LONGMONT, CO--December 4, 2012: Efficient Drivetrains, Inc. (EDI) has selected the UQM Technologies, Inc. (NYSE MKT: UQM) PowerPhase system as the electric drive in its newly-developed Parallel-Series-Electric powertrain system. Development and initial testing of the platform has been completed, and EDI is currently in contract discussions with multiple truck manufacturers and a bus manufacturer to use the system.

“The EDI powertrain is a unique approach to electrifying vehicles, and our range of electric motors and controllers adds to the scalability of the system.”

"This platform demonstrates the viability of our PowerPhase systems in hybrid applications as well as in all-electric vehicles," said Eric R. Ridenour, President and Chief Executive Officer of UQM Technologies, Inc. "The EDI powertrain is a unique approach to electrifying vehicles, and our range of electric motors and controllers adds to the scalability of the system."

The EDI Parallel-Series-Electric system was designed to fit in the space required by a traditional internal combustion engine and transmission, both in front-wheel-drive and rear-wheel-drive applications. This makes it easier to adapt the new Parallel-Series-Electric powertrain to existing vehicles.

"For manufacturers and customers alike, this is one of the most adaptable automatic vehicle drivetrains in the world," said Joerg Ferchau, Co-founder and CEO of EDI. "The UQM PowerPhase system has performed well in our testing, as has the rest of the powertrain, providing efficiency and capability as it switches from pure EV mode to parallel hybrid to series hybrid according to driving conditions."

UQM powers test-fleet vehicles by Audi in Germany, Rolls-Royce and the London Taxi Company in the U.K. UQM is also powering Hino electric city buses in Japan and Holden demonstration vehicles by EV Engineering in Australia. In the U.S., UQM can be found in the CODA all-electric passenger sedan, now available in California, Proterra all-electric composite transit buses, Boulder EV all-electric delivery vans, and Electric Vehicles International all-electric medium-duty trucks and delivery vans.
