The Mercedes-Benz SLS AMG with electric drive will transform the vision of powerful and emission-free super-sports cars into reality thanks to an innovative drive system: powerful forwards thrust is provided by four electric motors with a combined peak output of 525hp and a maximum torque of 574 lb-ft.
The four electric motors are positioned near the wheels, substantially reducing the unsprung masses compared to wheel-hub motors. One transmission per axle transmits the power. This intelligent all-wheel drive system allows dynamically optimized power transmission without losses by means of Torque Vectoring.
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 40Ah. The 400-volt battery is charged by means of targeted recuperation during braking while the car is being driven.
The electrically driven SLS AMG delivers an unequivocal statement: the swing-wing model accelerates from 0-62mph in around 4 seconds - putting it on the same level as the SLS AMG with a 6.3-liter V8 engine developing 571hp.
"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," said Volker Mornhinweg, CEO 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. It is ideally packaged for the integration of the high-performance, zero-emission technology. For example, the four electric motors and the two transmissions can be positioned near the wheels and low in the vehicle. The same applies to the modular battery, whose modules are located in front of the firewall, in the centre tunnel and behind the seats. Advantages of this solution include the vehicle's low centre of gravity and the balanced weight distribution - ideal conditions for optimum handling, which the electric powered SLS AMG shares with its gasoline-driven equivalent.
The installation of the drive components required no changes to the swing-wing model's aluminum spaceframe body. And there were just as few constraints when it came to maintaining the level of passive safety and long-distance comfort.
The electrically powered SLS AMG sees Mercedes-Benz and AMG continuing to minimize the amount of time it takes to produce an electric car. Their strategic involvement in Deutsche Accumotive GmbH & Co. KG, a joint venture between Daimler AG and Evonik Industries AG, will provide the battery technology required in future. Daimler has the leading role in this joint venture for the development and production of batteries and battery systems for automotive applications.
