Columbus, Ind. (January 12, 2009) -

Cummins Inc. (NYSE:CMI) reaffirmed today that its entire on-highway product range, including its industry-leading ISX, will be ready to meet the new Environmental Protection Agency (EPA) regulations for the North American market beginning in 2010. The breadth of Cummins 2010 product offerings demonstrates Cummins commitment to its customers as well as to the environment.

Customers’ concerns for economic solutions and satisfying environmental regulation will be the hallmark of Cummins product line. Cummins will offer a range of engines from the 6.7 liter ISB to 15 liter ISX, delivering best-in-class fuel economy and performance while complying with the EPA’s newest and most stringent emissions standards. This is a formula which customers need in today’s economy and environment, and is why Cummins advocates and supports the implementation of the EPA’s commitment to the lowest diesel emission levels in the world in 2010.

For 2010, Cummins will introduce the ISX15 which will provide substantial fuel economy improvement, stronger performance, faster throttle response and overall best-in-class drivability and reliability compared to today’s industry-leading ISX engine. The ISX15 will feature the new Cummins XPI fuel system, next-generation cooled EGR system, advanced VGT™ turbocharger and a new Cummins Aftertreatment System that incorporates Selective Catalytic Reduction (SCR) catalyst technology.

Cummins will also introduce the new ISX11.9, providing a compact and lightweight medium-bore engine ideal for vocational trucks, emergency vehicles and motorcoach applications. Building on Cummins Engine and Components Business expertise, the ISX11.9 will have common subsystems with the ISX15, including the XPI fuel system, VGT™ turbocharger, Cummins Aftertreatment System and advanced electronic controls.

The ISX engine is the market leader today in the North America heavy duty on-highway truck market. Cummins market share of the heavy duty on-highway business has grown from 27 percent in 2006 to over 45 percent in 2008.

Cummins will also offer its ISB6.7, ISC8.3 and ISL9 engines for 2010. Cummins MidRange engines deliver best-in-class fuel economy and reliability with high power-to-weight ratios, and have made significant market share gains in medium-duty truck and bus applications. The 2010 engines will all utilize Cummins VGT™ turbocharger, Cummins Aftertreatment System, a common ECM and advanced electronic controls. The ISC8.3 and ISL9 also feature Cummins XPI fuel system.

“Cummins 2010 engines will deliver what customers need in these challenging economic times,” said Jim Kelly – President, Engine Business. “The engines are already being built off our production lines for customer field tests. We’re getting great feedback from our field tests, and our products, our people and our customer support are ready for 2010. In addition to the fuel economy gains associated with SCR and our XPI fuel system, the performance and reliability enhancements that come with decreased EGR rates are even greater than we estimated, and we’re convinced now more than ever that SCR technology is the right technology for 2010.”
