Introduction
The 2013-2018 RAM 1500 Regular Cab with the 3.6-liter Pentastar V6 and 4×4 automatic transmission was a mainstay of the RAM truck lineup. Positioned as an entry-level or mid-range offering, it provided a more accessible price point compared to the larger V8-powered models, while still delivering respectable performance and the capability expected of a full-size pickup. This model was built on the DS platform, a refreshed version of the previous generation, incorporating improvements to ride quality, interior refinement, and available technology. The Regular Cab configuration, with its two or three-passenger seating, catered to buyers prioritizing functionality and work-oriented needs over passenger space.
Powertrain & Engine Architecture
At the heart of this RAM 1500 variant lies the 3.6-liter Pentastar V6 engine, designated as the ERB code. This engine is a modern, naturally aspirated powerplant featuring a 60-degree V-angle. It utilizes a multi-port fuel injection system, delivering fuel directly to the intake ports, and a double overhead camshaft (DOHC) valvetrain with four valves per cylinder. This configuration optimizes airflow and combustion efficiency. The engine produces 305 horsepower at 6400 rpm and 268 lb-ft of torque at 4175 rpm. Paired with this engine is an eight-speed automatic transmission, a significant upgrade from the previous four- or five-speed automatics. This transmission provides a wider gear ratio spread, improving both fuel economy and acceleration. The 4×4 system employs an electronically controlled transfer case, allowing the driver to seamlessly switch between two-wheel drive and four-wheel drive modes, enhancing traction in various conditions.
Driving Characteristics
The 3.6L V6 and eight-speed automatic combination in the RAM 1500 Regular Cab delivers a noticeably different driving experience compared to the available 5.7L HEMI V8. While the V6 lacks the raw power and immediate response of the V8, it provides adequate performance for everyday driving and moderate towing needs. The eight-speed transmission helps to keep the engine in its optimal power band, mitigating some of the power deficit. Gear changes are smooth and generally unnoticeable. The 4×4 system provides enhanced stability and traction, particularly on slippery surfaces. However, the Regular Cab’s relatively light weight (around 4,720 lbs) helps to offset the V6’s lower output, resulting in a respectable power-to-weight ratio. Compared to manual transmission equipped models, the automatic offers convenience and ease of use, but at the expense of some driver control and fuel efficiency.
Equipment & Trim Levels
The RAM 1500 Regular Cab with the 3.6L V6 4×4 was typically offered in base trims like STX and Tradesman. Standard features generally included air conditioning, a basic audio system with an auxiliary input, vinyl upholstery, and steel wheels. Higher trims, such as the SLT, added features like cloth upholstery, power windows and locks, keyless entry, and an upgraded audio system. Optional extras included a navigation system, a rearview camera, a trailer brake controller, and various appearance packages. The interior design was functional and durable, prioritizing practicality over luxury. The dashboard layout was straightforward, with easy-to-reach controls.
Chassis & Braking
The RAM 1500 Regular Cab utilizes a body-on-frame construction, providing a robust and durable platform. The front suspension consists of a double wishbone setup, while the rear suspension employs an independent multi-link design. This combination delivers a comfortable ride quality, even when the truck is unloaded. Braking duties are handled by ventilated discs at the front and solid discs at the rear. Anti-lock brakes (ABS) are standard, enhancing safety and control during emergency braking situations. The steering system is electric power steering, providing a responsive and precise feel.
Market Reception & Comparison
The 3.6L V6-powered RAM 1500 Regular Cab was generally well-received by critics as a capable and fuel-efficient option in the full-size pickup segment. While it didn’t offer the same level of performance as the V8 models, it provided a compelling value proposition for buyers who didn’t require heavy-duty towing or hauling capabilities. Fuel economy was a key selling point, with EPA estimates ranging around 17 mpg city and 23 mpg highway. Compared to competitors like the Ford F-150 and Chevrolet Silverado with their base V6 engines, the RAM 1500 offered a more refined driving experience and a more powerful engine. However, some critics noted that the interior materials were not as upscale as those found in some competing models.
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 longevity. In the used car market, the 2013-2018 RAM 1500 Regular Cab with this powertrain configuration remains a popular choice for buyers seeking an affordable and capable pickup truck. Maintenance costs are generally reasonable, and parts availability is good. However, as with any used vehicle, it’s important to have a pre-purchase inspection performed to identify any potential issues. This variant represents a sweet spot in the RAM 1500 lineup, offering a balance of performance, efficiency, and value that continues to appeal to a wide range of buyers.
