A final decision on whether Winton retains its round will be made in the lead-up to the Sandown event in mid-September.

Winton has been a mainstay on the V8s calendar since 1985.

But its latest agreement with Supercars Australia ended after the event earlier this year.

The sticking point in the present negotiations between Benalla Auto Club, which owns the Winton track, and Supercars Australia is the hosting fee.

The club is being asked to pay a 50 per cent higher fee to stage the event, but sources said BAC had offered to stump up less than what was paid in the now expired three-year deal.

BAC is in talks with the Victorian government about helping Winton retain the event which attracted 70,000 fans over three days this year.

Supercars Australia general manager communications Nick Johnston said talks were ongoing and assured no final decision on the Winton race had been reached.

"The agreement expired this year," he said.

"We are currently talking to them and those talks are continuing.

"We will have decision before our calendar is released next month."

The Victorian government recently contributed $1 million towards a track upgrade at Winton.

A Geelong V8s race is not an immediate priority, but a second South Australian track at Tailem Bend, east of Adelaide, near Murray Bridge, will be ready to race in 2018.

A V8s race is already held on a street circuit in Adelaide each year.

Supercars Australia has also received expressions of interest from China, Thailand, Singapore and Indonesia.

A round was due to be held on the streets of Kuala Lumpur earlier this month following successful five-car exhibition races last year.

But, the event became embroiled in a legal dispute between promoters and had to be put on hold.

It is scheduled to go ahead next year.
