Mercedes becomes the first mainstream auto maker to launch a full electric super car with the 2014 Mercedes SLS Electric. Based on the normal, petrol-powered SLS with almost identical visual features, the SLS Electric Drive is powered by four electric motors that generate a total of 740 hp and 737 lb-ft of torque. That makes is faster the V8 model.

There are negative points of course. The battery pack for this system is pretty heavy, for instance, and a full charge takes 20 hours to complete. Still, the performance seems pretty convincing:

Refresher: Thanks to the transmission setup,the SLS ED is equipped with 15.8-inch front and 14.2-inch rear ceramic composite disc brakes. In case you were worried about the added weight from the electric components, worry not — the electric motors weigh just 99 lbs, the monocoque is crafted from carbon-fiber reinforced plastic, and the body is made of aluminum. Total output stands at 740 hp and 737 lb-ft of torque, meaning that 0-62 mph is accomplished in a scant 3.9 seconds. Top speed is electronically limited to 155 mph; driving range is estimated to come in at around 155 miles on a full charge.
