The Mustangs are set to dominate the Supercars meet at the Australian Grand Prix, with Scott McLaughlin leading four Fords at the top of the timing charts in practice.
McLaughlin was two-tenths away from breaking the practice lap record set by DJR Team Penske garage-mate Fabian Coulthard, scorching the Albert Park circuit with a 1:54.5518 lap on Thursday.
Coulthard was second ahead of two Tickford Racing entries, Chaz Mostert and Cam Waters.
All six Fords in the 24-strong field were among the top 10.
Mostert, battling a nasty cold but still fastest in the first practice session, was honest about whether his Mustang could get close to the dominant DJR entries.
