UQM Hybrid Electric Propulsion System on U.S. Army Future Heavy Truck Demonstrator

FREDERICK, Colo., Sept. 27 -- UQM TECHNOLOGIES, INC. (AMEX:UQM) , a developer of alternative energy technologies, announced today that it has been selected by Stewart & Stevenson Services, Inc. to provide a UQM(R) hybrid electric propulsion system for use on a U.S. Army future heavy truck demonstrator. The custom UQM(R) hybrid electric propulsion system is being provided in support of the Stewart & Stevenson Tactical Vehicle Systems, LP (TVS) recently announced contract award to develop a prototype as part of the U.S. Army's evaluation of a next generation tactical wheeled vehicle.

The Stewart & Stevenson contract, which is part of the Army's Future Tactical Truck System (FTTS) effort, extends the current National Automotive Center's Maneuver Sustainment Vehicle (MSV) modeling and simulation program to prototype stage. The FTTS is being built to support Future Force units equipped with the Future Combat Systems (FCS). The MSV program will allow the U.S. Army to evaluate the need and performance requirements for a future tactical vehicle that eventually could satisfy both the heavy and medium fleet.

Chris Chambers, Vice President Medium & Future Systems at TVS said, "Our award reflects a high level of confidence in TVS' product design and development skills across the tactical vehicle spectrum, as well as those of UQM Technologies and our other supplier partners. Lessons derived from conducting this demonstrator phase will be integrated with our Family of Medium Tactical Vehicles (FMTV) enhancement program -- the FMTV A2 -- to ensure the U.S. Army continues to operate the most advanced tactical truck fleet in the world."

"We are pleased to be part of the Stewart & Stevenson TVS team win and to have the opportunity to provide an advanced UQM(R) hybrid electric propulsion system as part of the US Army's Future Tactical Truck System program," said William G. Rankin, President and Chief Executive Officer of UQM Technologies, Inc. "We have incorporated a number of recent technology advancements into our proprietary permanent magnet motor and controller systems that have further improved their performance, power density and efficiency, as well as their reliability, durability and cost. The advantages of our systems are being recognized in a number of military vehicle applications, which we believe represents an important and growing market for the Company."
