The 2025 GB3 Championship was a motor racing championship for open wheel, formula racing cars held across Europe. The 2025 season was the tenth organised by the British Racing Drivers' Club in the United Kingdom, and the fifth season under the GB3 moniker after rebranding from the BRDC British Formula 3 Championship in mid-2021. The championship featured a mix of professional motor racing teams and privately funded drivers. The season was run over eight triple-header rounds. It started in April and ended in October.
Rodin Motorsport driver Alex Ninovic won the Drivers' Championship with three races to spare, while his team defended their Teams' Championship title a race later during the final weekend.
Teams and drivers The 2025 season saw the introduction of a new chassis and engine package. The new Tatuus MSV GB3-025 conformed to the FIA Formula Regional regulations while featuring a higher downforce output than its predecessor as well as a drag reduction system. The Pirelli tyres used had their diameter increased by two inches, while the Mountune engine was also redesigned and now provided 30BHP more power.

Team changes
VRD Racing became its own entry in 2025 after entering GB3 in collaboration with Arden International in 2024, while Arden discontinued their GB3 efforts.
UAE-based team Xcel Motorsport expanded into GB3 after first entering the British junior series landscape when it joined British F4 in 2024.
Argenti Motorsport, who had been competing in British F4 since 2020, joined GB3 in a technical partnership with Italian junior single-seater team Prema Racing under the Argenti with Prema guise.
Hitech Grand Prix and Toyota Gazoo Racing's TGR-DC junior programme formed a new collaboration in 2025, entering under the Hitech TGR guise.
Driver changes Reigning Teams' Champion Rodin Motorsport entered 2025 with three new drivers as reigning Drivers' Champion Louis Sharp graduated to the team's FIA F3 outfit, Arthur Rogeon moved to the Le Mans Cup with CD Sport and neither of the team's four part-time drivers of 2024 returned. Rodin promoted British F4 runner-up Alex Ninovic and 2024 F1 Academy champion Abbi Pulling from their outfits in the respective championships, with Pulling receiving a fully-funded seat because of her championship title. Gianmarco Pradel, who finished 7th in Italian F4 with US Racing, completed the team's lineup, debuting in GB3.
Hitech GP also had an all-new driver lineup as William Macintyre moved to Elite Motorsport, Gerrard Xie stepped up to the team's FIA Formula 3 outfit and Tymek Kucharczyk left the team and the series to join BVM Racing in Euroformula Open. Hitech promoted 2024 F4 British Champion Deagen Fairclough from its outfit in that championship, signed USF Pro 2000 Championship runner-up Nikita Johnson, who also came eleventh in GB3 in 2024 with VRD Racing by Arden, and recruited Alpine Academy driver Keanu Al Azhari, who was 2024 F4 Spanish runner-up with MP Motorsport.
Elite Motorsport's three drivers all left the series, with McKenzy Cresswell joining the team's outfit in the GT4 European Series, Jarrod Waberski signing with Century Motorsport in the GT World Challenge Europe Endurance Cup and Hugo Schwarze moving to the Le Mans Cup's LMP3 class with R-ace GP. The team signed two second-year drivers in William Macintyre, who left Hitech Pulse-Eight after coming fifth in 2024 to return to the team he competed for in the Ginetta Junior Championship, and Flynn Jackes, who joins Elite after finishing the 2024 season in 21st competing for Chris Dittmann Racing. Bianca Bustamante, who spent 2024 racing in F1 Academy, where she finished seventh with ART Grand Prix, completed Elite's lineup.
JHR Developments downsized from three to two entries after John Bennett stepped up to Formula 2 with Van Amersfoort Racing, Patrick Heuzenroeder joined Xcel Motorsport and Josh Irfan left the series. The team signed Kai Daryanani, who stepped up to GB3 after competing in six different Formula 4 series in 2024 and winning the Formula Trophy UAE driving for Evans GP, and Noah Lisle, who returned to the team he drove for in the 2022 F4 British Championship after spending 2024 driving for Campos Racing in Eurocup-3, where he finished twelfth in the standings.
VRD saw Nikita Johnson switch to Hitech GP, while Shawn Rashid joined Nielsen Racing in Euroformula Open and Noah Ping also left the series. The team signed Red Bull junior Enzo Tarnvanichkul, who contested the opening round of the season as well as rounds five to eight alongside his main Eurocup-3 campaign with Campos Racing.

Fortec Motorsport also renewed their lineup after Edward Pearson moved to Nielsen Racing in Euroformula Open, Colin Queen joined Ansa Motorsport in Lamborghini Super Trofeo North America and the team's two part-time competitors of 2024 did not return.

