Cummins Westport receives orders for 108 natural gas bus engines

    VANCOUVER, Sept. 6 - Cummins Westport Inc., a joint venture
company owned by Cummins Inc. of Columbus, Indiana and Westport
Innovations Inc. of Vancouver, British Columbia announced today that
it has received two orders for a total of 108 low-emissions natural gas bus
engines for Southern California.

    The orders, for Cummins Westport C8.3G Plus engines, involve the transit
agencies for San Diego and San Bernardino. The engines will be installed in
new transit buses manufactured by New Flyer of America of Crookston,
Minnesota. Delivery of the buses to the transit agencies is scheduled to be
completed by December 2001. The Cummins distributor responsible for both
orders is Cummins Cal Pacific of Los Angeles.

    "These two orders represent the first significant sales of our newly
developed C8.3G Plus engine for buses in Southern California," said Guff
Muench, President and Chief Executive Officer for Cummins Westport Inc. "We
expect strong continuing demand in this area because of our competitive
performance advantages and because of Southern California's stringent air
quality regulations."

    San Diego Metropolitan Transit Development Board ordered 71 of the
natural gas buses for San Diego Transit Corp. (SDTC) and 26 of the natural gas
buses for transit agencies in adjacent communities. When the new buses are in
service and older diesels are retired, approximately 60% of SDTC's fleet of
350 buses will be natural gas powered.

    The San Bernardino County transit operator, Omnitrans, ordered 11 new
natural gas buses. After completion of the delivery and retirement of older
diesel buses, Omnitrans' natural gas buses will represent approximately 64% of
the total fleet of 176 buses.

    Production of the C8.3G Plus began in June by Cummins Inc. as an advanced
replacement for the C8.3G engine, which Cummins has produced since 1996. The
C8.3G Plus was certified as a low-emissions engine by California regulators in
July. It is designed for buses and trucks and can operate with either
compressed natural gas (CNG) or liquefied natural gas (LNG). The San Diego and
San Bernardino orders will use CNG.
