Westport Receives 2007 U.S. EPA and CARB Certification of Heavy-Duty LNG Class 8 Truck Engine

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 4, 2007) - Westport Innovations Inc. (TSX:WPT), a global leader in gaseous-fuelled power technologies, has received California Air Resources Board (CARB) and U.S. Environmental Protection Agency (EPA) certification for its High Pressure Direct Injection (HPDI) technology adapted to the 2007 Cummins ISX heavy-duty engine. The EPA certification and the Executive Order from CARB certifies the HPDI LNG (liquefied natural gas) fuel system to 0.8g/bhp-hr oxides of nitrogen (NOx) and 0.01g/bhp-hr Particulate Matter (PM).

"This certification is testimony to Westport's continued leadership in exceeding North America's toughest emissions standards while providing our customers with the power, efficiency and reliability they demand in a heavy-duty truck engine. The new engine has one-third lower NOx emissions than required by current standards and also demonstrates a significant reduction in greenhouse gas emissions," said Westport President and Chief Operating Officer Michael Gallagher.

CARB and EPA certification will provide further impetus to the plans of the Port of Los Angeles and the Port of Long Beach to replace many of the 16,800 heavy-duty trucks currently operating daily at the Ports with the Westport LNG engine and fuel system. Gallagher stated, "We are now in position with this new engine to support the deployment of these LNG trucks over the next few years to meet Port and other customer interest." Funding was approved 8 weeks ago for the first 158 of the new LNG vehicles.

John Wall, Vice President and Chief Technical Officer of Cummins Inc., added, "We are very pleased to have supported this technology partnership with Westport to achieve this important advancement in the adaptation of the HPDI LNG system to the Cummins ISX engine. This latest step with Westport's unique LNG fuel system and proprietary injector technology continues to demonstrate the capability of HPDI direct gas injection technology to deliver diesel-like performance and efficiency with natural gas as a fuel."

Earlier in November, the Los Angeles and Long Beach Boards of Harbor Commissioners also voted to ban the oldest, dirtiest trucks from the Port of Los Angeles and Port of Long Beach, separately approving a tariff that will gradually limit access to all but the cleanest vehicles and reduce pollution by short-haul vehicles by 80 percent.

LNG fuelling infrastructure to support the new trucks is now under construction. "With the opening this month of the first of our three planned LNG truck fuelling stations for the Ports' initiative, and the completion of our California LNG production plant in 2008, Clean Energy is well-positioned to support the fuelling infrastructure needs of the goods movement industry in Southern California," said Andrew J. Littlefair, Westport Innovations director and CEO of Clean Energy Fuels Corp.

About Westport's LNG System for Heavy Duty Trucks

Westport's liquefied natural gas (LNG) system for heavy-duty trucks offers class-leading emissions, including lower greenhouse gas emissions than comparable diesel engines, and allows trucking fleets to move to lower-cost, domestically available natural gas and/or biogas. Based on the industry-leading Cummins ISX diesel engine with cooled EGR, the LNG version of the engine offers the same horsepower, torque, and efficiency as the base diesel engine rating it is replacing. The Cummins ISX unique dual overhead cam design delivers high performance and exceptional braking every mile. Variable Geometry Turbocharging produces quicker throttle response with less turbo "lag" for faster acceleration off the line and on highway on-ramps. Infinite adjustment provides the exact amount of boost needed at every engine speed.

Currently offered in the Kenworth T-800 and available for delivery in late 2007, the 2007 Westport LNG system is available with 400 and 450 horsepower ratings and up to 1,750 lb-ft torque for heavy-duty port, goods distribution and other commercial truck applications. LNG fuel tanks can be configured to suit customer range requirements. Trucks are eligible for a federal tax credits in the United States and may be eligible for other state-specific emissions credits.
