The headline change for 2027 is one Ram fans have requested for years: the 6.7-liter Cummins High-Output turbo diesel is now available in the Power Wagon. No prior Power Wagon has offered a diesel option, making this a genuine first for the nameplate's 80-year history.
Key changes for the 2027 model year:
Cummins Diesel Arrives in the Power Wagon: The HO 6.7L I6 produces 430 hp and 1,075 lb-ft of torque, best-in-class for base diesel torque in the heavy-duty segment. Ram 2027 HD press release
New 3.42 Rear Axle Ratio:The diesel Power Wagon adopts the 3.42 axle ratio introduced on the 2025 Ram HD lineup, paired with the TorqueFlite HD 8-speed automatic. Gears one through six provide a higher final drive for confident acceleration and towing; gears seven and eight drop to a lower ratio for highway efficiency and reduced NVH.
Fifth-Wheel/Gooseneck Prep Now Available on Power Wagon: For the first time, Power Wagon buyers can add a bed-mounted 7-pin connector and mounting provisions for a fifth-wheel hitch or gooseneck ball, expanding the truck's utility beyond pure off-road use.
31-Gallon Standard Fuel Tank: The diesel Power Wagon ships with a 31-gallon tank, supporting an estimated 600-mile range on a single fill, making it a practical choice for remote overlanding or long hauls between fuel stops.
New Lunar Edition Available on Power Wagon and Rebel: A Ceramic Grey exterior with Diamond Black lower body, Gloss Black side stripe graphics, Copperhead Orange contrast stitching, and black-painted wheels are exclusive to this appearance package.
The 2027 Ram 2500 spans a wide trim ladder. The 6.4L HEMI V8 is standard on every trim; the 6.7L Cummins HO turbo diesel is available across all of them.

The Power Wagon diesel runs solid front, AAM 9.25-inch, and rear, AAM 11.5-inch, axles with electromagnetic-actuated e-lockers and 38mm rear axle shafts sized for the 34-inch tire/wheel combination.
The Ram 2500 Crew Cab provides 40.9 inches of front headroom and legroom, with 40.2 inches of rear legroom. The Mega Cab stretches rear legroom to 43.1 inches, useful for taller passengers or families spending time on long hauls. Front shoulder room measures 65.9 inches across cab styles.
Seating materials scale with trim. Tradesman and lower Big Horn levels use cloth; upper Big Horn and Power Wagon Level 1 move to Bristol leather with Axis II perforated inserts. Power Wagon Level 2 and Laramie add Natura Plus leather with Power Wagon embossment and heated/ventilated bucket seats. The Limited Longhorn and Limited each deliver the most refined interior in the segment, with premium full-leather door panels and extended leather touchpoints distinguishing both top trims from everything below them.
The standard bed on the crew cab Power Wagon measures 6 feet 4 inches, 76.3 inches at the floor. An 8-foot bed is available on Regular Cab and Crew Cab configurations for maximum payload flexibility. The available RamBox cargo management system adds locking, weatherproof storage in the bedsides, standard on both the Limited Longhorn and Limited trims.
Screen size scales from an 8.4-inch Uconnect unit on base Tradesman configurations up to the available 14.5-inch Uconnect 5 touchscreen, the largest touchscreen in the heavy-duty truck class. The 12-inch Uconnect 5 is standard on the Power Wagon and Big Horn, via equipment group, while the 14.5-inch screen is standard on both the Limited Longhorn and Limited and available on Power Wagon Level 2, Rebel Level 2, and Laramie Level 2.
Audio options run from a base 6-speaker system through an Alpine 9-speaker setup to the 17-speaker Harman Kardon system with subwoofer. The Power Wagon Level 2 and upper Rebel, Laramie, Limited Longhorn, and Limited trims can be specified with the Harman Kardon system.
Towing technology is a key differentiator. The available Tow Technology Group adds a 360-degree surround camera, cargo-view camera, trailer reverse guidance, and trailer tire pressure monitoring. The Tow Technology Plus Group goes further with a digital rearview mirror 3.0 and Trailer Reverse Steering Control, which actively steers the truck while backing a trailer. A class-exclusive front passenger interactive display is available on Power Wagon Level 2 and upper trims.
Available automatic-leveling rear air suspension is offered on Rebel, Laramie, Limited Longhorn, and Limited trims.
Ram Uconnect 5 features explained
Standard safety on the Power Wagon includes Blind-Spot Monitoring with trailer coverage, Pedestrian Detection, Rear Cross Path detection, adaptive cruise control, Hill Descent Control, ParkView rear backup camera with dynamic gridlines, ParkSense front and rear park assist, and an integrated trailer brake controller.
The Safety Group, available or standard depending on trim, adds Active Lane Management, Forward Collision Mitigation, Automatic Emergency Braking, Drowsy Driver Detection, Traffic Sign Recognition, and adaptive steering.
Ground clearance on the Power Wagon diesel measures 13.2 inches, with a 26.1-degree approach angle and 26-degree departure angle. The diesel Power Wagon retains the class-exclusive electronic disconnecting front sway bar and the five-link coil rear suspension with Bilstein monotube shocks.
The 2026 Power Wagon was a gas-only truck. The 2027 model changes that entirely by adding the Cummins HO diesel, a pairing the Ram community has wanted since the Power Wagon returned in 2005. Buyers who need maximum off-road articulation and the diesel torque required to haul a loaded fifth-wheel or gooseneck trailer now have a single truck that does both.
For buyers focused purely on payload, the HEMI V8 with the Payload Upgrade Package remains available, reaching 4,580 lbs of rated payload. For those prioritizing towing range and torque on long trips, the diesel's 1,075 lb-ft and estimated 600-mile tank range make it the stronger choice.
Buyers in Tuscaloosa who are weighing the 2026 versus 2027 model should note: the fifth-wheel/gooseneck prep on the Power Wagon is new for 2027 only, as is the Lunar Edition appearance package.
