General Motors Hy-wire
The Hy-wire (Hydrogen drive-by-wire) is a concept car from General Motors originally introduced in January 2002. The car runs on hydrogen fuel cells and uses a drive-by-wire system, meaning that the car is controlled electronically. GM asked school children to name the car, and one of them suggested "Hy-wire".
In 2003, General Motors stated that it was confident that it could produce a commercially viable model by 2010.〔
==Design==
Due to hydrogen fuel cell drive system used by the Hy-wire, the conventional car layout has been revamped. Without the need for a conventional engine block and transmission system coupled to the steering column and pedals through mechanical linkage, the car's power system and single electric motor are built into a flat skateboard configuration. This serves to lower the car's center of gravity, but more importantly to standardize vehicle drive train systems. Because all propulsion and energy storage systems are housed in the skateboard, designers are free to arrange the passenger compartment however they see fit. This allows for highly flexible modular vehicle configurations such as a 4 door sedan, mini van, or even a small bus to be placed on the same drive system, with the only difference being the shape of the car's upper body and the location of seats. The skateboard itself contains crumple zones similar to those in conventional automobiles.
