Inevitably, V6 engines are on their way to the Aussie Supercars grid.

Triple Eight Race Engineering, operators of team Red Bull Racing Australia, got their hands on Holden's new turbocharged V6 racing engine for the first time this week, putting in 256km of testing at Norwell Motorplex on Australia's Gold Coast.

Holden factory men Craig Lowndes, Jamie Whincup and Steven Richards got their first taste of the V6 Supercar engine when they took turns punching out laps in the team's "Sandman" show car retrofitted with the new six cylinder.

Triple Eight boss Roland Dane confirmed the V6 test took place on Monday and Tuesday to Australia's Daily Telegraph.

"Yes we have run it,'' Dane said.

"We ran the engine on Monday and Tuesday."

Details were scant regarding the engine, its performance, or the new V6 program, but Triple Eight has already announced it would enter a V6 engined car as a wildcard entry at some point next year before ditching the V8 at the end of the 2018 season.

But he did hint the engine was powerful enough to replace the beloved V8s.

"The power is not an issue with the turbo."

"But we have to make the delivery as good and as linear as a V8. We don't underestimate the amount of work we have to do. But we are quietly pleased with what we have done so far and we will continue to test behind close doors so we can get it right and be there or there about when we run it as a wildcard next year.''

Dane also said the "Sandman" built for promotional purposes three years ago was the perfect test tool.
"It is the ideal test car,'' Dane said.

"From the moment I saw it three years ago I had it in mind to be a mule test car for whatever engine that would be coming along down the road. GM Racing has done a great job giving us a base.''

Look for more development of the Supercars V6 program in the coming months.