None of Chris Dittmann Racing's seven one- or two-race entries of 2024 returned to the team for 2025, while Flynn Jackes moved to Elite Motorsport and Sebastian Murray joined Indy NXT with Andretti Cape Indy NXT. The team entered 2025 without any confirmed full-time entries, as Formula Trophy UAE runner-up Rashid Al Dhaheri was only slated to drive for the team at selected rounds that do not clash with his FRECA commitments and Indian F4 graduate Divy Nandan was initially only confirmed to race for the team for the opening round.
Hillspeed's only full-time driver of 2024, Aditya Kulkarni, left the team and the series. The team entered 2025 with three FRECA drivers coupling their main campaigns with the GB3 events at Silverstone in April and Spa: 2024 Italian F4 champion Freddie Slater, who made his GB3 debut during the penultimate round of 2024 driving for Rodin Motorsport, Kanato Le, who made his GB3 debut for one round in 2024 driving for Chris Dittmann Racing, and Hiyu Yamakoshi, who finished 3rd in the 2024 Italian F4 Championship with Van Amersfoort Racing.
New team Argenti with Prema signed two British F4 graduates in Reza Seewooruthun, who came third driving for Hitech Pulse-Eight, and Mercedes junior Yuanpu Cui, who finished the 2024 season in ninth competing for Argenti's Phinsys-branded outfit. Lucas Fluxá, who graduated from Spanish F4 after finishing eighth with KCL by MP Motorsport in 2024, completed the team's lineup.
New team Xcel Motorsport signed a returnee and a debutant in Patrick Heuzenroeder, who embarked on his second season in the championship after finishing the 2024 season in twelfth driving for JHR Developments, and Jack Sherwood, who graduated from British F4 after coming fifth in 2024 with Rodin Motorsport and made a one-off appearance in the 2023 season for Chris Dittmann Racing. The team's lineup was completed by Dion Gowda, who debuted in GB3 with a part-time campaign comprising the first round at Silverstone as well as the round at Spa alongside his main FRECA campaign.
Mid-season Chris Dittmann Racing did not enter cars at the second round, with Divy Nandan electing to move over to JHR Developments. Fortec's Mika Abrahams meanwhile left the championship.
Hitech's Nikita Johnson left the series ahead of the event at the Hungaroring due to conflicting commitments in FIA F3, while Fortec's Stefan Bostandijev also stepped away from GB3 and Divy Nandan also missed round four.
Three US-based drivers made their European racing debuts in round five: Chris Dittmann Racing returned to the series by fielding USF Juniors driver Rodrigo Gonzalez and FR Americas competitor Nicolas Stati, while VRD signed Rodrigo's brother Patricio, who also competed in USF Juniors, for the remainder of the season. Euroformula Open drivers Michael Shin and Yevan David also entered round five, driving for Hillspeed and Xcel Motorsport respectively. The former returned to the series after last racing there in 2023, whereas David debuted in the championship. British F4 driver August Raber made his GB3 debut driving for Argenti with Prema, replacing Yuanpu Cui, who joined Hillspeed.
None of the one-off drivers from round five returned for round six, apart from Rodrigo González, who moved over to join his brother at VRD for the rest of the season. Nikita Johnson meanwhile returned to Hitech after a two-round absence, while Divy Nandan and Yuanpu Cui both ended their campaigns early.
Ahead of the round at Donington Park, Lucas Fluxá announced he would follow Yuanpu Cui in leaving Argenti with Prema to join Hillspeed for the rest of the year. Three drivers made their GB3 debuts in round seven: Formula 4 driver Bart Harrison piloted a third car for JHR Developments, Alpine Academy driver Kabir Anurag joined Xcel Motorsport and USF2000 race winner Liam McNeilly debuted with Fortec Motorsport on the team's return after not fielding any cars after round three. The round at Donington also saw the debut of a new team, with GT racing team Racelab making their single-seater debut by fielding series returnee Max Taylor. Elite Motorsport's William Macintyre announced ahead of the round that he would temporarily step back from motorsport due to a cancer diagnosis.
McNeilly and Taylor departed GB3 after their single-round outings as the final round saw three more debutants and a returnee: Formula 4 drivers Maxim Rehm and Newman Chi joined Hillspeed, while Elite Motorsport promoted GB4 runner-up Isaac Phelps to their GB3 outfit and August Raber returned to Argenti with Prema.
Race calendar The race calendar was announced on 22 August 2024. The series continued its evolution from a British-focused calendar towards racing all over Europe. It added another event outside the United Kingdom with the championship making its debut at Monza, and dropped Oulton Park from the list of its venues.
