Mercedes is planning a zero-emission electric SLS AMG supercar which will accelerate to 62mph in 4 seconds.
The Mercedes-Benz SLS AMG with electric drive has four electric motors with a combined peak output of 392 kW and a maximum torque of 880 Nm.
The four motors are positioned near the wheels, reducing the unsprung mass compared to wheel-hub motors. One transmission per axle transmits the power. This intelligent all-wheel-drive system allows specifically targeted acceleration of individual wheels.
In its first pilot phase, the SLS AMG with electric drive incorporates a liquid-cooled high-voltage lithium-ion battery of modular design with an energy content of 48 kWh and a capacity of 40 Ah. The 400-volt battery is charged by means of targeted recuperation during braking whilst the car is being driven.
The zero to 100 km/h acceleration in around 4 seconds is comparable to the SLS AMG with a 6.3-litre V8 engine developing 420 kW/571 hp.
“With the SLS AMG with electric drive, we wanted to redefine the super sports car. For us, it is not just about responsibility. We attach just as much importance to excitement and classic AMG performance,” says Volker Mornhinweg, Chief Executive Officer of Mercedes-AMG GmbH.
The purely electric drive system was factored into the equation as early as the concept phase when the new swing-wing model was being developed by Mercedes-Benz and AMG.
The four electric motors and the two transmissions can be positioned near the wheels and very low down in the vehicle. The same applies to the modular high-current battery, whose modules are located in front of the firewall, in the centre tunnel and behind the seats. The low centre of gravity and balanced weight distribution should mean excellent handling.
