Cummins Power Finally Comes To The Power Wagon

For decades, hardcore Ram loyalists have been asking the same question: Why can’t I get a Power Wagon with a Cummins? For 2027, that question finally has a clear and decisive answer. The Ram Power Wagon is now available with the legendary 6.7-liter Cummins High-Output H/O I6 turbo diesel, creating what is arguably the most capable and versatile factory-built heavy-duty off-road truck Ram has ever offered.

This isn’t a simple engine swap or a marketing exercise. The 2027 Ram 2500 Power Wagon Diesel represents a full evolution of the nameplate—one that finally blends trail-rated hardware, modern towing technology, and diesel torque into a single, no-compromise package.

Power Wagon Heritage: Born on the Battlefield –

The Power Wagon name carries real weight in truck history. It first appeared in 1945, derived directly from Dodge’s WC-series military trucks used during World War II. These early Power Wagons were rugged, no-nonsense machines designed to work in harsh environments where roads didn’t exist. Long before four-wheel drive became mainstream, Power Wagon proved its value in agriculture, construction, and remote industrial work.

Production of the original civilian Power Wagon ran through 1980, cementing its reputation as one of the toughest trucks ever built. When Ram revived the Power Wagon name in 2005, it wasn’t meant to be just another trim level. It became a standalone model focused on off-road dominance—prioritizing articulation, traction, and durability over maximum towing numbers.

For years, that philosophy meant gasoline power only. Diesel torque and heavy towing were left to other Ram HD trims. The 2027 model finally reunites the Power Wagon’s original spirit—go anywhere, do anything—with the powertrain customers have been demanding.

Cummins Powertrain: Torque Changes Everything –

At the heart of the 2027 Power Wagon Diesel is the 6.7-liter Cummins H/O. Rated at 430 horsepower and a massive 1,075 lb.-ft. of torque, it delivers best-in-class base diesel torque in the segment. That number isn’t just impressive on paper—it fundamentally changes how the Power Wagon behaves in the real world.

Low-speed crawling becomes easier and more controlled. Steep climbs require less throttle input. Deep sand, mud, and loose terrain are handled with calm authority rather than brute force. For overlanders, the diesel’s efficiency and torque curve mean fewer fuel stops and less strain when carrying gear, campers, or recovery equipment.

The Cummins is paired with the ZF Powerline-sourced TorqueFlite HD 8AP1075 8-speed automatic transmission and a 3.42 rear axle ratio. This combination provides shorter gearing in the lower gears for confident acceleration and trail work, while the upper gears reduce engine speed for highway cruising. The result is better fuel economy, reduced noise and vibration, and smoother long-distance driving.

A standard 31-gallon (117-liter) fuel tank enables an estimated driving range of up to 600 miles (965 km), making the Power Wagon Diesel particularly attractive to those who travel far off the beaten path.

Off-Road Hardware: Still the Benchmark –

Even with the added weight and torque of a diesel, the Power Wagon retains its crown as the most off-road-capable full-size pickup available from the factory. The foundation remains unchanged—and that’s a good thing.

Solid front and rear axles are equipped with electronic-locking differentials, allowing maximum traction when conditions deteriorate. A class-exclusive electronic disconnecting front sway bar allows the front axle to articulate more freely over uneven terrain, keeping tires planted where independent suspensions would lift wheels.

Ram’s five-link coil rear suspension—still unique in the heavy-duty segment—continues to separate the Power Wagon from leaf-spring competitors. It delivers improved ride quality and articulation while maintaining serious strength. Power Wagon–tuned Bilstein™ monotube shocks handle damping duties front and rear, calibrated explicitly for off-road abuse.

Ground clearance measures 13.2 inches (335 mm), supported by a 26.1-degree approach angle, 26.0-degree departure angle, and a 20.6-degree breakover angle. Mopar accessory rock rails come standard, protecting the cab and chassis when trails get tight and unforgiving.

