Adelaide 500

The Adelaide 500 is an annual motor racing event for V8 Supercars, held on the streets of the east end of Adelaide, South Australia on a shortened form of the Adelaide Street Circuit, the former Australian Grand Prix track. The event is currently known as the "Clipsal 500 Adelaide" due to naming rights sponsorship from Clipsal.

Usually held over four days in early March, the "500" itself consists of two 250 km races for V8 Supercars held on the last two days of the meeting. For much of its life the two races combined to give an overall result for the winner of the Adelaide 500, although the message was often confused as podium celebrations based on the results of each day individually were held. More than most the race regualtions have been fiddled with many times, most famous on the day of the first event where original regulations stated the race was one 500 kilometre race with an overnight break at the 250 km mark. When a significant portion of high profile cars retired in the first day of the original 1999 event the regulations were changed overnight to allow those cars to start the Sunday race. In 2008 V8 Supercars briefly attempted to retrospectively change the winners of past Adelaide 500s to recognise only Sunday race winners, even to the point of changing overall series statistics, but have since reverted. A major regulation change for the championship as a whole in 2009 saw each race in the championship regonised individually and 'round results' were no longer officially recognised. Since then V8 Supercars Australia have stepped away from the concept of an overall two-day Adelaide 500 winner.

Although the results of both races count towards the V8 Supercars, the winner of the second race is declared the winner of the "Clipsal 500 Adelaide", regardless of the results of the first race. The rest of the four days are filled with practice, qualifying, and support races for a number of other racing categories, including Australian GT and Australian Formula Ford.

In 2008 the Clipsal 500 was attended by 291,400 people, the largest crowd for a domestic motorsport event in Australia. The carnival also features a music concert every night, in addition to air displays, amusements, and social events that attract visitors from interstate and overseas.
