Ford superstar Scott McLaughlin has produced the greatest drive of his Supercars career to snatch a wild second race of the Perth Supersprint.
The championship leader created history on Sunday by coming from 19th on the grid to secure a famous victory - his fourth straight in the series.
McLaughlin smashed the record for the lowest grid start (12th) to win at the Western Australian circuit, which was previously shared by Peter Brock (1978) and Larry Perkins (1997).
After converting his poles in the previous three races into comfortable wins, the Shell V-Power ace was forced to do it the hard way in the 83-lap affair at Barbagallo Raceway.
McLaughlin admitted he "stuffed up" his qualifying efforts, but benefited from a chaotic opening to the second race of the round where he escaped the carnage that saw Nissan's Michael Caruso forced to the garage.
McLaughlin had made up seven spots after only two laps.
By the time the safety car was called out on lap four after Wilson Security Racing's James Golding was sent spinning towards the sand, McLaughlin had shot up to sixth.
The 24-year-old worked his way through the field after brief leader Will Davison, who was driving in his 400th career race, failed to pit for the safety car.
"It's my best race as a whole that I've had at DJR Penske," McLaughlin said.
""I joked to DJ (Dick Johnson) before we went out and said, 'I reckon we could win this thing' thinking maybe I could but I didn't think it was going to happen."
McLaughlin's fifth win of the season sees him go 158 points ahead in the standings ahead of the sixth round of the season at Winton on May 18-20.
The man behind McLaughlin in the championship, Red Bull Holden's Shane van Gisbergen, started the race in pole but crossed the line in fifth.
Erebus Motorsport's David Reynolds redeemed himself from a poor race on Saturday, where he finished 17th, to drive his Commodore to second.
Fellow Holden driver Craig Lowndes incredibly shot up 22 spots after starting at the back of the grid to end up on the podium in an inspired performance.
