In 1997, Infiniti made its first significant push into the off-road and luxury SUV market with the debut of the QX4, a refined and rebranded version of the Nissan Pathfinder. This launch arrived as the luxury SUV trend was accelerating, with Acura and Lexus already having entered the space with the SLX and LX450, respectively. Infiniti had been the only Japanese luxury brand without a sport utility vehicle, and the second-generation Pathfinder - introduced in 1995 with a more modern unibody design - offered the perfect foundation for its inaugural SUV.
The QX4 maintained the rugged underpinnings and structure of the Pathfinder but introduced distinctive luxury and design elements. The front fascia featured a bold horizontal grille bar, new headlamp housings with corner-mounted turn signals, and additional fog lights that added to its upscale presence. Stationary driving lamps contributed to a sophisticated look, while side steps enhanced daily usability. At the rear, rather than affixing the spare wheel to the tailgate, it was tucked neatly beneath the floor, giving the QX4 a cleaner and more premium silhouette.
In 2000, Infiniti gave the QX4 a mid-cycle refresh to keep it competitive in the growing segment. The facelift brought a reimagined front end that incorporated the Infiniti badge more prominently, redesigned headlight clusters with integrated turn signals, and upgraded fog light housings within the bumper’s side scoops. The rear styling was updated as well, featuring new taillights and a reworked bumper to give the QX4 a more refined yet functional finish. Known internally as part of the QX40 series, the refreshed version retained its unibody construction - making it lighter and more car-like to drive than many body-on-frame competitors - yet it remained capable in moderate off-road conditions.
Infiniti’s ambition to expand further into the SUV market culminated with the introduction of the QX56 in 2004, its first entry into the full-size luxury SUV segment. Built on the F-Alpha platform shared with the Nissan Titan pickup and Armada SUV, the QX56 was Infiniti’s response to the Cadillac Escalade, Lincoln Navigator, and the Lexus LX470. The full-size SUV market demanded presence and capability, and Infiniti responded with a vehicle that combined bold styling with premium appointments.
The second-generation QX56, unveiled at the 2010 New York Auto Show and launched for the 2011 model year, was a major leap forward in both engineering and design. Unlike its predecessor, this model was no longer based on the Armada but instead on the international Nissan Patrol Y62, a revered name in global off-roading circles. The QX56 retained Patrol's rugged architecture while introducing a new level of sophistication. Its large chrome grille, dramatic headlight clusters, and upright, muscular proportions projected confidence and luxury. A power liftgate and distinctive rear profile signaled its premium status.
Inside, the QX56 was equally impressive. The cabin featured soft-touch materials, plush leather upholstery, and real wood trim across the dashboard, center stack, and door panels. Seating for seven or eight was available, with captain’s chairs often selected for second-row passengers. The interior layout prioritized both driver ergonomics and rear passenger comfort. Though the infotainment system lacked touch capability, it offered a robust suite of features and was easily navigable through tactile controls placed beneath the screen.
