Powertrain & Engine Architecture
The heart of this RAM 3500 is the 6.7-liter Cummins ETK inline-six diesel engine. This engine is a robust, over-head valve (OHV) design known for its durability and torque output. The “HO” designation signifies a higher output version compared to the standard 6.7L Cummins offered in the 2500/3500 range. It utilizes a turbocharger and intercooler to boost power and efficiency. The fuel system is a common-rail direct injection system, delivering highly pressurized fuel directly into the cylinders for optimized combustion. This engine produces 385 horsepower at 2800 rpm and a substantial 1152 Nm (849.67 lb-ft) of torque at 1700 rpm. The engine’s large displacement and robust construction contribute to its longevity and ability to handle heavy loads. The Aisin six-speed automatic transmission is a key component, chosen for its durability and ability to handle the engine’s high torque output. It features electronically controlled shifting and is designed to provide smooth and reliable operation under demanding conditions.
Driving Characteristics
The 385 hp/1152 Nm combination delivers a strong and confident driving experience. While not as overtly powerful as the higher-output Cummins variants, this configuration provides ample power for towing and hauling, making it suitable for a wide range of work applications. The Aisin transmission is well-matched to the engine, providing smooth shifts and a usable gear ratio spread. Compared to manual transmission equipped models, the automatic offers convenience, especially in stop-and-go traffic or when navigating challenging terrain. However, some drivers may prefer the more direct control offered by a manual gearbox. The 4×4 system provides excellent traction in various conditions, making it capable off-road. The leaf spring rear suspension, while contributing to load-carrying capacity, can result in a firmer ride when unladen compared to coil-spring setups.
Equipment & Trim Levels
The RAM 2500/3500 Regular Cab I (facelift 2013) with this powertrain was typically offered in work-oriented trim levels, such as ST or SLT. Standard features generally included air conditioning, a basic audio system, vinyl upholstery, and manually adjustable seats. Optional extras could include power windows and locks, upgraded audio systems, cruise control, and various towing packages. The interior was functional and durable, designed to withstand the rigors of daily use. The Regular Cab configuration offered seating for two or three occupants, prioritizing practicality over passenger comfort.
Chassis & Braking
The chassis of the RAM 2500/3500 is a body-on-frame construction, providing a robust foundation for heavy-duty applications. The front suspension utilizes an independent multi-link setup for improved ride quality and handling. The rear suspension employs leaf springs, which are well-suited for supporting heavy loads. Braking duties are handled by disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard, enhancing safety and control during emergency braking situations. The heavy-duty chassis and braking system are designed to handle the truck’s substantial weight and towing capacity.
Market Reception & Comparison
The 385 hp Cummins-powered RAM 3500 was generally well-received by critics and consumers alike. It was praised for its strong towing capacity, reliable powertrain, and comfortable ride (for a heavy-duty truck). Compared to the lower-powered gasoline engine options, the Cummins diesel offered significantly more torque and fuel efficiency, making it a popular choice for those who frequently tow or haul heavy loads. Compared to the higher-output Cummins variants, this configuration offered a more affordable price point and slightly better fuel economy. However, some reviewers noted that it lacked the outright power of the more expensive models.
Legacy
The 6.7L Cummins engine, in all its iterations, has earned a reputation for exceptional durability and longevity. This particular 385 hp version is no exception. Properly maintained, these engines can easily exceed 200,000 miles (320,000 km) of reliable service. In the used car market, these trucks remain popular due to their proven track record and strong resale value. They are often sought after by those needing a capable and dependable work truck. While newer RAM models offer more advanced technology and features, the 2013-2018 3500 with the 6.7 HO Cummins remains a solid and capable choice for those seeking a robust and reliable heavy-duty pickup.
