INTRODUCTION
The 2025 Ram 3500 with the 6.4-liter HEMI V8 and TorqueFlite automatic transmission is a heavy-duty pickup truck designed for demanding tasks. It slots into the Ram HD lineup as a step up from the base engine options, offering significantly more power and towing capacity than the smaller displacement engines. The “Regular Cab II” designation refers to the body style – a two-door configuration primarily aimed at commercial users or those prioritizing functionality over passenger space. The facelift for 2025 brought cosmetic updates to the exterior and interior, along with enhancements to available technology features, but the core powertrain remained largely unchanged.
Powertrain & Engine Architecture
At the heart of this variant lies the 6.4-liter (391.59 cubic inches) HEMI V8 engine, internally designated as part of the Chrysler 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. The valvetrain employs an overhead valve (OHV) configuration with variable valve timing (VCT) on the intake camshaft, optimizing performance and efficiency across the rev 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. This transmission is specifically tuned for heavy-duty applications, with reinforced components and optimized gear ratios to handle the engine’s substantial torque output. The TorqueFlite transmission features electronic shift control and offers selectable drive modes, including Tow/Haul mode, which adjusts shift points for optimal towing performance. Cylinder deactivation (MDS) is also included, shutting down four cylinders during light-load cruising to improve fuel economy.
Driving Characteristics
The 6.4-liter HEMI V8 provides ample power for everyday driving and demanding tasks. While not as fuel-efficient as the diesel options, it delivers a responsive and engaging driving experience. The 8-speed automatic transmission helps to keep the engine in its optimal power band, providing smooth acceleration and confident passing power. Compared to the base V6 engine, the 6.4L offers a significant performance upgrade, particularly when towing or hauling heavy loads. Compared to the Cummins diesel engines offered in the Ram 3500, the HEMI provides quicker acceleration at lower speeds but lacks the diesel’s superior low-end torque and fuel economy. The gear ratios in the TorqueFlite transmission are optimized for both on-road comfort and off-road capability, providing a balance between power and efficiency.
Equipment & Trim Levels
The 2500/3500 Regular Cab with the 6.4 HEMI typically falls into a mid-range trim level, offering a good balance of features and value. Standard equipment generally includes air conditioning, power windows and locks, a basic infotainment system with a touchscreen display, and a rearview camera. Higher trim levels add features such as leather upholstery, heated and ventilated seats, a premium sound system, and advanced safety technologies like blind-spot monitoring and rear cross-traffic alert. Optional extras include a trailer brake controller, a fifth-wheel hitch, and various appearance packages.
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 design, optimized for load-carrying capacity. Air suspension is available as an option, providing adjustable ride height and improved comfort. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. An Anti-lock Braking System (ABS) is standard. The steering system utilizes a hydraulic power steering setup, offering responsive and precise control.
Market Reception & Comparison
The 6.4-liter HEMI V8-equipped Ram 3500 has generally received positive reviews from critics, who praise its powerful engine, smooth transmission, and comfortable ride. Compared to the diesel options, the HEMI is often seen as a more affordable and accessible choice for buyers who don’t require the ultimate in towing capacity or fuel economy. However, the diesel engines remain the preferred choice for those who frequently tow heavy loads or drive long distances. Fuel economy is a notable drawback compared to the diesel options, and maintenance costs can be higher due to the engine’s complexity.
Legacy
The 6.4-liter HEMI V8 has proven to be a reliable and durable engine in the Ram HD lineup. While not as fuel-efficient as newer engine technologies, it remains a popular choice for buyers who prioritize power and performance. On the used car market, Ram 3500 models equipped with this engine hold their value relatively well, particularly those that have been well-maintained. The TorqueFlite transmission is also known for its longevity, making these trucks a solid investment for buyers seeking a capable and dependable heavy-duty pickup.
