The Chevrolet Colorado midsize pickup has been selected by the United States Army to undergo testing for hydrogen-fuel cell function in the field. Engineers from General Motors and the Army’s Tank Automotive Research, Development and Engineering Center in Michigan are modifying the truck for a 12-month test to evaluate the fuel cell’s performance under “punishing” military duty, reports industry journal Automotive News. Fuel-cell vehicles offer certain over internal combustion, such as developing strong low-speed torque and generating electricity in the field, while water from the tailpipe (the only emission) can be used in dry climates. Their near silent operation is also ideal, especially in combat situations, said TARDEC director, Paul Rogers. The potential capabilities of fuel cells are “extraordinary,” Rogers said.
