Ram Power Wagon Finally Gets Cummins Diesel with 1,075 lb-ft of Mountain-Moving Torque

Starting the New Year with a Bang

Ram is kicking off 2026 in a big way by giving the 2500 Power Wagon an engine option that it always deserved. For the 2027 model year, the heavy-duty pickup is now (finally) available with a 6.7-liter Cummins High Output turbodiesel. Before you ask, yes, it comes with a tidal wave of torque.

There’s 1,075 lb-ft of it, to be exact, making it the torquiest in its class as Ram claims. And if that’s still not enough, the big-block straight-six diesel also produces 430 hp. Granted, its weight means it won’t be scaring sport sedans off the line, but we’re pretty sure it can tow a couple of them without breaking a sweat.

A Long-Requested Model

According to Ram CEO Tim Kuniskis, the brand’s customers have long wanted to have the option of putting the 6.7-liter Cummins specifically under the hood of the Power Wagon. Prior to this announcement, it “only” came with the 6.4-liter HD Hemi V8, while the Laramie trim and up could be ordered with one.

“Matching the Power Wagon with the Cummins turbo diesel delivers everything our hardcore Ram fans expect: off-road capability with the best diesel in the HD segment. It’s the Power Wagon they’ve been waiting for,” said Kuniskis.

Towing and Hauling

Of course, we can’t talk about an HD pickup without mentioning its towing and hauling capacities. Ram claims it can pull nearly 20,000 lbs and has a payload capacity of about 3,000 lbs. There are also a couple of options available to make towing easier in the diesel-fed Power Wagon.

These options include a fifth-wheel/gooseneck preparation kit on the bed, along with packages such as the Towing Technology Group and Tow Technology Plus Group. Ticking those options adds conveniences such as additional cameras, tire pressure monitoring for trailers, a digital rearview mirror (for Tow Technology Plus), and more. Self-leveling automatic air suspension can also be specified, and includes a bed-lowering mode.

Other Highlights

This being the Power Wagon trim of the 2500, the Cummins-powered version also benefits from items such as the standard skid plates and rock sliders, along with Bilstein monotube dampers. There are locking differentials at the front, center, and rear, while 34-inch all-terrain tires provide traction on the rough stuff. It also has a disconnecting sway bar for increased suspension articulation — a huge plus when tackling deep moguls.

Standard features include advanced driver-assist features, a 12-inch Uconnect 5 touchscreen infotainment system, front and rear parking aids and cameras, and an integrated trailer brake controller. For options, the screen can be upgraded to 14.5 inches, an additional screen for the front passenger, a nine-speaker Alpine sound system, or a 17-speaker Harman/Kardon unit, and extended leather. And for those planning to venture even deeper off-road, one can specify the massive 50-gallon tank for an even longer range.

The 2027 Ram 2500 Power Wagon will hit showrooms by mid-2026 and carry a price tag of $88,470. For those who can’t wait that long, there are also new trims for the full-size pickup that have been added for 2026.
