V8 Supercars is a touring car racing category based in Australia and run as an International Series under Fédération Internationale de l'Automobile (FIA) regulations.
V8 Supercar events take place in all Australian states and territories, excluding the Australian Capital Territory (which formerly held the Canberra 400). An overseas round is also held in New Zealand, with events previously held in China, Bahrain, the United Arab Emirates and the United States. A non-championship event is also held in support of the Australian Grand Prix. Race formats vary between each event with sprint races between 100 and 200 kilometres in length, street races between 125 and 250 kilometres, and two-driver endurance races held at Sandown, Bathurst and Gold Coast. The series is broadcast in 137 countries and has an average event attendance of over 100,000, with over 250,000 people attending major events such as the Clipsal 500.
