GB4 race winner Dayton Coulthard will stay with the Douglas Motorsport team as he returns to the championship in 2026.

The 17-year-old made his car racing and single-seater debut with Wayne Douglas’ squad in 2025, and made big steps forward as the year progressed. 

Having claimed a breakthrough podium result in challenging conditions at Oulton Park, the Scotsman established himself as a frequent top-10 contender in the second half of the year. 

Significant raw pace improvements were also demonstrated by a string of top-seven qualifying results across the final three event weekends. 

His maiden victory came in the season finale weekend at Donington Park, where he jumped from sixth on the grid to challenge the race leader in the early stages of the contest, before launching a superbly executed move at the Old Hairpin with two laps remaining. 

Coulthard’s consistency, allied to his strong end to the campaign ensured he established himself as the second-highest placed rookie driver in the standings.  

The karting graduate has resumed testing with the team, and is now gearing up for his second year of single-seater action.
