The 2023 GB4 Championship calendars has been confirmed by series organiser MotorSport Vision (MSV). GB4’s fixture list features seven events, and will appear on the bill at all UK rounds of SRO’s prestigious British GT Championship.

GB4’s usual double visit to the Silverstone Grand Prix circuit remains, the first of these will form part of British GT’s blue riband Silverstone 500 meeting, whilst the second will be a co-headline fixture alongside GB3.

For both categories, the season will start at Oulton Park on Easter weekend (8 and 10 April), and conclude at Donington Park on 21/22 October. Visits to the Snetterton 300 and Brands Hatch Grand Prix circuits are included once more.

The 21-race campaign for GB4 will again feature three races per weekend.

MSV Chief Executive Jonathan Palmer said: “GB4’s calendar builds on the success of an inaugural season that has provided a much needed opportunity for underfunded young drivers to progress their single seater careers. Traditional British circuits offer the perfect learning environment, with circuits like Oulton Park, Snetterton and Brands Hatch, in addition to the Grand Prix circuit at Silverstone, providing challenges that have proved so crucial to the development of numerous F1 stars over the decades.”
