UQM Technologies Delivers Hybrid Electric Vehicle to Deere & Company

John Deere Vehicle is the First to Utilize UQM's 10 to 1 Constant Power Speed Ratio and Full Wave Commutation Technologies in the Same Vehicle

FREDERICK, Colo., March 1 -- UQM TECHNOLOGIES, INC. (AMEX:UQM) , a developer of alternative energy technologies, announced today that it has delivered to Deere & Company a John Deere hybrid electric concept vehicle incorporating both of the latest advancements to UQM(R) propulsion system technology, 10 to 1 constant power speed ratio and full wave commutation technology.

Constant power speed ratio (CPSR) is the ratio between the top speed of a motor and its base speed. Across this speed range, a motor is able to deliver maximum power. The Company's permanent magnet electric propulsion systems achieve a 10 to 1 CPSR. UQM(R) propulsion systems incorporating the proprietary 10 to 1 CPSR technology deliver both high torque and high speed capability in the same machine at levels greater than twice that of the industry's next best performing motor technology. Conventional vehicles achieve the high torque required for launch and low end acceleration and the constant power required for high road speed by using a transmission and multiple gear changes.

Full wave commutation is a proprietary method of electronically controlling a permanent magnet propulsion system developed by the Company last year that increases the peak power output of the Company's motors by 33 percent, continuous power output by 10 percent, and improves system efficiency from two to eight percent depending on the operating point.

"The delivery of this John Deere hybrid electric vehicle represents a new level of performance for UQM's electric propulsion technology. By incorporating both of these proprietary technologies in one vehicle, we are able to achieve unparalleled acceleration, top speed and efficiency, while eliminating the conventional transmission. We are extremely excited about the potential for these proprietary technologies in the emerging market for hybrid electric vehicles, particularly for large vehicles in the over-the-road truck, agricultural, construction, mining and military market segments," said William G. Rankin, President and Chief Executive Officer of UQM Technologies, Inc.

"We are excited about the performance of our hybrid electric vehicle incorporating these two proprietary UQM(R) technologies," said Bernard B. Poore, John Deere's Manager, Product Technology. "Throughout our longstanding development partnership with UQM Technologies, we have come to expect, and UQM has delivered, exceptional performance and energy efficiency in a wide range of John Deere concept vehicle platforms."

UQM Technologies, Inc. is a developer and manufacturer of power dense, high efficiency electric motors, generators and power electronic controllers for the automotive, aerospace, medical, military and industrial markets. A major emphasis of the Company is developing products for the alternative energy technologies sector including propulsion systems for electric, hybrid electric and fuel cell electric vehicles, 42-volt under-the-hood power accessories and other vehicle auxiliaries and distributed power generation applications.
