Dayton Coulthard will make his single-seater debut in this year’s GB4 championship with Douglas Motorsport.
Coulthard, son of 13-time Formula 1 race-winner and 1991 British Formula 3 runner-up David, has spent the last six years in karting and has so far competed in the British Kart Championship’s X30 Junior and X30 Senior classes.
The 16-year-old has already begun his testing programme in GB4, which this year is introducing a new halo-shod Tatuus MSV GB4-025 car, based on a detuned version of the outgoing machine used for the last three years in sister series GB3.
“I’m looking forward to working with Douglas Motorsport for the 2025 GB4 season,” said Coulthard. “Moving into cars means I’ll have plenty to learn and I believe that the team can definitely help with my development.”
He will partner fellow single-seater rookie Luke Hilton at Douglas, which is making its GB4 bow this year after winning multiple races in GB3.
“We’re extremely excited to be working with Dayton as he prepares for his first races in single-seaters.” said Douglas team principal Wayne Douglas. ”He’s shown lots of promise so far with good progression, and we look forward to working with him to develop that talent as the season progresses.
“The jump from karting to single-seaters is a big one, but one that Dayton is ready for, and we’re hopeful of ever stronger results as he gains further experience.”
Coulthard will be one of two sons of ex-F1 drivers on the grid at the Donington Park season opener in April, as Luca Magnussen has signed with Fortec Motorsports.
