LOUISVILLE, Ky. (March 21, 2012) -

Cummins Inc. (NYSE: CMI) announced today its product solutions that will be available to North American trucking customers in 2013. Product improvements continue to offer customers better reliability and better fuel economy across a full lineup of diesel and natural gas commercial vehicle engines.

Cummins engines will deliver up to 2 percent fuel economy improvement over today’s products and will use the same proven high-pressure common rail fuel systems, VGT™ Turbocharger and fully integrated electronics for improved combustion efficiency, performance and reliability. Base engine improvements reduce the parasitic load on the engine through high-efficiency water, fuel and lube pump systems. Cummins engines will meet the 2014 fuel efficiency and greenhouse gas (GHG) standards beginning in January 2013.

“Customers can count on Cummins,” said Rich Freeland, Cummins Vice President and President – Engine Business. “We met the EPA 2010 standard on time, and our engines have earned their industry-leading reputation for great reliability and fuel economy. Our product development teams are delivering even better products where it counts – to our customers – and our engines are meeting the 2014 fuel-efficiency and GHG standards a full year early.”

Cummins will build on the success of its U.S. Environmental Protection Agency (EPA) 2010 MidRange and Heavy
Duty products with the same capable base engines and emissions architecture for 2013. All commercial vehicle diesel engines feature the Cummins Emission Solutions EcoFit™ Ultra-Low Emissions exhaust aftertreatment system, integrating a Diesel Particulate Filter (DPF) and Selective Catalytic Reduction (SCR). On-Board Diagnostics (OBD), proven on hundreds of thousands of engines since 2007, will be extended across the entire lineup.
