Mercedes Benz SLS AMG E Cell

Some concepts actually make it to production, and one example is the MercedesBenz SLS AMG ECell. Based on the current firebreathing SLS model, the ECell uses four electric motors instead of a gravitydefying V8.

The result is a more ecofriendly car that can get to 60mph in 4 seconds and then on to 155mph. Best of all, all those 525 ponies and 650lb/ft of torque are available from 4,000 revs. Were less sure about the colour, though, which looks like the aftermath of beer and kebab night.
