Powertrain & Engine Architecture

The heart of this Grand Cherokee variant is the 3.0-liter V6 MultiJet diesel engine, designated with the engine code EXN. This engine is a common-rail direct injection diesel, utilizing piezoelectric injectors for precise fuel delivery. The engine features a variable geometry turbocharger (VGT) and an intercooler to maximize power and efficiency. The DOHC valvetrain, with four valves per cylinder, contributes to improved breathing and overall performance. The 8-speed automatic transmission, sourced from ZF (8HP70), is a key component, known for its smooth shifting and wide gear ratio spread. This transmission is designed to optimize fuel economy and provide responsive acceleration. The engine produces 250 horsepower at 3600 rpm and a substantial 570 Nm (420 lb-ft) of torque at 2000 rpm, making it well-suited for towing and off-road driving.

Driving Characteristics

The 3.0L V6 MultiJet with the 8-speed automatic delivers a comfortable and capable driving experience. While not as overtly powerful as the HEMI V8, the diesel engine provides ample torque for everyday driving and highway cruising. The automatic transmission is well-programmed, offering smooth gear changes and quick downshifts when needed. Acceleration from 0-60 mph takes around 7.8 seconds, which is respectable for a vehicle of this size and weight. The wide gear ratio spread of the 8-speed transmission helps to keep the engine in its optimal power band, resulting in good responsiveness. Compared to the manual transmission versions, the automatic offers greater convenience, especially in urban traffic. However, some drivers may find the automatic slightly less engaging than the manual.

Equipment & Trim Levels

The 3.0 V6 MultiJet Automatic typically came equipped with a generous array of standard features. These included leather upholstery, dual-zone automatic climate control, a touchscreen infotainment system with navigation, and a rearview camera. Higher trim levels, such as the Limited and Trailhawk, added features like heated and ventilated front seats, a panoramic sunroof, premium audio systems, and advanced safety technologies like adaptive cruise control and blind-spot monitoring. Optional extras included air suspension, which provided a more comfortable ride and increased off-road capability, and a rear-seat entertainment system.

Chassis & Braking

The Grand Cherokee IV features an independent front suspension with a double wishbone setup and a multi-link independent rear suspension. The suspension is tuned to provide a balance between ride comfort and handling. Air suspension was available as an option, offering adjustable ride height and improved off-road performance. Braking duties are handled by ventilated discs on all four wheels, providing ample stopping power. The braking system is equipped with ABS (Anti-lock Braking System) and electronic stability control. Stabilizer bars are fitted to both the front and rear axles to reduce body roll during cornering.

Market Reception & Comparison

The 3.0 V6 MultiJet Automatic Grand Cherokee was generally well-received by automotive critics. It was praised for its fuel efficiency, comfortable ride, and capable performance. Compared to the 5.7L HEMI V8, the diesel offered significantly better fuel economy, making it a more practical choice for drivers who prioritize efficiency. However, the HEMI V8 provided more raw power and a more traditional V8 sound. The diesel also offered a quieter and more refined driving experience than the HEMI. Reliability has been generally good, although some owners have reported issues with the diesel particulate filter (DPF) and the AdBlue system.

Legacy

The 3.0 V6 MultiJet engine has proven to be a relatively durable and reliable powertrain when properly maintained. In the used car market, these Grand Cherokees represent a good value proposition, offering a blend of luxury, capability, and fuel efficiency. However, potential buyers should be aware of the potential for DPF and AdBlue system issues and ensure that the vehicle has been regularly serviced. The 2017-2021 facelifted models, with their updated styling and improved features, are particularly desirable. The combination of the diesel engine and the 8-speed automatic transmission continues to be a popular choice among Grand Cherokee owners seeking a refined and capable SUV.
