Jamie Whincup believes the 2021 Repco Supercars Championship will be wide open, with the seven-time champion predicting up to 15 drivers can take out the title.
With Scott McLaughlin and Penske departing, many believe Whincup's Red Ampol Racing Team, which also features 2016 champion Shane van Gisbergen, will be the ones to beat.
McLaughlin ruled the roost between 2018 and 2020, clinching the 2019 and 2020 titles with a round to spare.
However, Whincup expects the competition in 2021 to be tighter than ever.
"While there's so much new and so much fresh [in 2021], there's still one thing in common… go out there and try and beat your mates to the finish line," the 37-year-old said at his team's launch on Friday.
"The competition this year, I'm predicting it will be tighter again. It's going to be a massive battle for this year's championship.
"There could be 10 or 15 guys eligible for the win this year.
"Fingers crossed both Triple Eight Race Engineering cars are battling it out."
