The RAM 1500 Regular Cab Long (DS) with the 3.6 Pentastar V6 engine and automatic transmission, produced from 2013 to 2018, represents a significant iteration of the full-size pickup truck offered by Stellantis (then Chrysler Group LLC) in the North American market. This variant, part of the DS facelift generation, occupied a crucial position in the 1500 lineup, offering a balance between capability, affordability, and fuel efficiency. It catered to buyers needing a workhorse truck without the premium price tag of higher trim levels or the increased running costs associated with larger engines. The “Long” designation refers to the extended cab configuration, providing additional interior space compared to the standard cab models. This particular configuration was a mainstay for fleet and individual buyers prioritizing practicality and value.

Introduction
The 2013-2018 RAM 1500 Regular Cab Long DS, powered by the 3.6-liter Pentastar V6 and paired with an eight-speed automatic transmission, was a key offering in the redesigned fourth-generation RAM 1500 series. This generation, internally designated DS after the facelift, brought significant improvements in ride quality, interior refinement, and technology compared to its predecessor. The Regular Cab Long configuration specifically targeted buyers who needed a practical, affordable, and capable pickup for work or personal use, prioritizing bed length and interior space over the added convenience of a crew cab. This variant served as the entry point into the 1500 range for many customers, offering a compelling value proposition.
Powertrain & Engine Architecture
The heart of this RAM 1500 is the 3.6-liter Pentastar V6 engine, bearing the code ERB. This engine is a modern, naturally aspirated powerplant featuring a 60-degree V-angle. It utilizes multi-port fuel injection and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. The Pentastar engine is known for its smooth operation and relatively good fuel economy for a V6 of this displacement. The eight-speed automatic transmission (8HP70) is a crucial component, providing a wide gear ratio spread for optimized acceleration and highway cruising. This transmission, sourced from ZF, contributed significantly to the improved fuel efficiency and refined driving experience of the DS generation RAM 1500. The engine’s design prioritizes low-end torque, making it suitable for hauling and towing, while still delivering respectable horsepower at higher RPMs.
Driving Characteristics
The 305-horsepower, V6-powered RAM 1500 Regular Cab Long offered a competent, if not exhilarating, driving experience. While it lacked the outright acceleration of the available 5.7-liter HEMI V8, the V6 provided sufficient power for everyday tasks and moderate towing duties. The eight-speed automatic transmission played a vital role in keeping the engine in its optimal power band. Gear changes were generally smooth and responsive. Compared to manual transmission equipped models, the automatic offered greater convenience, particularly in stop-and-go traffic. However, it did result in a slight reduction in fuel economy. The truck’s suspension, tuned for a balance between ride comfort and load-carrying capability, provided a reasonably smooth ride even when unladen. The rear-wheel-drive configuration offered a traditional truck feel, while available four-wheel-drive systems enhanced traction in inclement weather or off-road conditions.
Equipment & Trim Levels
The RAM 1500 Regular Cab Long with the 3.6L V6 typically came standard with features such as air conditioning, a basic audio system, vinyl upholstery, and steel wheels. Higher trim levels, such as the SLT, offered upgrades like cloth upholstery, power windows and locks, keyless entry, and an upgraded audio system. Optional extras included a navigation system, a rearview camera, and various towing packages. The interior design, while functional, was relatively basic compared to higher-end trims. The focus was on durability and practicality rather than luxury. The Long bed provided ample cargo space, making it ideal for hauling building materials, landscaping supplies, or other large items.
Chassis & Braking
The RAM 1500 Regular Cab Long utilized a body-on-frame construction, providing a robust and durable platform. The front suspension featured a double wishbone design, while the rear suspension employed an independent multi-link setup. This configuration aimed to deliver a comfortable ride and good handling characteristics. Braking duties were handled by ventilated discs at the front and solid discs at the rear. Anti-lock braking system (ABS) was standard. The truck’s steering was power-assisted, providing relatively light and easy steering effort. The chassis was designed to accommodate a variety of payloads and towing configurations, with appropriate suspension tuning and brake upgrades available as options.
Market Reception & Comparison
The 3.6L V6-powered RAM 1500 Regular Cab Long was generally well-received by critics and consumers alike. It was praised for its fuel efficiency, smooth ride, and competitive pricing. Compared to the V8-powered models, the V6 offered a lower entry price and better gas mileage, making it an attractive option for budget-conscious buyers. However, some reviewers noted that the V6 lacked the power and towing capacity of the V8. Compared to competitors like the Ford F-150 and Chevrolet Silverado, the RAM 1500 offered a unique combination of features and value. The RAM’s focus on ride comfort and interior refinement set it apart from some of its rivals.
Legacy
The 3.6L Pentastar V6 engine has proven to be a reliable and durable powerplant, and the eight-speed automatic transmission has also demonstrated good long-term reliability. In the used car market, the 2013-2018 RAM 1500 Regular Cab Long with the V6 engine represents a solid value proposition. These trucks are generally affordable to purchase and maintain, and they offer a good balance of capability and fuel efficiency. While they may not be as desirable as the V8-powered models, they remain a popular choice for buyers who need a practical and dependable pickup truck.
