2027 Ram Power Wagon Gets First-Ever Cummins Diesel Option

The car world has taught us that sometimes it takes patience—not just money—to get what you want. Dodge released a modern version of the Power Wagon for the 2005 model year, but truck enthusiasts have been waiting since then for a diesel engine option. Well, the wait is finally over, as the 2027 Ram Power Wagon can now be ordered with the Cummins 6.7-liter turbo-diesel inline-six.

Way back in 2016, I had a chance to drive the redesigned 2017 Ram 2500 Power Wagon at the Texas Auto Writers Association’s Texas Truck Rodeo. This was an event where journalists drive a variety of trucks and SUVs to determine winners in various categories, including the Truck of Texas. While there, I asked a Ram representative why the Power Wagon wasn’t available with a Cummins diesel. He told me that it was due to packaging and dynamics: the position of the front winch would interfere with the placement of the charge air cooler, and the heavy Cummins would put too much weight over the front axle, detracting from the Power Wagon’s off-road abilities.

It seems Ram has worked out those engineering issues because a Cummins 6.7-liter turbo-diesel I6 is now on the options list. With 430 horsepower and 1,075 lb-ft of torque, it enables the Power Wagon to haul close to 3,000 pounds of payload and tow almost 20,000 pounds. A 31-gallon fuel tank provides up to 600 miles of range.

The optional Towing Technology Group makes pulling heavy loads more convenient with features such as trailer reverse guidance, a 360-degree camera system, and a trailer tire pressure monitoring system. Ticking the box for the Tow Technology Plus Group adds a digital rearview mirror and trailer reverse steering control.

There’s more to the Power Wagon than just the engine, though. As usual, it has front and rear electronic lockers, an electronically disconnecting sway bar for better articulation, and five-link coil rear suspension. Two more firsts for the juggernaut are the available fifth-wheel/gooseneck setup and an automatically leveling rear air suspension. To better harness the Cummins’ enormous power, Ram changed the rear end to run the 3.42 gears introduced on the 2025 Ram Heavy Duty lineup, and installed larger 38-millimeter rear axle shafts.

In its base form, the Power Wagon comes equipped with a heated cloth bench seat up front, Uconnect 5 with a 12-inch touchscreen, integrated trailer brake controller, ParkSense front and rear park assist, and more. Available upgrades include heated and ventilated leather bucket seats, 14.5-inch Uconnect 5 touchscreen, interactive display for the front passenger, towing and off-road information pages, and a nine-speaker Alpine or 17-speaker Harman Kardon audio system. Opting for the Level 2 Equipment Group upgrades the cabin with more leather touchpoints, including the grab handles and column shifter for the TorqueFlite HD eight-speed automatic.

Prices for the Cummins-powered 2027 Ram Power Wagon start at $88,470 (including destination). You’ll start seeing it in dealer showrooms in the second half of this year . . . and on a trail near you soon after that.
