Audi shows off its metroproject concept car at the 2007 Tokyo auto show.
Audi's metroproject concept car uses a unique take on the Quattro all-wheel-drive system, with gasoline engine-powered front wheels and electrically driven rear wheels. The car can operate with gas or electric power alone, achieving a range of over 60 miles on the latter. Its infotainment unit can be removed, yet will still control the car through a wireless network. The future is indeed now. Audi showed the metroproject off at the 2007 Tokyo auto show, and we fought through the crowds to get pictures.
