Introduction
The 2025 RAM 2500/3500 Crew Cab II, specifically the 2500 model equipped with the 6.7-liter Cummins HO diesel and TorqueFlite automatic, builds upon the established DT generation introduced in 2019. The facelift for 2025 brings cosmetic and technological updates, but the core strength of this truck remains its robust powertrain and heavy-duty capabilities. This variant occupies a sweet spot in the lineup, offering a significant power upgrade over the base gasoline engines while remaining more accessible than the even more potent Cummins Super Duty option. It’s designed for owners who frequently tow large trailers, haul heavy loads, or require a truck that can handle demanding work conditions with relative ease.
Powertrain & Engine Architecture
At the heart of this RAM 2500 is the Cummins 6.7L inline-six diesel engine, designated as the HO (High Output) variant. This engine, identified by its specific engine code, utilizes a cast iron block and aluminum cylinder head. The HO version differentiates itself from the standard Cummins through the use of a larger turbocharger and revised fuel injection settings, resulting in the increased 430 horsepower and substantial 1458 Nm (1075 lb-ft) of torque. The engine employs a Bosch common rail direct fuel injection system, delivering fuel at extremely high pressures for optimized combustion. The valvetrain utilizes an overhead valve (OHV) configuration, known for its durability and simplicity. The TorqueFlite 8-speed automatic transmission is specifically calibrated to handle the engine’s immense torque output, providing smooth and efficient gear changes. This transmission features electronically controlled shifts and a robust internal design to withstand the stresses of heavy-duty operation.
Driving Characteristics
The 6.7L Cummins HO with the TorqueFlite automatic delivers a driving experience characterized by immense pulling power and a surprisingly refined demeanor for a heavy-duty truck. The 8-speed transmission helps keep the engine within its optimal power band, even when towing or hauling. While not as quick off the line as gasoline-powered trucks, the Cummins provides a relentless surge of torque from low RPMs, making it ideal for demanding tasks. The automatic transmission’s gear ratios are well-suited for both on-road cruising and off-road crawling. Compared to the standard Cummins or the gasoline engine options, this variant offers significantly more capability, but it comes with a slight trade-off in fuel economy. The ride quality, while firm due to the heavy-duty suspension, is reasonably comfortable, especially in the Crew Cab configuration.
Equipment & Trim Levels
The 2500 6.7L Cummins HO 4×4 is typically offered in higher trim levels such as Laramie, Longhorn, and Limited. Standard equipment generally includes features like a large touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, premium cloth or leather upholstery, heated and ventilated front seats, a premium sound system, and a suite of advanced safety features. Optional extras can include a panoramic sunroof, upgraded leather interiors, a rear-seat entertainment system, and various towing packages. The interior design emphasizes comfort and functionality, with ample storage space and user-friendly controls.
Chassis & Braking
The RAM 2500/3500 utilizes a robust chassis designed to withstand the stresses of heavy-duty use. The front suspension features coil springs and a rigid axle with a transverse stabilizer bar, while the rear suspension employs a similar configuration. This setup provides a good balance of ride comfort and load-carrying capacity. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power even when heavily loaded. An Anti-lock Braking System (ABS) is standard. Steering is accomplished via a hydraulic power steering system, offering a responsive and precise feel.
Market Reception & Comparison
The RAM 2500/3500 with the 6.7L Cummins HO has consistently received positive reviews from automotive critics. It’s praised for its powerful engine, smooth transmission, comfortable ride, and well-appointed interior. Compared to competitors like the Ford Super Duty and Chevrolet Silverado/GMC Sierra HD, the RAM often stands out for its refined driving experience and upscale interior. Fuel economy, while not a primary concern for heavy-duty truck buyers, is generally competitive within its class. Reliability has been generally good, although diesel engines can be more complex and potentially more expensive to maintain than gasoline engines.
Legacy
The 6.7L Cummins engine has established a strong reputation for durability and longevity. Properly maintained, these engines can easily exceed 200,000 miles. The TorqueFlite 8-speed automatic transmission has also proven to be a reliable unit. On the used car market, RAM 2500/3500 models equipped with this powertrain hold their value well, reflecting their capability and reputation for dependability. The 2025 facelift further enhances the appeal of this truck, ensuring its continued relevance in the heavy-duty pickup segment.
