The Infiniti QX4 is a mid-size luxury SUV manufactured by Infiniti, the luxury division of Nissan, and introduced in September 1996. Infiniti based the QX4 on the unibody Nissan Pathfinder and was released to compete with the Acura SLX and Lexus LX 450. The model was also Infiniti's first entry into the SUV market category.

History of Infiniti QX4

Infiniti QX4 (1997 - 2001)

With the release of the QX4 model in 1997, Infiniti began its breakthrough into the off-road category with a rebadged variant of the Nissan Pathfinder. Infiniti was the only Japanese luxury manufacturer that didn't have an SUV in its portfolio after Acura and Lexus released the SLX and LX450, respectively, in 1995. Nissan's second-generation Pathfinder was released in 1995 and was widely regarded as an excellent starting moment. The QX4 has a unique front fascia while sharing many body parts with the Pathfinder.

Infiniti QX4 (1997 - 2003)

In 2000, Infiniti refreshed its QX40 entry-level SUV with a new design. Nissan wanted a piece of the luxury market, so it launched the Infiniti brand with cars based on Nissan vehicles. The Nissan Terrano served as the QX4's base, and Infiniti only offered it as a four-door model. Even though it was smaller and lighter than a typical SUV because of its unit-body design, the Nissan's standard robust drivetrain allowed it to perform admirably in off-road conditions. The FX35/45 crossover SUV replaced the QX4 when discontinued in 2003. Infiniti manufactured the last QX4 in November 2002. In 2004, the QX4 was replaced by the bigger QX56.


Infiniti sold the 2003 Infiniti QX4 with an MSRP from $34,750 to $36,150 ($53,582 to $55,740 in 2022).


A new exterior color, Diamond Graphite, and optional chrome-finished aluminum-alloy wheels elevate the QX4's sophisticated design for the 2003 model year. High-intensity discharge (HID) xenon headlights with automatic on/off function, incorporated fog lights, and signal lights are standard on the Infiniti QX4. Other exterior features are 17-inch aluminum-alloy wheels, a full-size spare tire & alloy wheel, black privacy glass, dual body-color power remote-controlled heated outside mirrors, splash guards, variable intermittent rear liftgate glass wiper, and step rails with slip-resistant inserts. Infiniti was determined to create a luxurious and comfortable interior. The QX40 included leather seats, wood trim, and a good sound system. Infiniti also included the sunroof and the navigation system as standard equipment.

  • Leather-appointed seats

The Infiniti QX4 engine delivers 243 hp (179 kW) at 6,000 rpm and 265 lb-ft (359 Nm) at 3,200 rpm of torque. The Infiniti QX4 accelerates from 0 to 60 mph (97 kph) in 9.1 seconds with a top speed of 110 mph (177 kph) and a curb weight of 4,352 lbs (1,974 kg). Infiniti sold the QX4 as a rear-wheel-drive (FWD) vehicle with a 4-speed automatic gearbox powered by a DOHC 24-valve V6 engine.
