Powertrain & Engine Architecture

The heart of the Durango R/T is the 5.7-liter HEMI V8 engine, internally designated as the Apache engine. This naturally aspirated powerplant utilizes a cast iron block with aluminum cylinder heads. It features a multi-point fuel injection system and a variable valve timing (VVT) system to optimize performance and fuel efficiency. The engine produces 360 horsepower at 5,150 rpm and 390 lb-ft of torque at 4,250 rpm. The engine’s architecture is a traditional overhead valve (OHV) configuration. The engine is mated to a TorqueFlite 8-speed automatic transmission, providing smooth and responsive shifting. This transmission is known for its durability and ability to handle the engine’s substantial torque output. The drivetrain is an all-wheel-drive (AWD) system, providing enhanced traction and stability in various driving conditions.

Driving Characteristics

The Durango R/T 5.7L Automatic delivers a compelling driving experience, balancing power and refinement. While not as aggressively tuned as the SRT or Hellcat models, the R/T offers brisk acceleration and ample power for everyday driving and towing. The 8-speed automatic transmission is well-programmed, providing smooth gear changes and keeping the engine in its optimal power band. The AWD system enhances grip, particularly in inclement weather. Compared to the base V6 models, the R/T provides a noticeable increase in performance. However, it doesn’t quite match the raw acceleration of the higher-performance trims. The gear ratios are optimized for both acceleration and highway cruising, offering a comfortable and capable ride.

Equipment & Trim Levels

The Durango R/T comes standard with a range of features, including leather upholstery, heated front seats, a Uconnect infotainment system with an 8.4-inch touchscreen, Apple CarPlay and Android Auto compatibility, and a premium sound system. Additional standard equipment includes keyless entry, remote start, and a power liftgate. Optional extras for the R/T trim often included a sunroof, navigation system, advanced safety features like adaptive cruise control and blind-spot monitoring, and upgraded interior trim packages. The interior typically features a sporty aesthetic with unique R/T badging and accents.

Chassis & Braking

The Durango R/T utilizes a robust chassis with a double wishbone front suspension and an independent multi-link rear suspension. This setup provides a comfortable ride while maintaining good handling characteristics. The R/T is equipped with ventilated disc brakes on all four wheels, providing ample stopping power. The front brakes measure 350x32mm, while the rear brakes are 330x22mm. An Anti-lock Braking System (ABS) is standard. The suspension is tuned to balance ride comfort and handling, offering a stable and controlled driving experience.

Market Reception & Comparison

The Durango R/T 5.7L Automatic was generally well-received by automotive critics. It was praised for its powerful engine, comfortable ride, and spacious interior. Fuel economy, however, was a common criticism, as expected for a large V8-powered SUV. Compared to the V6-powered Durango models, the R/T offered a significant performance upgrade, but at a higher price point. Against competitors like the Chevrolet Tahoe and Ford Expedition, the Durango R/T offered a more engaging driving experience and a more refined interior. Reliability reports suggest that the 5.7L HEMI engine and TorqueFlite transmission are generally reliable, but regular maintenance is crucial.

Legacy

The Durango R/T 5.7L Automatic has established itself as a popular choice in the used car market. Its combination of power, space, and features makes it a versatile option for families and individuals alike. The 5.7L HEMI engine is known for its longevity and relatively straightforward maintenance. While fuel economy is not its strong suit, the Durango R/T remains a compelling option for those seeking a capable and comfortable full-size SUV with a proven powertrain.
