Mostert's amusing reaction to wild championship burnout

Chaz Mostert had the inaugural Repco Supercars Finals Series nailed, winning his maiden championship.

However, if there was one moment the new Repco Supercars Champion suggested he would have back, it’s his championship celebrations.

The Walkinshaw Andretti United star clinched the 2025 drivers’ title in an absorbing bp Adelaide Grand Final showdown on Sunday, beating Broc Feeney.

As has become tradition, the new champion celebrates their crown with a series of special burnouts in front of thousands of fans on Adelaide’s pit straight.

Shane van Gisbergen set a high bar in 2022, jamming his race boot onto his throttle before getting onto the roof. Brodie Kostecki and Will Brown shredded tyres in 2023 and 2024.

In 2025, Mostert cruised to the final corner, taking in the moment before getting lost in his own smoke. Then, he burned his way to the championship trophy on the start/finish line, where he did a series of loops.

Instead of destroying his tyres, Mostert got out of the car and onto the roof, saluting the crowd before collapsing onto his knees.

When asked on Supercars’ Cool Down Lap podcast presented by Moza Racing what he rated his burnout out of 10, Mostert joked: "Probably a three.

"I had the slowest in-lap I've ever had in my life… I would've just kept going, but they said, 'oh no, you gotta do it down here as well’.

“So, the rears were already fried by the last corner and I think I nearly took out the trophy… I was pretty stoked to make it twice [around the trophy].”

Mostert could be forgiven given the stress of the race, with erstwhile leader Feeney fighting back from a lap 1 collision with Ryan Wood before his engine let him down.

"It was the longest race of my life, but it’s so weird, I couldn’t tell you where the track started or finished,” Mostert wrote in a blog.

"It was just one long tunnel lap after lap. It’s hard to keep yourself motivated in that spot. I was trying to keep the gap to Will Brown behind. That was the only thing that was making me hit my marks.

"Then at 10 laps from the end you think something's going to fail. You start hearing weird noises in the car. The tyre doesn’t feel good, the brake doesn't feel good. It was like, ‘Please hang on, please'.

"Until you go past the finish line, like I did at Bathurst in 2014, you just never know and even then you still can’t believe it."

Mostert will defend his title with the #1 on his Toyota Supra next season.
