed concept model, it is very likely that the AMG production car is the SLS AMG Roadster as it was recently teased in the German firm’s SuperBowl commercial.
