American motorsport giant Roger Penske's decision to enter next year's V8 Supercars championship has been hailed by Jamie Whincup.
The five-time V8s champion says Penske's decision to partner with Ford legend Dick Johnson in a team led by Marcos Ambrose could be a game-changing moment for the Australian championship.
Ambrose, a two-time V8s champion, will return home after eight years racing in the United States backed by the financial might of Penske, whose drivers have won 15 Indianapolis 500s.
Whincup says the situation bears similarity to the arrival of his boss and Red Bull Racing owner Roland Dane, who came to Australia in 2003 to conquer V8s after several years of success in British touring cars.
"They see it as a challenge. Those blokes don't do anything by halves," Whincup told AAP. "They're going to bring a lot to the table and, I've got to say, if the result of that is they raise the bar of the category, that's fantastic.
