Powertrain & Engine Architecture
The heart of this RAM 2500 was the 6.7-liter Cummins inline-six diesel engine, designated as the ETJ code. This engine represented a significant evolution of Cummins’ diesel technology. It featured a common-rail fuel injection system, delivering highly pressurized fuel directly into the cylinders for improved combustion efficiency and reduced emissions. The turbocharger, coupled with an intercooler, forced more air into the engine, boosting power output. The engine’s robust construction, with a cast iron block and head, was renowned for its durability. The six-speed manual transmission provided drivers with full control over the engine’s power, allowing for precise gear selection for towing, hauling, or everyday driving.
Driving Characteristics
The 6.7L Cummins in this configuration delivered a substantial 827 Nm (609.96 lb-ft) of torque, making it a formidable workhorse. While the 350 horsepower output wasn’t the highest available in the RAM 2500/3500 lineup (higher output versions were offered), the torque curve was exceptionally broad and flat. This meant that ample pulling power was available from low engine speeds, making it ideal for towing heavy trailers or hauling large loads. The manual transmission, while requiring more driver involvement than an automatic, allowed for optimal control when navigating challenging terrain or managing heavy loads. Compared to the automatic transmission options, the manual offered a more direct connection to the engine and potentially slightly better fuel economy, though the difference wasn’t dramatic. The ride quality, while typical of a heavy-duty truck, was improved over previous generations thanks to refinements in the suspension system.
Equipment & Trim Levels
The 2500/3500 Crew Cab Long I with the 6.7L Cummins and manual transmission typically fell into the mid-range of available trim levels. Standard features generally included air conditioning, power windows and locks, a basic audio system, and vinyl upholstery. The Crew Cab configuration provided ample space for passengers, making it suitable for both work and family use. Optional extras included upgraded audio systems, leather upholstery, power-adjustable seats, a navigation system, and various towing packages. The Long Bed configuration offered increased cargo capacity, further enhancing the truck’s versatility.
Chassis & Braking
The RAM 2500/3500 featured a robust chassis designed to withstand the stresses of heavy-duty use. The front suspension utilized an independent multi-link setup, providing a more comfortable ride compared to traditional solid axles. The rear suspension employed leaf springs, which were well-suited for handling heavy loads. Braking duties were handled by 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.
Market Reception & Comparison
The RAM 2500/3500 with the 6.7L Cummins diesel engine was generally well-received by critics and consumers alike. It was praised for its powerful engine, robust construction, and comfortable ride. Compared to other heavy-duty trucks in its class, such as the Ford Super Duty and Chevrolet Silverado/GMC Sierra, the RAM offered a compelling combination of performance, features, and value. The manual transmission option appealed to drivers who preferred a more engaging driving experience and greater control over the engine’s power. Fuel economy, while not a primary concern for heavy-duty truck buyers, was respectable for a vehicle of this size and capability.
Legacy
The 6.7L Cummins engine has become legendary for its durability and longevity. Properly maintained, these engines are known to exceed 320,000 kilometers (200,000 miles) with relative ease. The 2010-2012 RAM 2500/3500 Crew Cab Long I with the 6.7L Cummins and manual transmission remains a popular choice in the used truck market today. Its combination of power, capability, and reliability makes it a valuable asset for anyone needing a heavy-duty pickup truck. While newer trucks offer more advanced technology and features, the simplicity and robustness of this generation continue to appeal to many buyers.
