Australasia's biggest annual motorsport weekend kicks off tomorrow, with another unpredictable Supercheap Auto Bathurst 1000 on the cards. Who will be on top? Here are our 10 cars to watch.
Jamie Whincup/Paul Dumbrell
Why they'll win: Triple Eight's prized pair is arguably the best-rounded. They should be expected to be in the top five of every session throughout the weekend.
Why they won't: Both drivers have been subject to curious errors -- some their fault, some caused by others. The lure of a championship crown could also provide distraction.
Scott McLaughlin/Alex Premat
Why they'll win: McLaughlin has been lightning all season, racking up six race wins and leading the points comfortably. Premat has once again underlined himself as a star signing, too.
Why they won't: Championship. No team will be more distracted by points than Shell V-Power Racing -- we saw this at Sandown.
Shane van Gisbergen/Matt Campbell
Why they'll win: The rapid Kiwi approaches the weekend having conceded that he is out of the championship running, which means he can floor it. Campbell was a revelation at Sandown, too.
Why they won't: SVG's results have been in something of a funk since his last win in May. But they'll be just as quick as their teammates, maybe quicker.
Fabian Coulthard/Tony D'Alberto
Why they'll win: Rinse and repeat for the second of Shell Falcon. Coulthard has been stellar for most of the year; his best season in Supercars. D'Alberto is race fit and very consistent.
Why they won't: Coulthard has often come off second best next to his lead rivals. In a straight fight, it's hard to imagine the No. 12 Ford winning at the death.
Chaz Mostert/Steve Owen
Why they'll win: Mostert's back to his best after his 2015 crash. Fourth in the points and two wins reflects this. Owen is rock solid.
Why they won't: Rock solid as he may be, Owen isn't as race fit or speedy as most of the other co-drivers on this list.
Garth Tander/James Golding
Why they'll win: One of the few modern underdogs to regularly punch high at Bathurst. Fourth at Sandown was no fluke, and Tander, in particular, is a fierce competitor.
Why they won't: To keep up with the pace of Red Bull/Shell over six hours is a tall ask for GRM. A race free of safety cars won't do them any favours.
Cameron Waters/Richie Stanaway
Why they'll win: Sandown 500 winners. Waters is ripe, while Stanaway is capable of racing other co-drivers on the grid ... hard.
Why they won't: The Prodrive package. When it's quick, it's incredible. When it's not, all three team cars look one step removed from those at Red Bull and Shell.
Tim Slade/Ash Walsh
Why they'll win: Very nearly contended for victory last year, and the BJR squad has always excelled at the art of strategy.
Why they won't: Slade has struggled to replicate his results in 2017, and is yet to score a podium.
Mark Winterbottom/Dean Canto
Why they'll win: When Winterbottom has the car underneath him to contend with he's world class. But ...
Why they won't: His car has somewhat deserted him this year. Sixth in the standings is flattering -- he has only two podiums to his name, both coming on circuits very different to Bathurst.
Craig Lowndes/Steve Richards
Why they'll win: Two of the most storied names on the grid, with 10 mountain wins between them. Impossible to rule out.
Why they won't: Has the nature of the race moved on from favouring experience?
