Coulthard suffered from sitting right in behind van Gisbergen's Holden lap after lap in the second half of the race in extreme heat and he wasn't able to get any clear air into the front of his car. He fell into the clutches of Tim Slade, Craig Lowndes and David Reynolds as a result and had to fight hard to hold onto fourth place and his championship lead.

"I am pretty pumped with winning the race," the 24-year-old said. "The burnout procedure wasn't too good - I need to work with van Gis on that maybe.
"I just had really good place.
"It was pretty warm out there - I enjoyed it. I had a good battle with Jamie there and I'm stoked."
Whincup was left frustrated with yet another second-placed finish - his fifth of the year - and remains winless in 2017.
"The car was good and we certainly gave it a crack," the six-time champion said. "I got a good start and got out there and disappeared but I didn't have the tyre life for car #17 today so that was the story.
"We certainly made some improvements on the car this weekend which we can take away from here."
Despite falling behind in the standings this weekend van Gisbergen was in good spirits after the race - even joking with McLaughlin about his burnout technique. He paid tribute to his Red Bull Holden Racing team for a solid Sunday.
"I must thank the team. It has been a really tough weekend on our car - a lot of problems. We have just persevered and the car wasn't perfect but we got a third and salvaged a tough weekend."
