At 6.5 feet tall and more than 7 feet wide, this imposing truck is mighty in its stature. To match its appearance, the suspension is just as rugged. With 37-inch tires and a heavily modified suspension, this truck can climb over just about anything that appears in front of it on the battlefield.

Its looks and size might be what turns heads online, but it was GM's job to not turn any enemy's heads when deployed. To do this, GM has installed a fuel cell to have the truck run on electricity. By doing this, the truck runs almost completely silent and has reduced acoustic and thermal signatures.

“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, in the press release. “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 ZH2 will be tested at GM's Milford Proving Grounds into early 2017 when the truck will be handed off to the Army for further testing.
