The 2025 AU4 Australian Championship is an upcoming motor racing series in Australia for Formula 4 cars. The series was previously known as the Formula 4 Australian Championship. It will be the seventh national championship in Formula 4, and the first under the name of AU4.

The series is sanctioned by Motorsport Australia.

Globally, Formula 4 is the first step out of karting on the FIA Global Pathway from Karting to Formula One. It is no longer the only series on the pathway run in Australia, with the introduction of Formula Regional Australia in 2025.

Structure

Significant changes have been made to the championship for 2025 along with the name. The new promoter for the series is AGI Sport, who have been the most successful team in Australian Formula 4, replacing the China-based Top Speed organisation.^[1][2]

There will be two types of car on the grid simultaneously; the Tatuus F4-T421 with the Abarth engine (termed "Gen 2") used in the 2024 championship, and the Mygale M14-F4 with the Ford engine used from 2015 to 2019 ("Gen 1").^[1] The two will be treated as separate classes, and will be separated on the starting grid. Only Gen 2 cars will be eligible for the overall championship. This is not typical in Formula 4 Championships, which are usually single-class spec series in which all participants are in identical vehicles.

The minimum age for drivers in the Gen2 (Class A) cars is 15, and 14 for the Gen1 cars. There will be cups awarded to the best 14-17 year old driver in Gen1 cars ("Class B") & best 30+ driver ("Masters").^[1]

According to Motorsport Australia, the changes are to enable the broadest range of participants in the series, including (older) owner-drivers racing for enjoyment (and not aiming for a professional career overseas), and junior drivers seeking affordable racing experience in open-wheelers, as well as those contesting for the overall win in the latest generation F4 car.^[1]

Championship standings

Points are awarded to the top 10 classified finishers in each race. Each round there is also one point for pole position in each of the two qualifying sessions and one point for fastest lap in each of the three races. In Gen 1 and Gen 2, only a driver's best twelve finishes are counted for the championship.^[16] While Gen 1 and Gen 2 award points per finishing order in each class, in the Masters category points are awarded based on a driver's outright finishing position in each race. The driver who accumulates the highest points total in all rounds will be declared the Masters Winner.
