Since they were first partnered six years ago, the duo has won the 2014 Enduro Cup and have featured on podiums at Sandown, Bathurst and the Gold Coast together.

They have been one of the consistently best performed enduro pairings in the Supercars series.

However, they may part ways next year when fellow Triple Eight Race Engineering star Craig Lowndes switches roles from full-time racer to co-driver.

No decision on who Lowndes will partner has been made yet, with both his Triple Eight team-mates Whincup and Shane van Gisbergen keen to have him.

Before the co-driver rules changed to prevent two full-time series competitors to team up for the endurance rounds, Whincup and Lowndes won three Bathurst 1000s together.

Therefore, Dumbrell is viewing this year’s Great Race as if it could be his last with Whincup.

“Bathurst is an amazing experience, every time you go up there you’re really reminded about the great things about the sport,” the 2012 Bathurst 1000 winner said.

“So I'll go up there always with the philosophy that this could be my last and you really enjoy it, take it all in, but you really focus on getting the best result possible.”

After winning the opening round of this year’s Enduro Cup, the Sandown 500, Whincup and Dumbrell are hot favourites for Bathurst.

But again, Dumbrell is taking nothing for granted.

“I think you've got to put it into perspective. Last year we were quite strong [at Sandown] and obviously didn't get the result we wanted, but then we went to Bathurst and weren't anywhere near the money,” he said.

“No doubt the team will go back, really learn about what happened last year and take what we've learned from Sandown and we'll put our best foot forward.”
