Stunning BMW i8 Spyder revealed

This is the BMW i8 Concept Spyder, an open topped hybrid supercar that, despite the 'concept' part of its name, will make production in 2015. It will be nearly as quick as an Audi R8 Spyder, yet more economical than a regular Toyota Prius. Win...win!

The i8 is the halo supercar of BMW's forthcoming 'i' range of clean, green cars; so far, the company has unveiled the i3 city car and i8 coupé, which bookend what will become an entire range of eco cars.
