With the new regulations set to come into effect in 1993, Ford and Holden were both keen to know the details of the new formula by the end of 1991, putting pressure on the Confederation of Australian Motor Sport (CAMS) to provide clarity on the matter.
In June 1992, the class structure was confirmed:[20] Both the Ford Falcon EB and Holden Commodore VP ran American-based engines, which were restricted to 7,500 rpm and a compression ratio of 10:1.
The distinctive aerodynamics package, consisting of large front and rear spoilers, was designed partly with this in mind, to give the new cars a better chance of beating the Nissan Skyline GT-Rs in those races.
[22] With the new regulations intended to be a parity formula, protests by the Holden teams indicated that the Fords had an aerodynamic advantage after they won the opening three rounds, beating the Commodores comprehensively.
[28] The expansion of the series began in 1998, with the first round to be held in the Northern Territory taking place at Hidden Valley Raceway.
In 1999, a new street race on a shortened version of the Adelaide Grand Prix Circuit became one of the first festival-style events, which would become common in later years.
The small reduction for the Holden teams was quickly addressed with both cars receiving the same front splitter shortly afterwards, but the Falcon's rear wing remained trimmed.
[35] After Holden again dominated in 2001 and 2002, a new set of regulations, dubbed "Project Blueprint", was introduced in 2003 to close the performance gap between the Commodore and the Falcon,[36] thus creating closer, fairer racing.
[37] Project Blueprint was developed by Paul Taylor and Wayne Cattach, who spent two years designing a formula which would eliminate most of the differences between the Fords and Holdens.
The Holdens were now able and required to use double-wishbone front suspension, similar to that of the Falcon, rather than the MacPherson struts used previously, and a Watts link at the rear rather than a Panhard.
The production model was longer, wider, and taller than the rival Ford BF Falcon and outside of the limits set by Project Blueprint.
As a result, the VE race car was granted custom bodywork – namely shortened rear doors and a lowered roofline to meet the regulations.
[3] Multiple new street circuits appeared on the calendar in 2008 and 2009, with new events held in Hamilton in New Zealand,[50] Townsville in North Queensland and at Sydney Olympic Park.
[51] The series' Middle East expansion continued in 2010 with a second round held at the Yas Marina Circuit in Abu Dhabi.
[53] In 2011, TEGA and SEL entered a sale agreement with Australian Motor Racing Partners (AMRP), which had significant financial backing from Archer Capital.
New regulations, dubbed Gen2 Supercar, were introduced in 2017 to allow the use of two-door coupé body styles and turbocharged four- or six-cylinder engines.
The regulations continued previous changes to ensure technical parity between cars, helping to keep power, downforce and drag levels identical.
[68] The current Gen 3 regulations are a complete refresh of the previous generation,[68] with the cessation of volume car production in Australia being a major factor.
The aerodynamics package for each manufacturer is homologated after a series of tests which ensure that the different body styles produce near-identical downforce and drag numbers.
Both the front and rear suspension systems feature adjustable shock absorbers and an anti-roll bar which, as of the introduction of the Gen 3 regulations, can not be adjusted from inside the car[89] The cars use disc brakes supplied by AP Racing on the front and rear, with the master cylinders provided by AP Racing or former control brake supplier Alcon.
[95] Compared to other modern circuit racing vehicles, V8 Supercars are quite powerful, but have relatively little downforce and mechanical grip, making them challenging to drive.
[96] The spool differential, which is very uncommon in modern racing vehicles, also requires a specific driving style unique to the series and makes it hard for drivers used to other categories to adapt quickly.
[112] Only the REC holders are allowed to compete at each event, although "wildcard" entries are accepted for the endurance races, with a maximum of six extra cars on top of the regular 28.
[117] Exact salaries are not disclosed, but former team owner Roland Dane stated in 2024 "...the two top Supercar drivers are earning more than all their European based counterparts racing in GT3.".
[124] The selection between these qualifying formats is influenced by a variety of factors, including the layout of the track, the length of each race, and strategic considerations unique to each event.
[131] The Bathurst 1000 features a single forty-minute qualifying session on Friday afternoon followed by a top ten shootout on Saturday.
During these years, the 500 kilometres (310 mi) endurance races took place at Queensland Raceway (1999–2002)[141] and the Phillip Island Grand Prix Circuit (2008–2011).
Seven shows only seven events live which are Adelaide, Melbourne, Townsville, Sandown, Bathurst, Gold Coast and Newcastle with the rest shown as a highlights package after the races have finished.
Since 2015, Fox Sports has broadcast a similar show, Inside Supercars, a weekly one-hour long program featuring a panel led by Rust and Mark Skaife.
