As the off-road heavy-duty truck market evolves, Ram aims to maintain its long-standing dominance amidst new contenders such as the Chevy Silverado HD ZR2 and the revamped Ford Super Duty Tremor. The company introduces significant updates with the launch of the 2025 Ram 2500 Power Wagon and Rebel HD, focusing on design, technology, and performance enhancements, particularly for the Rebel HD.
After testing the 2025 Power Wagon, it is clear that it continues to excel with exceptional off-road features designed for rugged terrains. Meanwhile, the Rebel HD enhances its competitiveness, particularly with the addition of an upgraded turbodiesel engine, which strengthens its position in the market. However, the Rebel HD’s suspension may be less forgiving, a consideration for some potential buyers.
Power Wagon and Rebel HD: Key features
2025 Ram 2500 Power Wagon
The 2025 Ram 2500 Power Wagon remains equipped with a conventional 6.4-liter V-8 engine, producing 405 horsepower and 429 lb-ft of torque. While this powertrain is reliable, it appears somewhat outdated in comparison to the more modern and powerful 7.3-liter V-8 offered by Ford. Notably, the Power Wagon does not provide a turbodiesel option, reserving that feature exclusively for the Rebel HD.
The Rebel HD presents a more robust option with an available 6.7-liter Cummins inline-6 turbodiesel engine. This engine significantly enhances its appeal, especially for buyers prioritizing towing and hauling capabilities. It generates 430 horsepower and an impressive 1,075 lb-ft of torque, surpassing the Chevy’s 975 lb-ft but lagging behind Ford’s 1,200 lb-ft. The 2025 updates include a new turbocharger and improved oil filtration systems, leading to faster acceleration and easier maintenance.
Performance enhancements
With the introduction of a new 8-speed automatic transmission, the acceleration of the Rebel HD has improved, achieving 0-60 mph in 6.9 seconds, down from 8.0 seconds in previous models. The smooth shift transitions, especially while towing, enhance the overall driving experience, which is crucial for users reliant on their trucks for heavy lifting.
Driving experience and off-road capability
While competitors offer turbodiesel engines, Ram Heavy Duty Chief Engineer, Doug Killian, acknowledged the demand for a turbodiesel option in the Power Wagon. However, engineering challenges, particularly with fitting the engine alongside the Power Wagon’s suspension, have so far prevented this option from materializing. Nevertheless, the Ram team remains aware of the competitive landscape and the requests from Power Wagon buyers.
Both trucks deliver distinct driving experiences. The Power Wagon features a suspension system designed for a smoother ride, utilizing softer Bilstein shocks that excel in off-road conditions. In contrast, the Rebel HD’s stiffer suspension prioritizes towing capacity and load handling. This difference becomes apparent on rough terrains, where the Power Wagon maintains better traction, while the Rebel HD may experience wheel spin.
A recent off-road excursion in Nevada’s Old Kingman Highway Recreational area highlighted these distinctions. The Power Wagon demonstrated superior traction and control over challenging obstacles, whereas the Rebel HD faced difficulties due to its absence of an electronic disconnecting front sway bar and front locker.
Design and interior upgrades
Regarding aesthetics, the 2025 models showcase a refreshed appearance, particularly at the front. The redesigned headlights and grilles enhance the trucks’ intimidating presence, though the changes may not appeal to all. While the rear of the trucks has been streamlined for simplicity, the Power Wagon continues to feature unique elements such as standard front and rear electronic locking differentials and a winch.
Inside, the cabins of the Ram HD trucks remain user-friendly and luxurious, with the option for a larger 14.5-inch touchscreen. This modern interface retains the practicality of physical buttons. The introduction of a column-mounted electronic gear selector has been a welcomed change, addressing customer feedback for a more traditional feel.
Pricing and market positioning
