Adelaide Supercars: Scott McLaughlin earns Mustang double

The DJR Team Penske driver led home a Mustang one-two, finishing the time-certain race with a 2.3 second advantage over Tickford driver Cam Waters.

After a 20-minute delay to the start thanks to late repairs to the Turn 1 tyre bundle, McLaughlin and Shane van Gisbergen kick-started proceedings in sensational style.

The pair rubbed panels as they went side-by-side through the first chicane - the Penske Ford driver narrowly holding onto his lead after a battle that continued up to Turn 6.

Having staved off van Gisbergen's early challenge, McLaughlin could quickly build a lead which grew to over 10s by the time van Gisbergen made his first stop.

He returned in what was effectively third, and put another second on Waters, only for a stranded Jack Le Brocq to cause the first safety car of the weekend.

The majority of the field dived for the pits, and it ended in chaos. The instigator of the drama was Chaz Mostert, who was released into the path of Rick Kelly. The Nissan driver stayed on the throttle and t-boned the Mustang, all but blocking the pitlane.

Mostert, who eventually backed up and got going, was swiftly punished for the unsafe release by a drive-through penalty.

When the race restarted on lap 30 it was Reynolds who dived by Nick Percat for the effective lead, the pair having not pit under the safety car.

McLaughlin was in third, having taken on some extra fuel, followed by Waters and van Gisbergen who both did likewise.

Having spent the middle stint behind Reynolds and Percat, Waters kick-started the final round of stops on lap 44.

McLaughlin followed suit a lap later, emerging just ahead of the Monster Mustang after a slightly slow stop due to a left-rear rattle gun issue.

Van Gisbergen opted to play the long game, holding a 25s lead out front in hope of another safety car, but came in for his last stop on lap 56. He popped out in third, 7s off the lead.

Better tyre quality helped him close the gap over the remaining laps, but he was unable to inflict any meaningful damage, despite climbing all over the back of Waters for the final few laps.

In the end it was McLaughlin over Waters to the tune of 2.3s, van Gisbergen just six-tenths back in third.

Behind van Gisbergen there was a gaggle of Holden drivers led by Brad Jones Racing pair Tim Slade and Nick Percat.

Mark Winterbottom capped off his debut weekend as a Holden driver with sixth ahead of Jamie Whincup.

Will Davison was the next-best Mustang in eighth, with Reynolds and Todd Hazelwood rounding out the top 10.

Fabian Coulthard dumped serious points having copped a drive-through for clattering into Garry Jacobson. He ended up 20th.
