The 2002 Infiniti QX4 is a mid-size luxury SUV that was produced by Nissan and marketed under the Infiniti brand. It was the second generation of the QX4, following the first generation which ran from 1997 to 2001. The QX4 was based on the Nissan Pathfinder platform and shared its underpinnings with the Nissan Xterra, providing a rugged and capable foundation. The 2002 model year saw a significant redesign, introducing a more modern and sophisticated aesthetic. It featured updated styling with a larger grille, new headlights, and a more streamlined body. Inside, the QX4 offered a well-appointed cabin with leather upholstery, wood trim, and generous passenger space for five occupants. It also came equipped with several standard features, including power windows, locks, mirrors, and a premium sound system. Under the hood, the 2002 QX4 was powered by a 3.3-liter V6 engine producing 170 horsepower and 198 lb-ft of torque. This engine was paired with a 4-speed automatic transmission and a part-time four-wheel-drive system, allowing for capable off-road performance. The QX4 offered a comfortable and refined ride, thanks to its independent suspension system and well-tuned steering. Its spacious interior and versatile cargo area made it a suitable choice for families and outdoor enthusiasts alike. Despite its rugged capabilities, the QX4 provided a comfortable and sophisticated driving experience. However, its fuel efficiency was not its strong point, and its off-road prowess was surpassed by some of its rivals. While the 2002 Infiniti QX4 was a solid offering in the mid-size SUV segment, its lack of innovation and dated technology ultimately led to its discontinuation in 2004.
