Cummins Announces High Output 6.7L Turbo Diesel



COLUMBUS, Ind. (Feb. 10, 2011) - Cummins Inc. today announced the release of its High Output 6.7L Turbo Diesel for Ram Heavy Duty pickup trucks. This new high-output rating produces more torque where customers need it most, up to a peak of 800 lb-ft (1,085 N•m).

With 800 lb-ft of torque at 1600 rpm, power is increased across a wide speed range of 1200-2700 rpm. This delivers up to 46 additional hp at typical highway cruising speeds while maintaining 350 horsepower at 3000 rpm.

"The 6.7-liter Turbo Diesel's base engine is the Cummins ISB, which is used in a variety of demanding applications and can produce significantly higher ratings than what is offered in pickup trucks," said Scott Henry, Chief Engineer for the Cummins Turbo Diesel. "From an engineering perspective, our work to develop the high-output rating for the 6.7-liter Turbo Diesel was in the advanced-performance tuning. The crankshaft dampener was the only engine part that we needed to change as a result of the increased torque."

Cummins will begin producing its High Output 6.7L Turbo Diesel engines at its Columbus MidRange Engine Plant (CMEP) in the second quarter of this year. They will be available in Ram Heavy Duty pickup trucks with the automatic transmission option.

Along with the new 800 lb-ft torque rating, the Cummins 6.7L Turbo Diesel continues to offer the most powerful integrated exhaust brake available in a heavy-duty truck. Cummins best-in-class integrated exhaust brake, with a full 222 braking horsepower at the wheel, gives Ram Heavy Duty pickup customers more confidence while towing the heaviest loads down the most severe grades.

"Eight hundred foot-pounds of torque is enormous force, and with the Cummins inline six-cylinder configuration, customers really get the best of both worlds," Henry stated. "They get high-output torque, along with the durability and low cost of ownership expected from an inline six. And this is still the only diesel in a heavy-duty pickup that doesn't need Diesel Exhaust Fluid. The Cummins Turbo Diesel has produced decades of legendary performance in Ram Heavy Duty trucks, and will continue to be the best-in-class engine that customers can depend on for years to come."
