The Cummins-Powered Ram Power Wagon Is Here

For years, hardcore truck fans have been asking the same question: Why doesn’t the Ram Power Wagon get the Cummins diesel? Now there’s an answer, and it’s loud, torquey, and unapologetically overbuilt.

Ram has officially unveiled the 2027 Ram Power Wagon with the 6.7-liter Cummins High-Output turbo diesel, and it’s exactly what enthusiasts have been waiting for. This is the most off-road-capable full-size pickup on the market, now paired with the most legendary diesel engine in the heavy-duty segment.

Cummins Power Meets Power Wagon Muscle

At the heart of the new Power Wagon is the 6.7-liter Cummins HO inline-six, producing 430 horsepower and a best-in-class 1,075 lb.-ft. of torque. That torque figure alone puts it at the top of the diesel HD class, but the real story is how Ram has integrated that power into a truck built to leave pavement behind.

This marks the first time a Cummins diesel has ever been offered in a Power Wagon, expanding Ram’s halo truck lineup and answering one of the longest-running fan requests in the brand’s history.

Paired with the TorqueFlite HD eight-speed automatic transmission and a new 3.42 rear axle ratio, the setup delivers confident towing and strong low-end grunt, while also improving highway efficiency and reducing noise and vibration at speed.

Still the King of Off-Road Full-Size Trucks

Despite adding diesel muscle and serious towing capability, the Power Wagon hasn’t softened its off-road edge—far from it.

The 2027 Power Wagon with Cummins retains its title as the most off-road-capable full-size pickup, thanks to a long list of purpose-built hardware:

• Front and rear electronic-locking differentials
• Class-exclusive disconnecting front stabilizer bar
• Bilstein monotube shocks
• Solid front and rear axles
• Extensive underbody skid plates
• Mopar rock rails for trail protection

Out back, Ram’s class-exclusive five-link coil rear suspension replaces traditional leaf springs, improving ride quality and articulation while maintaining serious payload capability. For the first time ever, buyers can also option automatic-leveling rear air suspension, which keeps the truck level under load and even includes a bed-lowering mode for easier trailer hookup.

Built to Go Far—Literally

Overlanders and long-haul adventurers will appreciate the Power Wagon’s new endurance-focused upgrades. A 31-gallon fuel tank, combined with diesel efficiency, delivers an estimated 600 miles of driving range, making it ideal for remote travel where fuel stops are few and far between.

With 13.2 inches of ground clearance, a 26.1-degree approach angle, and 34-inch all-terrain tires, the Power Wagon is ready for rocky trails, deep ruts, and everything in between—straight from the factory.

Serious Towing and Work Capability

The Cummins-powered Power Wagon isn’t just about trails—it’s also a legit workhorse.

• Nearly 20,000 pounds of towing capability
• Almost 3,000 pounds of payload
• First-time availability of fifth-wheel and gooseneck prep
• Advanced towing tech like trailer reverse steering control, 360-degree cameras, and trailer tire pressure monitoring

Whether you’re hauling toys, equipment, or a camper into the backcountry, this Power Wagon is built to handle it.

Bold Looks, Premium Interior

Visually, the Power Wagon leans into its rugged identity with:

• Iconic “Power Wagon” bedside decals
• A standard sport performance hood
• Satin Black Cummins badging
• Functional wheel arch extensions and trail-ready body protection

Inside, Ram delivers what may be the most premium interior in the heavy-duty segment. Buyers can choose everything from a heated cloth bench seat to heated and ventilated leather-trimmed buckets, with available features like:

• Up to a 14.5-inch Uconnect 5 touchscreen
• Class-exclusive front passenger interactive display
• Alpine or Harman Kardon premium audio
• Advanced safety tech including adaptive cruise control and blind-spot monitoring with trailer coverage

A Legendary Nameplate, Reinvented Again

The Power Wagon name dates all the way back to 1945, when it evolved from military-duty Dodge trucks into a civilian four-wheel-drive icon. Reintroduced in 2005, the Power Wagon has always represented the extreme end of factory off-road capability—and the 2027 model takes that legacy further than ever before.

Pricing and Availability

The 2027 Ram Power Wagon with Cummins turbo diesel arrives in the second half of 2026, with a starting price of $88,470, including destination. For fans who’ve been asking for a diesel Power Wagon for years, this isn’t just another trim level—it’s the truck they’ve been waiting for.
