TheAU3 Championship is a planned Australian motor racing series usingFormula Regional cars.
The new series was announced (originally titledFormula Regional Australia) in November 2024 for the2025 season.[1] The new name was announced by the organisers in February 2025.[2] The name aligns with the recent name change of theAU4 Australian Championship.
It will be sanctioned byMotorsport Australia and is promoted byTim Macrow,[1] the organiser ofAustralian Formula Open, another Australian open-wheel racing series using older Formula 3 and Formula 4 cars.
The series will use theTatuus FT-60 cars currently used for theFormula Regional Oceania Championship, which is based in New Zealand and runs in the southern hemisphere summer, leaving them available for use much of the year. However, additional entries using cars sourced from elsewhere using the Alfa Romeo FR engine commonly used throughout Asian FR series will be permitted, along with an Invitational class using older Formula Regional vehicles[3]
It was announced the 2025 season would be cancelled and a new debut season planned for 2026.
