Raser Technologies Unveils 100+ MPG Plug-in Hybrid Hummer at the SAE World Congress in Detroit

Technology in New Electric Hummer Could Drive Bold Leap Ahead for U.S.
Automakers, Making Popular Trucks & SUVs `Greener Than a Prius`
DETROIT--(Business Wire)--
Raser Technologies, Inc. (NYSE:RZ) today unveiled a 100+ mpg Hummer H3 powered
by Raser`s plug-in hybrid E-REV (Extended-Range Electric Vehicle) at the 2009
SAE International World Congress, Cobo Center, Detroit, MI.

Raser developed the 100+ mpg Electric H3 demonstration vehicle working closely
with Hummer. Just one year ago at the 2008 SAE World Congress, Raser and its
development partner FEV Inc., Auburn Hills, MI, a leading automotive integrator,
introduced Raser`s E-REV power train, similar in function to the Chevy Volt but
designed for use in a variety of larger full-sized SUVs and light trucks. The
vehicle was developed in association with the Plug-in Hybrid Development
Consortium, co-founded by Raser along with leading electric utilities, lithium
ion battery companies and other automotive technology companies.

Raser CEO Brent M. Cook said, "The technology in this electric-powered Hummer is
a leap ahead for U.S. Automakers. It could make the nation`s popular light
trucks and SUVs greener than a Prius."

The vehicle has performed well in initial test drives and dynamometer testing
conducted by FEV. Video from recent test drives of the 100+mpg H3 is available
online: http://rasertech.com/hummer.

The plug-in electric Hummer H3 has a range of about 400 miles, driving its first
40 miles exclusively on batteries before turning on its combustion generator.
Most vehicles drive fewer than 40 miles a day, most drivers would rarely use gas
and average more than 100 mpg in gas fuel economy over time.

Raser`s E-REV power train was designed for most full-sized 4WD SUVs and light
trucks, which represent nearly half of the vehicles on U.S. roads today because
of their versatility and wide application in fleets.

"We chose the Hummer H3 and H3T as demonstration vehicles because trucks and
SUVs are the best-selling vehicles in America and can benefit the most from
increased fuel economy and reduced emissions," said Cook.

The Electric Hummer H3 is propelled entirely on electricity by Raser`s 200kW
advanced AC induction motor connected to a 4WD transmission. A small high
efficiency EcoTech engine uses Raser`s 100KW electric generator to recharge the
batteries while driving and provides additional electric power when needed.

"Our goal was to demonstrate that electric vehicle technology is a viable
solution for a variety of vehicle platforms," said Gary Rogers, president and
chief executive officer of FEV. "This full-sized SUV extended-range electric
vehicle shows that fuel economy in larger vehicles does not mean sacrificing
power and utility."

The Hummer H3 Extended Range Electric Vehicle is on display in FEV`s booth #1425
at the Cobo Center, from April 20 through Friday, April 24.
