Powertrain & Engine Architecture
The heart of this RAM 3500 variant is the 6.7-liter Cummins turbodiesel engine, specifically the High Output (HO) version. The Cummins ETK engine is an inline-six cylinder design, renowned for its durability and torque output. The HO designation indicates a higher horsepower rating achieved through revised turbocharger tuning and fuel injection calibration. The engine utilizes a diesel commonrail fuel injection system, delivering highly pressurized fuel directly into the cylinders for efficient combustion. The overhead valve (OHV) valvetrain, while a more traditional design, contributes to the engine’s robustness and low-end torque characteristics. The turbocharger and intercooler work in tandem to increase air density, further enhancing power and efficiency. Paired with this engine is a six-speed automatic transmission manufactured by Aisin, known for its smooth shifting and ability to handle the engine’s substantial torque. This transmission was a significant upgrade over earlier offerings, providing improved drivability and efficiency.
Driving Characteristics
The 385 horsepower and 1152 lb-ft of torque delivered by this powertrain combination resulted in impressive performance, even when fully loaded or towing. While not as quick as lighter-duty trucks, the RAM 3500 offered effortless acceleration and strong pulling power. The Aisin transmission’s gear ratios were well-matched to the engine’s torque curve, providing ample power in most driving situations. Compared to the standard output Cummins engine, the HO version offered a noticeable increase in horsepower, making it more suitable for demanding tasks. Compared to gasoline-powered RAM 2500/3500 models, the diesel offered significantly more torque at lower RPMs, making it ideal for towing heavy loads. The automatic transmission, while convenient, did result in a slight reduction in fuel economy compared to the available manual transmission options.
Equipment & Trim Levels
The 3500 HO Cummins 4×4 Automatic was typically offered in higher trim levels, such as Laramie, Longhorn, and Limited. Standard features included air conditioning, power windows and locks, a premium audio system, and a tilt-adjustable steering wheel. Higher trims added features like leather upholstery, heated and ventilated seats, a navigation system, and a rear-seat entertainment system. Optional extras included a sunroof, upgraded wheels, and various towing packages. The Crew Cab configuration provided ample space for passengers, making it a comfortable choice for both work and family use.
Chassis & Braking
The RAM 3500 featured a robust chassis designed to handle heavy loads. The front suspension utilized an independent multi-link design for improved ride quality and handling, while the rear suspension employed a traditional leaf spring setup for durability 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. The 4×4 system offered various modes, including 2WD, 4WD High, and 4WD Low, allowing drivers to adapt to different terrain conditions.
Market Reception & Comparison
The RAM 3500 with the 6.7 HO Cummins engine received generally positive reviews from critics. It was praised for its powerful engine, comfortable ride, and spacious interior. Fuel economy, while not exceptional, was considered reasonable for a heavy-duty truck. Compared to competitors like the Ford Super Duty and Chevrolet Silverado/GMC Sierra, the RAM 3500 was often lauded for its refined interior and comfortable ride. Reliability was generally good, although some owners reported issues with the exhaust gas recirculation (EGR) system and diesel particulate filter (DPF).
Legacy
The 6.7-liter Cummins engine has become legendary for its durability and longevity. The 2013-2018 RAM 3500 equipped with this engine continues to be a popular choice in the used truck market. Well-maintained examples can command high prices due to their reputation for reliability and capability. The Aisin transmission has also proven to be exceptionally durable, contributing to the overall longevity of these trucks. While modern trucks offer more advanced technology and features, the 2013-2018 RAM 3500 remains a capable and reliable workhorse for those needing a heavy-duty pickup.
