Owners of the Ram 2500 and 3500 now have a diesel engine option from Cummins that offers two variants: a standard output of 370 hp with 850 Ib ft of torque, and a high output of 400 hp with a remarkable 1,000 Ib ft of torque. Cummins also showcased the latest turbocharging, filtration and light-duty after-treatment technology.

“The Cummins name has been synonymous with technological innovation and reliability since 1919,” said Melina Kennedy, General Manager–Cummins Pickup segment. “We’re proud to introduce our most powerful 6.7L engine ever on the year of our centennial–setting the new standard in the heavy-duty pickup market.”

The 6.7L engine has increased peak cylinder pressure capability, high-temperature exhaust valves activated by all-new hydraulic lash adjusters, and a high strength alloy 10-bolt crankshaft. A larger Cummins-Holset variable-geometry turbocharger pumps 33 pounds per square inch (psi) of fresh air into the engine. The engines new fuel-delivery system involves a 29,000 psi (2,000 bar) fuel pump and fuel rail with Cummins Filtration “filter in filter” NanoNet® technology.

“Together, RAM and Cummins have accomplished many milestones and technological advances. From the time the first prototype truck was put together in the 1980s to now, breaking the 1,000 Ib ft barriers together, exemplifies the strength of our partnership,” stated Srikanth Padmanabhan, Vice President, Cummins Engine Business.
