The event originally usually took place in February and March, contributing to what locals term "mad March", along with the
Adelaide Festival,
Adelaide Fringe,
WOMADelaide and
Adelaide Writers' Week. In October 2020, it was announced the
South Australian Tourism Commission would withdraw support for the event, putting the event on hiatus. It returned from the 2022 season as the season finale in late November or early December.
1999 The
1999 event saw
Craig Lowndes win the Saturday race, only to be disqualified due to his involvement in an accident with Danny Osborne, and made to start from the back of the grid for race two on the Sunday. Lowndes passed every car in the field to also win race two and thus become the first winner of the Adelaide 500, in what remains his only event victory. Lowndes' disqualification from race one was later overturned. The 1999 race was also controversial, as the 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 leg, the regulations were changed overnight to allow those cars to start the Sunday race. The inaugural event also proved a challenge to the fitness of the drivers, with both
Paul Radisich and
John Faulkner requiring medical assistance due to dehydration.
2000s The
2000 event once again saw a last-to-first drive, with
Mark Skaife winning the Sunday race after starting 38th due to a DNF on Saturday. In
2001 Clipsal 500, Craig Lowndes won his first race for
Ford since his defection from the
Holden Racing Team to a
Gibson Motorsport Ford. After winning the Saturday race, he was again in contention on Sunday until an incident with his former teammate Skaife ended his charge.
Holden had dominated the event from 1999 to
2003, with three wins to Skaife and one each to Bright and Tander following Lowndes' inaugural event victory. It wasn't until
2004 that a Ford driver won the event, with
Marcos Ambrose winning both races, repeating the feat in 2005. Ford's turn of fate was signified by a sweep of the top four in the Saturday race of the
2005 event. The 2012 Clipsal 500 provided one of the event's most memorable finishes when Whincup chased down and overtook
Will Davison on the final lap of the Saturday race. Whincup had made an additional pitstop and gained enough ground to take advantage when Davison's car began to run out of fuel. Davison went on to win the event with a win on Sunday, his first since joining
Ford Performance Racing. The
2013 event was the first of the Car of the Future regulations, which saw
Nissan and
Mercedes-Benz join the series as the first manufacturers outside
Ford and
Holden since
1993. The Sunday race was won by
Shane van Gisbergen in the aftermath of his controversial decision to announce his retirement during the
2012 season before switching teams to
Tekno Autosports over the off-season. Van Gisbergen swept the
2017 and
2018 editions of the event, taking four poles and four race victories in a return to the two by 250 km format. The 2018 victory, in the twentieth running of the event, was the first victory for the
Holden ZB Commodore in its debut appearance. 2018 also saw the state of South Australia hosting two championship rounds for the first time since 1977 with
The Bend Motorsport Park in
Tailem Bend joining the calendar. In the return of the
Ford Mustang nameplate to the championship in
2019,
Scott McLaughlin achieved the same feat as van Gisbergen, winning the first championship race and
round for the
new car on debut. It was also the first race and round win for the Mustang nameplate since
Allan Moffat at
Oran Park in
1972, while McLaughlin's
team's co-owner
Dick Johnson had also won a
non-championship race at the Adelaide Street Circuit in a
Ford Mustang GT in 1985.
2020s In the week leading into the
2020 Adelaide 500,
General Motors announced that the Holden brand, which was founded in Adelaide and has competed in every edition of the championship since its inception, would be retired by the end of the year. The factory Holden team, run by Triple Eight Race Engineering, won the first race of the weekend with winner Jamie Whincup dedicating the win to Holden. Whincup's team-mate van Gisbergen was leading the Sunday race until he was forced to make an additional pitstop for fuel due to a team error and then later suffered a mechanical failure and did not finish. This granted 2019 winner McLaughlin with a back to back event win.
Hiatus (2020–2021) In October 2020, the event was cancelled, with the
South Australian Tourism Commission announcing that the contract would be terminated one-year early and no renewal will be sought. were cited by
Premier of South Australia Steven Marshall as reasons for the event's demise. The Supercars category released a statement shortly after the announcement stating its regret at the decision and willingness to return to Adelaide should the government decide to hold the event again.
Return (2022) South Australian Opposition Leader
Peter Malinauskas launched a campaign via a South Australian Labor Party petition platform to restore the event, and indicated an intent to return the Adelaide 500 should his party win government. Malinauskas committed to reinstate the race in the leadup to the
2022 South Australian state election at which he was elected premier. The Adelaide 500 returned as the final round of the
2022 series, taking place late November or early December. South Australian-based manufacturer of
LED lighting and
digital displays for sports, then known as VALO, acquired naming rights for three years, as chief commercial sponsor. After changing its name to VAILO in May 2023, ==Format==
