the name symbolizes the combination of hydrogen as fuel for the fuel cell propulsion system, and the replacement of conventional mechanical and hydraulic control linkages for steering, braking and other control systems by a drive-by-wire system. By combining fuel cell and by-wire technology, General motors have packaged this vehicle in a new way, opening up a new world of chassis architectures and customized bodies for individualized expressions and it is a significant step towards a new kind of automobile that is substantially more friendly to the environment and provides consumers positive benefits in driving dynamics, safety and freedom of individual expression.
The car is derived from GM’s previous concept of a drive-able fuel cell vehicle called the Autonomy which was debuted at the 2002 North American Motor Show in Detroit. GM does not hope to be selling these cars immediately, due to certain unavoidable hindrances but they are optimistic of seeing these vehicles on the road in the next decade or two.

- The big concern with drive-by-wire vehicles is safety. Since there is no physical connection between the driver and the car’s mechanical elements, an electrical failure would mean total loss of control.
- The other major hurdle for this type of car is figuring out energy-efficient methods for producing, transporting and storing hydrogen for the onboard fuel-cell stacks. With the current state of technology, actually producing the hydrogen fuel can generate about as much pollution as using gasoline engines, and storage and distribution systems still have a long way to go.
- Adding adequate crash protection.
