Powertrain & Engine Architecture
The heart of the Durango R/T is the 5.7-liter HEMI V8 engine. This engine, part of Chrysler’s well-established HEMI family, utilizes a cast iron block with aluminum cylinder heads. It features multi-port fuel injection and a variable valve timing (VVT) system to optimize performance and efficiency. The engine produces 360 horsepower at 5,150 rpm and 390 lb-ft of torque at 4,250 rpm. The “HEMI” designation refers to the hemispherical combustion chambers, a design intended to improve airflow and combustion efficiency. Paired with the engine is the TorqueFlite 8-speed automatic transmission, known for its smooth shifts and wide gear ratio spread. This transmission allows the engine to operate efficiently at highway speeds while providing quick acceleration when needed. The engine is longitudinally mounted, driving the rear wheels.
Driving Characteristics
The Durango R/T 5.7L Automatic delivers a noticeably more spirited driving experience than the lower-trim models. While not a sports car, the V8 provides ample power for confident acceleration and towing. The 8-speed automatic transmission is well-tuned, offering smooth and responsive shifts. The gear ratios are optimized for both everyday driving and hauling loads. Compared to a manual transmission Durango (not offered with this engine), the automatic prioritizes convenience and ease of use. The automatic does slightly diminish the feeling of direct control, but the performance trade-off is minimal for most drivers. The R/T’s weight (over 5,200 lbs) is noticeable, but the engine’s torque helps overcome this, providing strong pulling power.
Equipment & Trim Levels
The R/T trim included standard features such as leather upholstery, heated front seats, a Uconnect infotainment system with an 8.4-inch touchscreen, and a premium sound system. Additional standard equipment included a power liftgate, remote start, and a variety of driver-assistance features like blind-spot monitoring and rear cross-traffic alert. Optional extras for the R/T included a sunroof, navigation system, and advanced safety technologies like adaptive cruise control and forward collision warning. The interior typically featured a dark, sporty aesthetic with unique R/T badging.
Chassis & Braking
The Durango R/T utilizes a robust chassis designed to handle the V8’s power and the vehicle’s substantial weight. It features a double wishbone front suspension and an independent multi-link rear suspension, both incorporating a transverse stabilizer bar to reduce body roll. Braking duties are handled by ventilated discs at all four corners, with larger front rotors (350x32mm) than the base models. The R/T also includes an Anti-lock Braking System (ABS) as standard equipment. The suspension is tuned for a balance between comfort and handling, providing a reasonably compliant ride while maintaining good control in corners.
Market Reception & Comparison
The Durango R/T 5.7 HEMI was generally well-received by automotive critics. It was praised for its powerful engine, comfortable ride, and spacious interior. However, fuel economy was a common criticism, as expected for a large SUV with a V8 engine. Compared to the Durango GT (equipped with the V6 engine), the R/T offered significantly more performance but at the cost of increased fuel consumption. The R/T also positioned itself as a more affordable alternative to the higher-end SRT model, which boasted even more power and performance-focused features. Reliability reports generally indicate good long-term durability for the 5.7L HEMI engine and TorqueFlite transmission, though regular maintenance is crucial.
Legacy
The Durango R/T 5.7 HEMI V8 continues to be a popular choice in the used car market. Its combination of power, practicality, and relatively affordable price point makes it an attractive option for buyers seeking a capable and comfortable SUV. The 5.7L HEMI engine is known for its longevity and relatively straightforward maintenance. While fuel economy remains a concern, the Durango R/T’s overall value and robust powertrain ensure its continued presence on roads for years to come. The 2021 facelifted model benefits from updated technology and styling, further enhancing its appeal in the used car market.
