INTRODUCTION

The 2010-2012 RAM 1500 Regular Cab (DS) with the 5.7-liter Hemi V8 and automatic transmission represented a significant step forward in full-size truck design. Built on the redesigned 1HX0 platform, this generation of RAM 1500 aimed to deliver a more comfortable ride and improved interior quality compared to its predecessors. The Regular Cab configuration, with its two doors and limited rear seating, catered to buyers prioritizing functionality and affordability over passenger space. This trim level was positioned as the entry-level offering for those needing the Hemi’s power, making it a popular choice for work trucks and individuals who didn’t require the versatility of a crew cab.

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 naturally aspirated, overhead valve (OHV) design featuring multi-port fuel injection. The 5.7L Hemi produced 390 horsepower at 5,600 rpm and 407 lb-ft of torque at 4,000 rpm. The engine’s architecture is characterized by its robust cast iron block and aluminum cylinder heads. The automatic transmission paired with this engine was a five-speed unit, providing smooth and reliable shifting. While not the most technologically advanced transmission available at the time, it was well-suited to the engine’s power delivery and the truck’s intended use. The transmission was calibrated for a balance of fuel efficiency and towing capability.

Driving Characteristics

The 5.7 Hemi V8, coupled with the five-speed automatic, delivered strong acceleration and ample power for both daily driving and demanding tasks. While not as quick as some of the lighter-weight trucks on the market, the RAM 1500 offered a confident and capable driving experience. The automatic transmission’s gear ratios were optimized for towing and hauling, providing sufficient low-end torque. Compared to the 3.7L V6 or the later 3.6L Pentastar V6 options, the Hemi provided a noticeable performance advantage, especially when loaded or towing. However, it came at the cost of increased fuel consumption. The ride quality, thanks to the double wishbone front suspension and independent multi-link rear suspension, was generally comfortable, even when unladen.

Equipment & Trim Levels

The RAM 1500 Regular Cab (DS) 5.7 Hemi Automatic typically came standard with features such as air conditioning, a basic audio system, and vinyl upholstery. Higher trim levels, such as the SLT, offered upgrades like cloth or leather upholstery, power windows and locks, and a more advanced audio system. Optional extras included a trailer brake controller, upgraded wheels, and various appearance packages. The interior, while functional, was relatively basic in the standard configuration, focusing on durability and ease of cleaning. The dashboard layout was straightforward and user-friendly.

Chassis & Braking

The chassis of the 2010-2012 RAM 1500 was a body-on-frame construction, providing a solid and durable foundation. The front suspension utilized a double wishbone design, while the rear suspension featured an independent multi-link setup. This combination aimed to deliver a comfortable ride and good handling characteristics. Braking duties were handled by ventilated discs at the front and discs at the rear, equipped with an Anti-lock Braking System (ABS) as standard. The braking system was adequate for the truck’s weight and performance, providing confident stopping power in most conditions.

Market Reception & Comparison

The RAM 1500 Regular Cab 5.7 Hemi Automatic received generally positive reviews from automotive critics. It was praised for its powerful engine, comfortable ride, and spacious cabin. However, some critics noted its relatively high fuel consumption compared to V6-powered competitors. Compared to the Ford F-150 and Chevrolet Silverado, the RAM 1500 offered a unique blend of features and styling. The Hemi V8 provided a performance edge over the base engines offered by Ford and Chevrolet, but it also came with a higher price tag and lower fuel economy. The RAM 1500’s interior was often cited as being more refined than that of its competitors.

Legacy

The 5.7 Hemi V8 engine has proven to be a reliable and durable powertrain, and examples of the 2010-2012 RAM 1500 Regular Cab are still commonly found on the used car market today. While older models may require routine maintenance, the Hemi engine is generally known for its longevity. These trucks remain popular choices for those seeking a capable and affordable full-size pickup. The combination of power, capability, and relative affordability has ensured that the RAM 1500 Regular Cab 5.7 Hemi Automatic remains a desirable option for buyers looking for a workhorse truck.
