Cummins Inc. Named "Newsmaker Of The Year" by Diesel Progress.

COLUMBUS, Ind. -- Cummins Inc. (NYSE:CMI) announced today that it has been named the 2007 Newsmaker of the Year by Diesel Progress magazine, honoring the company's continued commitment to communicating advancements in diesel engine and emissions technology. The award is featured in the December issue of Diesel Progress.

The Diesel Progress Newsmaker of the Year award, now in its eleventh year, honors the company, person, product, technology, market or industry topic that made the most news during the year. This is the second time Cummins has received the award.

The 2007 award highlights three significant Cummins technology announcements: the launch of the 2007 Dodge Turbo Diesel, the first engine to meet the 2010 heavy-duty diesel regulations; the company's Heavy-Duty and MidRange solutions for the North American EPA 2010 emission standards, and the solution to meet the Tier 4 Interim/Stage IIIB regulations which will take effect in 2011.

Mike Osenga, publisher of Diesel Progress, noted Cummins announcements, stating that the company's "overall performance in a tough truck year may, once and for all, have redefined Cummins as something other than just a truck engine supplier." He continued, "In the end, everything Cummins did this year, from the early launch of the Dodge Ram Turbo Diesel and its innovative NOx adsorber to the announcement of a non-SCR solution for 2010 heavy-duty trucks to the recent unveiling of the Tier 4 off-highway strategy, dominated the industry news in 2007."

"The Diesel Progress award is a terrific recognition for Cummins and provides a great example of how we are succeeding in our efforts to be the first choice of our customers - whether it be in the pickup truck market with the Dodge Ram, our industry-leading position in the North American on-highway markets or our Tier 2 and Tier 3 off-highway products that were delivered on-time and are performing as planned," said Joe Loughrey, Cummins President and Chief Operating Officer.
