The Infiniti G-series is a line of compact executive/entry-level luxury car that was produced by the Infiniti division of Nissan for the 1990–1996 and 1998–2013 model years. The first two generations of the Infiniti G (P10 and P11) were sedans based on the Nissan Primera. Beginning with its third generation (V35), the Infiniti G have been rebadged versions of the Nissan Skyline line of sedans and coupes that were exported to the United States and Canada. The current incarnation is the fourth generation (V36) which introduced the hardtop coupe convertible. The Nissan FM platform, on top of which the third and fourth generations (V35 and V36) of the Infiniti G have been built, also underpins the Nissan 370Z and has shared components with the Infiniti M, Infiniti EX, and Infiniti FX.
It was announced that the Infiniti G will be renamed the Infiniti Q50 4-door large family car in 2013, but decided to continue selling both the Q50 and G37 so as to introduce their new naming convention to consumers. The new naming convention was introduced May 2013.
