Matan Achituv will race for reigning champions Elite Motorsport in the 2026 GB4 Championship. The 15-year-old Israeli began karting in 2022, finishing as runner-up in the 2023 ROK Cup Junior Israel Karting Championship.

Alexandros Kattoulas will make his debut in the GB4 Championship with Elite Motorsport this year. The 19-year-old Japanese/Greek driver made his single-seater race debut at Donington Park last September in the GB3 Championship, racing the Tatuus MSV-022 machine that has now been modified for GB4 use in 2025.
