Powertrain & Engine Architecture
The heart of this RAM 2500 variant is the 6.7-liter Cummins inline-six diesel engine, designated with the ETJ code. This engine represented a significant leap forward for Cummins, incorporating advanced technologies for improved performance and reduced emissions. The engine utilizes a high-pressure common rail fuel injection system, delivering fuel directly into the cylinders at extremely high pressures for optimal combustion. A variable geometry turbocharger (VGT) with an intercooler further enhances power output and responsiveness. The engine’s robust construction, featuring a cast iron block and head, is renowned for its durability and longevity. While a six-speed manual transmission was standard, an optional six-speed automatic transmission was available, though less common in this configuration. The automatic transmission was designed to handle the substantial torque output of the Cummins engine, providing smooth and reliable shifting.
Driving Characteristics
The 350 horsepower and 827 lb-ft of torque delivered by the 6.7L Cummins in the 2500 provided substantial pulling power. While not as quick as the gasoline-powered variants, the diesel offered a significantly flatter torque curve, making it ideal for towing and hauling heavy loads. The manual transmission, while requiring more driver involvement, allowed for precise control and maximized power delivery. The automatic transmission, while offering convenience, could feel slightly less responsive, particularly when downshifting. The truck’s substantial weight and long wheelbase contributed to a comfortable ride, even when unladen, but also resulted in noticeable body roll during cornering. Overall, the driving experience was geared towards functionality and capability rather than sporty handling.
Equipment & Trim Levels
The 2500/3500 Crew Cab Long I with the Cummins diesel typically came standard with features like air conditioning, power windows and locks, a basic audio system, and vinyl upholstery. The Crew Cab configuration offered generous passenger space, making it suitable for families or work crews. Higher trim levels, such as the Laramie and Longhorn, added luxury features like leather upholstery, premium audio systems, heated and ventilated seats, and woodgrain interior trim. Optional extras included a navigation system, a sunroof, and various towing packages. The specific equipment level varied depending on the buyer’s preferences and budget.
Chassis & Braking
The RAM 2500/3500 featured a robust chassis designed to withstand the stresses of heavy-duty use. The front suspension utilized a double wishbone setup, while the rear suspension employed leaf springs. This combination provided a good balance between ride comfort and load-carrying capacity. Disc brakes were standard on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) was also standard, enhancing safety and control during emergency braking situations. The truck’s heavy weight and long wheelbase contributed to its stability, but also required a larger turning radius.
Market Reception & Comparison
The 2500/3500 with the 6.7L Cummins diesel was generally well-received by critics and buyers alike. It was praised for its powerful engine, comfortable ride, and spacious interior. Compared to the gasoline-powered variants, the diesel offered superior fuel economy and towing capacity, making it a popular choice for those who needed a workhorse truck. However, the diesel engine also carried a higher price tag and required more frequent maintenance. Compared to competing trucks from Ford and General Motors, the RAM 2500/3500 was often seen as offering a more refined interior and a more comfortable ride.
Legacy
The 6.7-liter Cummins diesel engine has become legendary for its reliability and longevity. Properly maintained, these engines can easily exceed 200,000 miles, and many are still in service today. The 2010-2012 RAM 2500/3500 Crew Cab Long I with this engine remains a popular choice in the used truck market, commanding relatively high prices due to its reputation for durability and capability. While newer trucks offer more advanced features and technologies, this generation represents a sweet spot for those seeking a robust and reliable heavy-duty truck at a reasonable price. The engine’s continued popularity has cemented its place as a benchmark in the diesel truck segment.
