Supercars rule book locked in for 2026

Supercars has locked in a series of rulebook updates ahead of the 2026 Repco Supercars Championship.

Formats for the new season were released last year, with the 2026 campaign expanding to 14 rounds and 37 races.

After some of the most sweeping rule and format changes in the championship’s history were released for 2025, the 2026 rule book represents stability. All rules for the 2026 Repco Supercars Championship can be viewed here.

After Round 9 at Queensland Raceway, the season will switch to enduro mode at The Bend and Bathurst, before the Finals sees 10 drivers chase the championship across seven races at Surfers Paradise, Sandown and Adelaide.

There has been a change to The Finals format, where if a Finals Driver has been eliminated, they lose Finals bonus points and commence the next round on the points that they finished on at the conclusion of Bathurst, plus points accrued thereafter.

In short, drivers who perform across the full season are rewarded, meaning a driver who missed The Finals can rise into the top 10 by season’s end, and eliminated drivers could drop out.

The bonus points allocation for the bp Adelaide Grand Final has also been tweaked to match the bonuses for the Elimination and Semi Finals, with drivers ranked with bonuses of 150 points, 120, 96 and 78.

There has also been a reduction in practice. Single 45-minute sessions will be held in Sydney, Darwin and Townsville, which will see races on all three days.

The Taupō, Christchurch, Tasmania, Perth, Ipswich, Gold Coast, Sandown and Adelaide rounds will have dual 25 minute practice sessions, down on 30 minutes.

Fuel capacity remains 133 litres for Repco Sprint Cup rounds, but will be reduced to 121 litres for the Ryco Enduro Cup and The Finals, where fuel towers will be used.

A key change for 2026 is the make-up of the Pit Lane Order, with Brad Jones Racing downsizing to three cars, and SCT Motorsport becoming a one-car team, albeit with support from Triple Eight Race Engineering.

The SCT entry will be combined with the third BJR car in pit lane, as nominated by BJR.

The tyre allocation for each car has also been locked in.

Tickets for the upcoming Sydney 500, on February 20-22, are on sale now.
