The Colorado ZH2 fuel cell vehicle will undergo extreme military testing in 2017.

Standing more than 6½ feet tall and more than seven feet wide, the Colorado ZH2 is the most extreme off-road-capable fuel-cell-powered electric vehicle ever from General Motors.

Reinforced inside and out, the ZH2 rides on 37-inch tires and a specially modified suspension that helps the vehicle climb over and descend all manner of terrain.

The U.S. Army will test the Colorado ZH2 in extreme field conditions next year to determine the viability of hydrogen-powered vehicles on military missions.

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