2026 GB4 Championship

Tatuus MSV CB4-025

The car, which has raced in GB3 as the Tatuus MSV-022 since 2022 was introduced to the GB4 Championship in the 2025 Season.  The CB-025 was a significant upgrade to the F4-T014 package previously used in GB4, introducing key safety features such as the halo to the championship for the first time.

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

A lower downforce single-plane front and rear wing setup with a shortened diffuser was introduced.

Each GB4 Championship race weekend includes a 18-minute qualifying session and three 20-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 third race is a  tope 12 grid reversal with extra points awarded for positions gained as well as for each driver’s finishing position. All scores count towards a driver’s end-of-championship position.
