Mercedes-Benz SLS Electric Drive

found on Top Gear

Guess what's the most powerful AMG on sale? We bet you'll plump for the SLS Black, but you'd be wrong. It's this SLS Electric Drive, with 740bhp and 738lb ft. That's an enormous 118bhp and 270lb ft more than the Black - hardly a slouch when it comes to bare stats. And yet it produces precisely no local CO2 emissions.

So what is it? Bluntly, the SLS ED is possibly the most brilliantly revolutionary thing that the already-bonkers lot at AMG have ever created: a fully electric AWD supercar. It's a serious bit of engineering, too. The ED uses four motors (one for each wheel) connected to two gearboxes, and there are 12 battery modules, most of which are mounted nice and low in the unused space where the transmission tunnel would normally be. The location is key: the batteries weigh a whopping 548kg, so they need to be low down. Mounted as they are and with the car driven carefully, the cells give a theoretical range of 155 miles.

It's a shame to focus on the green and serene engineering of the Electric Drive, though, because its pure, visceral pace is simply extraordinary. I can't think of anything other than perhaps the Veyron that has this tsunami-surge of torque.
