The 2026 GB3 Championship is a motor racing championship for open wheel, formula racing cars scheduled to be held across Europe. The 2026 season will be the eleventh organised by the British Racing Drivers' Club in the United Kingdom, and the sixth season under the GB3 moniker after rebranding from the BRDC British Formula 3 Championship in mid-2021. The championship will feature a mix of professional motor racing teams and privately funded drivers. The season is scheduled to be run over eight triple-header rounds, starting in April and ending in November. [1]
After the introduction of the Tatuus MSV GB3-025 in 2025, 2026 will see another aerodynamic upgrade to the chassis package. [2] The Mountune engine, previously a two-litre unit, will be upgraded to a 2.4-litre engine, thereby providing a 25% torque increase. All cars run on Pirelli tyres. [3]

The series will not return to Circuit Zandvoort, where it had been racing since 2023, and Monza Circuit will also not return after its debut in 2025. Instead, GB3 will debut at the Red Bull Ring and at Circuit de Barcelona-Catalunya. [7]
