2027 Ram Power Wagon Diesel Review: Cummins Torque Meets Hardcore Off-Road Capability

The 2027 Ram Power Wagon Diesel marks a major milestone for the Power Wagon nameplate by pairing Ram’s most off-road-focused heavy-duty pickup with the legendary 6.7-litre Cummins High-Output turbo diesel. After years of customer demand, Ram finally delivers a factory Power Wagon diesel, producing 430 horsepower and a best-in-class base torque figure of 1,075 lb-ft. This powertrain transforms the Power Wagon into a true long-range, high-torque overlanding and towing machine while preserving its reputation as the most off-road-capable full-size pickup on the market. A new 3.42 rear axle ratio, paired with the TorqueFlite HD eight-speed automatic transmission, optimizes low-gear torque delivery for towing and off-road control while improving highway efficiency and reducing noise and vibration at cruising speeds. Combined with a standard 31-gallon fuel tank, the diesel Power Wagon delivers an estimated driving range of roughly 600 miles, a key advantage for remote travel and extended off-grid use. The truck arrives in the second half of 2026 with a starting price of $88,470, including destination in the US, positioning it as a premium halo product within Ram’s heavy-duty lineup. Canadian pricing will be announced at a later date. 

Mechanically, the diesel Power Wagon retains all the hardware that defines the model’s off-road dominance. It features solid front and rear axles with class-exclusive electronic locking differentials, Bilstein monotube shocks, extensive underbody skid plating, and a disconnecting front stabilizer bar that allows maximum axle articulation on technical terrain. The rear suspension continues to use Ram’s class-exclusive five-link coil setup instead of traditional leaf springs, balancing payload capability with superior ride comfort and articulation. For the first time, buyers can also option Automatic-Levelling Rear Air Suspension, further improving ride quality, load control, and trailer hookup convenience. Ground clearance reaches 13.2 inches, with approach and departure angles exceeding 26 degrees, supported by standard Mopar rock rails and trail-ready body protection. Rolling stock consists of 20-inch Satin Black wheels wrapped in 34-inch all-terrain tires, while axle upgrades include reinforced rear shafts and heavy-duty ring-and-pinion hardware designed to handle the diesel’s massive torque output. Together, these elements allow the Power Wagon Diesel to bridge a rare gap between serious off-road capability, extended-range exploration, and near-20,000-pound towing capacity, a combination previously unavailable in the Power Wagon lineup.

Inside, the 2027 Ram Power Wagon Diesel delivers what Ram positions as the most premium interior in the heavy-duty segment, blending durability with comfort and advanced technology. Buyers can choose between a practical heated cloth bench or upgrade to heated and ventilated leather-trimmed bucket seats, with the Level 2 Equipment Group adding extended leather touchpoints throughout the cabin. Standard technology includes a 12-inch Uconnect 5 touchscreen, integrated trailer brake controller, surround safety systems, and advanced driver-assistance features such as adaptive cruise control, blind-spot monitoring with trailer coverage, and pedestrian detection. Optional upgrades expand the tech experience further with a best-in-class 14.5-inch touchscreen, a front passenger interactive display, detailed off-road and towing data pages, and premium audio systems from Alpine or Harman Kardon. Towing technology is a major focus, with available 360-degree cameras, trailer reverse guidance, trailer tire pressure monitoring, and for the first time on a Power Wagon diesel, fifth-wheel and gooseneck preparation. This evolution respects the Power Wagon’s heritage dating back to 1945 while redefining its role for modern buyers who demand uncompromised off-road capability, diesel torque, and high-end comfort in a single vehicle. The result is a Power Wagon that honours its legacy while expanding its utility well beyond the trail, into work, travel, and long-distance adventure.

In conclusion, the 2027 Ram Power Wagon Diesel finally delivers what enthusiasts have been asking for by combining the Cummins High-Output turbo diesel with the Power Wagon’s unmatched off-road hardware. The result is a truck with exceptional torque, long-range capability, and serious trail performance, without sacrificing towing, comfort, or technology. It respects the Power Wagon’s heritage while expanding its role into a true do-it-all heavy-duty pickup, built for work, adventure, and long-distance travel.
