Powertrain & Engine Architecture

At the heart of this RAM 1500 variant lies the 5.7-liter HEMI V8 engine, internally designated as the EZH. This engine is a member of Chrysler’s third-generation HEMI family, known for its robust construction and relatively simple design. The engine features overhead valve (OHV) valvetrain with two valves per cylinder. Fuel delivery is managed by a multi-port fuel injection system, providing precise fuel metering for optimal combustion. The 5.7L HEMI is notable for its Variable Valve Timing (VVT) technology, which adjusts valve timing based on engine speed and load, improving both performance and fuel efficiency. The engine’s 90-degree V8 configuration contributes to its smooth operation and inherent balance. The automatic transmission paired with this engine is a five-speed unit, designed to handle the engine’s substantial torque output. This transmission was chosen for its durability and ability to provide smooth shifts in both everyday driving and demanding work situations.

Driving Characteristics

The 5.7 Hemi V8, producing 390 horsepower and 407 lb-ft of torque, provided ample power for the RAM 1500. While not as quick as some of the lighter, sportier trucks on the market, the 1500 offered strong acceleration and impressive towing capacity. The five-speed automatic transmission was tuned for practicality rather than outright performance. Gear ratios were optimized for towing and hauling, resulting in a relatively conservative shift pattern. Compared to the manual transmission equipped models, the automatic offered greater convenience, especially in stop-and-go traffic. However, it did result in a slight decrease in fuel economy and a less engaging driving experience. The 4×4 system provided enhanced traction in inclement weather and off-road conditions, making this variant a versatile choice for a wide range of applications.

Equipment & Trim Levels

The RAM 1500 Regular Cab Long (DS) 5.7 Hemi 4×4 Automatic typically came standard with features such as air conditioning, power windows and locks, and a basic audio system. The interior was generally utilitarian, with durable cloth upholstery and a functional dashboard layout. Optional extras included upgraded audio systems, power-adjustable seats, cruise control, and a trailer brake controller. The DS trim level, representing the extended cab configuration, offered a small rear seat area suitable for occasional passengers or additional storage. The exterior typically featured black plastic bumpers and side moldings, with chrome accents available as optional upgrades.

Chassis & Braking

The RAM 1500’s chassis was built around a robust ladder frame, providing a solid foundation for its heavy-duty capabilities. The front suspension utilized a double wishbone design, while the rear suspension employed an independent multi-link setup. This combination offered a reasonable balance of ride comfort and handling. Braking duties were handled by ventilated disc brakes at all four corners, providing adequate stopping power for the truck’s weight. An Anti-lock Braking System (ABS) was standard, enhancing safety and control during emergency braking situations. The truck’s relatively high curb weight and long wheelbase contributed to its stable handling characteristics.

Market Reception & Comparison

The RAM 1500 with the 5.7 Hemi and automatic transmission was generally well-received by critics and consumers alike. It was praised for its powerful engine, comfortable ride, and impressive towing capacity. Fuel economy, however, was a common criticism, as the 5.7 Hemi was not known for its efficiency. Compared to the base V6 models, the Hemi offered a significant performance upgrade, but at the cost of increased fuel consumption. Compared to the diesel-powered RAM 1500s, the Hemi offered a lower initial cost but lacked the diesel’s superior fuel economy and torque. The 5.7 Hemi struck a balance between performance, cost, and convenience, making it a popular choice for buyers who needed a capable and reliable work truck.

Legacy

The 5.7 Hemi V8 engine has proven to be a remarkably durable and reliable powertrain. Many examples of the 2010-2012 RAM 1500 with this engine configuration are still on the road today, testament to its robust construction. While routine maintenance is essential, the engine is generally known for its longevity. In the used car market, these trucks remain popular due to their affordability and capability. However, potential buyers should be aware of potential issues such as oil consumption and the occasional failure of the variable valve timing (VVT) system. Overall, the RAM 1500 Regular Cab Long (DS) 5.7 Hemi V8 4×4 Automatic represents a solid and dependable full-size pickup truck that continues to offer value and utility to this day.
