SLS AMG E-CELL: The gullwing going green! Mercedes-AMG is accepting the challenges of motoring of the future: the SLS AMG E-CELL is evidence of the state-of-the-art development of an exciting super sports car featuring a zero-emission high-tech drive.
The ground-breaking drive system of the technology vehicle boasts some out-standing 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.
When it comes to dynamics, the electrically-powered SLS AMG makes a state-ment: the gullwing model accelerates from zero to 100 km/h in 4 seconds – which almost puts it on the same high level as the SLS AMG with 6.3-litre V8 engine developing 420 kW (571 hp), which can accelerate to 100 km/h in 3.8 seconds.
Externally, the SLS E-Cell has received a few tweaks to differentiate it from the petrol car. Aside from the radioactive paint job, the car receives energy-saving LED headlights, a wider grille and an automatically extending front splitter, which is deployed above 75mph to increase downforce at higher speeds.
Inside the E-Cell the centre console has been redesigned to accommodate instruments specifically for the electric drive system. And Mercedes has installed a huge 25cm touchscreen, replacing almost all the dashboard buttons in the process.
The interior appointments are dominated by high-quality nappa leather in a black/white colour combination – it has been used not only on the sports seats, the performance leather/alcantara steering wheel and the door linings, but also on the broad centre tunnel which runs towards the back of the vehicle between the seats.
Unlike most electric concepts, Mercedes has promised to have this on sale by 2012. Prices are still to be announced, but expect a heavy premium for this futuristic electric supercar. |
