IMPCO: First Choice for Automotive OEMs in Australia

CERRITOS, Calif., June 30 -- IMPCO Technologies, Inc. , has proven its mettle and its technology in the first Propane Challenge Clean Air Rally by supplying fuel product and systems to all entrants.

A group of Mitsubishi, Toyota, Ford and GM Holden motorcars completed the inaugural Propane Challenge Clean Air Rally; a 1500-kilometer journey through regional towns in South Australia and Victoria.

All Australian vehicle manufacturers participated in the event showcasing their unique and distinctive models, with only one thing in common: All OEMs used IMPCO fuel systems and/or products supplied by IMPCO Australia Pty.

Ms. Pearl Kamdar, IMPCO's Director of Asia Pacific Operations stated, "Australia is in the forefront of nations attacking the problem of increasing air pollution by using clean burning gaseous fuels. The use of clean burning gaseous fuels such as propane and natural gas (CNG) provides a major advantage for any country seeking to reduce air pollution, while using indigenous fuels. Mexico, South American countries, China and India have all become aware of the need to improve air quality by reducing exhaust emissions, and all of these countries have turned to IMPCO to help them with technologies, infrastructure and policy-making aimed at enhancing the quality of life for everyone." Ms. Kamdar noted, "There are over 550,000 vehicles operating on propane and CNG in Australia. The price of propane and CNG in Australia is 25-35% the price of petrol."
