The Chevy Colorado recently won its second consecutive Motor Trend Truck of the Year Award…and it looks like the U.S. Military took notice. The mid-sized pickup is going to see duty with an interesting angle: the Army will be using a Colorado equipped with a hydrogen fuel cell powerplant. The technology, while still new and somewhat untested, has potential for military application. Hydrogen engines are quiet, torquey, and can produce power and water for troops in the field. Will this be a great innovation or a pain in the neck for our mechanics in uniform?
