High Quality Content by WIKIPEDIA articles! The 2008 Clipsal 500 was the first race of the 2008 V8 Supercar season. It was held on the weekend of 21 to 24 February around the inner city streets of Adelaide, the capital of South Australia. The Adelaide 500 is a unique event where the round results are determined by the results from the second race, rather that the driver with the most points from the weekend. This means that the winner of the round does not necessarily lead the championship after the event.
