Introduced at the 2003 Detroit Motor Show the GM Hy-Wire
concept was an evolution of the GM
AUTO-nomy concept and was intended to help further
develop both hydrogen fuel cell and drive-by-wire technology.
Like the AUTO-nomy concept the Hy-Wire concept utilized
a modular construction method which placed all the running
gear and fuel cells low down in the vehicle meaning the
layout of the interior floor plan is not dictated by the
shape and location of the engine, transmission and driveshaft
of a more conventional vehicle. This means the passenger
compartment could be designed to better fit the occupants.
Thanks to a drive-by-wire system which eradicates the
need for any direct mechanical linkages to the wheels,
the steering wheel and pedals can be slid from the left
hand side to the right hand side in a matter of seconds
to suit different geographic locations and local road
The hydrogen fuel cell system of the GM Hy-Wire consisted
of 200 individual fuel cells connected in series with
a fuel cell stack located at the rear of the vehicle in-between
the rear wheels.
The fuel cell provided electricity for a front mounted
electric motor which produced 126 horsepower. However
for short periods of time, when extra acceleration is
needed, it can put out up to 173 hp.
