Cummins Westport receives natural gas bus engine order for Phoenix

    VANCOUVER, June 7 - Cummins Inc. of Columbus,
Indiana and Westport Innovations Inc. of Vancouver, British Columbia
announced today that their Cummins Westport Inc. joint venture has received an
order for 100 natural gas transit bus engines for Valley Metro, the public
transit entity for the Phoenix, Arizona metropolitan area.

    The Cummins Westport engine for these buses will be the newly developed
C8.3G Plus, an 8.3-litre, spark-ignited engine rated at 280 horsepower. The
engines will be installed in new buses to be manufactured by North American
Bus Industries of Anniston, Alabama. Delivery of the buses is scheduled to
take place from October 2001 through February 2002.

    "The selection by Phoenix of natural gas for public transit buses
underscores the low-emissions and fuel price advantages of this fuel," said
Glenn Kelly, Equipment Analyst, City of Phoenix Public Transit Department. He
noted that Phoenix began operating natural gas buses in 1998 under an Arizona
mandate to reduce emissions through the use of alternative fuels.

    Valley Metro currently has approximately 330 natural gas buses and 370
diesel fuel buses. After receiving the new buses and retiring 50 older diesel
buses, approximately 75% of the Valley Metro fleet will be natural gas-
powered. All of the existing and newly ordered buses use liquefied natural gas
(LNG) for fuel. Since inception of the Phoenix long-term LNG supply contract,
the price has always been lower than diesel fuel, says Kelly.

    Production of the C8.3G Plus is scheduled to begin this month by Cummins
Inc. at its engine plant in Rocky Mount, North Carolina. This advanced version
of the C8.3G engine, which Cummins has produced since 1996, is designed for
school, shuttle and transit buses and for urban work trucks like refuse
haulers. The Cummins distributor responsible for the Phoenix bus engine order
is Cummins Southwest of Phoenix.
