Cummins Inc. has signed a multiyear extension of its current agreement to supply Chrysler Group LLC with 6.7-liter turbodiesel engines for the automaker’s Ram Heavy Duty pickups and Chassis Cab trucks.
The announcement is a vote of confidence in Chrysler from a key supplier and both companies said the partners expected to expand on the 21-year-old relationship in the future.
Cummins has produced over 1.7 million Cummins turbodiesel engines for Dodge Ram Heavy Duty trucks since 1989. More than 80% of Ram Heavy Duty truck customers purchase their truck with the Cummins “oil-burner,” which not only gives them significantly power mileage than conventional gasoline powertrains but also a lot more cargo-hauling torque.
The first Cummins Turbo Diesel, in 1989, was a 5.9-liter V8 rated at 160 hp and 400 lb-ft of torque. Today the 6.7-liter Turbo Diesel delivers 350 hp and 650 lb-ft.
