A number of late entries have resulted in the field for this weekend’s GB3 season-opener at Silverstone growing to 24 cars.
Among those is Enzo Tarnvanichkul, who has been a member of the Red Bull Junior Team since 2023. The 16-year-old will contest the four British rounds of the series as well as the Monza season finale in GB3 with Velocity Racing Development. He will get his first taste of the GB3 car at Thursday’s pre-event test.
Tarnvanichkul came 12th in Spanish Formula 4 as a single-seater rookie last year, and took a pair of sixth places during his two-round appearance in Eurocup-3’s 2025 Spanish Winter championship.
“I’m proud to be competing in selected GB3 Championship events this season,” said Tarnvanichkul. “The opportunity to race on some of the most iconic circuits in the UK and Europe will be invaluable in my development as a driver. I’m extremely grateful to VRD Racing for the opportunity and of course to the Red Bull academy for their continued support. I’m fully focused on making the most of this experience and can’t wait to get started on track.”
Hillspeed has expanded to a full three-car line-up for round one after signing both Kanato Le and Hiyu Yamakoshi for partial campaigns alongside Freddie Slater. Both will contest the three non-clashing GB3 rounds this year alongside their full Formula Regional European championship programmes.
Le scored two wins in British Formula 4 in 2023 en route to seventh in the standings. Last year he came 18th in FREC, made a GB3 cameo at Spa-Francorchamps and was a non-finisher in the main race at the Macau Grand Prix. He began 2025 by taking one win and finishing eighth overall in FRegional Middle East.
Yamakoshi was a front-runner in both Italian F4 and Euro-4 last year, winning twice in both and finishing third and fourth in the standings respectively. The 18-year-old took part in the final three FRegional Middle East rounds this year, scoring a best result of fifth.
“I’m very happy to be competing in three events of the GB3 Championship with Hillspeed,” said Yamakoshi. “With very limited practice time I know Silverstone will be a very difficult weekend, but I will try to learn as much as I can from my team-mate Freddie who I competed against for the title in Italian and Euro F4 last year. I will do my best to fight for the lead from the start.”
Fortec Motorsports has expanded its assault to two cars, with Mika Abrahams returning to the team with which he took two poles and came 18th overall in British F4 in 2023. He remained in the series with a switch to Hitech GP last year, taking a maiden victory at Donington Park, but his season only lasted four rounds.
“It feels like coming home,” said Abrahams. “I’m grateful for the opportunity to work with everyone at Fortec Motorsports once again, and I am looking forward to a successful season ahead.”
