In the competitive realm of heavy-duty off-road trucks, the landscape is shifting. With the recent launch of the Chevy Silverado HD ZR2 and the revamped Ford Super Duty Tremor, Ram is determined to maintain its foothold in this segment. The 2025 Ram 2500 Power Wagon and 2500 Rebel HD showcase a series of updates aimed at enhancing their off-road capabilities.
While the Power Wagon remains a standout due to its specialized off-road hardware, the Rebel HD has significantly closed the gap, thanks to major improvements in its available turbodiesel engine. However, the suspension system in the Rebel HD still requires further refinement for improved comfort.
Key specifications of the 2025 Ram models
The 2025 Ram 2500 Power Wagon continues to be powered solely by the dependable 6.4-liter V-8 engine, delivering 405 horsepower and 429 lb-ft of torque. While this engine is reliable, it lacks the modern refinement and power of Ford’s 7.3-liter Godzilla V-8. Conversely, the Rebel HD features the gas V-8 as standard but can be upgraded to the 6.7-liter Cummins inline-6 turbodiesel, appealing to those who rely on their trucks for heavy-duty work.
Performance enhancements for the turbodiesel engine
The updated turbodiesel engine in the Rebel HD has undergone considerable changes for 2025, including a new turbocharger, an advanced intake manifold, and a modernized oil filter system. Notably, the previous 6-speed automatic transmission has been replaced with an 8-speed automatic, resulting in quicker acceleration and improved cold-start performance. According to Ram, the time to reach 60 mph has decreased from 8.0 seconds to 6.9 seconds, underscoring the efficiency of the new system.
Off-road capabilities of the Ram 2500 models
While the Power Wagon is designed for optimal off-road performance, it is essential to note that it cannot currently be equipped with a turbodiesel engine, a point that has not gone unnoticed by enthusiasts. Ram’s Heavy Duty Chief Engineer, Doug Killian, acknowledged the strong demand among Power Wagon owners for a turbodiesel option, but engineering challenges have thus far prevented this from occurring.
In off-road scenarios, the Power Wagon excels with its electronic disconnecting front sway bar and front locker, features that significantly enhance traction and stability over rough terrain. During a test drive in the Old Kingman Highway Recreational area of Nevada, the Power Wagon outperformed the Rebel HD on undulating terrain, maintaining superior traction and control.
Comparison with competitors
The Rebel HD competes with offerings like the Ford Super Duty Tremor and the Chevy Silverado HD ZR2, which boast impressive towing and payload capacities. The Ford can tow up to 23,000 pounds with a gooseneck trailer, while the Silverado HD ZR2 can handle 18,500 pounds. In contrast, the Power Wagon is limited to a towing capacity of 10,530 pounds, prioritizing off-road capabilities over hauling capabilities.
Visually, the aesthetic updates for the 2025 models include revised headlights and grilles that provide a more aggressive stance. Although the new design may appear busier, it enhances the truck’s overall presence on the road. The rear taillights have also been simplified, aligning more closely with the updated Ram 1500.
Interior features and technology updates
Inside, the 2025 Ram HD models continue to impress with their luxurious interiors. A 12.0-inch touchscreen comes standard, while an optional 14.5-inch version is available, providing a digital interface that complements the truck’s modern aesthetic. Additionally, the introduction of a column-mounted electronic gear selector in all models addresses customer feedback regarding the previous rotary shift knob.
Pricing for these models reflects their updates, with the 2025 Ram Power Wagon starting at $74,235, while the Rebel HD begins at $70,740. The cost for the turbodiesel option in the Rebel HD adds an additional $12,595, indicating that buyers are investing in enhanced capabilities.
While the Power Wagon remains a standout due to its specialized off-road hardware, the Rebel HD has significantly closed the gap, thanks to major improvements in its available turbodiesel engine. However, the suspension system in the Rebel HD still requires further refinement for improved comfort.0
