UQM Technologies Receives Order for Additional Motor and Controller Systems From Eaton Corporation for Installation in Hybrid Electric Trucks

FREDERICK, Colo., July 25 -- UQM TECHNOLOGIES, INC. (AMEX:UQM) , a developer of alternative energy technologies, announced today that it has received an order for additional UQM(R) permanent magnet motor and controller systems from Eaton Corporation's Truck Components business unit for integration into Eaton's hybrid electric propulsion systems for trucks and other heavy duty vehicles.

Eaton's heavy duty hybrid propulsion systems are aimed at doubling the fuel efficiency of today's conventional trucks, while maintaining reliability and durability of components and meeting future federal emissions standards for 2007 and beyond.

Most heavy vehicles today are powered by large diesel engines. Hybrid propulsion systems generally consist of a smaller internal combustion engine augmented by an electric drive, an energy storage system and regenerative braking or other energy recapture system. Reliability demands are crucial, as heavy vehicles typically can be driven as much as one million miles over a ten-year period. Heavy vehicles include trucks of various types and uses, buses and numerous off-highway vehicles, including military, construction, farming and mining equipment.

Eaton's Truck Components operation, based in Galesburg, Mich., is a pioneer in hybrid systems for commercial vehicles. Eaton Corporation is a diversified industrial manufacturer with 2004 sales of $9.8 billion. Eaton is a global leader in electrical systems and components for power quality, distribution and control; fluid power systems and services for industrial, mobile and aircraft equipment; intelligent truck drivetrain systems for safety and fuel economy; and automotive engine air management systems, powertrain solutions and specialty controls for performance, fuel economy and safety.
