INTRODUCTION
The 2017-2021 Jeep Grand Cherokee 5.7 V8 4×4 Automatic represents a refined iteration of a proven formula. Built on the WK2 platform, this facelift brought updated styling, enhanced technology, and continued improvements to the already capable Grand Cherokee. The 5.7-liter HEMI V8 engine, coupled with the eight-speed automatic transmission and Jeep’s Quadra-Trac II 4×4 system, provided a robust and versatile powertrain suitable for both on-road comfort and off-road adventures. This configuration was positioned as a premium offering, appealing to buyers seeking a powerful and luxurious SUV with genuine four-wheel-drive capability.
Powertrain & Engine Architecture
At the heart of this Grand Cherokee variant lies the 5.7-liter HEMI V8 engine, designated with the code EZH. This engine is a naturally aspirated, overhead valve (OHV) design featuring variable valve timing (VVT). The engine utilizes a multi-port fuel injection system to deliver fuel to the cylinders. The 5.7L HEMI benefits from Chrysler’s Cylinder Deactivation System (MDS), which shuts down four cylinders during light-load cruising to improve fuel economy. The eight-speed automatic transmission (845RE) is a crucial component, offering smooth and efficient gear changes. This transmission features a wide gear ratio spread, optimizing both acceleration and highway cruising. The Quadra-Trac II 4×4 system provides full-time four-wheel drive with an electronic limited-slip rear differential, enhancing traction in various conditions.
Driving Characteristics
The 5.7-liter V8 delivers a noticeable performance advantage over the lower-displacement engine options. With 360 horsepower and 520 lb-ft of torque, the Grand Cherokee offers strong acceleration and effortless highway cruising. The eight-speed automatic transmission is well-tuned, providing quick and responsive shifts. While not as fuel-efficient as the V6 models, the V8 provides a more satisfying driving experience, particularly when towing or navigating challenging terrain. The 4×4 system provides excellent traction in slippery conditions, and the available air suspension (on higher trims) further enhances ride comfort and off-road capability. Compared to manual transmission variants (which were not commonly offered with the V8), the automatic provides a more relaxed and convenient driving experience, prioritizing ease of use over outright driver engagement.
Equipment & Trim Levels
The 5.7 V8 4×4 Automatic was typically offered on higher trim levels such as Limited, Trailhawk, and Summit. Standard features generally included leather upholstery, heated front seats, a premium sound system, and a large touchscreen infotainment system with navigation. Higher trims added features like ventilated front seats, a panoramic sunroof, adaptive cruise control, and advanced safety technologies. Optional extras included a rear-seat entertainment system, premium leather options, and various appearance packages. The Trailhawk trim, specifically, was geared towards off-road enthusiasts, featuring enhanced four-wheel-drive capabilities, skid plates, and all-terrain tires.
Chassis & Braking
The Grand Cherokee’s chassis is a robust unibody construction designed to handle both on-road and off-road stresses. The front suspension utilizes a coil spring, double wishbone setup with a transverse stabilizer bar. The rear suspension employs an independent multi-link spring suspension, also with a stabilizer bar. Air suspension was available as an option on higher trims, providing adjustable ride height and improved ride comfort. Braking duties are handled by ventilated discs on all four wheels, measuring 350x32mm at the front and 330x32mm at the rear. The system is equipped with ABS (Anti-lock Braking System) and electronic stability control.
Market Reception & Comparison
The 5.7 V8 4×4 Automatic Grand Cherokee was generally well-received by critics and consumers alike. It was praised for its powerful engine, comfortable ride, and capable four-wheel-drive system. Compared to the V6 models, the V8 offered a significant performance boost, but at the expense of fuel economy. Against competitors like the Chevrolet Tahoe and Ford Expedition, the Grand Cherokee offered a more refined driving experience and a more luxurious interior. However, those competitors often provided more cargo space and third-row seating. Reliability was generally good, although some owners reported minor issues with the infotainment system and electrical components.
Legacy
The 2017-2021 Jeep Grand Cherokee 5.7 V8 4×4 Automatic remains a popular choice in the used car market. The HEMI V8 engine is known for its durability and relatively straightforward maintenance. While fuel economy is not its strong suit, the engine’s robust power and torque make it a capable tow vehicle and a satisfying daily driver. The WK2 generation Grand Cherokee, as a whole, has established a reputation for reliability and longevity, and the 5.7 V8 variant continues to hold its value well, appealing to buyers who prioritize performance, capability, and a touch of luxury.
