2005 Infiniti QX56 Review

Incredibly stylish, luxurious, and capable of smooth handling but is plagued with low fuel economy.

Reviewed by Automotive on


The wide variety of choices in the sport utility vehicle (SUV) category has been slowly shifting and changing over the past years. Buyers of traditional SUVs tend to be people who required towing power as well as the ability to maneuver off-road with ease. However, the unique design matched with the expanded options for seating space has made the SUV a popular choice for larger families who just want to get around urban areas in high class style. Both potential audiences have been closely targeted by multiple car manufacturers with SUVs made just for those two different sets of needs. The issue comes along when someone wants the best of both: the combination of the off-road driving power of a pure performance-based SUV's matched specifically with the ability to embrace luxury while on the standard paved streets of urban areas can be a bit difficult to find.

Enter the 2005 Infiniti QX56; based off of foundational platforms, which made several other popular traditional SUVs, it has been able to embrace stout off-road power and is extremely strong in terms of towing capacity. These qualities are then matched with the Infiniti philosophy of luxurious cabin interiors and sleek exterior looks. The final result is a stylish, full-size SUV that can easily drive in a variety of settings while still maintaining a very stylish appearance and plenty of fun and useful standard features.

The Range

Engines: 5.6-liter V-8
Transmissions: five-speed automatic
Models: 2005 Infiniti QX56 Base

What's New

Since the QX56 was only released on the market in 2004, the brand new vehicle is still working its way into the garages of the average driver. To make sure that the QX56 can have enough to grow in popularity, the 2005 model carried over without any significant changes. The only alterations are the additions of a rearview monitor and active head restraints for front occupants.


One of the standard selling points of the 2005 Infiniti QX56 is its very stylish exterior. It is a very smooth-looking SUV with plenty of clean lines, favoring a slightly swept-back appearance with a strong rectangular structure rather than the recently popularized total box shape. The headlights are housed in rectangular wraparound moldings to support the luxurious style of the exterior. The bright horizontal grille bars are flanked by the lights, which are actually xenon high-intensity-discharge. The taillamps get the added perk of being composed of LED lights. Standard exterior features for the QX56 include a roof rack, running boards, powered flip-out rear quarter windows, and a powered rear liftgate. All of these traits help support the vehicle’s luxury and functionality.


The 2005 QX56’s interior has been amazingly styled. Sojourner leather-appointed upholstery comes standard. The genuine wood trim comes in either Dark Macore or Blonde Apaya with the steering wheel outfitted in a combined wood and aluminum trim to match. Depending on how the second-row seats are laid out, the vehicle can sit seven or eight occupants. The second row is truly one of the greatest attributes of the cabin. The captain's chairs of the second row have integrated armrests and are placed around a removable second-row center console. A folding bench seat can be substituted for these chairs if one additional seat is needed. Finally, a fold-flat bench seat composes the seating option of the third row. Front seats and second-row seats are heated. The QX56 is tech-savvy as well. The 10-speaker Bose audio system includes a six-CD changer. The navigation system utilizes a seven-inch screen. The optional DVD Family Entertainment System comes with two pairs of wireless headphones.

Performance & Handling

The 2005 Infiniti QX56 is powered by a 5.6-liter Endurance V-8 engine, which can produce 315 horsepower and an impressive 390 lb-feet of torque. The only available transmission is the five-speed automatic though, but this gearbox incorporates a Tow/Haul mode. The QX56 can be equipped with either four-wheel drive or rear drive.


Infiniti has a very high reputation for safety. The 2005 QX56 comes well stocked with standard safety equipment, including all-disc anti-lock brakes with electronic brake-force distribution, brake assist, a tire-pressure monitoring system, and a Vehicle Dynamic Control electronic stability system. In terms of airbags, the QX56 features seat-mounted side-impact airbags and side curtain airbags for all three rows of seats.
