The Jeep Grand Cherokee WG, produced from 2003 to 2004, marked a significant shift in the model's history. Following the success of the WJ generation, the WG introduced subtle refinements and updates, aimed at enhancing both performance and refinement. While retaining the robust and capable foundation of its predecessors, the WG Grand Cherokee showcased a more modern and sophisticated demeanor. This was evident in the updated exterior styling, featuring a redesigned front fascia with a new grille and headlights, along with revised taillights and a more streamlined rear end. The interior received a refresh as well, with upgraded materials, revised instrument panel, and improved ergonomics. Under the hood, the WG Grand Cherokee offered a range of engines, including the 4.7-liter PowerTech V8, the 4.0-liter inline-six, and the 5.7-liter Hemi V8. While the PowerTech V8 offered a balance of power and fuel efficiency, the Hemi V8 delivered impressive performance, with increased horsepower and torque compared to its predecessor. Both engine options were paired with a four-speed automatic transmission, providing smooth and responsive gear changes. The WG Grand Cherokee continued to offer a capable four-wheel-drive system, ensuring off-road capability and enhanced traction in challenging conditions. However, the platform's emphasis on refinement also extended to its on-road performance, with a more comfortable ride and improved handling characteristics. The 2003-2004 Jeep Grand Cherokee WG, with its refined design, powerful engine options, and enhanced capabilities, established itself as a compelling choice in the mid-size SUV segment, combining ruggedness with a touch of sophistication.
