SRO Motorsports Group (formerly the Stéphane Ratel Organisation) is an international sporting organisation best known for promoting and running a variety of racing events and series, including the CrowdStrike 24 Hours of Spa, Intercontinental GT Challenge and Fanatec GT World Challenge Europe.

[1] SRO also organises the multi-disciplinary FIA Motorsport Games, as well as e-sports events and touring car categories.

The series is aimed at manufacturers, though rather than field their own cars they are encouraged to appoint and support local teams in selected events.

Fanatec GT World Challenge was launched in 2019 by uniting SRO's established continental series in Europe, Asia and America.

Originally the GT Sports Club are contested with GT3-spec, RACB G3, GTE-spec and Trophy cars but during the COVID-19 induced hiatus it was re-organised for the new GT2 regulations and changed the name to GT2 European Series.

[7] The 2021 season is set to consist of seven domestic events and an overseas rounds at Spa-Francorchamps, as well as a revised class structure.
