The Red Bull Holden Racing Team has used its Evaluation Day to bank an early test day with their new ZB Commodore at Queensland Raceway.
Super2 driver Kurt Kostecki and American sportscar racer Jordan Taylor both sampled the new car ahead of its official shakedown test on February 9.
Under the regulations, teams can perform an Evaluation Day with the approval of Supercars, provided the driver is not a primary driver at another team, has not been a primary driver in the previous three seasons, and has not competed in five or more Supercars events in the preceding year.
Having competed in the Dunlop Super2 Series last year and yet to make his main game debut as a listed primary driver, Kostecki fits that criteria while it was Taylor's first taste of a Supercar.
The duo were watched on by regular driver van Gisbergen, while Grant McPherson engineered the car, which was launched on Friday in Sydney.
