Infiniti QX4 History

The QX4 (1997–2003) was Infiniti's original SUV, built on the Nissan Pathfinder WD21 and later R50 platform with premium accommodations. It was one of the first luxury mid-size SUVs on the market when it launched for 1997.

Criticized over its lifespan for cramped packaging relative to American full-size SUVs, the QX4 was discontinued after the 2003 model year and replaced in spirit by the larger QX56.
