Mercedes-Benz plans electric SLS supercar
Dubai, July 22, 2009
Mercedes-Benz has revealed that plans are underway to produce an electric version of the Mercedes-AMG SLS supercar.
The zero-emission supercar draws heavily on the production version of the SLS which makes its world premiere in Frankfurt on September 15.
“With the electric drive SLS AMG we wanted to redefine the super sports car,” said Frank Bernthaler, director, Mercedes-Benz Cars, Middle East & Levant.
“For Mercedes-Benz, it is not just about responsibility, it is also about excitement and classic AMG performance,” he added.
The electric drive SLS will have the same lightweight aluminium body as the production version of the SLS, complete with its signature gullwing doors. It will have an electric motor near each wheel substantially reducing the unsprung masses compared to wheel-hub motors. One transmission per axle transmits the power.
This effectively turns the car into an all-wheel drive vehicle allowing dynamically optimised power transmission without any power loss by means of torque vectoring.
In its pilot phase, the electric drive SLS AMG incorporates a liquid-cooled high voltage lithium-ion battery with an energy content of 48kWh. The 400-volt battery is recharged by means of targeted recuperation during braking.
The 6.3 litre V8 engined SLS will produce 571 hp and only 479 ft lb of torque, while the electric drive car, by comparison, has 532 hp and a sizeable 649 ft lb of torque giving it a planned under four-second 0-100 km per hour figure, similar to that of the petrol-engined SLS.
The battery pack will be mounted in front of the firewall, in the centre tunnel and in the space behind the seats normally taken up by the fuel tank. – TradeArabia News Service
