Four Hybrid Electric HMMWVs Powered By UQM(R) Permanent Magnet Propulsion Systems Successfully Complete Evaluation Testing

Fourteen Month Evaluation Period Included Extensive Testing by Army Test Personnel at Multiple Sites Including the Army's Aberdeen Proving Ground, Yuma Proving Grounds and the Cold Regions Test Center; Vehicles Under Test Accumulated Over 6,000 Miles of Road Course Testing and More Than 600 Hours of Off-Board Power Generation Testing

FREDERICK, Colo., Sept. 29 -- UQM Technologies, Inc. (AMEX:UQM) , a developer of alternative energy technologies, announced today the recent successful completion of test and evaluations of a fleet of four XM1124 Hybrid Electric High Mobility Multi-purpose Wheeled Vehicles (HE HMMWV) produced by PEI Electronics, Inc., a wholly-owned subsidiary of Integrated Defense Technologies, Inc. , under subcontract to AM General Corporation, the prime contractor for the HMMWV, and the Program Manager for Light Tactical Vehicles at the Army's Tank Automotive and Armaments Command. IDT-PEI built and supported the hybrid electric vehicles throughout the period of the demonstrations and evaluations. These early design vehicles were extensively tested by Army test personnel in arduous environments during the 14 month evaluation period at multiple sites including the Army's Aberdeen Proving Ground, Yuma Proving Grounds, and at the Cold Region Test Center near Delta Junction, Alaska.

The four XM1124 HE HMMWVs are each powered by two UQM(R) propulsion systems, one driving each axle, and a UQM(R) generator.

The testing represented the first controlled and autonomous field testing ever conducted by the Army on multiple hybrid electric vehicles without direct industry involvement. Accumulating over 6,000 miles of road course testing and more than 600 hours of off-board power generation testing, the vehicles collectively met all of the Government's key operating parameters and objectives that were defined for this phase of testing including: (1) Fuel efficiency performance improvements of greater than 30% over the conventional vehicle (48% improvement demonstrated across the Operational Mission Profile at Gross Vehicle Weight); (2) The generation and exportation of 30kW of mobile electric power directly from the vehicles (75 kWatts capable); and (3) C-130 aircraft compatibility with a standard Army shelter installed as a payload. The vehicles have now concluded their pre-SDD phase of operations and one of the vehicles has been transferred to Ft. Benning for additional field evaluations by troops during training procedures. Two other XM1124's have been manufactured and delivered for evaluation by the Army's Aviation Ground Support Equipment community and the Air Force Research Lab in support of their Active Denial System Advanced Concept Technology Demonstrator program.

"The successful completion of this rigorous testing protocol attests to the rugged design of our permanent magnet propulsion systems," said William G. Rankin, President and Chief Executive Officer of UQM Technologies, Inc. "We are pleased to be partnered with Integrated Defense Technologies who, over the course of our multi-year collaboration, has played a critical leadership role in the nurturing and development of hybrid electric technology for application in military platforms."

"Successful completion of this testing marks a major milestone for IDT-PEI's HE HMMWV platforms," said Gary Smith, President of IDT-PEI. "Possibly of greater importance, however, is the technological maturity these pre-SDD vehicles demonstrated to Army testers at multiple sites and across a wide range of operational conditions. Using largely "off the shelf" hardware solutions including PEI's system controls and motor technology from UQM Technologies the HE HMMWV's performed beyond expectations for this early phase of development. With the successful completion of these tests, it is now clear that the Army can leverage hybrid electric technology not only for advanced power trains and their fuel economy benefits, but also as mobile power and energy management systems for current and next generation weapon and support system requirements. There remains more to accomplish in an SDD phase of the program, but clearly the HE HMMWV will move forward as a high maturity, low risk program -- one that will itself serve as a major risk reduction to the Army's Future Combat System."
