Chevy Colorado ZH2 FCV
Chevrolet has unveiled the most extreme
off-road-capable fuel-cell-powered vehicle ever from GM, set to commence
military field testing in 2017. The Colorado ZH2 stands more than 6 and a half
feet tall (198 cm) and more than seven feet wide, or 203 cm. In order to
achieve these measurements, Chevrolet used a stretched midsize pickup chassis,
reinforced inside and out.
In order to climb over and descend practically all
types of terrain, the ZH2 rides on 37" tires and utilizes a specially
modified suspension that's sure to be put to the test by the US Army - looking
to determine the viability of hydrogen-powered vehicles on military missions.
Speaking of military missions, the Colorado ZH2 uses
an Exportable Power Take-Off unit (EPTO) that allows the fuel cell to power
activity away from the vehicle, which can come in handy in remote locations
where electric power may be unavailable.
"The speed with which innovative ideas can be
demonstrated and assessed is why relationships with industry are so important
to the Army," said Paul Rogers, director at TARDEC (Tank Automotive
Research, Development & Engineering Center). "Fuel cells have the
potential to expand the capabilities of Army vehicles significantly through
quiet operation, exportable power and solid torque performance, all advances
that drove us to investigate this technology further."
Once testing commences for the ZH2, the army will
need to evaluate the vehicle's near-silent operation capability, reduced
acoustic and thermal signatures, the high-wheel torque at all speeds via its
electric drive and its low fuel consumption across its operating range.
"The Colorado ZH2 is a terrific example of GM's
engineering and design skill in creating an off-road vehicle relevant to a
range of potential users," added Charlie Freese, executive director of GM
Global Fuel Cell Activities. "Over the next year, we expect to learn from
the Army the limits of what a fuel cell propulsion system can do when really
put to the test."
