The GB4 Championship, partnered by the BRDC, has confirmed its seven-round, 21-race calendar for the 2025 season, which will again feature all the UK’s top circuits, including two events on the full Silverstone Grand Prix layout.
GB4 will run alongside all six UK rounds of the prestigious British GT Championship next season, which for the first time gets underway at the Donington Park Grand Prix circuit (on 5/6 April), where GB4 will be the headline single-seater category, before the first visit of the year to Silverstone, joined by GB3, on 26/27 April.
A month later, GB4 will again take a headline single-seater billing at the Oulton Park rounds on 24 and 26 May, and at Snetterton on 12/13 July.
Silverstone’s return alongside GB3 on 2/3 August comes ahead of the final two events of the calendar at the Brands Hatch (23/24 August) and Donington Park (4/5 October) Grand Prix circuits, with British GT and GB3.
The 2025 campaign will also feature the introduction of the Tatuus MSV GB4-025 car, bringing key safety features into the category, including the halo, plus a revamped technical package featuring a normally aspirated Mountune engine, and several aerodynamic revisions.
