Powertrain & Engine Architecture
The heart of this RAM 2500/3500 variant is the 6.7-liter Cummins inline-six diesel engine. This engine, designated with various codes depending on the specific year and emissions configuration, is a robust and well-regarded powerplant known for its durability and torque output. The 370 horsepower version typically utilizes a variable geometry turbocharger (VGT) and a high-pressure common rail fuel injection system. The common rail system allows for precise fuel delivery, optimizing combustion efficiency and reducing emissions. The engine features four valves per cylinder, enhancing breathing and contributing to its power output. The automatic transmission paired with this engine is typically a heavy-duty six-speed unit, designed to handle the substantial torque produced by the Cummins diesel. This transmission is electronically controlled, offering smooth shifts and optimized gear selection for towing and hauling.
Driving Characteristics
The 370 hp/1084 lb-ft configuration of the RAM 2500/3500 delivers a distinctly different driving experience compared to the higher-output Cummins variants or gasoline-powered models. While not offering the outright acceleration of its more powerful siblings, this setup excels in providing a broad, usable torque curve. This translates to effortless towing and hauling, even with substantial loads. The automatic transmission is tuned for smooth, predictable shifts, prioritizing stability and control over sporty responsiveness. The gear ratios are optimized for maximizing torque at lower engine speeds, making it ideal for demanding work applications. Compared to a manual transmission equipped model, the automatic offers convenience, especially in stop-and-go traffic or when navigating challenging terrain while towing.
Equipment & Trim Levels
The 2500/3500 Regular Cab with the 6.7L Cummins and automatic transmission typically served as a base or mid-range offering. Standard equipment generally included air conditioning, a basic infotainment system with a touchscreen display, vinyl or cloth upholstery, and a heavy-duty suspension. Optional extras could include upgraded infotainment systems with navigation, leather upholstery, power-adjustable seats, a premium sound system, and various towing packages. The Regular Cab configuration itself is a no-frills option, prioritizing functionality and affordability over passenger comfort. It typically features a bench seat and minimal interior appointments.
Chassis & Braking
The RAM 2500/3500 chassis is built around a robust fully boxed frame, designed to withstand the stresses of heavy-duty use. The suspension system utilizes a multi-link configuration at both the front and rear, providing a comfortable ride quality even when unladen. Braking duties are handled by disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard, enhancing safety and control during emergency braking situations. The rear axle ratios varied depending on the specific configuration and intended use, with options available to optimize either fuel economy or towing capacity.
Market Reception & Comparison
Critics generally praised the 6.7L Cummins-powered RAM 2500/3500 for its impressive towing and hauling capabilities, as well as its comfortable ride quality. The 370 hp version was often seen as a sweet spot for buyers who needed heavy-duty capability but didn’t require the highest possible power output. Fuel economy, while not a strong point for any heavy-duty truck, was considered reasonable for its class. Compared to the higher-output Cummins variants, this configuration offered a lower price point and potentially lower maintenance costs. Compared to gasoline-powered options, the Cummins diesel provided significantly more torque and better fuel economy when towing heavy loads.
Legacy
The 6.7L Cummins engine has earned a reputation for exceptional durability and longevity. These engines, when properly maintained, are known to exceed 200,000 or even 300,000 miles without major issues. On the used car market, RAM 2500/3500 models equipped with this powertrain hold their value relatively well, particularly those that have been well-maintained and have a documented service history. The combination of a robust engine, a capable chassis, and a comfortable interior has made this configuration a popular choice among truck buyers for years, and continues to be a sought-after option in the used truck market today.
