DJR Team Penske are pleading for patience from fans before testing and the Supercars season opener at Adelaide later this month where they'll debut their Ford Mustang.
The two-door coupe was unveiled to much fanfare and mixed reviews on Monday in Melbourne.
That much was inevitable after the demise of the much-loved Falcon, which Scott McLaughlin steered to a triumph last season.
Team Penske are confident of holding off powerhouses Red Bull Holden Racing Team to more silverware in 2019; but not in Adelaide.
The season-opening event at the end of February will see the Mustang's debut and there's a gulf between what McLaughlin wants to achieve and what might be possible.
