SUPERCARS TO TRIAL SOFT TYRES AT BATHURST

THE Repco Bathurst 1000 is likely to be run on a soft compound Dunlop control tyre for the first time in 2023.

Supercars had earlier this year discussed the possibility of producing a new Gen3-specific range of rubber for next season as part of efforts to improve racing.

Instead, Supercars head of motorsport Adrian Burgess says a simpler solution will be deployed using the existing tyres.

“We’ve come down a range in compound, so at tracks before where you probably would be on a hard, you’ll more than likely be on a soft,” Burgess told V8 Sleuth.

“That’s just by virtue of the fact the car weighs a lot less and it’s got a lot less downforce, so you don’t need the harder compound.

“So we will generally run softer than we’ve currently run.”

Burgess confirmed that is likely to apply to Bathurst, where the hard compound has been the go-to due to the demanding nature of the Mount Panorama circuit.

The Gen3 cars will trial running on soft tyres during demonstration laps at next month’s Great Race.

“At the moment we’re going to try soft tyres when we go there (in October),” said Burgess.

“All of our sim and all of our work that we’ve done at the moment points to the fact that we could probably race there on a soft next year.

“But we’re not just going to try without any validation, so we’ll run it there this year for the 1000 and we may probably go back in February for the 12 Hour.”

Besides a Queensland Raceway shakedown, it was at the 2021 Bathurst 1000 that the Camaro and Mustang prototypes cut their very first public laps.

With the front-end of the new control chassis now approved, the path is clear for mass production of the next-gen machinery.

Other important Gen3 timeframes include engine durability testing currently taking place in the United States and an all-important VCAT to measure aerodynamic parity, scheduled for November.

Newcastle is due to host the first event of the Gen3 era across March 10-12, 2023.
