Revealed: Which four drivers are Gen3's biggest movers?

We're two seasons into the Repco Supercars Championship's Gen3 era, and only four drivers have improved year-on-year in the new-for-2023 cars.

Brodie Kostecki and Will Brown have taken out the two Repco Supercars Championships in the modern Camaro versus Mustang era, with Chevrolet two from two.

Kostecki encountered a big drop in 2024, primarily due to his absence from the first two rounds of his title defence. Had he completed all events with the same average points per round, he still would have wound up 11th.

Brown, though, is one of four drivers to keep moving forward in the championship since the start of Gen3, along with Triple Eight Race Engineering teammate Broc Feeney, Tickford Racing star Thomas Randle, and PremiAir Nulon Racing driver James Golding.

Randle and Golding have gained a combined 18 positions each in the championship in the last two seasons, easily making them the two quiet achievers of Gen3.

Randle and Golding ended the final Gen2 season in 2022 buried in the standings, Randle a lowly 23rd and Golding 25th after joining PremiAir mid-season.

In 2023, Randle jumped to 13th, and Golding 16th. Both drivers were regulars of the top 10 in 2024, claiming poles and podiums, and ended up fifth and seventh overall.

Former Erebus Motorsport driver Brown and Feeney, meanwhile, finished 14th and sixth in 2022, before vaulting to fifth and third respectively as they took a liking to Gen3 machinery.

In 2024, the duo set the pace with Triple Eight, finishing first and second. For both drivers, it was a third consecutive season moving forward year-on-year, and second in Gen3.

The biggest 2023 versus 2024 mover was Matt Stone Racing recruit Nick Percat, who arrived at MSR after two poor seasons at Walkinshaw Andretti United.

Percat was a lowly 20th in 2023, but won two races with MSR en route to eighth. Teammate Cameron Hill also impressed, jumping from 23rd to 13th, a net gain of 10 positions.

The most consistent driver in the championship standings has been Chaz Mostert, who bookended his fourth position in 2023 with third-place finishes.

Andre Heimgartner finished 10th in 2022, improved to seventh in 2023, but dropped back to 10th as Brad Jones Racing struggled for consistency.

It was a different story for veterans Mark Winterbottom, David Reynolds, Will Davison, Tim Slade and James Courtney, who weren't able to translate experience with low-downforce Supercars into results.

Notably, Reynolds, Courtney and the retiring Slade went backwards after 2022, while Winterbottom and Davison didn't make sizeable inroads in 2024.

The 2025 season will commence at Sydney on February 21-23. Tickets are on sale now.
