British racer Holly Miall will make the switch to multiple champions KMR Sport for her GB4 Championship return in 2026. 

After a debut season in 2025 largely focused on development, the 18-year-old returns for a second year of single-seater racing with a clear objective: to compete at the front, and secure a seat in the prestigious F1 Academy.

The Essex-born driver spent two years racing in Ginetta Juniors before making the transition to open-wheel racing last season.

For 2026, Miall has joined Kevin Mills’ eponymous squad, a multiple championship-winning single seater race team across numerous categories. 

Since joining the GB4 Championship, the Gloucestershire squad has been at the forefront of the series, transferring its continuous Formula Ford success to slicks and wings. KMR secured the Team’s Championship title for three successive years across 2022, 2023 and 2024, and claimed the Driver’s Championship title in 2023.
