The Michelin Challenge Design 2006 running in conjunction with the North American International Auto Show in Detroit has some fascinating designs including this one, the Quasar Terragen, a hydrogen electric pickup designed by Tomas Sarnovsky from the Czech Republic. The wheels are designed with the Michelin Tweel, an airless tire design and the pickup bed can be reconfigured for extra space, it has a sort of built in bed extender. Nice thinking, neat design.
