Fox Motorsport has confirmed Saudi karting champion Jasser Iskander as the team’s first driver for the 2026 GB4 Championship season. The youngster will be GB4's first-ever Saudi Arabian contender, and is the 20th confirmed driver on this year's grid, with just under three months still remaining until the start of the season.

Reigning five-time Ginetta Junior champions R Racing will expand into single-seaters for the first time in 2026, with a two-car entry into the GB4 Championship.

Karting graduate Jay Leverton has been confirmed as the first driver in Idola Motorsport’s line-up for the 2026 GB4 Championship.

Dudley Ruddock will make his car-racing debut in the GB4 Championship as he joins forces with Arden Motorsport for the second half of the 2025 campaign.

Ary Bansal and Alex Berg were the winners on the second day of the GB4 Championship season opener at Donington Park, but it was Hillspeed’s Dan Guinchard that left the East Midlands as the early championship leader.
