The QX56 is part of the Infiniti QX family, a line of SUV from Nissan's luxury division. This full-size SUV made its debut as a 2004 model. The earlier generation of the QX56 didn't have as much cargo capacity and luxurious interior. Fortunately, in the redesign for the succeeding generation, Infiniti made sure that these deficiencies were addressed. The newer and better Infiniti QX56 gave other full-size luxury SUVs a run for their money. Equipped with a powerful V8 engine, it was highly rated for its excellent towing capabilities. It was designed with a spacious and comfortable cabin and was equipped with a good number of high-end features. The QX56 was conceived with urban recreation and towing in mind, more than off-roading. This brawny full-size SUV could survive most weathers and provide luxury in travel.
2004-2010: The earlier generation of the QX56
The QX56 was the first Infiniti model to be manufactured in the United States. This Infiniti SUV could seat up to seven passengers and was based on the Nissan Armada design. It had the same F-Alpha platform as the Nissan Titan pickup track. The chassis and other mechanical works were the same with the Nissan Armada and Titan. The earlier QX56 was powered by a 5.6L V8 engine that could churn out up to 320 hp and 393 lb.-ft. of torque, which was then mated to a five-speed automatic transmission. Rear-wheel and four-wheel drive options were available for the previous generation.
There were just a few changes made on the Infiniti QX56, including the 60/40 split for third-row seating. It also came with a Bluetooth hands-free system and had better exterior mirrors for the 2006 model. The earlier QX56 could tow up to 9,000 pounds, but it came up a little short when pitted against the Cadillac Escalade and other more luxurious SUVs. The plastic trim felt a bit cheap. Fortunately, the interior was redesigned for 2008 to position it a notch higher as a more luxurious SUV. Better materials and a new instrument cluster design were used. There were more standard features in the vehicle, and it upgraded its audio and navigation systems. The SUV's front and rear ends were revamped, along with other styling cues and performance features.
2010-2014: The new and improved Infiniti QX56
The newer generation QX56 was unveiled in 2010 at the New York International Auto Show. It was more of a luxury version of the Nissan Patrol and was equipped with a 5.6L VK56VD V8 engine that could generate more power--up to 400 hp and 413 lb.-ft. of torque. It was mated to a seven-speed automatic transmission. This resulted in improved off-roading capacity, towing ability, and fuel economy. It handled better, and it was more refined with standard features and equipment such as the tri-zone automatic control, top-view camera system, and 13-speaker Bose audio system. The newer QX56 had a change in appearance as well. It looked like it belonged to the pack of other large luxury SUVs such as the Cadillac Escalade, Range Rover, and Lexus LX.
Not much had changed for the 2013 Infiniti QX56 model. It was simply designed with a moving obstacle identification technology, found in side-view and rear cameras. For the 2014 model, the QX56 was rebadged as the QX80.
