News Release: Cummins Westport recognized for contribution to natural gas vehicles

Cummins Westport Inc., a joint venture between Cummins Inc. (NYSE:CUM) of Columbus, Indiana, and Westport Innovations Inc. (TSX:WPT) of Vancouver, has been recognized with an achievement award by the Washington D.C.-based Natural Gas Vehicle Coalition. California refuse hauler Norcal Waste Systems, which is field testing the 15-liter 400 horsepower Cummins Westport ISXG natural gas engine in fourteen trucks, was also given an award. The NGV Coalition represents more than 180 natural gas companies, engine, vehicle and equipment manufacturers and service providers, as well as environmental groups and government organizations. Achievement awards are given annually to those who have made an outstanding and measurable contribution in the past year to advancing natural gas as a vehicular fuel.

NGV coalition President, Richard Kolodziej, speaking at the World Natural Gas Vehicle conference said Cummins Westport has emerged as a powerful leader in natural gas engine technology. "Cummins Westport's dedication to advanced natural gas engine technology and commitment to the natural gas vehicle industry has made it a cornerstone of the NGV industry," he said. "CWI introduced the C Gas Plus in June 2001, and already more than 1,000 are in service or on order by major transit bus fleets across the U.S., including Boston, Atlanta, Washington D.C., Fort Worth, Phoenix, San Diego and Los Angeles."

Mr. Kolodziej said Norcal has placed 14 innovative liquefied natural gas (LNG) heavy-duty trucks into service since August 2001 as part of a field test of Cummins Westport's ISXG natural gas engines and would take delivery of another nine next year. It had also invested in the construction of San Francisco's first LNG refueling station.

The 400-500 horsepower ISXG, which is the first engine to use a proprietary technology involving the high pressure direct injection of natural gas, matches the power and fuel efficiency of a diesel engine, but with significantly lower emissions. It will go into pre-production in 2003, with full production scheduled for early in 2004.

Others to receive this year's award include Ford Motor Company, the Natural Resources Defense Council, the Sierra Club, Los Angeles Metropolitan Transportation Authority and Manhattan Beer Distributors.

Cummins Inc. is a global power leader in engines, electrical power generation systems and related technologies. Westport Innovations is the leading developer of natural gas fuel systems for diesel engines. Cummins Westport, formed in 2001, develops and markets low-emissions alternative fuel engines manufactured by Cummins.
