The Power Wagon Gets the Cummins: Ram's Off-Road Icon Levels Up for 2027

Ram truck enthusiasts have been asking for years, and the automaker has finally delivered. The 2027 Ram Power Wagon now offers the legendary 6.7-litre Cummins High-Output turbo diesel engine - marking the first time this powerhouse has been available in Ram's most off-road-capable full-size pickup. With 430 horsepower and 1,075 lb-ft of torque, the Power Wagon with Cummins turbo diesel brings unprecedented capability to drivers who demand both extreme off-road performance and serious towing muscle.

This addition marks a major milestone in the Power Wagon's storied history, which dates back to 1945. The diesel option expands the truck's appeal to overlanders, commercial users, and recreational haulers who need extended range, confident towing, and the proven durability of Cummins diesel technology - all without sacrificing the Power Wagon's legendary trail credentials.

Cummins Power and Off-Road Capability

The 6.7-litre Cummins High-Output turbo diesel inline-six engine is the same proven powerplant found across Ram's Heavy Duty lineup. This turbocharged, intercooled diesel produces 430 horsepower and delivers 1,075 lb-ft of torque, providing strong pulling power whether you're hauling a loaded trailer or crawling over rocky terrain. The engine features electronic high-pressure common rail fuel injection and selective catalytic reduction (SCR) emission controls, ensuring modern efficiency and compliance.

Paired with the TorqueFlite HD eight-speed automatic transmission, the 2027 Power Wagon with Cummins turbo diesel adopts a 3.42 rear axle ratio. This setup delivers higher final drive ratios in gears one through six for confident towing performance and acceleration, and lower ratios in gears seven and eight for improved highway fuel economy and reduced noise, vibration and harshness (NVH). The transmission's adaptive electronic control and Electronic Range Select (ERS) manual control give drivers precise command over power delivery in any situation.

Cummins Diesel Highlights:

• 6.7-litre inline-six turbocharged diesel engine
• 430 horsepower and 1,075 lb-ft of torque
• TorqueFlite HD eight-speed automatic transmission
• 3.42 rear axle ratio optimized for towing and fuel efficiency

Extended Range for Remote Adventures

One of the diesel option's key advantages is extended range. The 2027 Ram Power Wagon with Cummins turbo diesel comes standard with a 117-litre fuel tank, which pairs with diesel efficiency to deliver an estimated 966 kilometres of range. This capability is ideal for overlanders and remote workers who spend days off the beaten path, where fuel stops are scarce and reliability is paramount.

The diesel's superior fuel economy compared to gasoline engines means fewer interruptions during long hauls or multi-day off-road expeditions. Whether you're towing a camper to a remote campsite or hauling equipment to a job site far from civilization, the Cummins diesel ensures you can go farther with confidence.

Uncompromised Off-Road Performance

Despite the addition of diesel power, the 2027 Ram Power Wagon retains its title as the most off-road-capable full-size pickup. The truck features front and rear electronic-locking differentials activated by electromagnetic actuators (E-lockers), ensuring maximum traction in challenging terrain. When disengaged, the rear locker functions as a mechanical anti-slip differential, enhancing passive grip on loose surfaces.

The Power Wagon's axles are built by American Axle Manufacturing, measuring 235 millimetres (9.25 inches) in the front and 292 millimetres (11.5 inches) in the rear. Robust rear axle shafts are upgraded to 38 mm, delivering rotating force directly to the 34-inch tire and wheel combination. The truck rides on 20-inch Satin Black wheels with machined accents, wrapped in 34-inch all-terrain tires designed for both on-road comfort and off-road durability.

Ram's five-link coil rear suspension remains a cornerstone of the Power Wagon's capability. This superior design offers improved ride quality and articulation compared to traditional leaf springs, balancing payload capability with ride comfort. Bilstein monotube shocks cushion both the front and rear suspension, while a Bilstein dampener connecting the rear axle to the frame provides even more control and stability. For the first time, the Power Wagon diesel can also be optioned with Automatic-Leveling Rear Air-Suspension, which maintains a level stance under heavy loads and incorporates a Bed Lowering Mode for effortless trailer hook-up.

