After introducing the SLS AMG last year, Mercedes-Benz announced that it was developing a battery electric version of the supercar. The prototype is now ready to be shown to the world. The SLS E-Cell is propelled by a quartet of electric motors with the pair at each axle, integrated with reduction gears to drive all four wheels. Combined, these motors can produce 526 horsepower, sufficient to push the coupe to 60 mph in just four seconds.
The lithium polymer batteries are split between the center tunnel and a box mounted behind the cockpit. Two separate cooling circuits can manage the temperature of the battery packs and related power electronics by either heating or cooling the units as needed. The E-Cell is expected to go on sale in 2013.
