INTRODUCTION
The 2017-2019 Jeep Grand Cherokee 3.0 V6 EcoDiesel 4×4 Automatic represented a significant offering within the WK2 generation. Positioned as a mid-range trim, it slotted between the base V6 gasoline engine and the high-performance SRT and Trackhawk models. The EcoDiesel engine was designed to provide a compelling alternative for buyers prioritizing fuel economy and towing capability without sacrificing the Grand Cherokee’s renowned off-road prowess. The facelift introduced in 2017 brought subtle styling updates, an upgraded infotainment system, and enhanced safety features, further solidifying the Grand Cherokee’s position as a competitive SUV.
Powertrain & Engine Architecture
The heart of this Grand Cherokee variant is the 3.0-liter V6 EcoDiesel engine, designated as the EXN engine code. This engine utilizes a third-generation 2.0-liter MultiJet II common-rail diesel injection system, delivering fuel at pressures up to 2,600 bar. The engine features a variable geometry turbocharger (VGT) with an intercooler to enhance performance and efficiency. The valvetrain employs dual overhead camshafts (DOHC) with four valves per cylinder. The eight-speed automatic transmission, sourced from ZF, is a crucial component of the powertrain. It provides smooth and efficient gear changes, contributing to both fuel economy and drivability. The transmission is programmed with specific shift points optimized for the diesel engine’s torque characteristics. A particulate filter is included as standard equipment to meet emissions regulations.
Driving Characteristics
The 3.0L EcoDiesel with the eight-speed automatic delivers a distinctly different driving experience compared to the gasoline-powered Grand Cherokees. While not as quick off the line as the V6 or V8 models, the EcoDiesel excels in providing strong, consistent torque from low engine speeds. This makes it particularly well-suited for towing and navigating challenging terrain. The eight-speed transmission helps keep the engine in its optimal power band, minimizing the need for frequent downshifts. The gear ratios are tuned for both fuel efficiency and responsiveness. Compared to a manual transmission, the automatic offers greater convenience, especially in everyday driving situations. However, some drivers may find the automatic less engaging than a manual gearbox. The EcoDiesel’s weight, combined with the automatic transmission, results in a slightly slower 0-60 mph time compared to the gasoline variants.
Equipment & Trim Levels
The 3.0 V6 EcoDiesel trim typically included standard features such as leather upholstery, dual-zone automatic climate control, a touchscreen infotainment system with Apple CarPlay and Android Auto compatibility, and a suite of safety features including blind-spot monitoring and rear cross-path detection. Optional extras included a panoramic sunroof, premium audio systems, advanced safety technologies like adaptive cruise control and lane departure warning, and various appearance packages. Interior color options varied depending on the year and specific package selected. The dashboard layout was consistent across the WK2 generation, with a focus on user-friendliness and intuitive controls.
Chassis & Braking
The Grand Cherokee’s chassis is designed to provide a comfortable ride and capable handling. The front suspension utilizes a coil spring, double wishbone setup with a transverse stabilizer bar. The rear suspension features an independent multi-link spring suspension, also with a stabilizer bar. Air suspension was available as an option, providing adjustable ride height and enhanced off-road capability. Braking duties are handled by ventilated discs on all four wheels, with front discs measuring 350×32 mm and rear discs measuring 330×22 mm. An anti-lock braking system (ABS) is standard. The braking system is tuned to provide confident stopping power, even when towing or carrying a full load.
Market Reception & Comparison
The 3.0 V6 EcoDiesel Grand Cherokee received generally positive reviews from automotive critics. It was praised for its fuel efficiency, strong towing capacity, and refined driving experience. Compared to the gasoline-powered Grand Cherokees, the EcoDiesel offered significantly better fuel economy, particularly on highway drives. However, the diesel engine carried a higher initial cost. Compared to other diesel SUVs in its class, the Grand Cherokee EcoDiesel offered a compelling combination of luxury, capability, and fuel efficiency. Some critics noted that the diesel engine was slightly noisier than the gasoline engines, but this was generally considered a minor drawback.
Legacy
The 3.0L EcoDiesel engine in the WK2 Grand Cherokee has proven to be a relatively reliable powertrain, although some early models experienced issues with the diesel particulate filter (DPF) and emissions control systems. These issues were largely addressed through software updates and revised components. On the used car market, the 3.0 V6 EcoDiesel Grand Cherokee remains a popular choice for buyers seeking a capable and fuel-efficient SUV. Its strong resale value reflects its reputation for reliability and its desirable combination of features. Proper maintenance, including regular oil changes and DPF servicing, is crucial for ensuring the long-term health of this powertrain.
