Affalterbach, Germany - Mercedes-AMG, the sports car subsidiary of the German premium car manufacturer, is developing a super sports car with zero-emission drive with four electric motors providing a combined peak output of 392 kW. The electric engines are positioned near the wheels, substantially reducing the mass compared to wheel-hub motors, with one transmission per axle transmitting the power.
During the pilot phase the SLS AMG would incorporate 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 energy recuperation during braking.
AMG lists acceleration from zero to 100 km/h at four seconds, putting it at the same performance level as the SLS AMG with a 6.3-litre V8 engine with an output of 420 kW/571 hp.
"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 Mercedes-AMG CEO Volker Mornhinweg,.
The purely electric drive system was born when the new swing-wing model was developed. The sports car is ideally packaged for the integration of zero-emission technology.
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.
