The Fédération Internationale de l’Automobile, or FIA, supported Gran Turismo Sport’s competitive online racing.
Polyphony Digital and the FIA developed the FIA-certified Gran Turismo Championships around Gran Turismo Sport. The partnership gave the game’s online competition an official motorsport framework rather than treating it as an ordinary leaderboard or informal esports league. The FIA also helped lend sporting credibility to the championship structure.
The competition centered on two parallel series: the Nations Cup, where drivers represented their countries, and the Manufacturers Series, later known as the Manufacturers Cup, where competitors raced for automobile brands. Successful players advanced through regional and world-level events, with champions recognized at FIA prize-giving ceremonies.
The other options are real motorsport organizations, but they are not the body associated with this Gran Turismo Sport championship. ACO is linked especially with the 24 Hours of Le Mans, NASCAR governs major stock-car racing in the United States, and IMSA sanctions North American sports-car competition. The FIA is the broad international governing body that supported this specific online series.
