Powertrain & Engine Architecture
The heart of this RAM 3500 is the Cummins 6.7-liter inline-six diesel engine. This engine, a mainstay of the Ram heavy-duty lineup for decades, has undergone continuous refinement. The “HO” designation signifies the High Output version, tuned for increased power. The engine utilizes a cast iron block and head, known for their durability. Fuel is delivered via a high-pressure common rail direct injection system, maximizing combustion efficiency and power output. The engine employs an overhead valve (OHV) configuration, a design choice prioritizing low-end torque and reliability. A variable geometry turbocharger with an intercooler further enhances performance. The TorqueFlite 8-speed automatic transmission is specifically calibrated to handle the engine’s substantial torque output. This transmission features electronically controlled shifts and a robust internal design, ensuring smooth and reliable operation even under heavy loads.
Driving Characteristics
The 430 horsepower and 1458 Nm (1075 lb-ft) of torque delivered by this powertrain configuration results in impressive towing and hauling capabilities. While not designed for outright speed, the 3500 DRW offers strong acceleration, particularly when unloaded. The 8-speed TorqueFlite transmission provides a wide range of gear ratios, allowing the engine to operate efficiently at various speeds. The DRW setup (dual rear wheels) significantly increases stability when towing heavy loads, reducing sway and improving braking performance. Compared to lower-output engine options (like the 6.4L Hemi V8), this Cummins HO offers substantially more torque, making it ideal for demanding tasks. Compared to the standard output Cummins, the HO version provides a noticeable increase in horsepower, though at the expense of slightly reduced fuel economy.
Equipment & Trim Levels
The 2025 RAM 3500 Regular Cab with the Cummins HO engine and DRW configuration typically comes standard with a robust set of features geared towards work and utility. These include heavy-duty suspension components, a reinforced frame, and a limited-slip differential. Interior appointments generally feature durable vinyl or cloth upholstery, with options for leather upgrades on higher trim levels (such as Laramie or Limited). Standard technology includes a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, as well as basic safety features like ABS and stability control. Optional extras include a premium sound system, navigation, heated and ventilated seats, and advanced driver-assistance systems like adaptive cruise control and lane departure warning.
Chassis & Braking
The chassis of the RAM 3500 is built around a fully boxed, high-strength steel frame designed to withstand significant stress. The front suspension utilizes a coil spring and rigid axle setup with a transverse stabilizer bar, providing a comfortable ride and good handling. The rear suspension employs leaf springs, with an optional air suspension system available for enhanced ride quality and load leveling. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power even when towing heavy loads. The DRW configuration contributes to improved braking stability.
Market Reception & Comparison
The RAM 3500 with the 6.7L Cummins HO engine consistently receives positive reviews for its towing capacity, durability, and overall performance. Critics praise the engine’s robust power delivery and the transmission’s smooth operation. Fuel economy, while not a primary concern for buyers in this segment, is generally considered competitive with other heavy-duty diesel trucks. Compared to Ford’s Super Duty and Chevrolet/GMC’s HD trucks, the RAM 3500 often stands out for its comfortable ride quality and refined interior. However, some critics note that the Cummins engine can be more expensive to maintain than gasoline alternatives.
Legacy
The Cummins 6.7-liter engine has earned a reputation for exceptional longevity and reliability. Properly maintained, these engines can easily exceed 300,000 miles. The DRW configuration, while adding complexity, is highly valued for its stability and towing capacity. On the used car market, RAM 3500s equipped with this powertrain command a premium price due to their proven performance and durability. These trucks remain a popular choice for commercial operators, farmers, and anyone needing a heavy-duty workhorse.
