The Infiniti QX80 (called the Infiniti QX56 until 2013) is a full - size luxury SUV built by Nissan Motor Company 's Infiniti division. The naming convention originally adhered to the current trend of using a numeric designation derived from the engine 's displacement, thus QX56 since the car has a 5.6 - liter engine. From the 2014 model year, the car was renamed the QX80, as part of Infiniti 's model name rebranding. The new name carries no meaning beyond suggesting that the vehicle is larger than smaller models such as the QX60.
