Cummins Westport Inc. and Cummins India Ltd. Announce Order for 3,125 Natural Gas Engines

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Oct. 15, 2008) - Cummins Westport Inc. and Westport Innovations Inc. (TSX:WPT)((NASDAQ:WPRT) -

Cummins Westport Inc. ("CWI"), a leading provider of high-performance, alternative fuel engines for the global market, and Cummins India Ltd. ("CIL") announced today that the Delhi Transport Corporation ("DTC") has ordered 3,125 natural gas buses equipped with CWI's B Gas Plus engines. The 230 horsepower B Gas Plus engines, powered by compressed natural gas (CNG), are licensed by CWI and manufactured by CIL.

"We are delighted that DTC, already one of the world's leading eco-friendly transit fleets, has selected CWI in their continuing contribution towards cleaning up the environment of the nation's capital in India. This order of over 3,000 engines, our single largest to date, highlights both the quality of our products and our efforts to make our clean burning, natural gas engines available around the world," said Guan Saw, CWI's President. "Our natural gas engines provide significant benefits to consumers facing global concerns around energy security and high fuel prices. The economic benefits are equally matched by the positive environmental benefits by reducing harmful emissions such as particulate matter (PM) and oxides of nitrogen (NOx)."

"We are excited about providing dependable, fuel efficient, environmentally friendly solutions in India. The B Gas Plus engine is a great example of this," said Anant Talaulicar, CIL Chairman and Cummins Vice-President.

According to NGVAmerica, the New Delhi Natural Gas Vehicle Program has halved the air pollution in comparison to ten years ago. Approximately 60,000 auto rickshaws in New Delhi, India were required to convert to compressed natural gas (CNG) for fuel. A decade later, the government has issued a report hailing the success of the program, showing that, while the number of vehicles on the road has doubled, the pollution rate has halved. Outside of New Delhi, ten other major Indian cities also have aggressive natural gas vehicle conversion programs. As a result, the amount of petroleum used in the country has been cut dramatically from projected levels-a significant and cost-saving achievement for a country that has to import 70% of its diesel and gasoline.
