UQM Technologies Receives Order From Denver RTD to Retrofit Seven Hybrid Electric Mall Shuttle Buses

FREDERICK, Colo., Aug. 9, 2005 -- UQM TECHNOLOGIES, INC. (AMEX:UQM) , a developer of alternative energy technologies, announced today that it has received an order from the Denver Regional Transportation District ("Denver RTD") for UQM(R) generators and motor controllers to retrofit seven hybrid electric mall shuttle buses. Each 45 foot hybrid electric mall shuttle bus will be retrofitted with a 35 kW UQM(R) generator and two UQM(R) power electronic motor controllers to control the operation of the electric propulsion motors currently installed in each bus.

Denver RTD introduced its hybrid electric fleet of MallRide shuttles in 2000, the first large-scale deployment of hybrid electric buses for transit use in the United States. A total of 36 MallRide shuttles operate on the 16th Street Mall in downtown Denver providing a free ride for passengers across the 1.3-mile long mall connecting Denver Union Station and RTD Civic Center Station for express and regional Denver RTD services.

The hybrid electric MallRide shuttle buses are powered by a compressed natural gas fueled 2.5 liter Ford industrial engine that operates at 2,200 r.p.m. and will turn the UQM(R) generator to produce electricity to recharge the bank of batteries that power the shuttle. The UQM(R) motor controllers feature regenerative braking, a process in which kinetic energy is converted to electrical energy through the braking process and this electrical energy is also used to recharge the battery pack. Each 45 foot MallRide shuttle bus features a low floor design (14 inches above street level) that makes it easier for passengers to step on and off the bus and can transport up to 116 passengers. Last fall, the Company received a contract to retrofit one hybrid electric MallRide shuttle bus, which has been undergoing evaluation in passenger-carrying service on the 16th street mall for three months.

"We are pleased that Denver RTD placed an order for additional UQM(R) generators and motor controllers for use in their hybrid electric MallRide shuttle fleet. Our equipment is well-suited for this demanding application and we are looking forward to additional orders from Denver RTD in the future as their needs require," said William G. Rankin, President and Chief Executive Officer of UQM Technologies, Inc.

Denver RTD is a public agency created in 1969 to operate a public transportation system serving the eight county greater Denver metropolitan area. With an annual operating budget of $331 million, Denver RTD operates a total of 1,074 buses in its 2,326 square mile service area and a light-rail system covering 15.8 miles, boarding over 285,000 passengers weekly.
