The GB4 Championship is back for its fourth season in 2025, boasting a new car and its largest grid to date. Feeder Series tells you everything you need to know about the British-based series ahead of its 2025 season.

By George Sanderson

Twenty-one drivers took part in at least one round of the 2024 GB4 season, but only 11 completed the full calendar. One of those was eventual champion Linus Granfors, who secured six wins and four further podiums for Fortec Motorsport. Despite his success, the Swede has not announced 2025 racing plans.

For this season, the grid has grown substantially. Twenty-four drivers have already been confirmed, eclipsing the grid of 14 drivers from the start of last season, with four more seats still to be filled before the grid reaches capacity.

A large factor in this increase is the revitalised car for 2025. The Tatuus MSV GB4-025 has been introduced for this season and is a scaled-back version of the car used in the GB3 Championship for the past three years. The introduction of the halo heralds a major step forward in safety, while lower-downforce, single-plane front and rear wings have been brought in to improve aerodynamic performance.

Drivers will compete to win the title and earn a £50,000 contribution towards a campaign in the 2026 GB3 Championship. A £50,000 contribution is also available to the leading female driver to be used to fund a seat in F1 Academy in 2026. This amount has increased from the £30,000 given last year to Elite Motorsport’s Alisha Palmowski, now at Campos Racing in the all-female series.

The calendar

The 2025 GB4 calendar consists of seven rounds at all of the same circuits as last year. Whilst senior series GB3 ventures off into mainland Europe for four of its eight rounds, GB4 remains a wholly UK-based championship as a way of keeping costs down for competitors. In six of the seven rounds, GB4 continues in its support role to British GT, with the only exception being a co-headlined round with GB3 at Silverstone in August.

There are some changes in structure to this season’s calendar. After two years as season opener, Oulton Park has been replaced by Donington Park, with GB4 starting its season three weeks before GB3 does. It is the first time since 2022 that the championships have begun their seasons on different dates.

Donington Park also becomes the season finale, replacing Brands Hatch. The 2025 season thus ends a week later than in 2024, and two weeks before the GB3 finale in Monza. Along with Donington, Silverstone is the only other venue to feature twice on the calendar.

• Round 1: Donington Park GP (5–6 April)
• Round 2: Silverstone GP (26–27 April)
• Round 3: Oulton Park International (24–26 May)
• Round 4: Snetterton 300 (12–13 July)
• Round 5: Silverstone GP (2–3 August)
• Round 6: Brands Hatch GP (23–24 August)
• Round 7: Donington Park GP (4–5 October)

The format

The format for the 2025 GB4 Championship is identical to that of 2024. At all rounds except one, teams are given the Thursday and Friday leading into the race weekend as testing time. Only the Friday is available at Brands Hatch, with testing only being on the shorter Indy circuit.

Each race weekend features a 15-minute qualifying session, followed by three 18-minute races. The grid for race one is determined by each driver’s fastest lap in qualifying, with the grid for race two based off of their second-fastest laps. The top 12 drivers from qualifying are reversed on the grid for the final race of the weekend.

Points are awarded to the top 20 drivers in races one and two, with 35 points for a win all the way down to a single point for 20th. For the reverse-grid race three, only the top 15 drivers score points, with 20 points for victory down to one point for 15th.

In race three, drivers are also awarded points for the positions they gain. If, for example, a driver wins from sixth on the grid, they will earn a total of 25 points – 20 for the win and five for the positions they gained.

Where to watch

All races will be available to watch on the MSV TV YouTube channel and include pre-race build-up and post-race analysis segments. The stream will also be shown on the GB4 Facebook page and website. Pre-weekend test sessions and qualifying are not streamed live. Live timing for all sessions is available through TSL Timing and the GB4 website.

Teams and drivers

KMR Sport

KMR Sport have yet to be beaten in the GB4 Championship, securing their third consecutive teams’ championship in 2024. Led by team principal Kevin Mills, whose full name the team previously bore, they will line up with three new drivers in 2025.

