The GM Sequel was the third in a trio of GM concept vehicles
which utilized a hydrogen fuel cell drivetrain. First
came the GM
AUTO-nomy in 2002, and later the Hy-Wire
in 2003. The Sequel concept, which was revealed at the
2005 Detroit Motor Show, was the closest of the three
to a production vehicle.
The drive train of the GM Sequel consisted of a fuel cell
stack at the front, hydrogen storage tanks in the centre,
and lithium ion batteries at the rear. The front wheels
were driven by a single electric motor, while at the back
each rear wheel got its own motor. This setup meant that
the Sequel was a full 4WD vehicle. The power output of
the three motors combined was posted at 148 hp.
Thanks to the compact packaging of the hydrogen fuel cell
drive train and the drive-by-wire control systems the
interior of the GM Sequel concept was spacious and uncluttered.
