Mission-Ready Chevrolet Colorado ZH2 Fuel Cell Vehicle Breaks Cover at AUSA 2016.

The Colorado ZH2 features an Exportable Power Take-Off unit (EPTO) that allows the fuel cell to power activity away from the vehicle, such as remote locations where electric power may otherwise be unavailable.

GM and the U.S. Army Tank Automotive Research, Development and Engineering Center (TARDEC) collaborated to develop the Colorado ZH2 from contract to concept in less than a year.

GM is leveraging a range of advanced technologies for multiple applications, including military.

“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 of TARDEC. “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.”

The Army will evaluate the ZH2 fuel cell for:

    Near-silent operation enabling silent watch capability
    Reduced acoustic and thermal signatures
    High wheel torque at all speeds via electric drive
    Low fuel consumption across operating range
    Water by-product for field uses

GM and TARDEC have fuel cell development laboratories located 20 miles apart in southeast Michigan. Most of the Colorado ZH2 was assembled in GM’s Advanced Vehicle Integration facility in Warren. Calibration testing at GM’s Milford Proving Ground will continue into early 2017, when the vehicle will be turned over to the Army for a year of field testing.

“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,” said 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.”
