Powertrain & Engine Architecture
At the heart of this 2500 variant lies the 6.4-liter HEMI V8 engine, internally designated as part of the Chrysler Generation III HEMI family. This engine is a naturally aspirated, overhead valve (OHV) design featuring variable valve timing (VCT) for optimized performance and efficiency. The engine utilizes a multi-port fuel injection system, delivering fuel directly to each cylinder. The 6.4L HEMI produces 405 horsepower at 5,600 rpm and 429 lb-ft of torque at 4,000 rpm. This output is delivered through the TorqueFlite 8-speed automatic transmission, a robust unit designed to handle the substantial torque output of the engine. The TorqueFlite transmission offers smooth shifting and contributes to improved fuel economy compared to older automatic transmissions. The transmission is electronically controlled, adapting shift points based on driving conditions and throttle input.
Driving Characteristics
The 6.4-liter HEMI V8 paired with the 8-speed TorqueFlite transmission provides a confident and capable driving experience. While not as fuel-efficient as smaller engine options, this combination delivers ample power for towing and hauling heavy loads. The 8-speed transmission helps keep the engine in its optimal power band, providing responsive acceleration. Compared to the Cummins diesel options, the 6.4L HEMI offers a quieter and smoother driving experience, albeit with less low-end torque. The gear ratios are tuned for both on-road comfort and off-road capability, allowing for strong acceleration and controlled descents. The 4×4 system provides enhanced traction in challenging conditions.
Equipment & Trim Levels
The 2500 with the 6.4 HEMI typically falls into the mid-range of Ram’s trim level offerings. Standard equipment generally includes features like a user-friendly infotainment system with a touchscreen display, Apple CarPlay and Android Auto compatibility, 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 adaptive cruise control and lane departure warning. The Crew Cab configuration provides spacious seating for up to six passengers, making it suitable for both work and family use. Options often include upgraded wheels, exterior styling packages, and various convenience features.
Chassis & Braking
The RAM 2500/3500 utilizes a heavy-duty chassis designed to withstand the stresses of demanding work applications. The front suspension features a coil spring and rigid axle setup with a transverse stabilizer bar, while the rear suspension employs a similar configuration. This setup provides a comfortable ride while maintaining excellent load-carrying capacity. 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. Steering is accomplished via a hydraulic power steering system, offering a responsive and precise feel.
Market Reception & Comparison
The 6.4-liter HEMI V8-equipped RAM 2500 has generally received positive reviews for its blend of power, capability, and refinement. Critics have praised its smooth ride quality and user-friendly technology. Compared to the Cummins 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. Fuel economy is a common criticism, as the HEMI engine consumes more fuel than the diesel alternatives. However, the HEMI’s lower maintenance costs and simpler design can offset this disadvantage for some buyers.
Legacy
The 6.4-liter HEMI V8 has proven to be a reliable and durable powertrain in the RAM 2500/3500 lineup. While not as renowned for longevity as the Cummins diesel, the HEMI engine has a solid track record of providing years of dependable service. In the used car market, these models hold their value reasonably well, particularly those that have been well-maintained. The combination of a powerful V8 engine, a capable 4×4 system, and a spacious interior makes the 2025 RAM 2500/3500 Crew Cab Long II a compelling choice for buyers seeking a versatile and capable heavy-duty pickup truck.
