2027 Ram Power Wagon Adds Diesel Option With Giant Torque
The 2027 Ram Power Wagon makes headlines in the truck world by introducing a high-output Cummins diesel engine, giving America’s toughest off-road pickup a significant boost in torque and hauling prowess. This new diesel option signals Ram’s response to long-standing customer demand for greater torque and heavy-duty performance in its flagship off-road truck.
This marks the first time the Power Wagon lineup offers a diesel, moving away from its traditional HEMI gasoline power to deliver a torque figure that challenges class rivals and sets new benchmarks for off-road-ready pickups.
What Makes the 2027 Ram Power Wagon Diesel Special
Introduction of Cummins Diesel Power
For model year 2027, Ram has equipped the Power Wagon with a 6.7-liter Cummins high-output turbo diesel inline-six engine that cranks out 430 horsepower and a best-in-class diesel torque of 1,075 lb-ft.
That massive torque figure surpasses key competitors in the heavy-duty off-road pickup segment, giving the Power Wagon a serious edge for low-speed crawling, trail articulation, and heavy hauling.
Advanced Off-Road Hardware
Ram hasn’t skimped on rugged capability. The diesel Power Wagon comes standard with advanced off-road hardware, including:
• Electronic locking front and rear differentials
• Bilstein performance shocks
• Class-exclusive disconnecting front stabilizer bar
• Mopar® rock rails and underbody protection

These systems work in unison to deliver confidence on rough trails and challenging terrain.
Towing, Payload, and Heavy-Haul Capability
One of the most compelling improvements with the Cummins diesel Power Wagon is its ability to handle heavy loads and tough jobs.
Towing and Payload Stats:
• Tow capacity: Nearly 20,000 pounds competitive with top heavy-duty pickups.
• Payload: Approaches 3,000 pounds, while maintaining off-road readiness.
This towing muscle is especially useful for fifth-wheel and gooseneck setups, now supported with factory-ready prep packages a first for the Power Wagon.
Engine Pairing and Efficiency
The Cummins diesel pairs with a TorqueFlite HD eight-speed automatic transmission and a 3.42 rear axle ratio, designed to optimize torque delivery and towing performance across gear ranges.
This combination also improves fuel efficiency over long hauls, helping the truck achieve an estimated 600-mile range on its standard 31-gallon fuel tank a boon for overlanders and long-distance adventurers.
Off-Road Credentials and Trail Performance
While the diesel variant’s added weight focuses on towing and torque, Ram has kept the Power Wagon’s trail prowess intact with the following:
• 34-inch all-terrain tires mounted on rugged 20-inch wheels.
• Ground clearance of roughly 13.2 inches, supported by generous approach, breakover, and departure angles.
• Class-exclusive suspension tech, including optional automatic-leveling rear air suspension.
These features preserve the Power Wagon’s hardcore off-road soul while adding serious hauling potential.
Interior and Tech: Rugged Meets Refined
Inside, the diesel Power Wagon shares many elements with Ram’s Heavy Duty lineup, offering comfort and technology tailored to both work and leisure.
Available features include:
• Large Uconnect infotainment screens (up to 14.5 inches).
• Optional front passenger display for navigation and trail data.
• Premium audio systems from Alpine or Harman Kardon.
• Heated and ventilated seating options for long rides.
These amenities balance rugged capability with daily comfort for owners who use their truck both on and off the road.
Pricing and Arrival Timeline
Ram confirms the 2027 Ram Power Wagon diesel will reach dealerships in the second half of 2026, with a starting price of about $88,470 (including destination charges).
While more expensive than the gas-powered version, this diesel model adds torque, haul capacity, and range that many buyers have long asked for — essentially creating a new heavyweight contender in the off-road truck market.
How It Compares: Diesel vs. Gas Power Wagon
Before the diesel option, the Power Wagon was limited to a 6.4-liter HEMI gasoline V-8, which delivered robust power but lacked the torque needed for extreme towing and heavy-haul work.
With the Cummins diesel now available:
Diesel Advantages:
• Far greater torque for towing and hill climbing.
• Better long-distance efficiency for remote travel.
• Enhanced heavy-load performance with factory-ready towing packages.
This shift reflects a broader trend among off-road and heavy-duty pickups where low-end torque and diesel efficiency are premium selling points.

Final Word
The 2027 Ram Power Wagon with its High-Output Cummins turbo diesel engine rewrites the playbook for what an off-road heavy-duty pickup can do.
