The RAM 2500/3500 Regular Cab II (DT facelift, introduced for the 2025 model year) represents the latest iteration of Ram’s heavy-duty pickup truck lineup. This particular variant features the 6.4-liter HEMI V8 engine paired with the TorqueFlite eight-speed automatic transmission. Positioned as a strong mid-range offering, it slots between the base Cummins diesel engine options and the more powerful High-Output Cummins diesel. The 2025 facelift brings updated styling, enhanced technology, and refinements to the interior, building upon the already robust foundation of the DT generation which began in 2019. This configuration is primarily aimed at buyers needing substantial towing and payload capacity without the added cost and complexity of the diesel powertrains.

Powertrain & Engine Architecture
The heart of this RAM 2500/3500 variant is the 6.4-liter (392 cubic inch) HEMI V8 engine. This engine, internally designated as part of the Generation III HEMI family, is a pushrod (OHV) design featuring variable valve timing (VCT). The multi-port fuel injection system delivers fuel directly to each cylinder, optimizing combustion. The 6.4L HEMI benefits from a cylinder deactivation system (MDS) which shuts down four cylinders during light load conditions to improve fuel economy. The TorqueFlite 8HP75 eight-speed automatic transmission is specifically tuned for heavy-duty applications, providing smooth shifts and optimized gear ratios for towing and hauling. This transmission is known for its durability and ability to handle the high torque output of the HEMI V8.
Driving Characteristics
The 6.4L HEMI V8 with the TorqueFlite automatic delivers a balance of power and usability. While not as fuel-efficient as the diesel options, it provides ample torque for most towing and hauling needs. The eight-speed transmission keeps the engine in its optimal power band, resulting in responsive acceleration. Compared to the base gasoline engine, this 6.4L offers a significant performance upgrade. However, it doesn’t match the sheer pulling power of the Cummins diesel engines, particularly at higher weights. The automatic transmission provides convenient operation, especially in stop-and-go traffic or when navigating challenging terrain. The gear ratios are well-suited for both on-road cruising and off-road crawling.
Equipment & Trim Levels
The 2500/3500 with the 6.4L HEMI V8 was typically offered in various trim levels, including Tradesman, Big Horn/Laramie, and Limited. The base Tradesman trim provided a work-oriented interior with vinyl upholstery and basic features. Higher trims like the Big Horn/Laramie added features such as cloth or leather upholstery, upgraded infotainment systems, and more refined interior appointments. The Limited trim represented the pinnacle of luxury, offering premium leather, wood trim, and advanced technology features. Standard equipment generally included air conditioning, power windows and locks, and a basic audio system. Optional extras included a premium sound system, navigation, heated and ventilated seats, and a variety of driver-assistance technologies.
Chassis & Braking
The RAM 2500/3500 utilizes a robust chassis designed to withstand heavy loads. The front suspension features a coil spring and rigid axle setup with a transverse stabilizer bar. The rear suspension also employs a rigid axle configuration with coil springs and a transverse stabilizer bar. Braking duties are handled by ventilated discs at all four corners, providing ample stopping power. An Anti-lock Braking System (ABS) is standard. Steering is accomplished via a hydraulic power steering system with a cone worm and recirculation balls mechanism. The heavy-duty suspension and braking components are designed to provide a comfortable ride while maintaining stability and control when towing or hauling.
Market Reception & Comparison
The 6.4L HEMI V8-equipped RAM 2500/3500 received generally positive reviews. Critics praised its strong performance, comfortable ride, and user-friendly features. Compared to the diesel options, it was often seen as a more affordable and simpler alternative, albeit with lower fuel economy and towing capacity. Against competitors like the Ford Super Duty and Chevrolet Silverado/GMC Sierra, the RAM 2500/3500 offered a compelling combination of capability, comfort, and value. Fuel economy typically ranged from 14-17 mpg in combined driving, depending on driving conditions and load. Reliability has been generally good, with the TorqueFlite transmission proving to be particularly durable.
Legacy
The 6.4L HEMI V8 and TorqueFlite transmission combination has proven to be a reliable and capable powertrain in the RAM 2500/3500. On the used car market, these trucks hold their value relatively well, particularly those that have been well-maintained. The engine is known for its longevity and relatively straightforward maintenance requirements. While the diesel engines remain popular for heavy-duty applications, the 6.4L HEMI V8 provides a viable alternative for buyers who prioritize gasoline power and a more accessible price point. The DT generation RAM 2500/3500, including this 6.4L variant, continues to be a popular choice for those needing a powerful and capable pickup truck.
