From Infiniti press: Since its ground-breaking introduction in 1997, the Infiniti QX4 luxury sport utility vehicle (LSUV) has become one of the most appealing nameplates in its class. Boasting a distinctive combination of style, strength and technology, including the exceptional performance of its advanced All-Mode 4WD® system, the QX4 offers true off-road capability in unabashed comfort.
QX4 sales have surpassed all projections, with more than 28,000 QX4s hitting the road since its launch. The QX4 was also ranked by its owners, for two years running, as the “Best Compact Sport Utility” in the J.D. Power and Associates Initial Quality Study (IQS) - validating Infiniti’s uncompromising commitment to quality and customer satisfaction.
To provide a stable platform, reduced noise and vibration, improved ride and handling and excellent body fit, the QX4 is built with rigid MonoFrame® construction. This technique draws from both unibody automotive design and body-on-frame truck design to produce a hybrid that combines the best elements of both.
The 1999 QX4 is powered by a refined 3.3-liter SOHC 12-valve V6 engine that produces 168- horsepower at 4,800 rpm and 196 ft-lbs of torque at 2,800 rpm. Over 90 percent of the engine’s torque is available in the 1,500 - 1,800 rpm range - providing exceptional power for low speed off-road driving and sustaining power at higher engine speeds for throttle response while accelerating, towing or cruising over long distances. All QX4s are equipped with a standard electronically controlled 4-speed automatic transmission mated to the advanced All-Mode 4WD system.
