Vying For Army Contract, GM Makes Mil-Spec Version Of Chevy Colorado Pickup

GM Defense has made a prototype version of the Colorado that tosses away the doors so it can hang from a helicopter.

GM Defense creates a Chevy Colorado ISV prototype to compete for a U.S. Army contract.

The US Army is looking to GM for their next infantry-moving vehicle, so they produced a military-spec version of the Chevy Colorado pickup.

We mostly think of the army as tanks and helicopters, but the vast majority of vehicles in the US Army’s arsenal are just regular old people movers. Getting troops from point A to point B is the most important job in the military, which is why the US Army is currently hosting a competition to decide who will make their next Infantry Squad Vehicle.

One of the companies contending for this lucrative contract is GM Defense, the military division of General Motors. Their offering up a militarized version of the Chevy Colorado ZR2 that has been “supplemented with both custom and commercially available parts.” While 70% of the chassis is made using off-the-shelf components, you can plainly see some drastic alterations to the body.

You’ll also definitely notice the complete lack of doors or even a roof. That’s because the army requires that the ISV be "light enough to be sling-loaded from a UH-60 Blackhawk helicopter, compact enough to fit inside a CH-47 Chinook helicopter and versatile enough to carry up to nine soldiers and all of their gear at highway speeds, both on pavement and off-road under extreme conditions." Since doors just add too much weight for a Blackhawk chopper to carry, they get tossed.

What did not get tossed is the ZR2’s suspension. The Colorado ISV uses the same Multimatic DSSV dampers and long-travel rear leaf springs as the civilian version, as well as the same skid plates as the ZR2 Bison.

Interestingly, under the hood of the Colorado ISV is not the 2.5-L Duramax diesel, but a 2.8-L inline 4-cylinder turbo-diesel built by VM Motori, an Italian manufacturer. That engine is used in diesel-equipped Colorados for the export market and is rated for 186 hp and 369 lb-ft of torque. We can only assume that swap was also done for weight and space considerations.

GM is competing against similar entries from Oshkosh/Flyer Defense and SAIC/Polaris for the job of making 650 ISVs by 2020. The US Army will render its decision next March.
