GB4 Championship

MSV's Entry-level Championship for Aspiring F1 Drivers

The Car

The Tatuus MSV GB4-025

MotorSport Vision (MSV) will introduce the Tatuus MSV GB4-025 car into the GB4 Championship from the 2025 season onwards.

The car, which has raced in GB3 as the Tatuus MSV-022 since 2022, will be a significant upgrade on the F4-T014 package currently used in GB4, introducing key safety features such as the halo into the championship for the first time.

Modified to become an entry-level machine, the Tatuus MSV GB4-025 chassis will retain all the updated safety features utilised in current GB3 specification, including stronger side-impact and rollover protection qualities.

A lower downforce single-plane front and rear wing setup with a shortened diffuser will be introduced. In another visual change to the current GB3 model, the conventional overhead airbox will remain a feature in GB4, with a new engine cover to be produced as a result. Aerodynamic performance will be improved over the current GB4 car.

GB4 will depart from the turbocharged engine currently used in both GB4 and British F4, and will instead utilise a two litre, four cylinder, normally aspirated Mountune unit with a specially designed inlet manifold and throttle body configuration. The car will mirror the current GB4 power to weight ratio, allowing the series to continue running drivers who are 15 years old.

The GB4-025 in GB4 specification will retain the Cosworth Electronics SQ6 ECU and the trusted Sadev six speed gearbox with Magneti Marelli gear shift system. The technical package has been evolved to achieve optimum equality and reliability for GB4 competitors.

Introducing the GB4-025 car into GB4 will allow teams currently running the chassis in GB3 the option to retain and modify their existing cars and race them in addition to the new GB3-025 car package that will be introduced next year, or to sell them to existing GB4 operations. MSV will also provide assistance to existing GB4 teams wishing to continue their presence in the series by upgrading to the GB4-025. A buy-back scheme for current generation GB4 machinery will also be offered by MSV.

The first GB4 specification 025 car is already in development at the series’ Bedford Autodrome headquarters, with an on-track testing programme scheduled later this summer, affording drivers currently in GB4 or targeting the series in 2025 an opportunity to test the car.

Event Format

Each GB4 Championship race weekend includes a 15 minute qualifying session and three 18 minute races. The grid for the first two races is determined in qualifying, with each driver’s quickest lap forming the race one grid, and their second quickest laps establishing the starting order for race two.

The grid for the third race features a reversal of the top-12 drivers from qualifying, with the remaining drivers forming up behind them in qualifying order. Additional points are awarded for positions gained in race three, as well as for each driver’s finishing position. All scores count towards a driver’s end of championship position.

The minimum age to compete in GB4 is 15, with the minimum licence requirement being Race Club. Testing is unrestricted.

Points system

In addition to these, points are also awarded in race three for positions gained during the race. So for example, if a driver started eighth and finished first, they would gain seven points, making for a total of 27 points.
