Newly crowned Dunlop Super2 Series champion Broc Feeney says he has "proved his doubters wrong" in claiming the 2021 title.
Feeney finished second behind Jordan Boys in an incident-filled Race 2 in Bathurst to become the youngest ever driver to win the Dunlop Series.
It marked Triple Eight Race Engineering’s first Super2 title since 2011 in Feeney’s final Super2 start.
The 19-year-old will make his full-time debut in the 2022 Repco Supercars Championship.
Feeney will replace the retiring Jamie Whincup to partner champion-elect Shane van Gisbergen at Red Bull Ampol Racing.
"That's been my biggest thing, I said, if I win the championship, I think that I should be deserving to move up,” Feeney said.
"I felt like I wanted to go with a bang.
"I wanted to win that race, and I think that I showed that I had the pace to do that.
"I wanted to go out as a worthy champion, I'm not here to make up the numbers.
"I’m here to win races, and that was my whole goal this year to win as many races as I can to wrap up the championship.
"I know [Roland Dane] has been very good to me and given me a massive opportunity, and so have many people [around me] but hopefully this shows the people that doubted me that I'm here for a reason."
Feeney held a 129-point lead over Tickford Racing driver Zak Best heading to the Repco Bathurst 1000 season finale.
He put one hand on the title on Friday when he won the season opener.
He won Race 1 at Mount Panorama in February, before running rampant in the Townsville doubleheader.
"Oh man, it means the world to me,” Feeney said of the title win.
"It's been a crazy year, we've been very dominant, but it's still like down to the last race.
"It's been amazing, I've put so much effort in not only myself but everyone supporting me.
"We’ve put a massive effort in this year, and to be sitting here with these two trophies is pretty exciting."
Feeney will make his second Repco Bathurst 1000 start alongside Russell Ingall in Sunday’s Great Race.
The 161-lap Repco Bathurst 1000 will commence at 12:15pm AEDT on Sunday.
Supercars will return to the track on Sunday for the Warm Up at 9:10am AEDT.
Every session of the event will be broadcast live on Foxtel (Fox Sports 503) and streamed on Kayo.
The Seven Network will provide live free to air coverage of the event.
