GM Defense is the military product subsidiary of General Motors, and it’s doing some wild things. For example, one of its current projects is the ZH2 hydrogen fuel cell-powered electric truck, based on a Chevrolet Silverado chassis. The concept is to provide a stealthy drive system that lowers the truck’s noise, smell, and thermal signature dramatically while providing extreme off-road capability. Taking that concept further, however, is the Unmanned Ground Vehicle (UGV) concept.
