Scott McLaughlin celebrated defending his Supercars drivers' championship and winning the teams title after finishing fourth in the Newcastle 500 on Sunday.
The 26-year-old shook off a month of at times spiteful controversy to back up his second-place finish on Saturday behind series runner-up Shane van Gisbergen and win the drivers' crown.
Seven-time champion and pole-sitter Jamie Whincup demonstrated his liking for the Newcastle street circuit on Sunday by taking the chequered flag for his second win in the event, ahead of McLaughlin's DJR Team Penske teammate, Fabian Coulthard, and Brad Jones Racing's Tim Slade.
I'm so glad that we can finally celebrate.Scott McLaughlin
McLaughlin had wrapped up the title in the previous round at Sandown, robbing the Newcastle race weekend of the tension of previous years, but he was a relieved and elated figure at the end of Sunday's race.
McLaughlin celebrated with a burnout which blew out his rear tyres before standing on the roof of his Ford Mustang at the end of pit lane with a "BACK TO BACK" sign in his hands.
"I'm so glad that we can finally celebrate," McLauglin said.
"I'm pissed off I didn't blow both tyres but I blew one of them. I'm just glad it's all done and I can't wait to party tonight."
McLaughlin set record after record in claiming the 2019 title by 562 points from Holden's Van Gisbergen. His outstanding year including 18 victories and 15 polls, with teammate Fabian Coulthard also claiming two wins in the dominant season by the Mustang.
Whincup's Triple Eight teammate Shane van Gisbergen, who won in dominant fashion on Saturday, was uncharacteristically off the pace in qualifying on Sunday morning, missed the top-10 qualifying shootout and finished seventh.
The results meant DJR Team Penske wrapped up the teams championship.
Whincup said after a poor start to the season the team finished strongly.
We didn't have much performance at the start of the year, but we chipped away and chipped away and the two wins this weekend for the team gives us confidence going into next year that we can be contenders.
"Unfortunately, car 17 disappeared up the road a bit this year, but congratulations to Scotty he did a great job."
Off the track, chief executive Sean Seamer said he hoped Supercars, which has an option to extend its contract to race in Newcastle from five years to 10, would have a "very long future" in the city.
"We're only in year three of a five-plus-five agreement, so we won't start to look at renewal discussions and what that looks like until this time next year at the earliest," he said.
But he said the feedback from City of Newcastle and Destination NSW, the other parties to the agreement, had been "extremely positive".
"We see this event as a landmark event. It's important to the state; it's important to Newcastle. We'll work through with all the different constituents to make sure that hopefully we've got a very long future up here."
