In 2000, Infiniti introduced a mid-life cycle refresh for its entry-level SUV, the QX40.
Nissan was determined to get a slice of the premium-segment and introduced the Infiniti brand with vehicles based on the regular Nissan models. The QX4 was based on the Nissan Terrano, and it was available with four-doors only. Its unit-body construction made it lighter than a regular SUV, but nevertheless was good in off-road use thanks to its standard, rugged Nissan drivetrain.
From the outside, the 2001 QX4 sported a new front fascia with the Infiniti logo on it. The lower part of the bumper featured new fog lights installed on the outer side scoops. Its headlights were redesigned and incorporated the turn-signals on their outer side. In the rear, the QX40 featured new taillights and a modified bumper design.
Inside, Infiniti insisted on creating a comfortable and premium interior. The leather seats and wood-trims were a must for the QX40, and so was the sound system. On the other hand, some features were fitted as an option, such as the sunroof or the navigation system. Unfortunately, Infiniti couldn't resolve a problem mentioned on the Nissan Terrano: the QX40 carried over the lack of adequate rear legroom.
A big improvement for the facelifted version was the VQ35 engine that offered 243 hp. It was paired as standard to a four-speed automatic transmission.
