2012 Mercedes-Benz SLS AMG Coupe Electric Drive
2012 Mercedes-Benz SLS AMG Coupe Concept will be coming in Electric model. At 2012 Paris Auto Show, Mercedes-Benz has officially unveiled SLS AMG Coupe Electric Drive photos and specification detail with pricing and targeting market.
2012 Mercedes-Benz SLS AMG Coupe Electric Drive powered by four electric motors positioned close to the wheels which can produce maximum 740 horsepower (552 kW or 751 PS) and 737 pound-feet (1000 Nm) of torque. With these power, the SLS AMG Electric Drive will accelerate from 0 to 62 mph (100 km/h) in only 3.9 seconds and easily reach its electronically limited top speed of 155 mph (250 km/h). The fastest 583-horsepower SLS AMG GT gasoline, only needs only 3.6 seconds to reach 62 mph, though it isn’t hindered by a heavy battery pack.
The SLS AMG Electric Drive battery pack weighs just over 1,200 pounds, and is rated at 60 kWh. It has a range of about 150 miles with mixed driving. Charge time takes more than 20 hours using an ordinary household outlet, though Mercedes-Benz plans to offer a quick-charge option.
But it’s not just about brute power with this car. Like the original concept versions, the production SLS AMG Electric Drive packs four motors, one mounted to each wheel via an axially-arranged transmission design. By controlling the torque of each of these motors through a new AMG Torque Dynamics system, the vehicle promises to handle much better than its gasoline counterparts.
The technology behind the AMG Torque Dynamics system was developed together with engineers from the Mercedes-AMG Formula 1 team, who were able to contribute their extensive know-how with KERS hybrid concepts. Note, Ferrari’s replacement for the Enzo supercar is expected to feature its own setup relying on this principle.
To counteract the heavy batteries is a full carbon fiber monocoque, another feature that should help the SLS AMG Electric Drive stand out from the regular model. Though costly, adopting carbon fiber for the car’s central structure helps engineers achieve the high standards of performance implied by the AMG badge. Benefits include a weight saving of around 30 percent over standard aluminum, but high strength too. But the changes don’t end there. Racing-style pushrod shocks replace the vertically-arranged system in the regular SLS AMG, as the electric drive system–and the now driven front wheels–required a different axle setup. The brakes are carbon ceramic units.
On the outside, SLS AMG Electric Drive offers a few subtle details that allow us to tell the gas and electric versions apart. Most obviously, this electric supercar devoid of any exhaust tips and features a new “Electric Drive” badge on both its front fenders. The bumpers are also slightly different to the gas versions, particularly the rear one, while the grille and front intakes are painted to match the body color.
The cabin layout remains much the same as the gas-powered versions. One new element is the controller for the AMG Torque Dynamics feature, which offers the choice of Comfort, Sport and Sport Plus modes for the ride and handling.
The new 2012 Mercedes-Benz SLS AMG Coupe Electric Drive Concept has only been announced for the European market. This model will hit Germany dealership in July 2013, price will start from €416,500 (US$536,200 at the current exchange rates), or more than twice the cost of the SLS AMG Coupe €204,680.
