The 2025 Repco Supercars Championship is officially in the rear view mirror, and so is another year of inter-team rivalries.
With some teammates looking to turn the tables after 2024, and some exciting new combinations, there was plenty of intrigue as to how the inter-team battles would play out in 2025.
So, who won the battle in each team? Supercars.com takes a look at the numbers.
Red Bull Ampol Racing
Qualifying: Broc Feeney 32-2
Race: Broc Feeney 23-10
After losing the 2024 championship to new teammate Will Brown, Broc Feeney came back with a vengeance in 2025, dominating his teammate on every metric. However, final day heartbreak saw Feeney fall behind Brown in the final standings.
Penrite Racing
Qualifying: Matt Payne 25-9
Race: Matt Payne 24-9
With a rookie teammate in Kai Allen, Matt Payne comfortably led both head-to-head match-ups throughout the season. However, Allen rose to the occasion in the Finals Series, with both head-to-heads reading 5-4 in the Kiwi's favour.
Walkinshaw Andretti United

Qualifying: Ryan Wood 20-14
Race: Chaz Mostert 18-12
A championship season for the Walkinshaw squad, however Mostert was forced to push himself to new heights amid a brilliant second season for Ryan Wood. The young gun had his veteran teammate's measure over one lap, whilst Mostert returned serve in races, though Wood endured countless instances of misfortune.
Tickford Racing
Qualifying: Cam Waters 26-8
Race: Cam Waters 24-8
Cam Waters continued to lead the charge for Tickford in a season that fell away after a dominant start to the year in Sydney.
Team 18
Qualifying: Anton De Pasquale 25-8
Race: Anton De Pasquale 24-8
After leaving the Shell V-Power Racing Team, Anton De Pasquale put his mark on Team 18 immediately. De Pasquale led both head-to-heads over David Reynolds, a former Bathurst 1000 winner no less, comfortably as the incoming GM homologation team lifted from 10th to fifth in the teams' standings.
Shell V-Power Racing Team

Qualifying: Brodie Kostecki 30-4
Race: Brodie Kostecki 26-5
Brodie Kostecki's arrival promised big things, and the signs were certainly there with a three-win season, by far DJR's most successful of the Gen3 era.
Brad Jones Racing 8/14
Qualifying: Andre Heimgartner 18-16
Race: Andre Heimgartner 21-12
One of the most evenly matched teammate match-ups in 2025, BJR's lead combination of Andre Heimgartner and Bryce Fullwood both struck form in different stages of the campaign. Heimgartner will face a new challenge in 2026, as race winner Cameron Hill replaces Fullwood.
Matt Stone Racing
Qualifying: Cameron Hill 25-9
Race: Nick Percat 17-14
Another tale of two halves is that of Matt Stone Racing, with Cameron Hill and Nick Percat sharing honours. Both drivers also tied with three podiums for the year, though Hill did claim the team's only win of the season, leading home Percat at the Australian Grand Prix in a 1-2.
Erebus Motorsport
Qualifying: Jack Le Brocq 21-13
Race: Jack Le Brocq 20-6
Whilst Jack Le Brocq might have had the measure of rookie teammate Cooper Murray over the course of the year, the raw numbers don't do the young gun justice. Whilst it was a rough introduction, Murray only got stronger as the year progressed, and started to put together some impressive performances, most notably at Bathurst.
PremiAir Racing
Rounds 1-11 - James Golding v Richie Stanaway
Qualifying: James Golding 16-13
Race: James Golding 17-6
Rounds 12-13 - James Golding v Jayden Ojeda
Qualifying: James Golding 3-2
Race: James Golding 4-1
In what turned out to be his last season with the team that breathed new life into his career, James Golding once again led the charge, highlighted by a superb Bathurst podium. After jumping into his 2026 ride early following Richie Stanaway's departure, Jayden Ojeda made a Top Ten Shootout appearance in his fifth attempt in Adelaide.
Blanchard Racing Team
Round 1 - James Courtney v Aaron Love
Qualifying: James Courtney 2-1
Race: James Courtney 3-0
Rounds 2-13 - James Courtney v Aaron Cameron
Qualifying: James Courtney 20-8
Race: James Courtney 22-3
The other team to have had a mid-season driver change, Aaron Love's tough opening at Sydney proved his last act for the time being in a Supercar. Perhaps predictably, James Courtney trumped Love's rookie replacement Aaron Cameron, though Cameron claimed a front row start and led laps in Adelaide.
Brad Jones Racing 96/SCT Motorsport
Qualifying: Jaxon Evans 20-13
Race: Jaxon Evans 12-11
In a sign of how far Jaxon Evans had improved year-on-year, the Kiwi notched up several top 10 finishes to start the campaign, before his rotten run of luck and non-scores. That's not to say that Macauley Jones didn't have his moments, notching up several top 10 starts and very nearly a podium in Tasmania.
