Mercedes-Benz SLS AMG E-Cell Prototype: The All-Electric Gullwing [With Video]


Approximately a year ago, Mercedes-Benz officially revealed plans to develop a fully-electric version of its SLS AMG supercar. Now, the German automaker has unveiled a prototype model of the car named "SLS AMG E-Cell".

On the E-Cell prototype, Stuttgart's engineers replaced the standard SLS AMG's 571HP 6.3-liter V8 petrol engine with four electric motors placed near the wheels effectively making it a four-wheel drive model. Mercedes notes that this solution substantially reduces the unsprung masses compared to wheel-hub motors.

The electric motors produce a combined output of 392kW or the equivalent of 526HP and a maximum torque of 880 Nm / 649 lb-ft, the latter available right from the start. One transmission per axle transmits the power.
