Marcos Ambrose is remaining coy on his driving future amid suggestions that the Castrol Gold Coast 600 may be his final V8 Supercars drive.

The Gold Coast is the last of the three Pirtek Enduro Cup meetings that Ambrose committed to upon stepping down from full-time driving in March.

DJR Team Penske confirmed last week that Ambrose elected not to return to a full season with the squad for 2016, but has left the door open for the driver to return for the enduros.

Ambrose says that he’ll wait until after this weekend to discuss his plans, leaving open the prospect that Sunday’s race will be a quiet swansong for the former two-time champion.

“I’m certainly not saying anything this weekend about what’s going on,” Ambrose told Speedcafe.com when asked of his future.

“There is no need to. We need to try and focus on winning this race.

“Co-driver line-ups (for next year) are worked out later on. I’ve got all the time in the world haven’t I?

“I’ll get through this one and we’ll go from there.”

Ambrose was quick to downplay the significance of his father Ross’ trackside appearance this weekend, dismissing suggestions that it is a sign of a major milestone.

The former NASCAR race winner meanwhile drove the DJR Team Penske Ford to 16th and third in the two Friday co-driver sessions, running a single lap on a set of soft tyres in the latter hit-out.

“It’s my first time here in 10 years and there’s only half a track left,” Ambrose said in reference to the track’s current 2.96km length, reduced from its original 4.5km in 2010.

“There’s a lot of corners that have been opened up and it’s a lot faster in the chicanes.

“But I’ve felt pretty comfortable and the times are good, so I’ve enjoyed myself.”

Primary driver Pye pushed through Friday despite feeling the pain of a rib broken in his late race crash at Bathurst when a steering arm broke.

The injury could see Ambrose undertake more of the driving duties during the two 300km races than otherwise planned.

“Scotty is going to be fine for the weekend. He’s just looking after himself so I don’t think we are too compromised,” Ambrose said.

“We’ve just got to think about our strategy for driver changes now. We’ve got to really manage that.”
