The series is aimed at manufacturers. Instead of fielding their own cars, manufacturers support local teams in selected events to gain points. Four manufacturers took part in the inaugural series in
2016:
Audi,
Bentley,
McLaren and
Mercedes. The races may be stand-alone events, like the
Suzuka 1000km and the
Bathurst 12 Hour, or part of another championship, like the
24 Hours of Spa and
Indianapolis 8 Hour, but they are all contested by cars complying with the same technical regulations. ==Champions==
