2027 RAM HD Power Wagon finally gets the Cummins HO, and it is getting people talking

With the 2027 RAM Power Wagon, the manufacturer finally answers a request many drivers have made for a long time: offering this legendary truck with the high-output 6.7 L Cummins turbo diesel.

This engine adds exactly what you’re looking for in an HD truck built for our reality here:

• It combines the Power Wagon's proven off-road capability with the concrete advantages of diesel.
• It delivers more torque, better range, and more ease for towing.
• It maintains its key hardware such as locking differentials, Bilstein shocks, a disconnectable front sway bar, underbody protection, and hill descent control.
• For 2027, it also adds important towing assets that include fifth-wheel and gooseneck prep, an available rear self-levelling air suspension, a TorqueFlite HD 8-speed automatic transmission, a 117 L tank, and an estimated 966 km range.

What the Cummins HO really changes on the 2027 RAM Power Wagon

The big change is torque.

With the 6.7 L Cummins HO turbo diesel, the 2027 RAM Power Wagon delivers strong torque from just above idle. The engine yields 430 horsepower, and especially 1,075 lb-ft of torque. That’s a huge help when pulling away with a load, keeping pace with a trailer, and climbing a hill without constantly digging into the accelerator.

On the road, you get a calmer truck. More composed. More confident.

With a camper, a jobsite trailer, or equipment behind you, the diesel works hard without needing to rev high. The TorqueFlite HD 8-speed automatic transmission also helps keep power in the right place. The result is a stronger, more predictable response, especially when the truck is loaded.

The Power Wagon maintains its off-road character. Locking differentials, Bilstein shocks, underbody protection, hill descent control, and a disconnectable front sway bar: the DNA stays. The Cummins HO adds what you need if you also want to tow heavy, drive long distances, and get work done with your truck.

In Quebec, this setup becomes especially interesting when your truck must work hard often. With an enclosed trailer, a camper, or equipment to pull, the Cummins HO gives your 2027 Power Wagon more reserve, more range, and more confidence when you work tirelessly.

2027 RAM HD Power Wagon: a work truck that is not just for show

The 2027 RAM Power Wagon was already built to take a beating. It keeps the elements that make its off-road reputation, including front and rear electronic locking differentials, Bilstein shocks, full underbody protection, hill descent control, and a disconnectable front sway bar.

With the arrival of the 6.7 L Cummins HO turbo diesel, RAM now adds 430 horsepower and 1,075 lb-ft of torque to that foundation. For you, that means a truck that strains less when it pulls, responds with more reserve at low rpm, and keeps its composure as the load gets heavier.

RAM also adds two important towing upgrades. The Power Wagon gains for the first time fifth-wheel and gooseneck prep. A rear self-levelling air suspension will also be available. If you tow a trailer often, these are additions that matter.

They matter because fifth-wheel and gooseneck prep places the weight of certain trailers directly over the rear axle, which helps your truck better control a heavy load. The self-levelling air suspension then helps keep the truck more level and more stable when the rear is loaded.

The 117 L tank and the estimated 966 km range also give you more freedom on long trips, especially when you drive far from major urban centres. Inside, the 2027 Power Wagon adds an even more upscale presentation to the already impressive cabin with Uconnect 5 and a 14.5-inch touch screen. These features are part of the many RAM truck technologies designed to improve comfort, driving and day-to-day work.

The result is clear. The 2027 RAM Power Wagon diesel keeps its real off-road tools, adds diesel torque, and becomes even more appealing for drivers who want to tow, work, and go the distance with the same truck.

Cummins HO vs. base engine: which one should you choose for your use

Do you tow more than 15,000 lb. regularly? Read this.

The Cummins HO is for you as soon as you use your truck for real loads, whether that is a big camper, an enclosed trailer, or jobsite equipment. Same thing if you do long trips with weight behind you. In that kind of use, the 1,075 lb-ft of torque becomes a true advantage because the engine works hard at lower rpm.

You will feel it most when taking off, on hills, and when the truck has to keep its pace with a heavy trailer. The Cummins HO gives you more reserve, makes the drive more composed when your truck is loaded, and helps you travel farther comfortably. You also enjoy great freedom thanks to the 117 L tank and an estimated 966 km range.

The base engine can still suit you if your use is lighter, such as for daily commuting, a small trailer, occasional jobs, or weekends at the cabin without a heavy load. In that case, you may not need to pay for all the strength of diesel. If your needs are lighter and you don’t require the capabilities of an HD truck, the 2027 RAM 1500 may also be a better fit for everyday driving.

But if your truck serves for work, for towing often, or for long trips with a serious load, the Cummins HO becomes the logical choice.

What RAM fans had been waiting for

The Power Wagon has always been an off-road champion. But if you are a RAM fan, especially in a top-end trim, it is normal to expect your truck to meet all your needs, not just luxury. Here, what was missing was the 1,075 lb-ft torque of the Cummins HO.

The high-output diesel adds what many customers wanted for work, towing, and long distances.

It becomes an even bigger asset if you use your truck for work during the week, then for your weekend off-road adventures when you want to unwind.

That is why RAM drivers were waiting for it with such impatience. The wait is over, and RAM finally delivers the pinnacle of a luxury truck that can also do it all.
