For years, heavy-duty truck enthusiasts have demanded a diesel engine in the Ram Power Wagon, only to be thwarted by strict packaging constraints. With the 2027 Ram Power Wagon Cummins, the automaker has finally delivered, sacrificing the truck's signature factory winch to make room for the massive cooling requirements of a compression-ignition powertrain. While Ram engineers note that the winch could return if they manage to reroute the plumbing, the current trade-off brings a highly anticipated diesel option to one of the market's most capable off-road platforms.
The powertrain upgrade requires a significant financial commitment. Buyers will need to spend an additional $12,995 for the 6.7-liter Cummins turbo diesel, which produces 430 horsepower and a staggering 1,075 lb-ft of torque. This engine is paired with a 3.42:1 axle ratio and pushes the Gross Vehicle Weight Rating (GVWR) past 11,000 pounds. Despite the heavy-duty chassis, early testing of the 2027 prototypes reveals a truck that rides beautifully and feels confidently over-braked, avoiding the harsh ride often associated with unladen heavy-duty trucks.
Uncompromised Off-Road Hardware
Even without the winch, the 2027 model retains the comprehensive package that made the Power Wagon famous. It features electronic locking differentials on both the front and rear axles, a push-button sway bar disconnect, and factory 34-inch tires. This aggressive setup provides 13.2 inches of ground clearance, a 26.1-degree approach angle, a 26-degree departure angle, and a 20.6-degree breakover angle.
Despite its dedicated off-road focus, the truck maintains a highly capable maximum towing capacity of 19,630 pounds. On the road, the Cummins engine idles smoothly in stop-and-go traffic but delivers its massive torque instantly when pushed. The only notable downside for traditionalists is the absence of the classic Hemi V8 exhaust note, replaced by the steady hum of the diesel.

The Six-Figure Diesel Off-Road War
Ram is effectively playing catch-up in a highly lucrative, albeit niche, segment of the heavy-duty market. Ford has already established a strong foothold with the Super Duty Tremor equipped with the Power Stroke, while GM offers Duramax variants of its heavy-duty ZR2 and AT4X off-road trucks. By finally integrating the Cummins into the Power Wagon, Ram eliminates the primary reason buyers were defecting to its Detroit rivals.
However, with as-tested prices easily breaching the $106,000 mark, these vehicles are rapidly transitioning from utilitarian workhorses to luxury lifestyle statements. The loss of the winch is a notable compromise for purists, but the sheer towing capability and low-end torque of the diesel will likely make it the default choice for buyers. Ultimately, this truck is designed for owners who spend more time hauling heavy loads on the highway than navigating tight rock-crawling trails.
