COLUMBUS, IN - Cummins Inc., announced a multiyear extension of its current agreement with Chrysler Group LLC. Cummins will supply 6.7L Turbo Diesel engines for Ram Heavy Duty pickups and Chassis Cab trucks while continuing to grow its partnership with Chrysler, which began 21 years ago.

Cummins has produced over 1.7 million Cummins Turbo Diesel engines for Dodge Ram Heavy Duty trucks since 1989. Today, over 80 percent of Ram Heavy Duty truck customers purchase their truck with the legendary Cummins Turbo Diesel.

The first Cummins Turbo Diesel was used in the 1989 Dodge Ram, with projected sales of less than 5,000 engines. Actual sales exceeded 20,000 engines in the first year, signaling to the market that a powerful new combination had been created.

The first Cummins Turbo Diesel was a 5.9L at 160 hp (119 kW) and 400 ft.-lb. (542 N•m) of torque. Today's 6.7L Turbo Diesel delivers 350 hp (261 kW) and 650 ft.-lb. (881 N•m) of torque. This 118-percent increase in horsepower and 86-percent increase in torque have been achieved while also reducing exhaust emissions by 90 percent. In 2007, Dodge and Cummins produced the cleanest heavy-duty diesel pickup in the market by meeting U.S Environmental Protection Agency (EPA) 2010 emissions levels a full three years in advance.

"Cummins and Chrysler have a long and important history together," said Dave Crompton, VP and General Manager, MidRange Engine Business. "The Chrysler business continues to be a key part of our MidRange engine business. Cummins is proud to supply engines for the award-winning Ram Heavy Duty and to continue working with Chrysler to develop best-in-class products that customers can trust and depend on now and in the future."
