Infiniti QX4 1997-2003

The Infiniti QX4, produced from 1997 to 2003, was a mid-size luxury SUV that aimed to blend off-road capability with premium features. Based on the Nissan Pathfinder, it featured a robust body-on-frame construction that made it suitable for both on-road and off-road adventures. The QX4 boasted a refined and comfortable interior with leather upholstery, wood accents, and a range of high-end amenities, including a Bose sound system and a power moonroof. Its rear-wheel-drive and four-wheel-drive variants and features like a limited-slip differential and multi-mode four-wheel-drive system made it versatile for various driving conditions.

Under the hood, the QX4 typically had a V6 engine paired with a smooth-shifting automatic transmission. While it wasn't known for its fuel efficiency, it provided adequate power for highway cruising and light off-roading. The QX4 earned praise for its off-road capability, thanks to features like a low-range transfer case, good ground clearance, and a rugged suspension. Overall, the Infiniti QX4 appealed to buyers looking for a luxury SUV to handle urban and outdoor adventures with style and comfort.
