Raser to Unveil Advanced Series Plug-in-Hybrid Drive System Design at SAE World Congress in Detroit

PROVO, Utah April 10, 2008; Raser Technologies, Inc. announced today it will be unveiling components of a new advanced extended-range plug-in series hybrid electric vehicle powertrain and integrated drive system designed for full-size SUVs and pickup trucks in conjunction with its systems integration partner, FEV, at the Society of Automotive Engineers (SAE) World Congress in Detroit, Michigan April 14-17, 2008. The extended-range plug-in series hybrid architecture integrates Raser’s Symetron™ technology in an advanced 200 kilowatt (kW) peak, 100 kW continuous AC induction motor and power electronic traction drive and a 100 kW PM synchronous generating system and a 700 volt lithium-ion battery and power management system that is expected to enable an average 100 miles per gallon fuel consumption in full-size fleet SUVs and service trucks.

A full-size plug-in series hybrid SUV with this new powertrain is designed to drive 40 miles in all-electric mode under battery power, with near zero emissions. Fleet versions of this extended range electric vehicle are expected to offer up to 50 kW of exportable power from the onboard generator, a highly valued feature by utility and other fleets.

The SAE World Congress is the largest annual gathering of automotive engineers and typically highlights innovative automotive developments that often are incorporated in future production vehicles. The four-day Congress in Detroit is expected to host over 30,000 industry specialists, engineers and business leaders.

“We are honored to be a part of this exciting Congress and to be able to demonstrate what we believe to be the next generation of hybrid electric vehicles. These vehicles offer a realistic pathway to reduced vehicle emissions, independence from imported oil, and cost-effectiveness for the consumer,” said James Spellman, Vice President of Transportation for Raser Technologies. “We are also very pleased to be exhibiting this innovative powertrain and master control system with our development partner on this project, FEV.”

“We admire Raser’s vision and look forward to completing the development of this innovative drive system,” said Dr. Joachim Wolschendorg, vice president, Vehicle and Drivetrain Engineering division and CTO of FEV, Inc. "FEV is uniquely qualified to provide all of the necessary resources to help Raser integrate this advanced technology into products for production."