Megan Bruce (#9) returns to the GB4 grid this year, making the move from Fox Motorsport. The 20-year-old Briton had a strong first single-seater campaign last season, finishing every race. She also finished in the top 10 on nine occasions, with a best result of sixth, and scored 183 points.

KMR Sport line up with two female drivers this season, having also confirmed Lily-May Watkins (#15) for 2025. It is the first time this has happened at any GB4 team since Graham Brunton Racing had Logan Hannah and Chloe Grant in their 2022 roster. Watkins, 17 and from Hertfordshire, will contest her first season in single-seaters after having completed a testing programme with the previous generation of GB4 cars at the end of last year.

The final seat at the reigning teams’ champions has gone to Alex O’Grady (#3), who became the 20th driver confirmed on this season’s grid. The 16-year-old Irishman made his single-seater debut last year in the French F4 Championship but missed most test days throughout the season. Nonetheless, he picked up two podiums and 11 top-10 finishes on his way to 12^th place in the drivers’ standings.

Fortec Motorsport

Fortec Motorsport were runners-up in the teams’ championship last season but guided Linus Granfors to the drivers’ title with six victories to his name. The renowned British outfit have three drivers lined up for 2025.

Jack Taylor (#50) remains with the team for a second season following an impressive debut season in GB4. The Australian secured 13 top-10 finishes last season, including a podium at Silverstone, on his way to a ninth-place finish in the standings. He also finished eighth in the 2023 Indian F4 Championship.

British driver Thomas Ingram Hill (#8) makes his single-seater debut this season in his second full year of car racing. The 15-year-old competed in the Ginetta Junior Championship last year, finishing 11^th in the drivers’ standings, and said he felt he was “relearning everything” in testing as he adapted to open-wheel racing.

Fortec Motorsport complete their line-up with the signing of Luca Magnussen (#23), another single-seater debutant. The Dane comes from a family with a rich racing history, as both his father Jan and half-brother Kevin have raced in Formula 1. The 15-year-old has driven karts since the age of six and recently represented his country in the Karting Sprint Senior category of the FIA Motorsport Games.

Elite Motorsport

Elite Motorsport finished just 22 points behind Fortec Motorsport last season and were runners-up in the drivers’ standings with Alisha Palmowski. The striking yellow liveries will be expected to appear at the front once again in 2025 as the team return with a three-driver line-up.

Team principal Eddie Ives’ first signing for the 2025 season was Alexandros Kattoulas (#51). The 19-year-old, who grew up in Singapore but is now based in Nottingham, contested the seventh round of last season’s GB3 Championship. This gave him valuable experience in the Tatuus MSV-022, which has since been modified for use in GB4 this year. He was also fastest on two testing days leading up to this season.

Alongside Kattoulas will be Ary Bansal (#46), who made his single-seater debut last November when he took part in the final round of the Spanish F4 Championship. The 15-year-old raced for Rodin Motorsport at Catalunya, picking up a best finish of 19^th. He also represented Xcel Motorsport in the end-of-year 2024 Formula Trophy UAE season, finishing 14th in the standings. A resident of Bangalore, Bansal began karting in India back in 2021 before plying his trade in British Karting Championship events for the past two years.

British driver Isaac Phelps (#35) completes Elite Motorsport’s line-up for this season. Another 15-year-old, Phelps was the second-highest-placed rookie in the Ginetta Junior Championship last year, finishing fifth in the overall standings with three wins and five further podiums to his name. Phelps was second quickest on both Snetterton test days and topped the times on the first test day at Donington.

Fox Motorsport

Fox Motorsport have finished fourth in the teams’ standings in both of their GB4 campaigns since making their debut in single-seaters in the championship in 2023. Last season saw the race-winning GT team pick up a total of six podiums in GB4, winning one outright thanks to Branden Templeton at Donington Park.

So far, the team only have Holly Miall (#48) confirmed for the 2025 season, though at least one more driver is expected to join her. Chelmsford’s Miall embarks on her third season with Fox Motorsport, having represented them in their Ginetta Junior efforts for the past two years. This season will be the 17-year-old’s first in single-seaters.

