Supercars star Chaz Mostert has ended speculation he will fill Jamie Whincup's seat next year, signing a new deal with Walkinshaw Andretti United in the belief he can win a championship at the ex-Holden factory team.
Mostert had been heavily linked with a move to Triple Eight Race Engineering to replace retiring seven-time championship-winner Whincup at the powerful Red Bull Ampol Racing outfit.
Instead he's committed himself to WAU on a multi-year deal, confident in the belief they are well on the path to emulating his past glories as Holden Racing Team.
"Obviously there's speculation and some list for some fantastic seat out there but to be honest I think I've got the most prized seat in the category," Mostert said.
"To have a team back you 100 per cent ... I think I'm very lucky to be where I am.
"I wouldn't re-sign if I if I didn't believe 100 per cent (that I can win a championship).
"If I can do it? That's another thing."
The 29-year-old joined WAU before the 2020 championship after six seasons with Ford's Tickford Racing team, which included a 2014 Bathurst 1000 title with Paul Morris.
After finishing fifth in the 2020 championship standings, Mostert claimed his first race with with WAU earlier this year in Tasmania.
As well as Supercars ambitions, Mostert said an ownership structure at WAU involving Ryan Walkinshaw and American duo Michael Andretti and Zak Brown was a key part of the attraction of staying put.
As well as being United Autosports co-owner in England, Brown is the chief executive of Formula One powerhouse McLaren Racing.
Mostert said the possibility of opportunities overseas was certainly on his radar.
"The whole COVID world at the moment makes it very hard to even look far into the future about doing that but, yeah, I'd like to say when things open up and restrictions lift and stuff like that I'll be calling those two guys and saying hey, 'what can I get in?'," he said.
"I'd love to try and lean on that."
Mostert's decision tightens the race to replace Whincup, who'll hang up his helmet and replace Roland Dane as Triple Eight's team principal next year.
Dane indicated in April there was a shortlist of six drivers to fill Whincup's seat including highly-rated development series driver Broc Feeney.
