INTRODUCTION

The 2025 RAM 3500 with the 6.4-liter HEMI V8 and 4×4 drivetrain is a heavy-duty pickup truck designed for demanding tasks. Built on the DT platform, which debuted in 2019 and received a facelift for 2025, this variant caters to customers who require substantial towing and hauling capabilities without opting for the higher cost and complexity of a diesel engine. It slots into the lineup as a powerful, gasoline-powered alternative, offering a balance of performance, capability, and relative affordability. The Regular Cab configuration emphasizes practicality and work-focused functionality, making it a popular choice for commercial users and those prioritizing interior space over passenger comfort.

Powertrain & Engine Architecture

At the heart of this RAM 3500 is the 6.4-liter (391.59 cubic inches) HEMI V8 engine, internally designated as part of the Generation III HEMI family. This engine features a cast iron block, aluminum cylinder heads, and a robust crankshaft designed for high torque output. The engine utilizes a multi-port fuel injection system, delivering fuel directly to each cylinder for efficient combustion. The valvetrain employs an overhead valve (OHV) configuration with Variable Cam Timing (VCT) on the intake valves, optimizing performance across the engine’s operating range. The 6.4L HEMI produces 405 horsepower at 5600 rpm and 429 lb-ft of torque at 4000 rpm.

The engine is mated to the TorqueFlite 8-speed automatic transmission, a proven unit known for its durability and smooth shifting characteristics. This transmission is specifically tuned to handle the high torque output of the HEMI V8 and provides a wide range of gear ratios for optimal performance in various driving conditions. The 4×4 drivetrain features an electronically controlled transfer case, allowing the driver to seamlessly switch between two-wheel drive and four-wheel drive modes, including a low-range setting for enhanced off-road capability and heavy towing.

Driving Characteristics

The 2025 RAM 3500 6.4L HEMI exhibits strong acceleration and ample power for everyday driving and demanding tasks. While not as fuel-efficient as smaller engines, the HEMI V8 delivers a satisfying level of performance, particularly when towing or hauling heavy loads. The 8-speed automatic transmission contributes to a smooth and responsive driving experience, with well-spaced gear ratios that keep the engine in its optimal power band. Compared to the diesel-powered RAM 3500 models, the 6.4L HEMI offers quicker throttle response and a more traditional V8 sound. However, it lacks the diesel’s superior low-end torque and fuel economy. Compared to the base V6 engine, the 6.4L HEMI provides a significant performance upgrade, making it a more suitable choice for those who frequently tow or haul heavy loads.

Equipment & Trim Levels

The Regular Cab configuration of the RAM 3500 typically focuses on functionality and durability. Standard features generally include air conditioning, a basic infotainment system with a touchscreen display, and vinyl upholstery. Higher trim levels, such as the Tradesman, Big Horn/Laramie, and Limited, add features like cloth or leather upholstery, upgraded infotainment systems with larger screens, premium sound systems, and various convenience features. Optional extras include a navigation system, parking sensors, a rearview camera, and advanced safety features like blind-spot monitoring and rear cross-traffic alert.

Chassis & Braking

The RAM 3500 features a heavy-duty chassis designed to withstand the stresses of demanding work. The front suspension utilizes a coil spring and rigid axle configuration with a transverse stabilizer bar, providing a comfortable ride and stable handling. The rear suspension employs a leaf spring setup, offering robust load-carrying capacity. Air suspension is available as an option, providing adjustable ride height and improved ride comfort. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power even when towing heavy loads. An Anti-lock Braking System (ABS) is standard, enhancing safety and control during emergency braking situations.

Market Reception & Comparison

The RAM 3500 6.4L HEMI has generally received positive reviews from critics, who praise its powerful engine, smooth transmission, and capable 4×4 drivetrain. It’s often seen as a compelling alternative to diesel-powered trucks for buyers who don’t require the ultimate towing capacity or fuel economy. Compared to the Cummins diesel engine, the 6.4L HEMI offers a lower initial cost and simpler maintenance requirements. However, the diesel engine provides significantly more torque and better fuel economy, making it a more suitable choice for heavy-duty applications. Fuel economy for the 6.4L HEMI is typically in the range of 14-17 mpg combined.

Legacy

The 6.4-liter HEMI V8 has proven to be a reliable and durable engine in the RAM 3500. While not as widely celebrated as the Cummins diesel, it has earned a reputation for its robust construction and relatively straightforward maintenance. In the used car market, RAM 3500 models equipped with the 6.4L HEMI V8 generally hold their value well, particularly those in good condition with well-documented maintenance records. The combination of power, capability, and relative affordability makes this variant a popular choice among truck buyers seeking a heavy-duty pickup that can handle a wide range of tasks.
