...steering column and no brake pedal. It requires no gasoline, emits no pollution (just a little water vapor) and yet handles like a high-performance Porsche. It might sound like an environmentalist's fantasy, but there it was on display at the Paris Auto Show last September: the Hy-wire, a politically correct, fully functional prototype that General Motors claims could be road ready by 2010. Other car manufacturers--including Toyota, Honda and Ford--are working on post-fossil-fuel automobiles, but only GM has rethought the car from the ground up, adopting an impressive array of advanced technologies invented...
Eliminating all the mechanical controls frees up the space where an engine would normally reside; in the Hy-wire prototype you can see straight through the front of the car. Without a steering column, designers can place the controls anywhere in the car for maximum comfort and safety--even in the backseat...
...heart of the Hy-wire, however, is the aluminum, skateboard-like chassis that runs the length of the vehicle. Nestled within it are the fuel cells, an electric motor, tanks of compressed hydrogen and all the electronics. Because the fiber-glass body is basically a shell, different models can be swapped like cell-phone covers. So you could in theory drive a sports car on the weekends and change it into a minivan to haul the kids to school...
...course, the Hy-wire is just a prototype, and getting the first production units on the road by 2010 would require the notoriously sluggish auto industry to shift gears a lot faster than usual. For one thing, the roadside infrastructure that fuels and services today's gas guzzlers would have to be redesigned to dispense hydrogen and reprogram faulty control systems. But if the result were a fleet of safe, fuel-efficient, nonpolluting cars and trucks that reduced or eliminated the world's dependence on fossil fuel, it would be worth the effort. --By Anita Hamilton
Researchers at General Motors have shown one of the most innovative approaches to fuel-cell cars with the Hy-wire prototype, unveiled this year. Gone are the engine, transmission and gas tank found in today's internal-combustion cars. In their place is a skateboard-like platform--just 6 in. thick--that houses the fuel cells, the hydrogen tank and all the electronics that are needed to power the car. Electric motors placed inside each wheel get the car rolling. Because the steering controls are all electronic--a concept known as "drive by wire"--gone, too, is the mechanical steering...
