# 2025 AU3 Championship

The 2025 AU3 Championship is a scheduled Australian racing series for Formula Regional open-wheeler race cars. It will be the inaugural season of the AU3 Championship, organized by the promoter of the Australian Formula Open series, two-time Australian Gold Star winner Tim Macrow. The championship will feature drivers competing in cars that conform to the current FIA Formula Regional regulations.
Drivers compete to win a fully-funded multi-day test program with a GB3 Championship team.

## Entry list

All drivers will compete with identical Tatuus FT-60 chassis cars powered by either Toyota or Alfa Romeo engines. The championship will use the cars raced in the Formula Regional Oceania Championship as part of an agreement that sees the chassis shipped from New Zealand to Australia and vice versa after each championship has concluded.

## Race calendar

The 2025 calendar was announced on 20 December 2024. The championships' inaugural season is scheduled to consist of six race weekends, all held in Australia, with the date and venue of the final round - planned to be held in New Zealand - yet to be revealed.
