The world's only global GT3 series represents the highest echelon of long-distance GT racing, while its 2020 calendar once again features five iconic circuits on as many continents.

Established in 2016, the series’ purpose couldn’t be simpler: reward the manufacturer and drivers who achieve the best collective results in the world’s greatest standalone endurance events.

The proliferation of GT3, built on a decade of manufacturer involvement and SRO’s Balance of Performance stability, has resulted in it becoming the de facto senior class for all of the world’s most prestigious GT races.

This, as well as using the same Pirelli tyres, offers manufacturers an incentive to compete in all such events by employing regional customer teams without the expense of freighting cars around the world.
 
The season begins in February with Australia's international enduro - the Liqui-Moly Bathurst 12 Hour - before moving on to Europe for the world's biggest GT3 event in late July: the Total 24 Hours of Spa.

It's followed one month later by the Suzuka 10 Hours, which takes place at the iconic figure-of-eight circuit in Japan. The world-famous Brickyard then hosts the inaugural Indianapolis 8 Hour in early October before the Kyalami 9 Hour closes out the campiagn in Africa.
