Seven-times Supercars champion Jamie Whincup has won the final race of the season from pole position, after clinching the Newcastle 500 on Sunday.
But Kiwi Scott McLaughlin had the last laugh on his rivals, adding the team championship to his already successful defence of the drivers' crown.
Whincup celebrated the 118th win his illustrious career and fifth of the season, but he missed out on teams honours, when Red Bull Holden Racing teammate Shane van Gisbergen could finish only seventh.
The result allowed McLaughlin (fourth) and fellow Kiwi Fabian Coulthard (second) to guide their Shell V-Power Racing team home for overall season honours.
"We came here with a goal and that was to wrap up the teams' championship," said Coulthard, after his second podium finish in as many days.
"Our results over the weekend have done enough to do that. Our boys at Shell V-Power racing did an unbelievable job and gave us both great cars, so it's a credit to them."
McLaughlin lost his chance of victory, when he stopped early for fuel, before a safety car on the 24th lap allowed his rivals to make up lost time. He and Cam Waters led when the race restarted, but they were at a fuel disadvantage that saw them fall behind through the second pitstop.
The dual titles were sweet reward for McLaughlin, who has had to suffer barbs from rivals who claim his car overstepped power restrictions and gave him an unfair advantage.
His dominance delivered 18 wins from 32 races, including his maiden Bathurst 1000 crown, to take the crown by 562 points.
"I'm so glad to finally be able to celebrate," said McLaughlin. "We won the teams' championship,
too - that's bloody awesome.
"I'm just glad it's all done and we can party now. I can't wait to have a few beers tonight.
"Any time an organisation can win 18 wins in a single car [is great], but then 20 wins as an organisation is pretty impressive.
"Those results come from all the people who put the work in behind the scenes.
When the chips are down, we come back. We don't care what's been said - we just get on with it."
