The Aussie category traditionally stacks cars in track position order behind the leader during safety car periods.
That means at times, particularly in longer races like the Bathurst 1000, lapped cars end up between cars fighting for race position on restarts.
Supercars will look to avoid that scenario this year by letting lapped cars pass the safety car and rejoin at the back of the field.
The idea is to not only keep the battle at the front as close as possible, but also keep more cars on the lead lap.
Rule 10.2.9 now reads: In preparation for the end of the SC [safety car] deployment, the SC will:
10.2.9.1 Set the prescribed speed as instructed by the RD [Race Director] on the RMC [Race Management Channel]; then
10.2.9.2 Extinguish all the flashing lights as instructed by the RD on the RMC; then
10.2.9.3 Cars one (1) or more laps behind the leader as per Rule D10.2.2.6 will be instructed via RMC and via the timing screen to pass the line of cars including the SC when between T18 and T19.7.
a) Lapped cars that have not crossed the P3 timing line prior to the SC crossing the S2 timing line will not be eligible to pass the SC.
b) After passing the SC, pitlane will be closed to the lapped cars until they cross the control line on the racetrack.
c) If the RD considers track conditions are unsuitable,…
