2014-2017 RAM 1500 Regular Cab Long (DS facelift ) 3.0 EcoDiesel V6 (240 Hp) Automatic

Technical Specifications

The 2014-2017 RAM 1500 Regular Cab Long with the 3.0L EcoDiesel engine and automatic transmission was a key component of RAM’s strategy to offer a more fuel-efficient alternative in the full-size pickup market. The EcoDiesel engine, a collaboration between Chrysler (then part of Fiat Chrysler Automobiles) and VM Motori, was specifically designed to deliver diesel-like torque and fuel economy without the compromises often associated with larger diesel engines. This variant occupied a middle ground in the 1500 lineup, slotting below the more powerful 5.7L HEMI V8 models and above the base 3.6L Pentastar V6. The “DS” designation indicates the facelifted version of the fourth-generation 1500, which included styling updates and interior refinements.

Powertrain & Engine Architecture

The heart of this RAM 1500 is the EXF 3.0-liter EcoDiesel V6 engine. This engine utilizes a sophisticated diesel commonrail fuel injection system, delivering fuel at extremely high pressures for optimized combustion. The engine features a variable geometry turbocharger (VGT) and an intercooler to enhance power and efficiency. The VGT adjusts the turbine vanes to optimize airflow across a wide range of engine speeds, improving both low-end torque and high-end horsepower. The engine also employs a dual overhead camshaft (DOHC) valvetrain with four valves per cylinder, contributing to its efficient operation. The 8-speed automatic transmission, sourced from ZF, was a crucial component in maximizing the EcoDiesel’s potential. Its wide gear ratio spread allowed the engine to operate in its optimal power band more frequently, improving both acceleration and fuel economy. The transmission was designed for smooth shifting and durability, capable of handling the engine’s substantial torque output.

Driving Characteristics

The 240 horsepower and 419 lb-ft of torque produced by the 3.0L EcoDiesel, coupled with the 8-speed automatic, provided a noticeably different driving experience compared to the gasoline-powered 1500s. While not as quick off the line as the HEMI V8, the EcoDiesel offered strong low-end torque, making it well-suited for towing and hauling. The automatic transmission was programmed for smooth, comfortable shifts, prioritizing fuel efficiency over aggressive performance. The gear ratios were optimized to keep the engine within its peak torque range during typical driving conditions. Compared to the manual transmission versions of the EcoDiesel, the automatic offered greater convenience, especially in city driving. However, some drivers noted a slight reduction in fuel economy with the automatic due to the inherent losses in the torque converter.

Equipment & Trim Levels

The RAM 1500 Regular Cab Long (DS) 3.0 EcoDiesel Automatic typically came standard with features like air conditioning, power windows and locks, a basic audio system, and steel wheels. Higher trim levels, such as the SLT and Laramie, added features like alloy wheels, upgraded audio systems, cloth or leather upholstery, power-adjustable seats, and advanced safety features. Optional extras included a navigation system, a rearview camera, parking sensors, and various towing packages. The interior design was functional and durable, with a focus on providing a comfortable work environment. The Regular Cab configuration offered seating for two or three passengers, depending on the configuration.

Chassis & Braking

The RAM 1500’s chassis was designed to provide a comfortable ride and capable handling. The front suspension utilized a double wishbone design, while the rear suspension featured an independent multi-link setup. This combination helped to absorb bumps and provide a stable ride, even when the truck was loaded. Braking duties were handled by ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) was standard, enhancing safety during emergency braking situations. The steering was electric power-assisted, providing a light and responsive feel.

Market Reception & Comparison

The RAM 1500 EcoDiesel was generally well-received by critics and consumers alike. It was praised for its fuel efficiency, which was significantly better than that of the gasoline-powered 1500s, particularly during highway driving. However, some reviewers noted that the EcoDiesel engine was somewhat noisy compared to its gasoline counterparts. Compared to the 3.6L Pentastar V6, the EcoDiesel offered more torque and better towing capacity, but at a higher price point. Compared to the 5.7L HEMI V8, the EcoDiesel sacrificed some horsepower for improved fuel economy. Reliability was generally good, although some early EcoDiesel models experienced issues with the diesel particulate filter (DPF) and glow plug systems.

Legacy

The 3.0L EcoDiesel engine proved to be a popular option for RAM 1500 buyers seeking a fuel-efficient and capable pickup truck. While later iterations of the EcoDiesel engine faced emissions-related challenges, the 2014-2017 models generally hold up well in the used car market. The powertrain is known for its durability, and parts availability remains good. These trucks continue to be sought after by buyers who prioritize fuel economy and towing capacity. The EcoDiesel’s success helped to pave the way for the increased adoption of diesel engines in the light-duty pickup truck segment, demonstrating that diesel power could be both efficient and practical for everyday use.
