The Dodge Durango II, specifically the facelifted version produced from 2006 to 2008, represented a significant evolution for Dodge’s full-size SUV. This generation, internally designated HB, aimed to blend truck-based durability with more refined on-road manners. The 5.7 HEMI V8 with an automatic transmission and all-wheel drive (AWD) configuration was a top-tier offering within the Durango II lineup, positioned as the performance and capability leader. It catered to buyers needing substantial towing capacity and robust all-weather performance, while still offering a comfortable family vehicle. This variant built upon the foundation of the original Durango, offering increased refinement and power.

Technical Specifications

INTRODUCTION

The 2006-2008 Dodge Durango II 5.7 HEMI V8 AWD Automatic represented the pinnacle of capability for the second-generation Durango. Built on the HB platform, which was shared with the Dakota pickup truck, the Durango II aimed to provide a more comfortable and refined experience than its predecessor. The facelift in 2006 brought updated styling and some interior enhancements. This particular variant, equipped with the 5.7-liter HEMI and automatic transmission, was designed for buyers who needed substantial towing capacity, all-weather traction, and a powerful driving experience. It sat at the top of the Durango lineup, above the 3.7L V6 and 4.7L V8 models.

Powertrain & Engine Architecture

The heart of this Durango is the 5.7-liter HEMI V8 engine, designated as the EZB engine code. This engine is a 90-degree OHV (Overhead Valve) design, featuring multi-port fuel injection. The HEMI architecture is characterized by its hemispherical combustion chambers, which contribute to increased airflow and improved efficiency. The 5.7L HEMI produced 335 horsepower at 5200 rpm and 502 Nm (370.26 lb-ft) of torque at 4200 rpm. A key feature of this engine is the Multi-Displacement System (MDS), a cylinder deactivation system that shuts down four cylinders during light-load cruising to improve fuel economy. The engine is paired with a 5-speed automatic transmission, providing smooth and responsive shifting. The transmission was tuned to balance performance and fuel efficiency, with gear ratios optimized for both towing and everyday driving.

Driving Characteristics

The 5.7 HEMI-equipped Durango offered a noticeably more powerful driving experience compared to the lower-trim models. Acceleration was brisk, and the engine provided ample torque for merging onto highways and passing other vehicles. The automatic transmission shifted smoothly, although it wasn’t as sporty or quick-shifting as some of the transmissions found in performance-oriented SUVs. The AWD system provided excellent traction in various weather conditions, making it a capable vehicle for those living in areas with snow or rain. However, the Durango’s substantial weight (2300 kg / 5070.63 lbs) did impact handling, making it feel less agile than lighter SUVs. The ride quality was generally comfortable, thanks to the torsion bar front suspension and coil spring rear suspension, but it could be somewhat bouncy over rough roads.

Equipment & Trim Levels

The 5.7 HEMI AWD Durango typically came well-equipped, although specific features varied depending on optional packages. Standard equipment generally included air conditioning, power windows and locks, a CD player, and cloth upholstery. Higher trim levels, such as the Limited, added features like leather upholstery, heated seats, a premium sound system, and a sunroof. Optional extras included a navigation system, rear-seat entertainment system, and upgraded wheels. The interior design was functional and straightforward, with a focus on durability and ease of use.

Chassis & Braking

The Durango II utilized a body-on-frame construction, providing a robust and durable chassis. The front suspension featured an independent torsion bar setup with a double wishbone design and a transverse stabilizer bar. The rear suspension employed a rigid axle configuration with coil springs and a transverse stabilizer bar. This setup provided a good balance of ride comfort and load-carrying capacity. Braking duties were handled by ventilated discs at the front (336x28mm) and discs at the rear (352x22mm). An Anti-lock Braking System (ABS) was standard, enhancing safety and control during hard braking. The hydraulic power steering provided responsive and predictable steering feel.

Market Reception & Comparison

The 2006-2008 Dodge Durango 5.7 HEMI AWD Automatic received generally positive reviews from automotive critics. It was praised for its powerful engine, spacious interior, and capable towing capacity. However, some critics noted its relatively poor fuel economy and somewhat dated interior design. Compared to the 3.7L V6 and 4.7L V8 models, the 5.7 HEMI offered significantly more power and torque, making it the preferred choice for buyers who needed to tow heavy loads or drive in challenging conditions. The 4.7L V8 offered a compromise between power and fuel economy, while the 3.7L V6 was the most fuel-efficient option but lacked the performance of the larger engines.

Legacy

The 5.7 HEMI-equipped Durango II has proven to be a relatively reliable vehicle, although like any used vehicle, it’s important to consider maintenance history. The HEMI engine is known for its durability, but regular maintenance, including oil changes and tune-ups, is crucial. The automatic transmission is also generally reliable, but it’s important to check for any signs of slipping or rough shifting. Today, these Durangos can be found on the used car market at relatively affordable prices, making them an attractive option for buyers seeking a capable and spacious SUV. While fuel economy isn’t its strong suit, the 5.7 HEMI Durango remains a popular choice for those who need a powerful and versatile vehicle.
