In what is the first serious test for the ZB, Triple Eight Race Engineering will be undertaking a closed Accredited Manufacturer (ACM) test at Queensland Raceway. Van Gisbergen, Lowndes and Jamie Whincup are all expected to drive.

It’s expected to be the ZB’s last run before December’s Supercars aerodynamic homologation testing, where the new Holden will be evaluated for downforce and drag alongside the current Ford Falcon FG X and Nissan Altima L33 Supercars.

The prototype ZB remains fitted with the existing V8 Supercar engine rather than its intended twin turbo V6 powerplant. Testing of the new V6 engine has thus far been carried out aboard the team’s ‘Sandman’ Supercars ride day car, but the new engine is currently undergoing a major upgrade and won't be seen again until the new year.

The existing V8 engine will continue to serve into the new year, with the new V6 scheduled to appear as a wildcard at several rounds ahead of the V8’s 2019 phase-out.
