The 2025 RAM 3500 with the 6.4-liter HEMI V8 and TorqueFlite transmission represents a sweet spot in the heavy-duty Ram lineup for buyers prioritizing a balance of power, capability, and relative simplicity. The DT generation Ram trucks, launched in 2019, brought significant improvements in interior refinement, technology, and ride quality. The 2025 facelift builds on this foundation with updated styling and enhanced features. This specific configuration, with its dual rear wheels, is geared towards those who regularly tow extremely heavy loads – large trailers, equipment, or livestock – and require maximum stability and payload capacity. It sits above the base 6.4L HEMI models in terms of capability, but below the Cummins diesel-powered variants which offer even greater torque and towing capacity.
Powertrain & Engine Architecture
At the heart of this RAM 3500 is the 6.4-liter (391.59 cubic inch) 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. It produces 405 horsepower at 5600 rpm and 429 lb-ft of torque at 4000 rpm. 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 6.4L HEMI is known for its relatively simple design compared to some competitors, contributing to its reputation for reliability.
The engine is mated to the TorqueFlite 8-speed automatic transmission. This transmission is designed to handle the high torque output of the HEMI V8 and provides smooth and efficient shifting. The eight forward gears allow the engine to operate in its optimal power band more frequently, improving both acceleration and fuel economy. The TorqueFlite transmission also features a tow/haul mode, which alters shift points to provide more aggressive downshifts when towing heavy loads.
Driving Characteristics
The 6.4-liter HEMI V8 in the RAM 3500 DRW delivers ample power for most heavy-duty tasks. While it doesn’t possess the sheer torque of the Cummins diesel engine, it provides a responsive and engaging driving experience. Acceleration is brisk when unladen, and the truck maintains strong performance even when towing substantial loads. The 8-speed automatic transmission helps to keep the engine in its sweet spot, providing smooth and predictable power delivery. The dual rear wheel configuration significantly enhances stability when towing, reducing sway and improving overall control. Compared to the standard single-rear-wheel RAM 3500, the DRW model offers a noticeably more planted and confident feel when hauling heavy trailers. However, the DRW setup also results in a wider overall vehicle width, which can make maneuvering in tight spaces more challenging.
Equipment & Trim Levels
The 2025 RAM 3500 Regular Cab with the 6.4 HEMI V8 typically comes standard with a functional, work-oriented interior. Standard features generally include a user-friendly infotainment system with a touchscreen display, air conditioning, and basic cloth upholstery. Higher trim levels, such as the Laramie or Limited, add premium features like leather upholstery, heated and ventilated seats, a larger touchscreen display, and advanced safety technologies. Optional extras include a premium sound system, navigation, and various driver-assistance features. The Regular Cab configuration prioritizes functionality and cargo space over passenger comfort, making it ideal for work-focused buyers.
Chassis & Braking
The RAM 3500 chassis is built for durability and heavy-duty use. It features a robust frame and a heavy-duty suspension system. The front suspension utilizes coil springs and a rigid axle with a transverse stabilizer bar, while the rear suspension employs leaf springs. An optional air suspension system is available, providing adjustable ride height and improved ride comfort. Braking duties are handled by ventilated disc brakes on all four wheels. The front brakes measure 359.9×39.1 mm, while the rear brakes are 357.9×34 mm. An anti-lock braking system (ABS) is standard. The DRW configuration provides increased braking capacity and stability compared to single-rear-wheel models.
Market Reception & Comparison
The RAM 3500 with the 6.4-liter HEMI V8 has generally been well-received by critics and buyers alike. It’s praised for its strong performance, comfortable ride, and user-friendly technology. Compared to the Cummins diesel-powered RAM 3500, the 6.4 HEMI offers a lower initial cost and simpler maintenance requirements. However, it lacks the Cummins’ superior towing capacity and fuel efficiency. Compared to competitors like the Ford Super Duty and Chevrolet Silverado HD, the RAM 3500 is often lauded for its refined interior and comfortable ride quality. Fuel economy is typical for a heavy-duty truck, averaging around 14-17 mpg in combined driving.
Legacy
The 6.4-liter HEMI V8 has proven to be a reliable and durable engine in the RAM 3500. While not as fuel-efficient as diesel alternatives, it offers a compelling combination of power, simplicity, and affordability. On the used car market, RAM 3500s equipped with this powertrain generally hold their value well, particularly those that have been well-maintained. The TorqueFlite 8-speed automatic transmission has also proven to be a robust and reliable unit. This combination continues to be a popular choice for buyers seeking a capable and dependable heavy-duty pickup truck.
