Chevrolet Brings Colorado ZR2–Based Infantry Squad Vehicle to the 2019 SEMA Show
Military Light Transport Could See Active Duty Next Year
General Motors brought a unique machine to the 2019 SEMA Show, the Chevrolet Colorado ZR2-based Infantry Squad Vehicle (ISV) prototype. GM was awarded $1 million to create development mules for the ISV—alongside Oshkosh Defense and Flyer Defense LLC, and SAIC and Polaris—for consideration for a U.S. Army production contract next year.
The General Motors ISV is all but unrecognizable as a Chevy product, featuring stripped-down bodywork and an ATV-like interior with nine individual seats: two in the front, three in the back, and four additional posts in what would have been a bed. In fact, the ISV only uses the basic platform from the Colorado, mounting a unique passenger and cargo superstructure to that. The ISV is powered by a 2.8L Duramax I-4 and six-speed automatic transmission, producing 186 hp in this iteration.
Helping keep costs down, GM's ISV utilizes 70 percent off-the-shelf parts, making it easier to produce since the company already builds the Colorado ZR2. Chevrolet Performance developed the ISV's long-travel Multimatic DSSV dampers, long-travel rear leaf springs, jounce shocks, front upper control arms, heavy-duty driveshaft, underbody skidplates, and half shafts. Most of those parts are available either on the ZR2 Bison or as part of the Chevy's ZR2 racing program.
According to GM, the U.S. Army's ISV must be light enough to be sling-loaded into a UH-60 Blackhawk helicopter, compact enough to fit into a CH-47 Chinook Helicopter, and capable of traveling at highway speeds on pavement with nine passengers and their gear. Obviously, it must also be capable off-road.
GM Defense will go up against Oshkosh and Flyer's offering and SAIC and Polaris' offering when the military takes possession of the prototypes November 13. They will then enter validation testing in Fort Bragg, North Carolina, by U.S. Army soldiers in January. Using the manufacturers' production proposals and feedback from the soldiers, the Army will choose one vehicle to go into production in the second quarter of 2020.
