BMW i3 sheds its skin, shows off carbon skeleton

Want to know how the BMW i3 electric car can be so light (2,800 pounds) despite hauling around a massively heavy battery pack? A lot of it has to do with its carbon chassis. BMW uses something called CFRP (carbon fiber reinforced plastic) to create a material that is light, strong and, crucially, cheap enough to actually be used in production. The car is still on track for its 2013 release, where it will be sold out of posh i Stores like the one recently opened in London.
