Powertrain & Engine Architecture
At the heart of the RAM 1500 Quad Cab Long (DT) 5.7 HEMI V8 is the 5.7-liter naturally aspirated V8 engine. This engine, part of Chrysler’s HEMI family, is known for its robust construction and ample low-end torque. The engine code is typically found as part of the VIN and can vary slightly depending on the specific year and calibration. The 5.7L HEMI utilizes a multi-port fuel injection system, delivering fuel directly into the intake ports. It features a two-valve per cylinder configuration and a cast iron block with aluminum cylinder heads. A key feature of the HEMI engine is its Multi-Displacement System (MDS), which allows it to deactivate four cylinders under light load conditions to improve fuel economy. The engine is mated to a TorqueFlite 8-speed automatic transmission. This transmission provides smooth and efficient shifting, contributing to both performance and fuel economy. The 8-speed design allows for tighter gear ratios, keeping the engine in its optimal power band more frequently.
Driving Characteristics
The 5.7 HEMI V8 paired with the 8-speed automatic delivers a confident and capable driving experience. While not as quick as some of the higher-output RAM 1500 trims (like those with the 6.2L Supercharged HEMI), the 395 horsepower and 410 lb-ft of torque provide ample power for everyday driving and towing. The automatic transmission is well-tuned, offering smooth shifts and responsive acceleration. The gear ratios are optimized for both on-road cruising and off-road capability. Compared to manual transmission versions (which were less common), the automatic provides greater convenience and ease of use, particularly in stop-and-go traffic. The Quad Cab Long configuration, while offering more rear passenger space, does add some weight compared to the standard cab models, slightly impacting acceleration and fuel economy.
Equipment & Trim Levels
The RAM 1500 Quad Cab Long (DT) 5.7 HEMI V8 was available in a variety of trim levels, including Big Horn/Lone Star, Laramie, and Rebel. Standard equipment typically included 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 such as leather upholstery, heated and ventilated seats, a premium sound system, and advanced driver-assistance systems like adaptive cruise control and lane departure warning. Optional extras included a panoramic sunroof, a bed liner, and various off-road packages.
Chassis & Braking
The RAM 1500 Quad Cab Long (DT) utilizes a body-on-frame construction, providing a robust and durable platform. The front suspension features a coil spring, double wishbone design, while the rear suspension employs an independent multi-link setup. This suspension configuration delivers a comfortable ride quality, even when the truck is loaded with cargo or towing a trailer. 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 steering system is a rack-and-pinion setup with electric power steering, offering precise and responsive handling.
Market Reception & Comparison
The RAM 1500 Quad Cab Long (DT) 5.7 HEMI V8 was generally well-received by critics and consumers alike. It was praised for its comfortable ride, spacious interior, and powerful engine. Fuel economy, while improved over previous generations, remained a concern for some, particularly compared to smaller trucks or those with diesel engines. Compared to the 3.6L V6 versions, the 5.7 HEMI offered significantly more power and towing capacity, but at a higher price point. The 5.7 HEMI also provided a more refined driving experience than the available EcoDiesel engine, although the diesel offered superior fuel economy.
Legacy
The 5.7 HEMI V8 engine has a long and storied history in the RAM lineup, and the DT generation continued that legacy. The powertrain has proven to be relatively reliable, with proper maintenance. In the used car market, the RAM 1500 Quad Cab Long (DT) 5.7 HEMI V8 remains a popular choice, offering a compelling combination of capability, comfort, and value. Common maintenance items include regular oil changes, transmission fluid flushes, and spark plug replacements. The MDS system, while beneficial for fuel economy, has been known to occasionally experience issues, requiring attention. Overall, this variant represents a well-rounded and dependable full-size pickup truck.
