Powertrain & Engine Architecture
At the heart of this RAM 1500 variant lies the 5.7-liter HEMI V8 engine. This engine, internally designated as part of the third-generation HEMI family, is a naturally aspirated, pushrod V8 known for its robust construction and ample low-end torque. The engine utilizes multi-port fuel injection and variable valve timing (VVT) to optimize performance and efficiency. The 5.7L HEMI produces 395 horsepower at 5,600 rpm and 410 lb-ft of torque at 3,950 rpm. The engine’s architecture features a cast iron block with aluminum cylinder heads, contributing to its durability. Paired with this engine is the ZF-sourced 8HP75 eight-speed automatic transmission. This transmission is renowned for its smooth shifting and wide gear ratio spread, enhancing both acceleration and fuel economy. The transmission features electronically controlled shifts and offers selectable drive modes, including a tow/haul mode optimized for heavy loads.
Driving Characteristics
The combination of the 5.7 HEMI and the eight-speed automatic delivers a driving experience that prioritizes usability and capability. While not as overtly sporty as some competitors, the RAM 1500 provides ample power for everyday driving and towing. The eight-speed transmission keeps the engine in its optimal power band, resulting in responsive acceleration. The Quad Cab configuration, with its longer wheelbase, contributes to a comfortable ride, particularly on rough roads. Compared to the 3.6-liter V6 option, the 5.7 HEMI offers significantly more power and torque, making it the preferred choice for those who frequently tow or haul heavy loads. Compared to the EcoDiesel variant, the HEMI offers a more traditional V8 sound and feel, but sacrifices some fuel economy. The automatic transmission, while smooth, doesn’t offer the same level of driver engagement as a manual transmission, but it simplifies operation, especially in demanding conditions.
Equipment & Trim Levels
The RAM 1500 Quad Cab Long (DT) 5.7 HEMI 4WD Automatic was available in a range of trim levels, including Big Horn/Lone Star, Laramie, and Limited. Standard equipment typically included features such as air conditioning, power windows and locks, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and a rearview camera. Higher trim levels added features like leather upholstery, heated and ventilated seats, a premium sound system, and advanced safety technologies such as blind-spot monitoring and rear cross-traffic alert. Optional extras included a panoramic sunroof, a bed liner, and various towing packages.
Chassis & Braking
The RAM 1500 utilizes a body-on-frame construction, providing a robust platform for heavy-duty use. The front suspension features a coil spring, double wishbone setup, while the rear suspension employs an independent multi-link design. This suspension configuration contributes to a comfortable ride and good handling characteristics. Braking duties are handled by ventilated discs at all four corners, providing ample stopping power. An anti-lock braking system (ABS) is standard, enhancing safety and control. The Quad Cab Long configuration benefits from a longer wheelbase, which improves stability and ride comfort.
Market Reception & Comparison
The RAM 1500, particularly with the 5.7 HEMI engine, consistently received positive reviews from automotive critics. It was praised for its comfortable ride, spacious interior, and strong towing capacity. The 5.7 HEMI engine was lauded for its smooth power delivery and reliability. Fuel economy, however, was a common criticism, as the V8 engine is less fuel-efficient than some of its competitors. Compared to the Ford F-150 and Chevrolet Silverado, the RAM 1500 often stood out for its refined interior and comfortable ride. The 5.7 HEMI offered a compelling alternative to the turbocharged V6 engines offered by Ford and GM, providing a more traditional V8 experience.
Legacy
The 5.7 HEMI V8 engine has a long and storied history in RAM trucks, and the version used in the 2018-2024 RAM 1500 Quad Cab Long (DT) continues to be regarded as a reliable and capable powerplant. These trucks have maintained relatively strong resale values, reflecting their durability and popularity. While newer RAM 1500 models offer more advanced technology and features, the DT generation remains a popular choice for buyers seeking a well-rounded and capable full-size pickup truck. Common maintenance items include regular oil changes, transmission fluid flushes, and spark plug replacements. Overall, the RAM 1500 Quad Cab Long (DT) 5.7 HEMI 4WD Automatic represents a solid and dependable choice in the used truck market.