For buyers who want added versatility, Automatic-Leveling Rear Air Suspension is now available for the first time on a Power Wagon. It maintains a level stance under load and improves ride comfort without sacrificing trail capability.

Exterior Design: Functional Aggression –

Visually, the 2027 Power Wagon Diesel looks exactly how it should—purposeful, aggressive, and instantly recognizable. A standard sport performance hood hints at the torque underneath, while powder-coated front and rear bumpers reinforce its off-road intent.

Black Power Wagon wheel flares, bedside graphics, and Satin Black accents give the truck a tough, cohesive look. Satin Black Cummins badging on the front fenders subtly signals that this isn’t a typical Power Wagon. The truck rides on 20-inch Satin Black diamond-cut aluminum wheels wrapped in 34-inch all-terrain tires, balancing trail grip with on-road stability.

Optional upgrades include LED cab and bed lighting, RamBox cargo management, body-color handles, and power-folding trailer tow mirrors—features that add everyday usability without diluting the truck’s rugged identity.

Interior: Premium, But Still Purpose-Built –

Inside, the Power Wagon Diesel benefits from Ram’s class-leading heavy-duty interior design. Even in standard form, the cabin feels substantial and thoughtfully laid out. Buyers can choose a heated cloth bench seat for a more work-focused setup or opt for leather-trimmed bucket seats with heating and ventilation.

The available Power Wagon Level 1 and Level 2 Equipment Groups further elevate the experience, adding premium leather surfaces, power-adjustable pedals with memory, LED interior lighting, dual wireless charging pads, and expanded storage solutions. The Level 2 package brings Natura leather seating, unique trim accents, and Power Wagon-specific branding throughout the cabin.

Despite the luxury, everything still feels truck-first. Controls are large and glove-friendly, storage is generous, and materials are chosen to withstand real use rather than just showroom impressions.

Technology And Safety –

Technology plays a major role in the 2027 Power Wagon Diesel. A 12-inch Uconnect 5 touchscreen comes standard, while an available 14.5-inch display dominates the center stack. Ram’s class-exclusive front passenger interactive display allows the passenger to independently manage navigation, media, and vehicle information.

Off-road and towing-specific pages provide real-time data on driveline status, pitch and roll angles, trailer setup, and camera views. Audio options range from a standard 6-speaker system to a premium 9-speaker Alpine system with subwoofer and a 17-speaker premium Harman Kardon setup.

Safety is equally comprehensive. Standard features include Adaptive Cruise Control, Hill Descent Control, Blind-Spot Monitoring with trailer coverage, Pedestrian Detection, Rear Cross Path Detection, and ParkSense front and rear park assist. Optional packages add lane management, traffic sign recognition, and advanced camera systems.

Capability: No Longer a Compromise –

Historically, Power Wagon owners accepted lower tow ratings in exchange for unmatched trail performance. The diesel changes that equation. With a towing capacity approaching 20,000 pounds (9,070 kg) and a payload near 3,000 pounds (1,360 kg), the Power Wagon Diesel finally delivers serious hauling capability alongside its off-road credentials.

For the first time, fifth-wheel and gooseneck prep is available, along with advanced towing technologies like Trailer Reverse Steering Control, Trailer Tire Pressure Monitoring, and a full 360-degree camera system. Automatic-Leveling Rear Air Suspension also introduces a Bed Lowering Mode, making trailer hookup easier and safer.

Wanna Level Up? –

Ram offers two optional equipment groups for the 2027 Ram 2500 Power Wagon Diesel, allowing buyers to add comfort, technology, and premium features while retaining the truck’s hardcore off-road capability.

Power Wagon Level 1 Equipment Group: Functional Luxury –

The Power Wagon Level 1 Equipment Group is aimed at buyers who want meaningful upgrades in comfort, technology, and daily usability without pushing the Power Wagon into full luxury territory. This package replaces the standard seating with heated bucket seats upholstered in Black Bristol leather featuring Axis II perforation and durable Gode-Tex vinyl accents. It adds a premium Alpine 9-speaker audio system with a dedicated subwoofer. It introduces full driver memory functionality, including memory for the driver’s seat, exterior mirrors, adjustable pedals, and radio presets.

