Westport Reports Third Fiscal 2006 Quarter Results and 30% Revenue Increase Year to Date

VANCOUVER, British Columbia--Feb. 9, 2006--Westport Innovations Inc. (TSX:WPT), a leading developer of environmental technologies that allow engines to operate on clean-burning gaseous fuels, today reported its third quarter financial results for the three and nine month periods ended December 31, 2005, and provided an update on business operations.

Westport's loss for the three months ended December 31, 2005 was $3.6 million, or $0.05 per share, a 13% improvement from the same period last year. Consolidated revenues were $8.6 million compared to $9.2 million for the third quarter last year. For the nine months ended December 31, 2005, net loss was $13.1 million, a 22% improvement from the prior year's loss of $16.9 million with loss per share of $0.18 and $0.25 respectively. Consolidated revenues for the same period were $31.4 million, a 30% increase over the prior year period. Product revenue rose 24% and parts revenue increased by 46%.

During the third quarter, better warranty claims experience than anticipated in Cummins Westport Inc. (CWI) and lower amortisation and depreciation compensated for the slightly lower sales volume. Quarterly sales volumes are volatile and dependant on the timing of major engine shipments. For the three months ended December 31, 2005, net research and development expenses decreased by $1.1 million primarily as a result of increased government and partner funding of R&D programs. Sales and marketing expenses increased by $0.9 million as several global marketing initiatives continue to develop.

Cash used in operations before changes in working capital was $2.2 million for the quarter and $6.7 million year to date, up $0.1 million from the same period last year but $3.8 million better year to date. Cash and short term investments as of December 31, 2005 totalled $11.5 million.

"We are pleased with CWI's sales growth year to date, which is better than our goal of 20% annual revenue growth in US dollar terms. While our quarterly results will be volatile from quarter to quarter, CWI products have shown steady improvements in quality and increasing market penetration around the world," said David Demers, Westport's Chief Executive Officer. "With CWI's recent launch of production in India with Cummins India Ltd., and the recent conclusion of a similar production agreement with Dongfeng Cummins Engine Company Ltd. in China, CWI is now positioned to move into the largest potential markets in the world with lower cost, locally assembled products. We expect continued strong growth as high oil prices, an ever-increasing focus on urban air pollution and climate change draw new customers to the demonstrated benefits of natural gas vehicles."

"We are also continuing to improve bottom line performance year over year while still making strategic investments in new products, technologies and markets," added Mr. Demers. "To fund commercialisation, we will continue to look for industry, strategic partner, and government funding to finance operations. If needed, we also have the option of realising gains on some of our non-core assets. We are excited by our business progress over the last three quarters and are positioning ourselves to capitalize on several near-term opportunities for growth, including our LNG tank joint venture with Beijing Tianhai Industry Co. and large scale demonstration projects."

Business Programs Update - Third Quarter 2006

Cummins Westport Inc.

Cummins Westport continues to execute on its strategy of maintaining a leading position in environmental leadership and product quality. Lower overall cost of ownership is emerging as the primary reason for shifting to natural gas as a fuel for commercial fleets. To effectively compete in India and China, local manufacturing through local alliances has been the primary strategy.

In China, Cummins Westport finalised its agreement with Dongfeng Cummins Engine Company (DCEC) to manufacture Cummins Westport B-series engines which will be jointly marketed and sold. Under CWI's agreement, DCEC will manufacture engines for CWI for resale in China, but will also supply its other parent, Dongfeng Motors, with this natural gas engine. Dongfeng Motors was ranked the largest manufacturer of heavy-duty trucks and buses in China in 2005.

In India, with Cummins India Ltd. (CIL), the manufacturing launch in January marks the start of production of B Gas International engines by CIL with natural gas-specific components from Cummins Westport. CIL will market the engines in India to Tata, the largest manufacturer of buses in that market.

Local manufacturing will also allow CWI and its partners to build a base for potentially exporting from India and China to price-sensitive, developing regions.

On the quality and emissions side, a Cummins Westport-powered bus won two awards in Russia for "Best City Bus" and "Development of Ecological Transport" at the Moscow International Motor Show.

