The RAM 1500 Regular Cab (DS) equipped with the 5.7 Hemi V8 engine and a four-wheel drive (4×4) automatic transmission was a mainstay of the full-size pickup truck market in North America from 2010 to 2012. Representing the second generation of the redesigned 1500 series (following the split from Dodge), this configuration offered a balance of capability, power, and relative affordability within the RAM lineup. It served as a workhorse for individuals and businesses needing a robust truck for hauling and towing, while also providing a comfortable ride for daily use. This particular variant occupied a mid-range position, slotting below the more luxurious trims and heavy-duty models, but offering significantly more power and capability than the base V6 options.

Powertrain & Engine Architecture
The heart of this RAM 1500 variant is the 5.7-liter HEMI V8 engine, designated with the engine code EZH. This engine is a member of Chrysler’s third-generation HEMI family, known for its robust construction and strong low-end torque. It features a cast iron block with aluminum cylinder heads, and utilizes a pushrod valve train (OHV) for simplicity and reliability. The engine employs multi-port fuel injection, delivering fuel directly into the intake ports, and is naturally aspirated, relying on atmospheric pressure for air intake. The 5.7L HEMI is notable for its Multi-Displacement System (MDS), a fuel-saving technology that seamlessly switches between eight and four cylinder operation under light load conditions. This system contributes to improved fuel economy without sacrificing performance when needed. The engine is mated to a five-speed automatic transmission, providing smooth and efficient gear changes. This transmission was specifically tuned to handle the engine’s substantial torque output and provide adequate performance for both everyday driving and demanding tasks like towing.
Driving Characteristics
The 5.7 Hemi V8 paired with the five-speed automatic delivers a driving experience that prioritizes capability and usability. While not as quick or agile as lighter-duty trucks or those equipped with higher-output engines, the 390 horsepower and 407 lb-ft of torque provide ample power for accelerating from a standstill, merging onto highways, and tackling steep inclines. The automatic transmission’s gear ratios are optimized for towing and hauling, providing strong low-end grunt. Compared to the base V6 models, the Hemi offers a significantly more confident and effortless driving experience, especially when carrying a load or towing a trailer. The 4×4 system provides enhanced traction in inclement weather or off-road conditions. However, the weight of the truck and the inherent characteristics of the automatic transmission mean that it doesn’t feel as responsive or engaging as a manual transmission equipped model.
Equipment & Trim Levels
The RAM 1500 Regular Cab (DS) with the 5.7 Hemi and 4×4 typically came standard with features like air conditioning, power windows and locks, a basic audio system, and a tilt steering wheel. The interior upholstery was typically vinyl or cloth, depending on the specific package. Optional extras included upgraded audio systems, power seats, cruise control, and various towing packages. The “DS” designation generally indicated a mid-level trim, offering a step up in features and comfort compared to the base models, but falling short of the luxury offered by higher trims like the Laramie.
Chassis & Braking
The RAM 1500 Regular Cab (DS) utilizes a body-on-frame construction, providing a robust and durable platform for heavy-duty use. The front suspension features a double wishbone design, while the rear suspension employs an independent multi-link setup, offering a comfortable ride quality even when the truck is loaded. Braking duties are handled by ventilated discs at the front and solid discs at the rear. An Anti-lock Braking System (ABS) is standard, enhancing safety and control during emergency braking situations. The truck’s relatively heavy weight necessitates a robust braking system to ensure adequate stopping power.
Market Reception & Comparison
The 5.7 Hemi-equipped RAM 1500 was generally well-received by critics and consumers alike. It was praised for its powerful engine, comfortable ride, and overall capability. Fuel economy, however, was a common criticism, with the 14.1 US mpg in urban driving being relatively low compared to some competitors. Compared to other trims in the RAM 1500 lineup, the 5.7 Hemi offered a compelling balance of performance and value. The V6 models were more fuel-efficient but lacked the power for demanding tasks, while the higher-end trims were significantly more expensive. Reliability was generally considered good, although some owners reported issues with the MDS system and occasional electrical glitches.
Legacy
The 5.7 Hemi V8 engine has proven to be a durable and reliable powerplant, and examples of the 2010-2012 RAM 1500 equipped with this engine continue to be found on the used car market today. While older models may require some maintenance and repairs, the engine itself is generally considered to be long-lasting. The combination of power, capability, and relative affordability has made this variant a popular choice for truck buyers seeking a dependable workhorse. The 2010-2012 RAM 1500, particularly with the 5.7 Hemi, represents a significant step forward in truck design and capability, solidifying RAM’s position as a leading manufacturer of full-size pickup trucks.
