If you're wondering about the future of the automobile you're most likely to find the answer at the leading transportation design schools. One such is Germany's Pforzheim University, where students displayed their work in the school's spring graduate show in February. Business Week offers an article about the display, consisting primarily of a slide show that reveals several of the most interesting concepts. I've chosen one by Vitalis Enns, whose description reads, in part: "Due to the recent success of Renault's Formula 1 team and the absence of a Renault production sports car, this concept is based on sports car philosophies... a sports car for a small family, with a two-person seating configuration and an extra seat for a child. The structural solution is based on lightweight construction methods used in snowboard and bicycle industries, with a parallelogram frame made from wood and fiberglass."
