About SRO

Since 1995 SRO has specialised in the promotion and organisation of motorsport series. Inextricably linked with GT racing’s revival, SRO predominantly promotes categories that adhere to its successful GT3 and GT4 regulations. Indeed, these rules - a common framework allowing manufacturers, teams and drivers to compete equally with one another - has helped establish SRO as the global leader in customer GT racing.

Today, SRO’s influence and organisation can be seen around the world. SRO's flagship is the European-based Blancpain GT Series, which combines the Sprint and Endurance Cups, of which the iconic Total 24 Hours is the highlight.

The same regulations and Balance of Performance parameters governing the Blancpain GT Series have been adopted in the United States by the Pirelli World Challenge (in which SRO is also a major shareholder), while the inaugural Blancpain GT Series Asia has been successfully launched in 2017.

In addition, the world’s greatest GT3 races from all four corners of the globe are brought together under the umbrella of the Intercontinental GT Challenge, which includes the LiquiMoly Bathurst 12 Hour, Motul Sepang 12 Hours, Total 24 Hours of Spa, as well as the new high-profile California 8 Hours. Amateur drivers are also fully catered for via the Blancpain GT Sports Club.

Likewise, select European race weekends feature the GT1 Ultracar Sports Club where the world’s fastest and most technologically advanced limited-production road and track-only cars gather to demonstrate their awesome capabilities. This very exclusive series also includes the finest racers to have ever graced the world GT championships’ premier category from 1994 to 2011.

SRO is also strong domestically. The multi-class British GT Championship, which it has presided over since 2005, pairs GT3 with GT4 machinery, while France’s national series - now known as the GT4 European Series Southern Cup / FFSA French GT championship – has been added to its existing Northern Cup counterpart.

SRO also operates the SRO Race Centre by MMC - a high-level technical centre at Paul Ricard Circuit in southern France - and Curbstone Track Events, which provides ultimate track driving opportunities on Europe’s most iconic circuits.

SRO Motorsports Group is chaired by company founder and CEO Stephane Ratel and has offices in London, Paris, Hong Kong and Liège.
