The Mercedes-Benz SLS AMG E-Cell, the performance brand of Mercedes-Benz is launching a totally innovative drive solution for super sports cars and as such is among the pioneers in this market segment.
The ground-breaking drive system of the technology vehicle boasts some outstanding features: powerful traction is provided by four synchronous electric motors with a combined peak output of 392 kW and a maximum torque of 880 Nm. 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 substantially reduced. One transmission per axle transmits the power.
Acceleration from zero to 100 km/h in 4 seconds. When it comes to dynamics, the electrically-powered SLS AMG makes a statement: the gullwing model accelerates from zero to 100 km/h in 4 seconds - which almost puts it on the same high level as the Mercedes SLS AMG with 6.3-litre V8 engine developing 420 kW (571 hp), which can accelerate to 100 km/h in 3.8 seconds. Further exciting touches are provided courtesy of the agile accelerator response and the straight-line performance: unlike the combustion engine, torque build-up with an electric motor is instantaneous - maximum torque is available virtually from a standstill. The spontaneous torque build-up and confident power delivery - which does not suffer from any interruption of tractive power - are combined with engine running characteristics which are totally free of vibration.
The Mercedes-Benz 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 - this also helps to maximise 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.
