2027 Ram Power Wagon Overview: The Cummins Diesel Arrives
The 2027 Ram Power Wagon finally offers a Cummins diesel, and it marks the first diesel option in the model’s modern history. However, Ram pairs the win with a hard trade-off: the signature front winch goes away on diesel trucks. For off-road buyers, the Power Wagon now poses a real choice between torque and recovery gear. This explainer breaks down what the Cummins adds, what Ram cut, the price, and how the two engines compare.
Ram revealed the diesel Power Wagon in early 2026, and TFLtruck published a first drive in mid-2026. The truck rides on the Ram 2500 heavy-duty platform. Still, the Power Wagon has always stood apart as the most trail-ready factory HD pickup. Now the Cummins reshapes what the truck does best.

What the Diesel Adds
The headline number is torque. The Cummins 6.7-liter inline-six produces 430 horsepower and 1,075 lb-ft. For comparison, the carryover 6.4-liter Hemi V8 makes 405 horsepower and 429 lb-ft. Therefore the diesel more than doubles the gas engine’s twist.
The extra torque changes the truck’s job. Ram now rates towing at nearly 20,000 pounds with the available fifth-wheel gooseneck hitch. Because diesel torque builds low in the rev range, it also helps at crawling speeds on the trail. Our guide to the benefits of diesel torque off-road explains why.
Buyers also gain range and efficiency. Diesel HD trucks typically travel farther per tank and hold better fuel economy under load. As a result, long tows and remote trips ask for fewer fuel stops.
The Trade-Off: Ram Deletes the Winch
To fit the Cummins, Ram removed the front winch on diesel Power Wagons. The diesel needs the nose space for charge-air cooling, and the heavy engine adds weight over the front axle. As a result, the winch lost its spot.
Ram CEO Tim Kuniskis explained the call directly. “Okay, fine. Screw it. Get rid of the winch. We’ll figure it out later,” Kuniskis said. He added the rest of the truck’s capability stays intact. Still, for overlanders who rely on a factory winch for self-recovery, the deletion stings.
For now, diesel buyers add an aftermarket winch or choose the Hemi to keep the factory unit. Meanwhile, Ram hinted a future update might restore the winch on diesel trucks. Until then, the Hemi remains the only Power Wagon with a factory recovery tool up front.
Off-Road Hardware the Diesel Keeps
Beyond the winch, the Power Wagon keeps its hardcore kit. The diesel retains electronically locking front and rear differentials, a disconnecting front sway bar for articulation, and 33-inch all-terrain tires. Ground clearance measures about 12.6 inches, slightly less than the gas truck, while steel skid plates guard the underbody.
Standard four-wheel drive pairs with an eight-speed automatic and a 3.42 rear axle. Ram also adds an available self-leveling rear suspension for heavy loads. For context, our ranking of the most capable factory off-road truck placed the Power Wagon near the top for years.
Price and Availability
The diesel Ram Power Wagon starts at $88,470. The Cummins therefore adds a premium over the Hemi version; across Ram’s 2500 lineup, the diesel upgrade runs around $12,500. Ram plans to reach dealerships in the second half of 2026. The gas truck stays the cheaper entry point for buyers who want the factory winch.
Diesel vs Hemi: Which Ram Power Wagon Fits You?
The choice comes down to how you use the truck. Heavy towers and high-mileage drivers gain the most from the Cummins, with its torque, towing, and range. On the other hand, trail-focused buyers who value the factory winch might lean Hemi.
Price also factors in. The diesel commands a premium up front, and diesel fuel, DEF, and service add ongoing costs, even though it sips less under load. To weigh it fully, compare diesel versus gas trucks for overlanding.
The split is concrete. For heavy, frequent towing or high highway mileage, the Cummins earns its premium. Conversely, for technical trail work and factory self-recovery, the Hemi keeps the winch and costs less up front.
What It Means for Off-Road Buyers
So what does the diesel Power Wagon mean for off-road drivers? First, Ram closes a long-standing gap against Ford and GM diesels in this niche. Ram’s 1,075 lb-ft tops GM’s Duramax at 975, though Ford’s Power Stroke still leads at 1,200. Second, the winch deletion forces a real decision for recovery-minded buyers.
For now, the Cummins Power Wagon reads as a towing-first evolution of a trail icon. As demand data comes in, Ram might restore the winch and close the gap. Until then, buyers weigh torque against recovery gear. Our Ram off-road tips still apply to the new truck.
