The First Ever Ram Power Wagon with the Legendary Cummins Diesel

It has been a long-requested combination, and as of January 1, 2026, Ram has officially announced the first-ever factory Ram Power Wagon equipped with the 6.7L Cummins Turbo Diesel.¹

While the Power Wagon has been an off-road icon since 1945, it was historically restricted to gasoline engines (most recently the 6.4L HEMI V8) because the massive cooling requirements of the diesel engine left no room for the Power Wagon's signature front-mounted winch.² For the upcoming model year, Ram has finally prioritized diesel torque over the factory winch to create this new variant.³

The 2027 Ram Power Wagon Diesel

Technically debuting for the 2027 model year, this truck is scheduled to hit showrooms in the second half of 2026.⁴ It bridges the gap between the heavy-duty towing of a standard 2500 and the extreme rock-crawling capability of the Power Wagon.

Key Performance Specs

• Engine: 6.7L High-Output (HO) Cummins Turbo Diesel I6.⁵

• Power: 430 Horsepower.⁶

• Torque: A best-in-class 1,075 lb-ft of torque.⁷

• Towing: Maximum capacity of nearly 20,000 lbs (a massive jump from the gas-powered version).⁸

• Transmission: 8-speed TorqueFlite HD automatic.⁹

Off-Road Hardware

Despite the heavier engine, Ram has kept the core features that make it a "Power Wagon":

• Locking Differentials: Electronic front and rear lockers (the front axle was specially re-engineered to handle the diesel's weight and torque).¹⁰

• Sway Bar Disconnect: The class-exclusive electronic front sway bar disconnect remains for maximum articulation.¹¹

• Suspension: Bilstein monotube shocks and a five-link coil rear suspension.¹²

• Protection: Integrated underbody skid plates for the fuel tank, transfer case, and DEF tank.¹³

The "Big Compromise"

To fit the High-Output Cummins and its necessary cooling modules (intercooler and radiator), the factory-installed Warn winch has been removed.¹⁴ Ram engineers stated that the cooling required for 1,075 lb-ft of torque made the winch packaging impossible from the factory, though they expect many owners will turn to the aftermarket for winch solutions.

Pricing & Availability

• MSRP: Starting at $88,470 (including destination).¹⁵

• On-Sale Date: Expected in late 2026.¹⁶
