Overview
The format changes slightly from year to year but in the 2007 event the participating drivers were grouped into eight two-person teams based on their nationality.
Prior to the Race of Champions itself these eight teams compete in the ROC Nations' Cup where a team advances by going head-to-head with another country's team and winning two races out of three. If each team wins one of the first two races, the winners of each round go head-to-head in the decider. The advancing team then goes through the semi-finals and super-finals, by which time only two teams remain.
In the main event – 'The Race of Champions' itself – the individuals compete head-to-head in one race around the track, with the winner advancing and the loser getting knocked out. Similar to the national race, the drivers are gradually eliminated until two reach the super-final.
In both the ROC Nations' Cup and the Race of Champions, the super-final consists of three runs. The team or driver that achieves two victories first wins.
