Proving that not all electric cars will have to be dull, the SLS AMG E-CELL is powered by four electric motors that combined produce 525 bhp (392 kW / 532 PS) and 880 Nm (649 lb/ft) of torque. Each of those motors is placed close to its own wheel, creating an intelligent all-wheel drive system.
At the moment, a liquid-cooled, high-voltage lithium-ion modular battery is being used for the prototypes. Its energy content is 48 kWh, with a rated capacity of 40 Ah at 400 volts. The SLS AMG E-CELL will also benefit from regenerative braking, which will top-up the battery’s charge during normal driving.
The only performance figure released so far is the 0-100 km/h (62 mph) acceleration time, which is said to be around 4 seconds. By comparison the petrol-powered SLS AMG, with its 563 bhp (420 kW / 571 PS) and maximum torque of 650 Nm (479 lb/ft), does the same sprint in just 3.8 seconds. So, despite some extra torque, the electric version is marginally slower off the line. That probably indicates it’s hauling around a little added weight?
Two vital stats that have yet to be revealed are battery recharge time and the car’s range. These will be critical in establishing whether the SLS AMG E-CELL can tempt customers away from the existing V8-powered version.
