It was a long time coming, but the Ram Power Wagon is finally available with a Cummins diesel. The heavy-duty adventure pickup has long been a favorite among four-wheelers, but up to now, the 6.4-liter Hemi V8 gasser was the only engine option. We already knew that was changing for the 2027 model year, but we weren't sure how much it would cost until Ram announced the starting price Monday morning. If you just have to buy one, be prepared to spend at least $89,560.That price includes the destination fee, but it isn't the absolute most you can spend on a Power Wagon with the 6.7-liter Cummins. The engine is a $12,995 option on its own, and if you want the Level 2 equipment group, you'll have to fork over another $8,545. Don't be surprised if you see diesel Power Wagons on the dealer lot for $100,000 or more.Of course, it's arguably the most unstoppable truck out there, now with more work capacity than ever. Ram says the three-quarter-ton Power Wagon can now tow 19,630 pounds with the compression-ignition powerplant, and max payload is rated at 2,930 pounds. For reference, the Cummins makes 430 horsepower and 1,075 lb-ft of torque. All of that is mighty impressive for a machine that has locking differentials front and rear, a push-button sway bar disconnect, and factory 34-inch tires.Byron HurdRam didn't just toss the Cummins into the existing Power Wagon and say, "That'll do." It fitted even more skid plating underneath the truck to protect the diesel exhaust fluid tank, as well as the fuel tank and the transfer case. And with 31 gallons of diesel, it should be able to go more than 600 miles between fill-ups.AdvertisementAdvertisementI bet we'll see more diesel Power Wagons on the trails than gas-powered ones going forward, even with the higher price. Modern pickup drivers love to own the most extreme version of their truck, and it's hard to resist the Cummins if you have the money for it. Just remember that if you spring for the optional engine over the gas V8, you lose the factory winch. These things are hard enough to keep cool without a massive spool blocking the radiator.Got a tip or question for the author? Contact them directly: [email protected]
