(August 3, 2022) MIAMI — As the biggest vehicle in the company’s fleet, the 2022 Infiniti QX80 serves as Infiniti’s flagship SUV and has done so since debuting as the QX56 in 2004. The name change came for 2014 when Infiniti abandoned the practice of using the numbers in its alpha-numeric nomenclature to designate engine size. The QX56, for example, came with a 5.6-liter V8 engine. The new system instead reflected the vehicle’s place in Infiniti’s portfolio. The higher number, the higher the vehicle’s place in the hierarchy.
