Powertrain & Engine Architecture
The heart of this RAM 2500 is the 6.7-liter Cummins inline-six diesel engine, designated with the ETJ code. This engine is a robust, over-head valve (OHV) design known for its durability and low-end torque. The 350 horsepower output was achieved through a turbocharger and intercooler setup, optimizing air intake for increased combustion efficiency. The engine utilizes a diesel common rail fuel injection system, delivering highly pressurized fuel directly into the cylinders for precise control over the combustion process. The 6.7L Cummins is renowned for its ability to withstand high mileage and demanding work conditions. The manual transmission offered with this engine is a six-speed unit, designed to handle the substantial torque output and provide a direct driving experience.
Driving Characteristics
The 6.7L Cummins with 350 hp and a manual transmission in the RAM 2500 offered a compelling blend of power and usability. While not the fastest configuration available (the higher-output Cummins variants provided significantly more horsepower), this setup excelled in situations requiring substantial pulling power. The engine’s peak torque of 881 Nm (649.79 lb-ft) was readily available at low RPMs, making it ideal for towing heavy loads or navigating challenging terrain. The six-speed manual transmission allowed for precise gear selection and control, enhancing the driver’s ability to manage power delivery. Compared to automatic transmission equipped models, the manual offered a more engaging driving experience and potentially slightly improved fuel economy, though at the cost of some convenience.
Equipment & Trim Levels
The 2500 Regular Cab with the 6.7L Cummins typically fell into the mid-range of the RAM heavy-duty lineup. Standard features generally included air conditioning, a basic audio system, vinyl upholstery, and manually adjustable seats. Higher trim levels, such as the SLT or Laramie, added features like cloth or leather upholstery, power windows and locks, upgraded audio systems, and chrome exterior accents. Optional extras included a trailer brake controller, a limited-slip differential, and various towing packages. The Regular Cab configuration prioritized functionality and affordability, offering a no-frills interior focused on work-oriented needs.
Chassis & Braking
The RAM 2500 featured a robust chassis designed to withstand heavy loads. The front suspension utilized a double wishbone setup, while the rear suspension employed leaf springs, a traditional design favored for its load-carrying capacity. Brakes were disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) was standard, enhancing safety and control during emergency braking situations. The truck’s heavy-duty construction and well-engineered suspension system contributed to its stability and ride quality, even when fully loaded.
Market Reception & Comparison
The RAM 2500/3500 with the 6.7L Cummins diesel engine consistently received positive reviews for its towing capacity, durability, and overall value. Critics praised the engine’s robust construction and impressive torque output. Compared to the gasoline-powered RAM 2500 models, the Cummins diesel offered significantly better fuel economy when towing heavy loads. However, the diesel engine carried a higher initial cost. Compared to the higher-output Cummins variants, the 350 hp version offered a more balanced combination of power, fuel economy, and affordability, making it a popular choice for buyers who didn’t require the absolute maximum towing capacity.
Legacy
The 6.7L Cummins engine in the 2013-2018 RAM 2500/3500 has proven to be exceptionally reliable, with many examples exceeding 320,000 kilometers (200,000 miles) with proper maintenance. These trucks remain highly sought after in the used car market, particularly among buyers who need a capable and dependable work truck. The combination of a robust engine, durable chassis, and readily available parts ensures that these RAM 2500s will continue to provide years of service. The 6.7L Cummins engine has cemented its reputation as one of the most reliable and long-lasting diesel engines ever produced, contributing significantly to the RAM brand’s strong standing in the heavy-duty truck segment.
