As engineers strive to devise and refine alternative powerplants for cars and trucks, ones that won't burn fossil fuels or make each vehicle a point source of pollution, some are looking to the past for inspiration. One such approach, the electric hub motor, seems to show promise. The idea is to build an electric motor right into the wheel. In fact, Ferdinand Porsche, founder of the famed German auto company, mounted a pair of hub motors that used electricity from a gas-powered generator on a car back in 1900. The car, the Lohner-Porsche, could hit speeds of up to 35 mph, letting it set several world speed records. Hub motors have been around for more than a century, and the fact they haven't caught on speaks for itself. At least that's the feeling of one researcher at an organization dedicated to electric vehicles. As a rule, designers try to minimize unsprung weight to improve handling and steering.
