General Motors Corp. and the U.S. Army revealed a diesel hybrid military pickup truck equipped with a five-kilowatt regenerative fuel cell auxiliary power unit (APU) that could become the model for the Army's new fleet of 30,000 light tactical vehicles by the end of the decade. GM unveiled the heavy-duty, militarized version of the commercial Chevrolet Silverado crew cab in a ceremony with Larry Burns, GM vice president of research and development and planning, and U.S. Army Major General N. Ross Thompson III, commanding officer of the Army's Tank-automotive and Armaments Command. According to GM, the diesel hybrid would improve Army fuel consumption by 20 percent over conventional diesels, reduce emissions, and provide troops with clean, reliable electrical power.
