2014 BMW i 8. When is a supercar not a supercar? When it's a carbon-fiber-bodied, three-cylinder hybrid that aims to rethink how we view speed, mass production, and everything that makes an exotic tick. The proportions are borrowed from BMW's awesome M1, a 1970s flop that waited 30 years for the world to appreciate it. Prediction: This won't take nearly as long. BMW - RoadandTrack.com.
