Cummins Westport, DOE, and NREL Partner to Deliver
Next Generation Natural Gas Engine Three Years Ahead
of U.S. Regulations

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - Feb. 9, 2005) - Cummins
Westport Inc. and Westport Innovations Inc. (TSX:WPT)

Cummins Westport Inc., in partnership with the U.S. Department of
Energy's (DOE) National Renewable Energy Laboratory (NREL), today
announced its intent to commercialize an engine for medium-duty truck,
refuse and urban transit markets that meets the stringent 2010 U.S.
Environmental Protection Agency (EPA) emissions standards and 2007
California Air Resources Board (ARB) urban bus standards. Scheduled for
commercial launch in 2007, the engine will be introduced three years
ahead of the EPA emissions deadline.

Cummins Westport will work with NREL to develop a next generation
natural gas engine that meets the 2010 targets without the need for
expensive aftertreatment systems. The advanced engine is also expected
to have improved thermal efficiency and power density relative to
current natural gas engines.

"We are extremely pleased by test results to date with our chosen
technology path and excited at the prospect of offering this solution to
customers well ahead of federal and state regulations," said Hugh Foden,
President of Cummins Westport Inc. "The availability of a high
performance engine with ultra-low emissions bodes well in the fight
against deteriorating urban air quality and climate change. Our solution
should offer significant economic as well as environmental value to
customers."

Cummins Westport and NREL are funding the project under a cost-sharing
contractual agreement, with NREL contributing an initial US$600,000 for
the first year of work that will commence immediately. NREL's
participation over the life of the project is anticipated to be roughly
US$2 million. The project builds on a previous Next Generation Natural
Gas Vehicle (NGNGV) award that Cummins (a partner in the Cummins
Westport joint venture) received to develop and demonstrate advanced
natural gas engine technologies. That project, co-funded by the South
Coast Air Quality Management District, is making progress toward
achieving EPA 2010 emissions levels in the laboratory using low-cost
equipment.

The EPA currently regulates four major pollutants for heavy-duty
applications: oxides of nitrogen (NOx), one of the main precursors to
ozone, particulate matter (PM), non-methane hydrocarbons (NMHC) and
carbon monoxide (CO). In 2007, when new standards for NOx and PM are
introduced, Cummins Westport's advanced natural gas engine will meet the
2010 NOx standards (0.2 grams/brake-horsepower hour), which are 83%
lower than the 2007 phase in provision of the EPA legislation. As with
Cummins Westport's existing spark-ignited natural gas engines, PM
emissions for the new engine will be at or below 2010 levels without a
particulate trap. Greenhouse gas emissions are expected to be at least
17% lower than the cleanest diesel engine available. Carbon monoxide and
NMHC emissions are anticipated to be at or below the 2010 standard.

Cummins Westport Inc., a joint venture of Cummins Inc. (NYSE:CMI) and
Westport Innovations Inc. (TSX:WPT), manufactures and sells the world's
widest range of low-emissions alternative fuel engines for commercial
transportation applications such as trucks and buses. Cummins is a
global power leader in engines, electrical power generation systems and
related technologies. Westport Innovations is the leading developer of
technologies that allow engines to operate on clean-burning fuels such
as natural gas, hydrogen, and hydrogen-enriched natural gas (HCNG).

NREL manages DOE's NGNGV activity in partnership with the South Coast
Air Quality Management District and the California Energy Commission.
The NGNGV activity focuses on development of advanced, commercially
viable medium- and heavy-duty natural gas engines and vehicles that meet
the EPA's approaching emissions regulations for 2007 and 2010. The
ultimate goal is more widespread use of natural gas vehicles, which
would reduce U.S. dependence on imported petroleum.
