When did they stop making Infiniti QX56?
The Infiniti QX56 was discontinued after the 2013 model year, and starting with the 2014 model year the model was renamed to QX80; the QX56 name is no longer produced.
Background: what happened to the QX56?
The QX56 was Infiniti’s full-size luxury SUV designed to offer three-row seating, strong V8 power, and a premium interior. It existed in two generations over its lifecycle, and in the early 2010s Infiniti began a broader renaming strategy for its lineup. This shift culminated in retiring the QX56 name and introducing the QX80 as its successor.
Timeline of the QX56 and its transition
Here are the key milestones in the model’s lifecycle:
- 2004: Infiniti launches the QX56 as its flagship full-size SUV.
- 2013: Infiniti retires the QX56 name and announces the transition to the QX80 for the 2014 model year.
- 2014 onward: The QX80 becomes Infiniti’s large SUV, continuing the lineage under a new name.
The move to the QX80 reflects Infiniti’s broader naming strategy, aimed at creating a consistent family of "QX" models with uniform branding across its lineup. The QX80 remains the current large SUV in production, while the QX56 badge is no longer used.
Why the rename?
Automakers periodically refresh model names to align with marketing strategies and model lineups. Infiniti’s shift to the QX80 was part of a broader effort to standardize its SUV naming conventions, improve brand clarity, and unify the product family under a common QX prefix.
Current status and context today
As of today, the Infiniti QX80 remains in production and serves as the direct successor to the QX56. Buyers seeking a large luxury SUV from Infiniti should look for the QX80 in model years from 2014 onward. If you’re researching used vehicles, QX56 units are limited to the 2004–2013 production window and are now part of automotive history rather than a current model.
Summary
The QX56 was discontinued after the 2013 model year and replaced by the QX80 for the 2014 model year. Infiniti’s naming consolidation moved the family toward a single QX designation, with the QX80 continuing to serve as the brand’s flagship large SUV. The QX56 badge is no longer in use, and the current large Infiniti option remains the QX80.
