Six more teams hit the track this week; Dick Johnson Racing and Matt Stone Racing each rolled out a single car at Queensland Raceway on Tuesday.
Cam Waters rolled out Tickford Racing's first Gen3 Mustang in a black livery at Winton on Wednesday, with Penrite Racing also hitting the track.
Garth Tander joined David Reynolds and Matt Payne at Winton, with the five-time Bathurst winner turning his first Penrite Ford laps.
Red Bull Ampol Racing became the first team to test two cars when Shane van Gisbergen and Broc Feeney cut laps of Queensland Raceway on Thursday.
The two test-liveried Red Bull Ampol Camaros clocked up an estimated 650km of mileage between them, with PremiAir Racing also rolling out its first car, also in a black livery.
Thursday's running saw recruit Tim Slade turn his first PremiAir laps alongside returning driver James Golding.
