Introduction
The 2025 RAM 2500/3500 Crew Cab Long II, specifically the 2500 variant with the 6.4-liter HEMI V8 and TorqueFlite transmission, is a heavy-duty pickup truck designed for demanding tasks. Built on the DT platform, which debuted in 2019, the 2025 model represents a significant facelift, incorporating updated styling cues, enhanced interior features, and improved technology. This configuration is particularly well-suited for owners who require substantial towing and payload capacity but prefer the relative simplicity and responsiveness of a gasoline engine over a diesel. The Crew Cab Long configuration provides ample passenger space and a long bed for versatile cargo hauling.
Powertrain & Engine Architecture
At the heart of this RAM 2500 is the 6.4-liter (391.59 cubic inches) HEMI V8 engine, internally designated as part of the Generation III HEMI family. This engine produces 405 horsepower at 5600 rpm and 429 lb-ft of torque at 4000 rpm. It features a cast iron block, aluminum cylinder heads, and a robust crankshaft designed for high-stress applications. The engine utilizes a multi-port fuel injection system and overhead valve (OHV) valvetrain with variable valve timing (VCT) to optimize performance and efficiency. The TorqueFlite 8-speed automatic transmission is a key component, providing smooth and efficient power delivery. This transmission is known for its durability and ability to handle the high torque output of the HEMI V8. The engine’s longitudinal mounting and rear-wheel-drive configuration are standard, with four-wheel drive available as an option.
Driving Characteristics
The 6.4-liter HEMI V8 paired with the TorqueFlite 8-speed automatic delivers a responsive and capable driving experience. While not as fuel-efficient as smaller engines or diesel alternatives, it provides ample power for towing and hauling heavy loads. The 8-speed transmission helps to keep the engine in its optimal power band, resulting in strong acceleration and confident passing maneuvers. Compared to the Cummins diesel options, the HEMI offers a smoother and quieter ride, with less engine vibration. However, it lacks the sheer torque of the diesel, which is particularly noticeable when towing extremely heavy trailers. The gear ratios are tuned for a balance of towing performance and on-road drivability, providing a comfortable cruising experience at highway speeds.
Equipment & Trim Levels
The RAM 2500 6.4 HEMI typically comes standard with a well-equipped interior, including cloth upholstery, air conditioning, a user-friendly infotainment system with a touchscreen display, and a rearview camera. Higher trim levels, such as Laramie, Longhorn, and Limited, add premium features like leather upholstery, heated and ventilated seats, a premium sound system, and advanced safety technologies. Optional extras include a sunroof, navigation system, and various driver-assistance features. The Crew Cab configuration provides generous space for passengers in both the front and rear seats, making it ideal for families or work crews.
Chassis & Braking
The RAM 2500 features a heavy-duty chassis designed to withstand the stresses of demanding work. It utilizes a coil spring front suspension with a rigid axle and a transverse stabilizer bar, providing a comfortable ride and good handling characteristics. The rear suspension also employs a rigid axle with coil springs and a transverse stabilizer bar. 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. Steering is accomplished via a hydraulic power steering system, offering a responsive and precise feel.
Market Reception & Comparison
The RAM 2500 6.4 HEMI has generally received positive reviews from critics and owners alike. It is praised for its powerful engine, smooth transmission, comfortable ride, and well-appointed interior. Compared to the Cummins diesel options, the HEMI is often seen as a more affordable and user-friendly choice for those who don’t require the maximum towing capacity. Fuel economy is a common criticism, as the HEMI V8 is less efficient than diesel engines. However, the HEMI’s lower maintenance costs and simpler design can offset this disadvantage over the long term. Compared to competitors like the Ford Super Duty and Chevrolet Silverado HD, the RAM 2500 is often lauded for its refined interior and comfortable ride quality.
Legacy
The 6.4-liter HEMI V8 and TorqueFlite transmission combination has proven to be a reliable and durable powertrain in the RAM 2500/3500. While long-term reliability data is still emerging for the 2025 facelift, previous generations of this powertrain have demonstrated a strong track record. On the used car market, these trucks hold their value relatively well, particularly those that have been well-maintained. The combination of power, capability, and comfort makes the RAM 2500 6.4 HEMI a popular choice for buyers seeking a versatile and dependable heavy-duty pickup truck.