The front suspension features a unique-to-model design with Bilstein monotube shocks and an electronic disconnecting sway bar. This allows the front axle to move more independently of the truck's frame, improving articulation and overall off-road capability. Underbody protection includes skid plates for the Diesel Exhaust Fluid (DEF) tank, fuel tank, and transfer case, while standard Mopar accessory rock rails protect the cab and chassis during trail runs.

Off-Road Features:

• Front and rear electronic-locking differentials (E-lockers)
• Five-link coil rear suspension with Bilstein shocks
• Electronic disconnecting front stabilizer bar
• 320 millimetres (12.6 inches) of ground clearance
• 24.6-degree approach angle and 25.5-degree departure angle
• 19.7-degree breakover angle
• Standard Mopar accessory rock rails and extensive underbody protection

Towing and Payload Powerhouse

The 2027 Ram Power Wagon with Cummins turbo diesel is engineered to handle serious work. With a tow rating of nearly 9,072 kilograms (20,000 pounds) and a payload capacity of almost 1,360 kilograms (3,000 pounds), this truck can haul everything from ATVs and side-by-sides to bed storage systems, drop-in campers, and trailers. The diesel's massive torque output ensures confident pulling power even on steep grades or loose surfaces.

For the first time, the Power Wagon diesel can be optioned with fifth-wheel and gooseneck preparation, expanding its utility for both work and recreation. The Towing Technology Group and Tow Technology Plus Group add advanced features like Trailer Reverse Guidance, Trailer Tire Pressure Monitoring System, Digital Rearview Mirror 3.0, and Trailer Reverse Steering Control. These technologies make towing large trailers more manageable and less stressful, whether you're backing up a fifth-wheel camper or maneuvering a gooseneck livestock trailer.

Powerful Presence and Iconic Styling

The 2027 Ram Power Wagon with Cummins turbo diesel is available in a 4x4 crew cab configuration with a six-foot, four-inch bed. The truck's aggressive exterior design features function and performance for an instantly recognizable look. Standard features include an aggressive sport performance hood, functional wheel arch extensions that protect the fenders and body from trail damage, and standard Power Wagon bedside graphics. Satin Black accents, including Cummins badging on the front fenders, announce the diesel's presence.

Optional exterior upgrades include body-colour door handles, extended LED lighting for the cab and bed, heated power convex trailer tow mirrors with power-folding, power-telescoping, and memory functionality, and the RamBox cargo management system for added secure storage during outdoor adventures.

Class-Leading Comfort and Technology

Inside, the 2027 Ram Power Wagon with Cummins turbo diesel offers the same premium interior found across the Ram Heavy Duty lineup. Premium materials and craftsmanship are evident throughout the cabin. A heated cloth bench seat is available as standard, with the option to upgrade to heated and ventilated leather-trimmed bucket seats. The Power Wagon Level 2 Equipment Group adds extended leather touchpoints for an elevated experience, including the grab handles and column shifter.

Standard technology includes a 12-inch Uconnect 5 touchscreen infotainment system, integrated trailer brake controller, ParkView rear backup camera with dynamic gridlines, and ParkSense front and rear park assist. Advanced safety features such as Adaptive Cruise Control, Blind-spot Monitoring with trailer coverage, Pedestrian Detection, and Rear Cross Path Detection also come standard.

Optional upgrades include a 14.5-inch Uconnect 5 touchscreen infotainment system (the largest in the heavy-duty segment), Front Passenger Interactive Display, trailer tow and off-road info pages, and premium amplified audio systems from Alpine (9-speaker) or Harman Kardon (17-speaker). These features ensure that even on the most remote trails, drivers and passengers enjoy modern connectivity and entertainment.

A Legacy of Capability

The Power Wagon nameplate debuted in 1945 and remained in production through 1980. Early trucks were based on the Weapons Carrier (WC) series of Dodge three-quarter-ton military-use trucks built during World War II. The Power Wagon went on to become a well-known civilian vehicle and continued the lineage of Dodge four-wheel-drive trucks from the 1930s, proving basic four-wheel-drive design concepts and serving as a predecessor to the many four-wheel-drive trucks in modern use today. The iconic truck was reintroduced in 2005 and now exists as an independent model.

Bringing the Cummins turbo diesel to the Power Wagon is the latest milestone in this storied history, pairing proven diesel power with unmatched towing capability, extended range, and off-road performance for customers who wish to push further into the unknown.
