The most green of the concepts is the Volvo Stal Concept, a sports car designed by Carrie Fodor and engineered by Aditya Rajderkar. The Stal (what kind of name is that for a car?) is a lightweight EV that "accommodates the environmentally conscious Generation X consumer". The model is safe, too, with laser-welded blanks to give the body and door panels more strength.
The other two vehicles, called Land Rover Carver and Cadillac Entourage, focus more on using steel in cool ways than in being green. The Entourage, for example, has a strong frame to allow for a glass roof and the vehicle is shaped a little like a boat. The models were unveiled yesterday and will be showcased at the North American International Auto Show in Detroit next January.
