2027 Ram 2500 Power Wagon with Cummins diesel StellantisFor the first time, the 2027 Ram 2500 Power Wagon will offer the long-entrenched 6.7‑liter Cummins High-Output (HO) turbodiesel inline six-cylinder engine, generating 430 horsepower and a stump-pulling 1,075 pound-feet of torque. And while the 2027 Ram 2500 Power Wagon comes exclusively as a 4x4 crew cab with a 6-foot-4 bed, there are other Ram HD pickups that offer an 8-foot bed, as well as a Mega Cab (with the smaller bed). It's available on select trims, including Tradesman, Big Horn/Lone Star, Laramie, Limited, and Limited Longhorn, but not Power Wagon. Ram's latest addition of the Cummins diesel for the 2500 Power Wagon brings grunt-force capability to the off-road segment for 2027.
