General Motors has rolled out a unique variant of its popular midsize Chevrolet Colorado pickup in advance of U.S. military trials scheduled to begin next year.
The Colorado ZH2, seemingly plucked from the set of a Mad Max sequel, has seen its frame and body stretched, reinforced and modified to within an inch of its life, and draws its power from a hydrogen fuel cell.
If this sounds like eco-nonsense, and you’re wondering when the U.S. Navy will announce a return to sail, hold on — there are tactical advantages to the vehicle’s powertrain.
Developed in collaboration with the U.S. Army Tank Automotive Research, Development and Engineering Center (TARDEC), the vehicle went from concept to test model within a year. Naturally, GM is quite proud of this.
The U.S. Army takes possession of the vehicle next year, where “extreme field testing” will give a thumbs up or down to the future use of hydrogen vehicles in military operations.
Riding on a lengthened frame, carried by 37-inch tires and a heavily modified suspension, the ZH2 has an immediate drawback. Simply, hydrogen is an incredibly scarce power source, despite being one of the most common elements on earth. Gasoline, diesel, and even electric power is infinitely easier to find, with infrastructure solidly in place.
It’s easy to scoff at the idea of a hydrogen-fueled vehicle waltzing onto a battlefield filled with flying ordnance, or smirk at the supposed benefits of lowering emissions during messy combat operations. The ZH2, however, isn’t taking the place of a main battle tank or light armored vehicle. It’s a specialized tool, with two big advantages: portable power, and near-silent operation.
Under its hood, the ZH2 packs a Exportable Power Take-Off unit (EPTO) that GM says “allows the fuel cell to power activity away from the vehicle, such as remote locations where electric power may otherwise be unavailable.”
To pass the Army’s test, the ZH2 needs to impress in several areas. On the evaluation checklist are: near-silent operation, reduced acoustic and thermal signatures, high wheel torque, low fuel consumption, and water by-product for field use.
For a specialized mission, the ZH2 would presumably tap into a limited reserve of hydrogen at the operating base, then proceed on its relatively quiet foray into the danger zone.
According to Defense One, the vehicle starts off-road testing in January, rotating through Fort Bragg, Fort Benning, and Quantico. Some technical testing will take place in Michigan.

Where’s the cloaking device?
I can see the benefit of a low heat signature and near silent operation but the question on everyone’s mind and is mentioned obliquely by the author, how much shielding does the fuel supply have? The Hindenburg didn’t fare too well with hydrogen at atmospheric pressure.
love the looks.
You don’t need shielding form IEDs when you _are_ the IED.
VoGo – gives a whole new meaning to the term “suicide mission”.
Trump to North Korea – we have “hydrogen” bombs on wheels ;)
So appears this will be a special ops vehicle for remote locations where secretive observation is required. Ability to generate electricity and water would expand time on station.
LOTS of questions around the engineering but it’s a cool project.

Getting an adequate supply of Hydrogen is the real Achilles heal for this concept. Design looks good though
Everybody panned the Chevy Avalanche and the Honda Ridgeline for looking something like this.
If the Camaro were a CUV…..
Great, now the military can be plagued by the zero visibility shitfest that is moder auto design as well.
You’ve not sat in an M1A1 tank have you?
This’ll never see use in the Big Army but the Special Ops guys should make good use of its silence. With limited refueling options, however, I would anticipate an inordinate number of these get thermited after hitting the objective.
Any idea what transmission it uses?
This looks like something Master Chief would drive.
If they want silent running and low heat signature why not start with a Tesla power pack ?
