The Infiniti QX4 and the Nissan Terrano Regulus are mid-size luxury SUVs introduced in 1997 as rebadged Nissan Pathfinders. It was released a year after Acura's release of the SLX and Lexus's release of the larger LX 450, and it is Infiniti's first entry into SUVs. The Infiniti QX4 was sold in the North American market, while the Nissan Terrano Regulus sold in Japan. Major differences between these vehicles and the Pathfinder include a more advanced four wheel drive system, a more upscale interior, and unique styling. Although it is a luxury vehicle, it is quite capable off-road due to its low range four wheel drive system and 8.3 inches of ground clearance.

The QX4 received its first major update in 2001, with a new engine increasing its power from a relatively weak 168 hp (125 kW) to a comparative 240 hp (179 kW) engine. The displacement went from 3.3L to 3.5L. The timing belt was replaced with a timing chain, and the more reliable ignition distributor was replaced with a problematic individual coil ignition system.

This 2001 facelift also gave the QX4 an updated exterior and interior body style, including features such as a new dash with integrated clock, 17 in (423 mm) alloy wheels and xenon HID headlamps. In Japan, the Terrano Regulus shortened its name to Terrano and was restyled like the Pathfinder instead.

The QX4 was discontinued in 2003, and its position in price would be taken by the G35/M35/M45-based FX35/45 crossover SUV.
