Powertrain & Engine Architecture
The heart of this RAM 3500 is the 6.7-liter Cummins HO (High Output) turbodiesel engine, designated with engine code ETJ. This inline-six cylinder engine is a robust and well-regarded powerplant known for its durability and torque production. The “HO” designation indicates a higher horsepower rating compared to the standard 6.7L Cummins offered in the 2500/3500 series. The engine utilizes a diesel commonrail fuel injection system, delivering highly pressurized fuel directly into the cylinders for efficient combustion. The valvetrain employs an Overhead Valve (OHV) configuration, a design choice prioritizing simplicity and reliability. A turbocharger and intercooler work in tandem to increase air density entering the engine, boosting power output. The 2012 model year featured a six-speed manual transmission as standard, providing drivers with full control over gear selection. This transmission was chosen to handle the substantial torque output of the Cummins engine and provide optimal performance when towing or hauling heavy loads.
Driving Characteristics
The 3500 with the 6.7L HO Cummins and manual transmission delivers a driving experience focused on capability rather than outright speed. The engine produces a substantial 881 lb-ft of torque at a relatively low 1500 rpm, making it exceptionally adept at towing and hauling. The six-speed manual transmission allows for precise control of engine speed and torque delivery. While the 350 horsepower is adequate, the engine’s strength lies in its low-end grunt. Compared to higher-output Cummins variants, this version offers a more manageable power curve, making it easier to control when towing heavy loads. The manual transmission, while requiring more driver involvement, provides a more direct connection to the engine and allows for greater control in challenging conditions. The leaf spring rear suspension, while contributing to load-carrying capacity, can result in a firmer ride when unladen.
Equipment & Trim Levels
The 2012 RAM 3500 Crew Cab I 3500 6.7 HO Cummins TD (350 Hp) 4×4 DRW typically came standard with features geared towards work and utility. These included air conditioning, a basic audio system, vinyl upholstery, and a heavy-duty suspension. The Crew Cab configuration provided ample space for passengers, making it suitable for both work crews and families. Optional extras included upgraded audio systems, power windows and locks, heated mirrors, and various towing packages. Higher trim levels, such as the Laramie or Longhorn, offered more luxurious appointments, including leather upholstery, wood trim, and advanced infotainment systems. However, the base trims were often preferred by those prioritizing functionality and affordability.
Chassis & Braking
The RAM 3500 chassis is built around a robust frame designed to withstand the stresses of heavy-duty use. The front suspension utilizes an independent multi-link setup for improved ride quality and handling. The rear suspension employs a traditional leaf spring design, optimized for load-carrying capacity. Braking duties are handled by disc brakes on all four wheels, providing ample stopping power even when heavily loaded. An Anti-lock Braking System (ABS) is standard, enhancing safety and control during emergency braking situations. The Dual Rear Wheel (DRW) configuration provides increased stability and load-carrying capacity, making it ideal for demanding applications.
Market Reception & Comparison
The 2012 RAM 3500 with the 6.7L HO Cummins engine received generally positive reviews from automotive critics. It was praised for its robust powertrain, impressive towing capacity, and comfortable cabin. Compared to other heavy-duty trucks in its class, such as the Ford Super Duty and Chevrolet Silverado/GMC Sierra, the RAM 3500 offered a competitive combination of performance, features, and value. Fuel economy, while not a primary concern for heavy-duty truck buyers, was considered adequate for its class. Reliability was generally good, with the Cummins engine being particularly well-regarded for its longevity. The manual transmission was appreciated by those who preferred a more engaging driving experience, but some found it less convenient than the available automatic transmission.
Legacy
The 6.7L Cummins engine, in all its iterations, has earned a reputation for exceptional durability and longevity. The 2012 RAM 3500 with this engine continues to be a popular choice in the used truck market, particularly among those seeking a reliable and capable work truck. Properly maintained examples can accumulate hundreds of thousands of miles with minimal issues. The combination of a robust engine, a durable chassis, and a capable drivetrain makes this truck a valuable asset for those needing to tow and haul heavy loads. The 2012 model year represents a solid and dependable offering in the heavy-duty truck segment, and remains a viable option for buyers seeking a capable and long-lasting vehicle.
