Powertrain & Engine Architecture
The heart of this RAM 2500/3500 variant is the 6.7-liter Cummins inline-six turbodiesel engine, designated with the ETJ code. This engine represents a significant evolution of Cummins’ long-standing reputation for durable and powerful diesel engines. The 6.7L Cummins utilizes a common-rail direct fuel injection system, delivering fuel at extremely high pressures for optimized combustion and reduced emissions. The engine is equipped with a variable geometry turbocharger (VGT) and an intercooler, enhancing both power and efficiency. The engine’s valvetrain features four valves per cylinder, contributing to improved breathing and overall performance. The automatic transmission paired with this engine is a heavy-duty six-speed unit, designed to handle the substantial torque output of the Cummins diesel. This transmission features electronic control for smooth and precise shifting, and is built for durability in demanding applications.
Driving Characteristics
The 350 horsepower and 881 lb-ft of torque delivered by this powertrain configuration provides substantial pulling power and a robust driving experience. While not as quick accelerating as higher-output Cummins variants, the 350 hp version offers a more relaxed and manageable driving experience, particularly for those prioritizing towing and hauling over outright speed. The automatic transmission, while providing convenience, does result in some power loss compared to a manual transmission. The gear ratios are optimized for towing, with lower gears providing ample torque for starting heavy loads and climbing hills. In real-world conditions, this truck excels at tasks like hauling trailers, transporting heavy equipment, and navigating challenging terrain.
Equipment & Trim Levels
The 2500/3500 Regular Cab I with the 6.7L Cummins and automatic transmission typically came standard with features geared towards work and utility. These included a heavy-duty vinyl interior, air conditioning, and a basic audio system. Higher trim levels, such as the SLT and Laramie, offered upgrades like cloth or leather upholstery, power windows and locks, premium audio systems, and chrome exterior trim. Optional extras included a trailer brake controller, a limited-slip differential, and various towing packages. The Regular Cab configuration itself was the most basic body style, prioritizing functionality and affordability over passenger comfort.
Chassis & Braking
The chassis of the RAM 2500/3500 is a robust body-on-frame construction, designed to withstand the stresses of heavy-duty use. The front suspension utilizes a double wishbone setup, providing a comfortable ride and good handling characteristics. The rear suspension employs leaf springs, which are well-suited for supporting heavy loads. Braking duties are handled by ventilated discs at the front and discs at the rear, providing ample stopping power. An Anti-lock Braking System (ABS) is standard, enhancing safety and control during emergency braking situations. The truck’s track width is wider than some competitors, contributing to improved stability.
Market Reception & Comparison
The RAM 2500/3500 with the 6.7L Cummins and automatic transmission was generally well-received by critics and consumers alike. It was praised for its powerful engine, robust construction, and impressive towing capacity. Compared to the higher-output Cummins variants (370 hp and 400 hp), this 350 hp version offered a more affordable entry point into the heavy-duty truck market. It also provided a better balance between power and fuel economy. Compared to gasoline-powered alternatives, the Cummins diesel offered significantly better fuel economy and longer engine life. However, the diesel engine did come with a higher initial cost and potentially higher maintenance expenses.
Legacy
The 6.7-liter Cummins engine has proven to be exceptionally durable and reliable over the long term. Properly maintained examples of this powertrain can easily exceed 200,000 miles, and many continue to operate reliably well beyond that mark. In the used car market, these trucks hold their value relatively well, particularly those in good condition with well-documented maintenance histories. The combination of a powerful diesel engine, a robust chassis, and a capable automatic transmission makes the RAM 2500/3500 Regular Cab I with the 6.7L Cummins a popular choice for buyers seeking a dependable and capable heavy-duty pickup truck.
