The 2002-2003 Jeep Grand Cherokee, encompassing the WJ and WG models, represents a pivotal era for the iconic SUV. While retaining the rugged charm and off-road capability that defined the Grand Cherokee lineage, these years saw significant refinements and updates. Notably, the WJ series, introduced in 1999, was in its final stages, while the WG series marked the debut of the redesigned Grand Cherokee, ushering in a new chapter for the model. The 2002-2003 model years offered a diverse powertrain lineup, including the venerable 4.0-liter inline-six engine, the powerful 4.7-liter V8, and the high-performance 5.7-liter V8. These engines were paired with either a four-speed automatic or a five-speed automatic transmission, depending on the engine and trim level. The Grand Cherokee's renowned off-road prowess was further enhanced by the availability of the Quadra-Drive and Quadra-Trac II four-wheel drive systems, providing exceptional traction and stability on challenging terrain. The 2002-2003 Grand Cherokee models also incorporated several significant comfort and convenience features, including a spacious and well-appointed interior, a comprehensive suite of safety systems, and an array of optional technologies. The interior featured comfortable seating for five occupants, ample cargo space, and a user-friendly dashboard layout. Safety features included dual front airbags, side-impact airbags, and anti-lock brakes. Optionally, the Grand Cherokee could be equipped with features such as a sunroof, power seats, a premium sound system, and a navigation system. These additions aimed to elevate the Grand Cherokee's appeal beyond its rugged capabilities, making it a compelling choice for both on-road and off-road driving. The 2002-2003 Jeep Grand Cherokee, in its WJ and WG iterations, continued the legacy of a capable and versatile SUV, offering a blend of strength, comfort, and refinement that made it a popular choice for a wide range of drivers.
