Twice V8 Supercars champion Marcos Ambrose could return to Australia in a team run by his NASCAR employer Roger Penske and Ford stalwart Dick Johnson.

Marcos Ambrose on Friday declined to discuss a report that he’s considering returning to Australia to run the V8 Supercars Series for Roger Penske.

The report this week in the Brisbane Courier-Mail was fuelled at Indianapolis Motor Speedway when Richard Petty said it was up to Ambrose if he wants to stay in NASCAR next season.

“If I had something to say, I’d already have said it,” an irritated Ambrose said.

The Australian newspaper said Penske was working with longtime Australian race team owner Dick Johnson to form a V8 team with Ambrose as the driver.

The Tasmanian, a two-time Supercars champion in a Ford, has been in NASCAR full-time since 2006, and with Richard Petty Motorsports since 2011.

“You’ll have to ask him,” Petty said of Ambrose’s return to the NASCAR No.9 Ford.

“It’s probably up to him as much as anything. He’s been good for Richard Petty Motorsports, we admire what he’s been doing for us.

“It’s going to be basically a decision of what does he want to do? Does he want to run all the races, just part of the races, does he want to go home? That’s going to be up to him.”
