Frequently asked questions
It uses a 6.7-liter Cummins High-Output turbo-diesel producing approximately 430 hp and 1,075 lb-ft of torque. It is paired with an 8-speed TorqueFlite HD automatic transmission.
Ram states that it can tow nearly 9,070 kg when properly equipped, including a 5th-wheel or gooseneck hitch. With its 117-liter fuel tank, the approximate range is up to 965 km.
The factory front winch is absent because space is needed for intercooler and radiator components. The article also states that the diesel’s added weight may affect dynamics and suspension under heavy conditions.
American manufacturer Ram has, for the first time in the history of the popular Power Wagon trim, offered it with a Cummins diesel engine. This is a significant update for a heavy truck traditionally associated with serious off-road capability and work-oriented functionality.
New Cummins diesel – power and torque
6.7-liter turbo-diesel
Under the hood sits a 6.7-liter Cummins High-Output turbo-diesel engine:
Power: ~430 hp
Torque: 1 075 lb-ft
The engine is paired with an 8-speed TorqueFlite HD automatic transmission and a rear axle with a 3.42:1 ratio — optimized for low-end revs and pulling power.
Such a powerful diesel makes the Power Wagon more capable for towing and moving heavy loads compared with the previous Hemi gasoline version.
Towing performance and range
Towing capacity
Ram states the diesel Power Wagon can tow nearly 9,070 kg when properly equipped (including a 5th-wheel/gooseneck hitch).
Driving range
Fitting a 117-liter fuel tank provides an approximate range of up to 965 km — a notable advantage for long trips and expeditions.
Off-road and structural features
The Power Wagon Diesel retains the model’s traditional off-road equipment:
Electronic locking front and rear differentials.
High-performance Bilstein shocks.
Underbody protection and reinforced suspension.
Five-link rear coil spring suspension.
Disconnectable front stabilizer bar to improve traction on difficult terrain.
However, adding the diesel required compromises: the factory winch is absent due to lack of space for the intercooler and radiator elements, which has sparked active discussion among enthusiasts.
Price, trims and market timing
Base price: about $88,470 USD (including delivery).
Market launch: second half of 2026 as a 2027 model.
Available only as a Crew Cab with a short bed.
The Power Wagon Diesel is positioned as a flagship heavy pickup — expensive, aimed at serious work, towing and off-road adventures.
What changed compared to the gasoline version
Diesel advantages
Significantly higher torque than the gasoline Hemi (~429 lb-ft from the 6.4 V8).
Better suited for towing heavy loads and expeditions.
Wider operating range.
Drawbacks and compromises
No factory winch on the front bumper.
Increased weight affects dynamics and possibly suspension under heavy conditions.
Conclusion
The new Ram Power Wagon Diesel 2027 is a win for brand fans and a long-awaited combination of the legendary Cummins diesel with extreme off-road capability. It pairs enormous torque, high towing capacity and long range, but does so at the cost of sacrificing some traditional elements (for example, the factory winch).
