The 2023 GB3 Championship was a motor racing championship for open wheel, formula racing cars held across Europe. The 2023 season was the eighth organised by the British Racing Drivers' Club in the United Kingdom, and the third season under the GB3 moniker after rebranding from the BRDC British Formula 3 Championship in mid-2021.[1] The championship featured a mix of professional motor racing teams and privately funded drivers. The season was run over eight triple-header rounds and started on 8 April at Oulton Park.[2]
Rodin Carlin driver Callum Voisin won the Drivers' Championship ahead of Alex Dunne at the final race of the season. JHR Developments, the team of third-placed driver Joseph Loake, won the Teams' Championship.
Loake was named as the winner of the Aston Martin Autosport BRDC Young Driver of the Year Award in December, and will receive a test drive with the Aston Martin F1 team, £200,000, plus full membership of the BRDC.[3]
