2010-2012 RAM 1500 Crew Cab (DS) 5.7 Hemi V8 (390 Hp) Automatic

Technical Specifications

The 2010-2012 RAM 1500 Crew Cab (DS) equipped with the 5.7-liter Hemi V8 engine and automatic transmission was a popular configuration of the second-generation (fourth overall) RAM 1500. This variant occupied a sweet spot in the lineup, offering a substantial increase in power and capability compared to the base V6 models, while remaining more accessible than the higher-trim level options. It was a key player in the full-size pickup truck segment, competing directly with the Ford F-150, Chevrolet Silverado, and GMC Sierra. The “DS” designation refers to the Crew Cab body style, offering spacious seating for up to six passengers.

Introduction

The 2010-2012 RAM 1500 Crew Cab (DS) with the 5.7-liter Hemi V8 and automatic transmission represented a significant step forward in comfort, capability, and refinement for the RAM brand. Building upon the foundation laid by the previous generation, this iteration of the 1500 offered a more car-like ride quality, a redesigned interior, and a powerful engine that was well-suited for both daily driving and demanding work tasks. The Crew Cab configuration, with its extended rear doors and spacious back seat, was particularly popular with families and those who frequently carried passengers. This model year marked a transition period for the RAM 1500, setting the stage for further improvements in subsequent years.

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 a 90-degree V8, providing a relatively compact footprint for its displacement. The cylinder bore measures 99.5 mm (3.92 inches) and the piston stroke is 90.9 mm (3.58 inches), resulting in a displacement of 5,654 cubic centimeters (345.03 cubic inches). The 10.5:1 compression ratio contributes to the engine’s power output. Paired with the engine was a five-speed automatic transmission, designed to provide smooth and efficient shifting. This transmission was chosen for its durability and ability to handle the engine’s substantial torque.

Driving Characteristics

The 5.7 Hemi V8 and five-speed automatic combination delivered a compelling driving experience. While not as quick as some of the lighter-weight competitors, the RAM 1500 offered ample power for accelerating from a standstill, merging onto highways, and towing trailers. The automatic transmission was tuned for smooth shifts and generally provided adequate response. Compared to the 3.7L V6 or the later 3.6L Pentastar V6 models, the 5.7 Hemi provided a noticeable increase in acceleration and overall performance. However, it wasn’t as fuel-efficient. The gear ratios in the five-speed automatic were optimized for both towing and cruising, providing a balance between power delivery and fuel economy. The truck’s substantial weight (2336 kg / 5150 lbs) did contribute to a slightly less agile feel compared to smaller pickups.

Equipment & Trim Levels

The RAM 1500 Crew Cab (DS) 5.7 Hemi typically came standard with a respectable array of features. These included air conditioning, power windows and locks, a basic audio system, and cloth upholstery. Higher trim levels, such as the Laramie and Limited, added features like leather upholstery, heated seats, a premium sound system, navigation, and advanced safety technologies. Optional extras included a sunroof, upgraded wheels, and various appearance packages. The interior design focused on providing a comfortable and functional space for both driver and passengers. The Crew Cab configuration offered generous legroom and headroom in both rows of seating.

Chassis & Braking

The RAM 1500 Crew Cab utilized a body-on-frame construction, providing a robust and durable platform. The front suspension featured a double wishbone design, while the rear suspension employed an independent multi-link setup. This suspension configuration aimed to deliver a comfortable ride quality while maintaining good handling characteristics. Braking duties were handled by ventilated discs at the front and solid discs at the rear. An Anti-lock Braking System (ABS) was standard equipment, enhancing safety and control during emergency braking situations. The truck rode on 265/70 R17 tires mounted on 7.0J x 17 inch wheels.

Market Reception & Comparison

The RAM 1500 Crew Cab 5.7 Hemi was generally well-received by automotive critics and consumers alike. It was praised for its powerful engine, comfortable ride, and spacious interior. However, some reviewers noted that its fuel economy was relatively poor compared to some of its competitors. Compared to the Ford F-150 with the 5.0-liter V8, the RAM 1500 offered a similar level of performance but was often perceived as having a more refined interior. Against the Chevrolet Silverado/GMC Sierra with the 5.3-liter V8, the RAM 1500 offered a comparable driving experience, with the choice often coming down to brand preference.

Legacy

The 5.7 Hemi V8 engine has proven to be a durable and reliable powertrain, and the 2010-2012 RAM 1500 Crew Cab remains a popular choice in the used car market. While older examples may require some maintenance, the engine is generally known for its longevity. The truck’s spacious interior and capable towing capacity continue to appeal to buyers seeking a versatile and practical full-size pickup. The 5.7 Hemi engine continued to be offered in the RAM 1500 for many years after 2012, undergoing further refinements and improvements. This particular generation of RAM 1500 helped solidify the brand’s reputation for building comfortable and capable trucks.