Cummins Westport recently signed a contract with Utilization Technology Development, with program management and research by Gas Technology Institute, for US$350,000 for demonstration of the advanced Cummins Westport ISL G natural gas engine. The ISL G will meet US Environmental Protection Agency (EPA) and California Air Resources Board (CARB) 2010 emissions regulations at launch in 2007, while also improving fuel efficiency and carbon dioxide emissions.

Other Program Highlights

During the third quarter, Westport made significant progress on several new initiatives outside its CWI joint venture.

"With high oil prices, energy security concerns, and environmental issues appearing almost daily on the front pages of newspapers around the world, we are seeing increasing market readiness for our products from Australia to Asia to North America," noted Mr. Demers. "Governments and industry partners are encouraging us to enter their markets with our High Pressure Direct Injection (HPDI) and HPDI-related products, and we are excited about our ongoing initiatives as we approach a new fiscal year."

"We hope to soon be producing new LNG tanks with our joint venture with Beijing Tianhai Industry Co. Ltd. (BTIC), which will be our first intellectual property licensing arrangement in China," said Dr. Michael Gallagher, Westport's President and Chief Operating Officer. "Market feasibility studies for heavy-duty natural gas engines and our Green Corridor infrastructure development plans are also advancing. We remain excited about the long term potential for natural gas as a key transportation fuel for Asia as it works to reduce dependence on imported oil."

In addition to its activities in China, Westport continued on its path to commercialisation by advancing negotiations with Isuzu Motors of Japan and Energy Developments Ltd. of Australia:

- Westport signed a $1.5 million, 1 year development agreement with Isuzu. With Isuzu funding the development work and committing increased resources to the program, Westport and Isuzu expect to deepen their working relationship in this phase of the agreement and to begin discussions on an Intellectual Property Rights framework in the first quarter of 2006 which would form the basis of future commercial agreements.

- Energy Developments Limited (EDL or ENE) agreed to fund a formal joint business plan for the commercialisation of an LNG mine truck retrofit product using Westport's High Pressure Direct Injection (HPDI) technology. The proposed program forms part of EDL's plans for expanding LNG production and distribution in Australia and is expected to reach a go-no-go position in the first calendar quarter of 2006. If approved, EDL and Westport would enter into an agreement to develop, manufacture, and sell LNG retrofit engine kits to Australian mine customers.

In the quarter, Westport also announced significant technology advancements:

- Westport announced its participation in the $12.2 million Integrated Waste Hydrogen Utilization Project in which, along with a consortium of Vancouver-based industry partners, Westport will be converting and showcasing four public transit buses running on hydrogen and compressed natural gas blended fuel. The project will be funded by Sustainable Development Technology Canada, the Hydrogen Early Adopters program, and Natural Resources Canada.

- The City of San Francisco and Norcal Waste Systems Inc., the city's refuse collection, recycling, and transfer company, committed to demonstrating and deploying Westport's most advanced natural gas technology for heavy-duty trucks through to 2011. Goals of the program include improving combustion and reducing greenhouse gas emissions through the upgrade of three of the current 13 patented HPDI trucks to Westport's second generation technology. This latest technology is also being demonstrated in Canada along the Highway 401 corridor where five patented HPDI trucks have already logged almost 500,000 kilometres since their launch last May.

More recently, Westport and Ford Motor Company announced a project to develop and demonstrate an advanced direct injection fuel system for vehicles powered by high-efficiency, high performance engines operating on pure hydrogen. The two-year development program will be divided into two phases. Phase one will define advanced fuel system requirements including the design of fuel injectors. Phase two will incorporate the design and manufacture of new prototype fuel systems. The Government of Canada will contribute up to $250,000 during phase one and the project will include participation from the US Department of Energy Pacific Northwest National Laboratory.

"Westport's technologies and products can provide a near term solution for the world's energy and environmental issues. We are working hard with companies like BTIC, Isuzu, and EDL to lower our total solution costs and to provide an end to end solution for our customers," concluded Dr. Gallagher.
