As a direct result, PRA is already working towards a replacement bodyshape for the 2018 Supercars season. And while there is no set decision yet, the future of a Ford model in Supercars should be become clear – internally at least – reasonably early in the year, to allow enough lead time to develop a new aero package.

“Of course we’re thinking about it, and of course DJR Team Penske is thinking about it,” Edwards told Motorsport.com. “But it’s one thing thinking about it, and another being able to afford to do it, have the permission to do it, and all those things.

“There are so many factors that have to be taken into consideration, it’s not as easy as saying ‘we want to race Mustangs next season’, click our fingers, and it happens.

“It’s a conversation we need to be having with Ford, and we need to work through it with the category because there is the homologation of a two-door car, which has not been done yet.

Time is running out for the Ford Mustang to join the Virgin Australia Supercars Championship in 2018, admits Team Penske president Tim Cindric.

The American giant expects to continue with its current Falcons in 2018 unless the Mustang gets the green light from Ford Australia within the next month.

Penkse's Shell V-Power Racing and fellow Ford Supercars team Prodrive have collaborated on feasibility studies into a Mustang program, which needs Ford’s blessing to go ahead.
