Dongfeng Cummins Celebrates Its One Millionth Engine; Prototype of New 13-Liter Engine Showcased.

XIANGFAN, Hubei, China -- Dongfeng Cummins Engine Company Limited (DCEC), a 50-50 joint venture between Cummins Inc. and China's leading auto maker, Dongfeng Motor Corporation (DFM), has reached a significant milestone by producing its one millionth engine.

The engine, a Cummins ISLe to be installed in a Dongfeng heavy-duty Tianlong truck, highlights the companies' engine partnership in China that dates back to 1986.

"Today's celebration is not only a significant milestone for DCEC but also a pivotal moment for both Cummins and DFM," said Steve Chapman, Group Vice President - Emerging Markets and Businesses. "We could not have reached this achievement without the vision and hard work of many people at DFM and Cummins who together have created one of the most successful partnerships in the industry."

The companies also celebrated the completion of the prototype model of a new 13-liter engine being developed as part of a joint effort launched last year, and showcased DCEC's full line of Euro III-compliant engines, ranging in size from 4.5 liters to 8.9 liters.

The fully electronic 13-liter engine, which is expected to be ready for production in 2009, will feature a power range from 400 to 545 horsepower and is designed to be used in heavy-duty trucks above 40 tons gross weight. The engine will take advantage of Cummins' industry-leading technology that will make it capable of meeting future emission standards in global heavy duty markets.

"Working with Cummins offers us invaluable access to best-in-class engines and components," said Xu Ping, General Manager of DFM. "Cummins has been vital in building our position in the China market as a leading truck maker, as well as in our efforts to penetrate into the international markets."

DFM first licensed Cummins engine technology in 1986 and the two companies created the DCEC joint venture in 1996. In addition to the engine joint ventures, Cummins and DFM also are partners in a filtration operation in Shanghai and an exhaust product joint venture in Xiangfan, as well as in a technical center in Wuhan.

Cummins is the largest foreign investor in the China diesel engine industry, and its ties in the country date back over 30 years to 1975 when then-CEO J. Irwin Miller led the first Cummins delegation to China as part of a deal to sell 14 KV12 engines to a mining customer. Today, Cummins operates more than 20 facilities in China - including 13 manufacturing sites - with all areas of the Company's business represented in China.
