Ram Will Be Building Cummins Diesel Pickups Until 2030 … At Least
The updated 2025 Ram Heavy Duty and Chassis Cab pickups will be rolling into showrooms soon with new Cummins diesel engines and they’re gonna keep on rolling for a few more years.
Ram and Cummins have officially extended their relationship through 2030, which syncs with the expected product cycle of the new trucks.
Ram has been using Cummins engines since 1989 when it introduced a 5.9-liter straight-six-cylinder with 160 hp and 400 lb-ft in its 3/4 and 1-ton trucks.
The newest 6.7-liter turbocharged inline-six-cylinder is available with up to 430 hp and 1,075 lb-ft in the Ram 2500 and 3500 pickups.

“We’ve improved the power, efficiency, serviceability and driveability of our latest 6.7L Turbo Diesel engine, making the 2025 Ram Heavy Duty lineup the most desirable yet,” Cummins Vice President Jane Beaman said in a news release.
A version rated at 360 hp and 800 lb-ft is also being offered in Chassis Cab models. A gasoline 6.4-liter Hemi V8 is also available in both the Heavy Duty and Chassis Cab trucks. According to Ram, more than 70% of its heavy truck buyers order a diesel engine.

Ram no longer offers a diesel or V8 engine in the light duty Ram 1500, but that could change. Returning brand CEO Tim Kuniskis recently said it was “anti-American” to take the option away from its customers and that it could potentially bring it back, although nothing has been confirmed.
Ford and GM offer V8s in their light duty trucks and the Chevy Silverado 1500 and GMC Sierra 1500 are available with a 3.0-liter turbocharged straight-six-cylinder diesel rated at 305 hp and 495 lb-ft.
