General Motors’ military vehicles division, GM Defense, has just begun to deliver a new infantry vehicle to the United States Army, called ISV or Infantry Squad Vehicle, which is based on a conventional model from the American giant; specifically, the Chevrolet Colorado pick-up.
Now, this truck has been converted into a military SUV, capable of transporting nine soldiers, with all their gear. GM Defense will manufacture 649 copies of this new ISV, as part of a contract with the army worth 214.3 million dollars, which is equivalent to about 182 million euros, at the current exchange rate.
There is the possibility, however, that in the next eight years, the United States Army will request an increase in ISV production from GM Defense, to a total of 2,065 vehicles of this type.
Based on Chevrolet Colorado ZR2
According to the manufacturer, this ISV uses many components that General Motors uses in its conventional civilian vehicles, both the Chevrolet Colorado ZR2, with which it shares a base and various elements of Chevrolet Performance. In this case, however, the pick-up cargo box has given way to a greater number of seats and a set of roll bars.
The soul of the vehicle is a Duramax 2.8-liter, turbodiesel, and four-cylinder engine, although GM Defense has not wanted to give figures for power or maximum torque, beyond commenting that it exceeds 190 hp and 500 Nm. The diesel block is associated with a six-speed automatic transmission and a two-speed transfer case.
The system, of course, enjoys a four-wheel drive, with electronically controlled differentials on both axles, while using a suspension with Chevrolet Performance DSSV sports shock absorbers, which are the same as the Colorado ZR2, as well as rear leaf springs from a long travel or hydraulic stops.
Of course, the ISV is packed with skid plates to preserve the model’s most important and vital mechanical components. There is, for example, a front steel panel, in addition to others for the crankcase, the transfer case, the fuel tank, the rear differential, or the rear shock absorber mounts.
Despite everything, GM Defense assures that the ISV is light enough (they have not specified any figure) to be transported by a UH-60 Blackhawk helicopter, and it is also wide enough to fit inside a CH-47 helicopter Chinook.
