The Level One Australian Touring Car Championship now known as the V8 Supercar Championship Series caters for the 31 fully professional cars run by the 14 two-car and 3 one-car well-sponsored V8 Supercar teams. The series is commercially successful and highly competitive, with races all over Australia, one in New Zealand, and in 2006, the first race in Bahrain. Tracks range from street circuits (such as the Adelaide circuit) to more permanent road courses (such as the Phillip Island Grand Prix Circuit). The largest single event is the Bathurst 1000.
