On January 1, 2026, in Auburn Hills, Michigan, Ram revealed the first Power Wagon equipped with a Cummins turbo diesel engine, marking a historic step in the brand’s off-road pickup lineup.
The launch of the 2027 model was presented through the short film “Resurrection,” hosted by Tim Kuniskis, head of the American brands, SRT Performance division, and Ram’s marketing and retail strategy.
At the heart of the update is the acclaimed 6.7-liter Cummins HO engine, an inline six-cylinder turbo diesel delivering 430 horsepower and 1,075 lb-ft of torque, positioning the Power Wagon as the diesel torque leader in its class. Despite the new powertrain, Ram claims the model retains its title as the most capable full-size off-road pickup.
Cummins in the Power Wagon: a long-standing customer request
According to Kuniskis, the addition of the Cummins engine responds to a long-standing customer demand. The goal is to combine the durability of the diesel powertrain with the model’s extreme off-road capabilities, increasing range, towing capacity, and performance on trails and harsh terrain.
The Ram Power Wagon with Cummins turbo diesel will reach the market in the second half of 2026, starting at US$ 88,470, including shipping.
Built for trails and heavy-duty work
Like the gasoline version, the diesel Power Wagon features underbody skid plates protecting the DEF tank, fuel tank, and transfer case. The package includes 20-inch satin black wheels fitted with 34-inch all-terrain tires.
The model retains front and rear solid axles with electronically locking differentials, exclusive in its category. Manufactured by American Axle Manufacturing, the axles measure 9.25 inches front and 11.5 inches rear, with a 3.42:1 ratio, along with reinforced 38 mm rear half shafts.
The front suspension uses a three-link system with Bilstein monotube shocks and an electronically disconnectable sway bar, allowing greater articulation on trails. At the rear, the Power Wagon adopts a five-link coil spring suspension with Bilstein components, improving comfort without sacrificing load capacity. A rear air suspension with automatic leveling is also optional.
Transmission and extended range
To fully leverage the diesel torque, the 2027 Power Wagon uses an eight-speed TorqueFlite HD automatic transmission paired with a 3.42 axle ratio. The first six gears prioritize power and towing, while the last two reduce engine RPM on the road, enhancing fuel efficiency and cabin quietness.
The 31-gallon fuel tank provides an estimated range of up to 600 miles, especially designed for overlanding and long-distance expeditions far from conventional infrastructure.
Robust design and unique configuration
The new Power Wagon with Cummins will be offered exclusively in 4×4 crew cab configuration with a 6-foot-4-inch bed. Off-road angles include 26.1° approach, 26.0° departure, 20.6° breakover, and 13.2-inch ground clearance. Standard features include Mopar rock rails to protect the cab and chassis.
Visually, the model maintains the Power Wagon’s aggressive style, with a functional sport hood, fender flares, exclusive bed graphics, satin black details, and Cummins badges on the front fenders. Optional equipment includes extended LED lighting, RamBox cargo management system, and heated towing mirrors with full power adjustments and memory.
With the introduction of the Cummins engine in the Power Wagon, Ram expands its halo model lineup, emphasizing highly specialized configurations that combine extreme off-road performance, heavy-duty capability, and extended range.
