Chaz Mostert has grabbed provisional pole with a lap record as Supercars drivers continue to set a hot pace in the return to racing around Adelaide's streets.
The Walkinshaw Andretti United star set a time of one minute 18.6763 seconds, smashing champion-elect Shane van Gisbergen's record time from practice earlier on Friday by more than half a second.
Mostert was one of nine drivers to surpass van Gisbergen's mark as the newly-resurfaced circuit produced quick results.
Shell V-Power's Anton De Pasquale and Team 18's Scott Pye rounded out the top three.
But it was disaster for van Gibsergen in qualifying for the Adelaide 500 as he finished 25th and last, stalling on the final corner and heading into the grass when he looked set to record a fast lap.
"My qualifying run was just littered with mistakes," van Gisbergen said.
"The car was very hard to drive, and I was probably pushing a bit too hard and didn't back it down enough.
"I probably should have accepted to try and get into the shootout rather than go all out and I'm pretty pissed off with myself right now.
"(Saturday's) race is going to be tough, but we'll try and get things right for Sunday."
Mostert was thrilled with his time and will look to repeat it in on Saturday for the top ten shootout ahead of the first of two 78-lap races this weekend.
"To top a session is always pretty special and I think this weekend, especially, with Holden finishing up in motorsport, it's hard not to get caught up in those small little session wins you do have," Mostert said.
"I didn't know our car had the time in it ... but to be that fast around here is really cool, the track has got an amazing amount of grip.
Van Gisbergen takes an unassailable 683-point lead into the final round of the season after winning an extraordinary 21 out of 32 races this year.
The Commodore driver is looking to cap off a stellar campaign by winning the two races at the Adelaide 500 this weekend to go with his Bathurst 1000 win and second-straight championship crown.
Mostert believes van Gisbergen will always be a threat and would not count him out of making a serious challenge from 25th.
"It's Shane, we've seen unbelievable comeback drives from him so I'm sure he'll have a good car underneath him," Mostert said.
"He'll make some work for some people, but hopefully we're all starting far enough up that front that he won't catch us."
It has already been an emotional event with Holden fans to finally bid farewell to the famous red lion.
General Motors retired the Holden brand in 2020, announcing it just weeks before the COVID-19 pandemic began, but the Commodore has lived on in motor racing.
However, with the Gen3 cars ready to launch next year, Chevrolet Camaros will replace Holdens on the grid to battle the Ford Mustangs.