Convenience and visibility are improved through premium power exterior mirrors that offer power folding, power telescoping, power adjustment, heating, auto-dimming, integrated forward and rear utility lighting, and memory capability. Power-adjustable pedals with memory further enhance driver comfort. Exterior lighting is upgraded with automatic high-beam headlamp control and front LED lamps, while rain-sensing windshield wipers improve all-weather driving confidence.

Inside the cabin, Level 1 adds extensive LED lighting throughout, including switchable LED dome lamps, an LED-lit overhead console, and LED front footwell lighting. Remote proximity keyless entry for both front doors is included, along with body-color door and tailgate handles. Rear passengers benefit from dual USB charging ports with both Type-A and Type-C connections, as well as a 115-volt, 400-watt AC power outlet.

Additional features include a factory security alarm system, Mopar rubber floor mats for the front and rear, a visor-mounted universal garage door opener, rear under-seat in-floor storage boxes, and a dual wireless smartphone charging system. Collectively, the Level 1 Equipment Group transforms the Power Wagon into a far more comfortable and technologically advanced daily driver while retaining its trail-ready capability.

Power Wagon Level 2 Equipment Group: Full Premium Experience –

The Power Wagon Level 2 Equipment Group builds on Level 1 and pushes the truck firmly into luxury territory, while still respecting its off-road DNA. This package is aimed at buyers who want their Power Wagon to feel just as upscale on the inside as it is capable on the trail.

Interior materials take a significant step forward with a premium full-leather door trim package and upgraded Natura leather bucket seats featuring Axis II inserts, contrast piping, Power Wagon embossing, and a hard badge mounted on the center console. The look and feel are noticeably richer, yet still durable enough for real truck use.

Technology is where Level 2 really separates itself. The standard 12-inch touchscreen is replaced by Ram’s massive 14.5-inch Uconnect 5 infotainment system, complete with built-in navigation, tow-specific features, HD Radio, SiriusXM, Bluetooth, and advanced voice control. A front passenger interactive display allows the passenger to manage navigation, entertainment, and vehicle data independently—something still rare in the heavy-duty segment.

Audio gets a major upgrade as well, with a 17-speaker Harman Kardon™ premium sound system that delivers clear, powerful sound whether cruising the highway or airing down at the trailhead.

Level 2 also adds meaningful functional upgrades, not just luxury touches. The included Bed Utility Group brings LED pickup box lighting, a spray-in bedliner, and a Mopar bed step, enhancing everyday usability. A Cargo View Camera with dynamic center lines improves visibility when hauling gear or backing up to a trailer.

A leather-wrapped column shifter, upgraded interior trim with aluminum litho and piano black accents, and another universal garage door opener complete the package.

In simple terms:

• Level 1 is ideal for buyers who want comfort, convenience, and technology upgrades without pushing the truck into luxury-truck pricing territory.

• Level 2 is for those who want a no-compromise Power Wagon—one that can crawl rocks, tow heavy trailers, and still feel premium enough to compete with high-end heavy-duty pickups.

Both packages stay true to the Power Wagon’s mission. They don’t soften the truck—they simply give buyers the choice to make it as comfortable and technologically advanced as they want while keeping all the off-road hardware intact.

Pricing And Availability –

The 2027 Ram 2500 Power Wagon Diesel is scheduled to arrive in the second half of 2026. Pricing starts at $88,470, including destination. While that places it firmly in premium territory, the combination of Cummins power, exclusive off-road hardware, advanced technology, and towing capability makes it a unique offering with no direct rival.

Final Thoughts –

The 2027 Power Wagon Diesel feels like the truck Ram fans have been waiting on for years. It honors the Power Wagon’s deep-rooted history while finally eliminating its biggest limitation. By combining Cummins torque, class-exclusive off-road hardware, modern towing technology, and a refined interior, Ram didn’t just evolve the Power Wagon—it completed it.
