As the 2025 Repco Supercars Championship rolls into the bp Adelaide Grand Final (November 27–30), the title fight has been distilled into a clean, brutal equation: four drivers, one weekend, no excuses. Race engineer and analyst Scott Sinclair frames it as a clash of contrasting strengths and vulnerabilities, with Adelaide’s street circuit set to reward precision just as much as bravery.

Broc Feeney: control the front, control the crown
Feeney arrives as the favourite and, crucially, the points leader. His 20-point buffer over Chaz Mostert gives him a small but meaningful safety net in a Finals format where margins are usually razor thin. The recipe for Feeney is simple to say and hard to execute: qualify up front and stay there. His season has been built on elite one-lap speed and clean conversion into race results. The wrinkle? If he’s not ahead, he has to pass for it — and that’s where pressure spikes. Sinclair notes Feeney hasn’t overtaken Mostert at all this year and has only rarely found a way past Will Brown, making track position even more vital.

Chaz Mostert: fast enough — but must be flawless
Mostert is the Finals hot-hand, winning three of the last four races to surge into genuine contention. Adelaide’s layout mirrors elements of Sandown and the Gold Coast, two rounds where Mostert’s speed popped, so outright pace shouldn’t be his issue. Reliability might be. Mechanical failures and earlier pit-crew stumbles have bitten Walkinshaw Andretti United more than once in 2025, and a single miscue this weekend could be fatal. For Mostert, the championship path is less about heroics and more about a clean, boring, perfectly executed weekend.

Will Brown: the champion needs qualifying to show up
Brown’s problem is blunt: he’s been starting too far back. Despite being the best passer in the field this season, you can’t spot your rivals a dozen grid spots and expect to win a title decider. His Finals qualifying average has hovered around 15th, and Sinclair argues that’s unsustainable when he needs to beat both Feeney and Mostert head-to-head — something he hasn’t done in a race for 19 straight attempts. Brown’s only real lever is to qualify within striking distance and force the fight early.

Kai Allen: underdog chaos, smart risk
Allen is the long shot, with season-long speed stats that don’t scream “champion.” He’s rarely out-qualified the other three and hasn’t consistently raced ahead of them. Still, he earned his Final Four spot by stacking points and staying in the game. His edge now is freedom: no one expects him to play safe. Strategic swings, Safety Car timing, and capitalising on others’ mistakes are his realistic route to something extraordinary.
