2006 Infiniti QX56 Review

Competes well in a flooded market place.

Reviewed by Automotive on


Introduced in 2004, the Infiniti QX56 marks the first time Infiniti entered the luxury sport utility vehicle (SUV) market. The QX56 has the ""Q"" designation reserved for the top-of-the-line vehicles in Infiniti’s fleet.

The 2006 Infiniti QX56 shares a platform and design similar to that of the Nissan Armada. This design is a little odd for an SUV with its strange roof and side window design. The vehicle is also very heavy, weighing in at nearly 5600 pounds. The vehicle’s big V-8 is enough to move it along, which is a relief. The engine has a lot of torque, which gives the 2006 Infiniti QX56 incredible towing ability. It is capable of tugging along 9000 pounds, way more than what most other SUVs can pull, and more than what most drivers will ever require.

Although the exterior styling is interesting and the engine strong, the interior may be enough to turn some car buyers off. Although branded as a luxury SUV, the QX56’s interior materials do not reflect the ""luxury"" nomenclature. There is plenty of leather upholstery, wood trim, and other luxury features like heated front seats, but there is also a lot to dislike. The gauge cluster is somewhat cluttered and poorly designed, with a lot of hard plastics on the doors and dash.

However, the performance, towing capabilities, and roomy interior will be enough to convince many drivers that the 2006 Infiniti QX56 is the one for them.

The Range

Body Styles: Full-size luxury SUV
Engines: 5.6-liter V-8
Transmissions: five-speed automatic with auto-manual capability
Models: QX56

What's New

The 2006 Infiniti QX56 receives a new 60/40-split third row seat, standard Bluetooth hands-free connectivity, and power folding side mirrors.


The exterior styling of the 2006 Infiniti QX56 is interesting; unlike the curvy SUVs, the QX56 retains the old modified truck styling of older SUV models. The rear windows look like those you might find on a truck bed cover.

The 2006 Infiniti QX56 comes with standard 18-inch chrome wheels, HID headlights, and has an optional sunroof option.


The interior of the 2006 Infiniti QX56 is one of the few places this vehicle could use a bit of improvement. The seats are covered in leather, and the stitching is wonderful. There is thick carpeting on the floor that makes the interior feel a bit more like a living room than a car. The roomy interior will also give you a similar reaction, although hard plastic covers the dash and the doors.

Room is spacious, however. The second row has standard captain’s chairs that have a removable center console in the middle. The third row seat is a bench with a 60/40 split. Although the vehicle has plenty of legroom and headroom, cargo space is a bit less than your standard Escalade or Navigator model, with only 97 cubic feet of space. Space behind the third row, at 20 cubic feet, is a bit bigger than the competition.

Performance & Handling

The 2006 Infiniti QX56 is equipped with a 5.6-liter, V-8 engine that produces 315 horsepower with 390 lb-ft of torque. The engine is married to a five-speed automatic. The 2006 Infiniti QX56 is available in rear- or all-wheel drive.

Driving in the city, the 2006 Infiniti QX56 has an effortless feel. Acceleration is strong and clean, and gear changes with the automatic are as seamless as possible. The independent suspension keeps the QX56 from bouncing too much over large potholes and other debris. The handling is athletic for a luxury SUV, almost sport, and gives great satisfaction while taking corners. Even when towing, the QX56 rumbles to life. Not many luxury SUVs perform as well as the 2006 Infiniti QX56.


The QX56 is packed with safety features. Standard are side curtain airbags for all three rows, and seat-mounted side-impact airbags are available for the driver and front passenger as well. A parking sensor system for reversing the vehicle also comes standard, making it simple to park the QX56, even with a large load. All vehicles come with four-wheel disc anti-lock brakes, traction and stability control, a tire pressure monitor, and power adjusting pedals. The 2006 Infiniti QX56 received top marks for front impacts.
