GB4 Championship

The championship was launched in early September 2021.^[3]

The first round of the inaugural season took place at Snetterton Circuit on 2 April 2022, with the first winner being Nikolas Taylor driving for Fortec Motorsports.^[4]

From 2022 to 2024, the GB4 Championship used the Tatuus F4-T014 car previously used by the Italian, ADAC, Spanish and other F4 championships across Europe.^[5]

The engine is an Abarth-branded, turbocharged Autotecnica Motori 1.4L FTJ I4 and produces 160hp. It features a sequential six-speed gearbox developed by Sadev and Magneti Marelli electronics.^[6]

Starting in 2025, the series will introduce the Tatuus MSV GB4-025, a modified version of the Tatuus MSV-022, used by the GB3 Championship from 2022 to 2024.^[7] The new chassis will feature a Mountune 2.0L engine.^[7]

Costs of running in the initial years of the championship were significantly lower than Formula 4 due to the use of the older Tatuus F4-T014, which could be purchased second hand (as in many cases it was no longer eligible for use in Formula 4). As the GB3 Championship usually runs at the same event weekends and uses a modified version of the same car, many spare parts can be shared if a team runs in both categories.

The organiser states that privateer teams can run in the championship for approximately £60,000, and fully professional teams for around £150,000^[8]

A prize to the value of £50,000 was offered to the 2024 champion if the champion subsequently chooses to compete in either the British F4 championship, or GB3, in 2025.^[9]

One distinctive feature of the GB4 championship is the relatively high number, and competitiveness, of female drivers. In 2024, four of the 21 competitors were women. Alisha Palmowski finished second in the 2024 championship, and received a £30,000 prize to be used to help fund entry into the F1 Academy series in 2025.^[9] In 2025 the price was raised to £50,000 and was won by Ava Dobson who passed Megan Bruce in the Championship in the last weekend of the series at Donington Park.

Points are awarded to the top 20 classified finishers in races one and two, with the third race awarding points to only the top 15. Race three, which has its grid formed by reversing the qualifying order, awards extra points for positions gained from the drivers' respective starting positions.
