INTRODUCTION
The 2025 RAM 2500/3500 Crew Cab II with the 6.4 HEMI V8 and TorqueFlite transmission is a heavy-duty pickup truck designed for demanding tasks. It falls within the DT generation, which began in 2019, and benefits from a mid-cycle refresh for the 2025 model year. This refresh includes exterior styling updates, interior technology enhancements, and minor powertrain refinements. The 6.4-liter HEMI serves as the standard V8 engine option for both the 2500 and 3500 models, offering a balance of power and capability for those who don’t require the higher towing capacities of the Cummins diesel. The Crew Cab configuration provides ample passenger space, making it suitable for both work and family use.
Powertrain & Engine Architecture
At the heart of this RAM variant lies the 6.4-liter (391.59 cubic inches) HEMI V8 engine. This engine, internally designated as part of the HEMI family, utilizes a cast iron block with aluminum cylinder heads. It features a naturally aspirated configuration with multi-port fuel injection and overhead valve (OHV) valvetrain incorporating Variable Valve Timing (VCT). The engine produces 405 horsepower at 5600 rpm and 429 lb-ft of torque at 4000 rpm. The TorqueFlite 8-speed automatic transmission is specifically tuned to handle the engine’s output and the demands of heavy towing and hauling. This transmission features electronically controlled shifts and is known for its durability and smooth operation. Cylinder deactivation (MDS) is included, allowing the engine to operate on fewer cylinders during light-load conditions to improve fuel efficiency.
Driving Characteristics
The 6.4 HEMI V8 paired with the TorqueFlite 8-speed automatic delivers a confident and capable driving experience. While not as fuel-efficient as smaller engines or the diesel option, it provides ample power for everyday driving and demanding tasks. The 8-speed transmission helps keep the engine in its optimal power band, providing responsive acceleration. Compared to the Cummins diesel variants, the 6.4 HEMI offers a smoother, quieter ride and quicker acceleration in typical driving scenarios. However, it falls short in maximum towing capacity and fuel economy under heavy loads. The gear ratios are optimized for both on-road comfort and off-road capability, providing a good balance between performance and usability.
Equipment & Trim Levels
The 2500/3500 Crew Cab II with the 6.4 HEMI V8 is available in various trim levels, including Tradesman, Big Horn/Laramie, and Limited. Standard equipment typically includes features like air conditioning, a user-friendly infotainment system with a touchscreen display, Bluetooth connectivity, 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 sunroof, upgraded wheels, and various appearance packages.
Chassis & Braking
The RAM 2500/3500 utilizes a robust chassis designed to withstand heavy loads and demanding conditions. The front suspension features a coil spring and rigid axle setup with a transverse stabilizer bar, while the rear suspension also employs a rigid axle configuration with coil springs and a stabilizer bar. Braking duties are handled by ventilated disc brakes on all four wheels, providing ample stopping power. The braking system is assisted by an Anti-lock Braking System (ABS) for enhanced safety. Steering is accomplished via a hydraulic power steering system with a cone worm and recirculation balls mechanism.
Market Reception & Comparison
The 6.4 HEMI V8-equipped RAM 2500/3500 has generally received positive reviews from automotive critics. It’s praised for its strong performance, comfortable ride, and user-friendly technology. Compared to the Cummins diesel variants, it’s often seen as a more affordable and accessible option for buyers who don’t require the highest towing capacities. Fuel economy is a common criticism, as the 6.4 HEMI is less efficient than the diesel engine, especially under heavy loads. However, its lower initial cost and simpler maintenance requirements make it an attractive alternative for many buyers.
Legacy
The 6.4 HEMI engine has proven to be a reliable and durable powertrain in the RAM 2500/3500 lineup. While long-term reliability data for the 2025 facelift model is still emerging, previous generations of this engine have demonstrated a good track record. In the used car market, these trucks hold their value relatively well, particularly those in good condition with well-maintained service records. The combination of power, capability, and relative affordability makes the 6.4 HEMI V8 a popular choice among truck buyers seeking a robust and versatile heavy-duty pickup.
