Which Gran Turismo game was the first to feature officially FIA-certified content?

Gran Turismo 6 was the first Gran Turismo game to feature officially FIA-certified content.

The FIA partnership brought formal certification to selected Gran Turismo 6 material, linking the virtual racing series with the Fédération Internationale de l'Automobile. The certification was announced in 2014, after the game's December 2013 release, as part of a broader collaboration with Polyphony Digital.

This is commonly confused with Gran Turismo Sport, which later placed a much stronger emphasis on officially sanctioned online competition and became closely associated with FIA championships. However, Gran Turismo 6 came first in featuring FIA-certified content. It also introduced a large collection of new and updated cars, circuits, and online features during the PlayStation 3 era.
