2027 Ram Power Wagon is a diesel-powered off-roader with more than 1,000 pound-feet of torque – Jalopnik

If you’re into trucks, the Ram Power Wagon is undoubtedly one of the sickest full-size options on sale right now, with its chunky looks and off-road focus setup. Yet something was always missing: a Cummins turbodiesel engine. That is, until now. Tim Kuniskis, the madman at the helm of Ram, says the upcoming 2027 Power Wagon will have a turbocharged 6.7-liter Cummins diesel engine, and the specs make it sound like it will produce enough power to resurrect the Dodge brothers.

Admittedly, the horsepower isn’t much to write home about. The big inline-six only makes 430 horsepower, but torque is what this thing is all about, baby – 1,075 pound-feet to be exact. That power is provided by a strengthened eight-speed automatic transmission and a larger axle ratio of 3.41:1. It’s enough to give the Power Wagon a payload of “almost” 3,000 pounds and a towing capacity of 20,000 pounds. Not too shabby.

The big powerhouse also comes with larger rear axles (now 34mm) to handle the higher torque, and available auto-leveling rear air suspension, which can help prepare for the newly available fifth wheel gooseneck trailer. Diesel Power Wagons will be equipped with 20-inch wheels and 34-inch tires. Gasoline cars get 17s. It keeps the coil-spring front and rear axles alive, each of which is fitted with electric differential locks, with the rear acting as a limited-slip differential. It also has Bilstein shocks and loads of underbody protection.

The Cummins Power Wagon is no different from the gas truck as it is only offered in a 4×4 crew cab configuration with a 6-foot bed. It even has the same sporty hood and standard rock rails along the sides that complement the Power Wagon graphics we’re so familiar with. Of course, there are now a few Cummins badges included as well. It also has functional wheel arch extensions to make room for the much larger tires. Buyers can add things like body-color door handles, expanded LED lighting for the cab and bed, and the RamBox cargo management system. They can also throw in mirrors for trailers.

On the inside, there are some very old-fashioned cloth bench seats that are heated front and rear as standard, as well as a not-so-old-fashioned 12-inch infotainment display. If that’s not your style, opt for the heated and ventilated leather front bucket seats, 14.5-inch center display and upgraded sound systems. There are also a number of available driving aids to make piloting a beast like this a little more manageable. The Power Wagon’s interior is quintessential Ram, which is to say it’s just about the best truck interior you’ll find on the market.

Buyers will have to pay for the privilege of the Cummins Wagon. It starts at $88,470, including destination. That’s almost $13,000 more than the V8 Power Wagon, but it roughly matches the premium the Cummins commands over other Ram 2500 V8 offerings. It is expected to hit dealerships sometime in the second half of 2026.

It makes sense to mount the Cummins on the Power Wagon, right? It’s a big truck that deserves a big engine, but be warned: there will be some tradeoffs and sacrifices if you go with the Cummins over the 6.4 Hemi. The inline-six diesel engine is longer and heavier than the V8, meaning the Power Wagon’s iconic factory winch-prepped bumper won’t fit, according to MotorTrend. The engine’s plumbing will also cause packaging issues with the truck’s sway bar disconnect systems and limited slip differentials, so there will be some compromises in off-road readiness, not to mention the fact that it weighs so much. Weight is kind of the enemy of rock crawling – something the gas-powered Power Wagon is quite good at. Yet even the diesel truck has an approach angle of 26.1 degrees and a departure angle of 26 degrees, a ground clearance of 13.2 inches and a breakover angle of 20.6 degrees.

None of that has deterred Aries, however. Kuniskis said customers have been telling them “for years” to put the diesel in the Power Wagon, and who are they to deny the customer a compromised product? In short, customers can decide whether they want a bona fide rock crawler in the gas-powered Power Wagon or a towing monster with a very sick appearance in the diesel-powered Power Wagon.
