Powertrain & Engine Architecture
The heart of this Grand Cherokee variant is the 5.7-liter “HEMI” V8 engine, designated with the EZH engine code. This engine is a naturally aspirated, overhead valve (OHV) configuration, utilizing a cast iron block and aluminum cylinder heads. It employs multi-port fuel injection, delivering fuel directly into the intake ports. The engine’s 99.5mm bore and 90.9mm stroke contribute to its substantial displacement. The 10.5:1 compression ratio is a key factor in its power output. Paired with this engine is the Chrysler-developed 845RE eight-speed automatic transmission. This transmission is known for its smooth shifts and wide gear ratio spread, contributing to both performance and fuel efficiency. The transmission’s programming is tuned to balance responsiveness with comfort, making it suitable for both on-road cruising and off-road driving.
Driving Characteristics
The 5.7L V8 and eight-speed automatic combination delivers a noticeably more spirited driving experience compared to the 3.6L V6 models. Acceleration is brisk, and the engine provides ample torque for confident passing maneuvers and towing. The eight-speed transmission keeps the engine in its optimal power band, resulting in responsive acceleration. While not as overtly sporty as the SRT variants, this configuration offers a satisfying blend of power and refinement. The gear ratios are well-chosen for highway cruising, maintaining low engine speeds and contributing to reasonable fuel economy for a vehicle of this size and weight. Compared to manual transmission equipped Grand Cherokees (which were rare with this engine), the automatic offers greater convenience and ease of use, particularly in everyday driving situations.
Equipment & Trim Levels
The 5.7L V8 was typically offered on higher trim levels such as the Limited and Overland. Standard features included leather upholstery, heated front seats, a premium sound system, and a touchscreen infotainment system. The Overland trim added features like dual-pane panoramic sunroof, ventilated front seats, and upgraded interior trim. Optional extras included a rear entertainment system, adaptive cruise control, and a blind-spot monitoring system. The interior design featured a comfortable and well-appointed cabin, with a focus on quality materials and user-friendly controls.
Chassis & Braking
The Grand Cherokee’s chassis features an independent front suspension with double wishbones and an independent multi-link rear suspension. This setup provides a comfortable ride and good handling characteristics. The 5.7L models typically came equipped with larger brakes than the V6 models, featuring ventilated discs at all four corners. Anti-lock brakes (ABS) were standard, along with electronic stability control. The suspension tuning is geared towards providing a balance between on-road comfort and off-road capability. The standard tire size was 265/60R18, offering a good compromise between ride quality and traction.
Market Reception & Comparison
Critics generally praised the 5.7L V8-powered Grand Cherokee for its strong performance, comfortable ride, and well-equipped interior. Fuel economy was a common criticism, as expected for a vehicle of this size and with this engine. Compared to the 3.6L V6, the V8 offered a significant performance upgrade, but at the cost of increased fuel consumption. Compared to competitors like the BMW X5 and Mercedes-Benz GLE, the Grand Cherokee offered a more affordable price point and a more rugged, off-road-capable character. Reliability was generally considered good, although some owners reported minor issues with the infotainment system.
Legacy
The 5.7L V8-powered Grand Cherokee (WK2) remains a popular choice in the used car market. The HEMI engine is known for its durability and relatively straightforward maintenance. While fuel economy is not its strong suit, the engine’s robust power and towing capacity make it a desirable option for those who need a capable and comfortable SUV. The eight-speed automatic transmission has also proven to be reliable, with few reported issues. These vehicles continue to offer a compelling combination of luxury, performance, and capability, making them a solid choice for buyers seeking a well-rounded SUV.
