Louisville, Ky. (March 24, 2010) -

Cummins Inc. (NYSE: CMI) announced that its new on-highway engines for 2010 are in full production and meeting customers’ expectations of delivering better fuel economy and performance. The Cummins engine lineup for on-highway applications is on display at the Mid-America Trucking Show in Louisville, Ky., from March 25-27.

Cummins began producing the near-zero-emissions EPA 2010 engines in 2009 and continued with full production in January of this year. To date, Cummins has produced over 2,500 EPA-certified 2010 engines at Cummins manufacturing facilities in Jamestown, N.Y., and Rocky Mount, N.C.

Leading to the full production of the 2010 engines, Cummins followed stringent product-testing protocol through which engines are rigorously tested for performance and reliability. Cummins utilizes cutting-edge technology for in-house testing through the use of automated data analysis. Cummins has equipped more than 200 vehicles, including internal test vehicles and customer field test vehicles, with a proprietary datalogger that enables Cummins to log nearly 240 different variables while the vehicle is in operation. This method of acquiring, processing and analyzing the constant feed of data allows Cummins engineering to immediately identify and address any potential issues prior to production introduction.

Additionally, Cummins has accumulated more than eight million miles of real-world experience by having the products operated by over 80 customers in normal daily operations.

Cummins EPA 2010 engines have been tested, validated and are available in nearly 180 installations for on-highway vehicles. This vast range of on-highway applications includes heavy- and medium-duty trucks, school buses, shuttle buses, transit buses, recreational vehicles, motorhomes, motorcoaches, and fire-and-emergency vehicles.

“The same rigorous testing and product validation are done regardless of the application in which the engine will be installed,” said Sean Milloy, Chief Technical Officer – Cummins Engine Business. “In fact, due to the nature of some duty cycles, more aggressive testing is done with some applications.  The engineering excellence of Cummins team allows us to leverage the knowledge gained from every test mile and hour performed in all of these installations.”

The 180 vehicle installation applications available with Cummins 2010 power are a result of extensive collaboration with over 60 vehicle manufacturers. “The work that our teams have accomplished demonstrates the commitment that Cummins has to our OEM partners,” said Rich Freeland, President – Cummins Engine Business. “The range of vehicle applications with Cummins 2010 engines reaffirms our ability to deliver the best products and support to our customers.”

Cummins 2010 products will provide improved fuel economy, performance and reliability as compared with its previous industry-leading products. “The data that we are collecting from our internal product testing, coupled with the feedback from our customers, is validating that our 2010 engines are delivering on our promises, and there are cases where the results are even better,” said Jeff Jones, Vice President – Sales and Market Communications.

The Cummins suite of engine offerings for 2010 will incorporate an enhanced cooled Exhaust Gas Recirculation (EGR) system, a single VGT™ Turbocharger and the Cummins Aftertreatment System with Selective Catalytic Reduction (SCR) technology, providing near-zero emissions to meet EPA 2010 regulations.

The Cummins ISX15 is fully EPA- and ARB-certified and is ideal for Class 8 on-highway trucks that require the performance of a big-bore engine.  The ISX15 features the new Cummins Xtra-High Pressure Injection (XPI) fuel system, which is able to produce extremely high pressure independent of engine speed. The Cummins proprietary fuel system enables controlled fuel injection events and is instrumental in achieving up to five percent better fuel economy than the previous model.

Cummins MidRange engine lineup for on-highway applications includes the ISB6.7, ISC8.3 and the ISL9, all of which are ideally suited for medium-duty truck, shuttle bus, school bus, and fire-and-emergency vehicle applications.

Cummins ISX11.9 rounds out the product portfolio for on-highway applications and will be in full production in August.
