Supercar

V8 Supercar is the main motor racing series in Australia. A V8 Supercar is a five-litre V8 powered sedan, and races are held in all states of Australia as well as New Zealand and China.

The Australian Touring Car Championship evolved into V8 Touring Cars in the early 1990s. The company AVESCO was chartered to take the corporate rights of the ATCC from 1997, and invented the moniker "V8 Supercar". The series is known now by the name "V8 Supercar Championship Series", and the winner is awarded the "Australian Touring Car Championship".

Development of the regulations
To the disappointment of a majority of fans who had watched a long history of Ford-Holden battles in Australian touring car categories since the 1960s, international touring car regulations (which moved from Group A to Supertouring) seemed destined to preclude the Australian-built Holden Commodore and Ford Falcon in the early 90s. However, this was avoided with V8 only regulations being drafted, in partnership Ford and Holden, to showcase their large Australian made cars.

Nissan who had dominated in the early 90s had their Turbo AWD Skyline GT-R controversially excluded from the series, whilst BMW (with their non-turbo M3s) were allowed to continue. Nissan vowed never to return to touring car racing in Australia again, and a short time later ceased Australian production.

Eventually the BMW team of Paul Morris left to head a separate new Australian Super Touring Championship (ASTC), and in the mid 90s this ST series ran in opposition to the V8 category. Super Touring with its many makes had the backing of the Australian Racing Drivers Club and sensationally two Bathurst 1000s were held each year in 1997 and 1998, one for V8s and the other (backed by tradional custodian ARDC) for ST. The bulk of sponsorship, driver talent, and fan attention remained with the more popular V-8 category during this era leaving the ASTC to later collapse as an amateur category.

The Car
The regulations are designed to balance the desire for technical competition and fast vehicles with the requirement that costs are kept reasonable. Racing is close, and the cars bear some resemblance to production models.

Power: A V8 supercar is powered by either a 5L Ford SVO or Chev Aurora race engine (depending on the make) which produces approximately 650hp. Engines are have pushrod actuated valves and electronic fuel injection. Both Ford and Holden engines are based on racing engines from their respective US parent companies. Engines are restricted to 7500 rpm.

Weight: The minimum category weight is 1355 kg.

Cost: Reported to be approximately $AU 400k per car and $AU 100k per engine.

Bodyshell: Each V8 Supercar is based on either Commodore or Falcon production bodyshells, with an elaborate roll cage constructed into the shell from aircraft grade materials. Other modifications include wider wheel arches.

Some common components: differentials and gearboxes are identical in all cars in the category.

Suspension: Basic front suspension configuration is double wishbone, whilst rear suspension is a "live axle" design. Spring and damper design is unrestricted.

Tyres: A Dunlop "control tyre" is supplied to all teams. During the year, there are large restrictions on the number of testing days, along with the number of tyres used during those days. During race meetings, teams are allocated a set number of tyres for the entire weekend.

Aerodynamics: A standard "aerodynamic package" of spoilers and wings is supplied to the teams of each make. Testing is conducted so the two makes have as similar aerodynamic characteristics as possible.
