Infiniti QX80

Z62 development began in 2006 following the concurrent Y62 program (since 2003), after Nissan management voted to move QX56 production back to Japan and separate from the Nissan Armada, after the JA60's production run concluded. By 2007, a styling proposal by Shinya Momokawa and Akihiro Sugita was approved by the board and frozen for production. In September 2009, spy photography of a 2011 QX56 (Z62) prototype, at a Las Vegas Infiniti national dealer conference, were published online.

2012 Infiniti QX56 (US)

On 31 March 2010, Infiniti debuted the 2011 QX56 at the New York International Auto Show. No longer sharing a platform with the F-Alpha-based Nissan Armada, the QX56 was now a luxury version of the Nissan Patrol, which also marked the first time that a Patrol-based vehicle had been sold in North America since 1969. The QX56 features a new 5.6L VK56VD V8 engine with direct injection and VVEL variable valve timing, also found in the Nissan Patrol, which is rated at 400 hp (298 kW) and 413 lb·ft (560 N·m) of torque. The more powerful engine helps give the QX an increased towing capacity of up to 8,500 lb (3,856 kg). The engine is tied to a seven-speed sequential-shift automatic transmission with an all-new 4WD system.

Compared to its predecessor, the new QX is 1.4 inches longer, 1.1 inches wider. Most of the frame's body mass is made from high-tensile steel, but the QX manages to be more rugged with its body-on-frame concept and it shares the same platform as the Nissan Patrol. Both the front and rear feature independent suspension double wishbone suspensions combined with the new Hydraulic Body Motion Control System. The QX comes standard with 20-inch wheels with 22-inch wheels available. 4WD versions have a four-setting terrain control which include rock, snow, sand and dirt modes. This generation abandoned the disguised rear door handles that were installed in the "C" pillar, a tradition started with the 1985 Nissan Pathfinder five-door, as the first generation QX was based on the second generation Pathfinder. This generation's appearance is more in line with other large luxury SUVs like the Mercedes-Benz GL-Class, Lexus LX, Land Rover Range Rover, Cadillac Escalade, and Lincoln Navigator.

The QX's interior design includes a number of the standard and optional luxury features in the 2010 Infiniti M, such as semi-aniline leather seats, tri-zone climate control, a Bose 2-channel, 13-speaker Premium Audio surround sound stereo system with hard drive memory storage, hard-drive based navigation system, XM satellite radio with NavTraffic is standard, a power liftgate/tailgate, and Infiniti Intuitive Park Assist, a parking assist feature which uses the around view monitor. Other features include climate-controlled front and rear seats, streaming audio via Bluetooth wireless technology, a center console, power sliding rear seats, power third row seats, and a 7-inch DVD rear-seat entertainment system. Curtain Vent, new for this generation, directs air flow from the air conditioning system from above each side window down towards the floor. A new Around View Monitor system uses a camera mounted on the grill, giving a 180-degree view in front, and another camera mounted on the passenger side of the vehicle's side mirror helps eliminate blind spots on the side at low speeds, such as when in parking lots or on off-road adventures.

The QX also features the updated Infiniti hard drive based navigation system with an eight-inch VGA display. Infiniti keyless SmartAccess with an "Intelligent Remote" key is standard along with 8 airbags including knee airbags for driver and front passenger as well as second-row side torso airbags, the Adaptive Front-lighting System (AFS) is standard, while the Pre-Collision System (PCS),Vehicle Dynamic Control (Electronic stability control) systems and lane departure warning system are available options.

Infiniti QX80

In 2013 for the 2014 model year, Infiniti renamed their entire product line, so the QX56 was rebadged as the QX80 in April 2014. Coinciding with the renaming, the QX80 arrived at the New York International Auto Show with a mid-generational refresh, receiving new headlights and taillights with new front and rear fascias, restyled bi-xenon HID projector headlamps with LED daytime running lights, front LED turn signals (located on front bumper with new LED fog lights), new wheel designs (including a new 22-inch forged-aluminum version), three new exterior colors, and a number of interior refinements for the 2015 model year. The new flagship trim level for 2015 is the QX80 Limited which features all the QX80 packages and optional equipment that is available on other QX80 trim levels, while its standard on the new QX80 Limited trim level, standard Intelligent All Wheel Drive (AWD), and restyled LED clear lens taillights instead of the LED red lens taillights, however the QX80 Limited trim level is not available with the second row bench seating which increases the passenger capability from 7 seats to 8 seats. It will still be offered with the same 5.6-liter VK56VD V8 engine. Naoyuki Ohkoshi was responsible for exterior design work on the facelift QX80 in 2012.

As of 2017, the Infiniti QX80 is available in the United States (including all US territories), Canada, Mexico, China (including Macau and Hong Kong, excluding Taiwan), the GCC markets, Russia, Ukraine, Azerbaijan, South Korea, Dominican Republic, Guam, Panama, Australia, Malaysia, Singapore and Vietnam. An RHD version became in some markets as part of the facelift in late 2014.

In late 2016, the 2017 Nissan Armada was released and it switched from the F-Alpha to the Nissan Patrol platform, so the Armada is once again a mechanical twin of the QX80 (formerly QX56) since the 2010 model years. It has been noted that the top trims of the Armada and QX80 have nearly identical interiors despite the MSRP differential; $61,435 for Armada Platinum versus $89,845 for a fully equipped QX80.[5][6][7]
