Many factors are still to be determined with the return to racing, such as what formats events will use.
All race formats bar the Supercheap Auto Bathurst 1000 are currently up in the air.
“Now we’ve announced the revised calendar, my role within the Supercars Commission has been extremely busy, so I’m not going to have a huge amount of time to e-race in the coming weeks,” Whincup said.
“I might call around and lean on one of the other lads to fill my spot for Car #88, but we’ll no doubt make a decision in the coming days.”
Red Bull has fielded a stack of wildcards throughout the opening seven rounds of the competition, namely Max Verstappen, Craig Lowndes, Garth Tander, Jack Doohan and its Dunlop Super2 Series driver Angelo Mouzouris.
Of his sudden form spike at Charlotte, Whincup did have an explanation.
“The biggest issue I had with my sim last night was braking again,” said the seven-time Supercars champion.
“Usually I would lean on the engineers to help resolve this problem, but they’ve been too busy getting the real race cars ready back at the workshop, so we just haven’t had time to fix those slight problems.
“At places like Watkins Glen and Charlotte, there’s no braking so I’m actually reasonably competitive.
“I started P6 and was leading the race with six or seven laps to go. I got a good restart under safety car then started getting passed by a couple of cars and then boom, got caught in an accident and finished almost last, again.”