Caitlyn McDaniel completed a number of test days with Fox Motorsport over the winter. The 17-year-old American got her first experience in single-seaters back in December, when she tested the previous-generation GB4 car at Snetterton. In January 2025, she tested the 2025 model for the first time, again at Snetterton, before taking part in further private tests at Donington, Oulton Park and Silverstone. McDaniel hasn’t been confirmed for a 2025 seat, but given her appearances at the official Donington Park and Silverstone tests, there may be a view to this during this season.

Graham Brunton Racing

GBR have been a constant feature on the GB4 grid since the series’ creation in 2022. The Knockhill-based team return this season along with both of their Canadian drivers who started last season.

Callum Baxter (#45) returns to the grid having finished seventh in a full 2024 campaign with GBR. The 18-year-old finished in the points 18 times last season, also earning himself a podium at both Donington Park and Snetterton. Previously, he finished second in Canada’s F1600 series in 2023 and enjoyed an illustrious karting career in which he won numerous titles between 2017 and 2021 while competing in Canada, the United States of America and Bahrain.

Mayer Deonarine (#44) only took part in the first three events of the 2024 season, which were his first in single-seaters, because of a lack of funding. This time around, however, he returns to GBR for the full 2025 season. The 16-year-old, like Baxter, is supported by the Road to Racing Canada organisation, and he impressed with four top-10 finishes in his nine GB4 races last season. His first car racing experience came in March 2024 in the Radical North America Cup, in which he became the youngest podium finisher in the series’ history at the age of 14 years, 11 months and 24 days.

Alex Berg (#98) is the third and final driver on the books for GBR this season, completing an all-Canadian line-up. The 18-year-old son of former F1 driver Allen Berg has scored one race win in both the United States and British F4 championships, coming at New Jersey Motorsports Park in 2023 and Thruxton in 2024 respectively. He finished those seasons seventh and 14th in the drivers’ standings, while he finished fifth in his debut year in F4 US in 2022. In 2021 and 2022, he also competed in the Spec MX-5 Challenge Series, finishing third overall and winning the South Region title in 2022. Berg also partly runs the Berg Racing Ligier Junior Formula Championship team.

Arden Motorsport

Arden Motorsport returns to GB4 after having made their debut in the championship last season. The Banbury-based team were formed by Red Bull team principal Christian Horner and his father Garry Horner back in 1997 and have experience across multiple levels of the feeder series ladder, nurturing the growth of names such as Oscar Piastri, Sergio Perez, Carlos Sainz and Pierre Gasly.

They currently have two drivers confirmed for this season, the first of those being the returning Leon Wilson (#27). The 17-year-old Yorkshireman finished 10th in the standings in his debut car racing season. A podium at Silverstone in his fifth race was a season highlight, but 11 further top-10 finishes, including six on the bounce to end the season, also showed solid consistency.

American teenager Ava Dobson (#55) will partner Wilson this season. The 16-year-old from Milwaukee took part in the second Silverstone and Donington Park rounds last season, with a best finish of ninth place. Dobson was supposed to run a full season in the 2024 USF Juniors Championship, but a high-speed collision with a stationary car at Barber Motorsports Park left her sidelined with injuries to her chest, back and left hand.

Rossoverde Scorpio Racing

Rossoverde Racing and Scorpio Motorsport have continued their partnership, which dates back to a 2018 British F4 round at Silverstone, by entering GB4 as a joint venture for 2025. In previous seasons, Rossoverde have only ever fielded Christian Lester, who has only raced at a single GB4 round in each of the last two years. Scorpio Racing have not featured on a GB4 grid since Aqil Alibhai took part in the 2022 finale at Donington Park.

Instead of Lester, however, the team will field Neirin Evans (#64), who is making his debut in car racing this season. Having begun his karting career at the age of 13, Evans raced nationally in the UK in 2022 and 2023, reaching the Easykart world finals at Franciacorta in 2023. The 16-year-old Welshman is part of the Young Racing Driver Academy (YRDA), the alumni of which includes current F1 driver Oscar Piastri.

ADM

ADM announced in November that they would be joining the GB4 Championship for the 2025 season, with plans for a two-car entry. So far, only one driver has currently been confirmed.

Jason Pribyl (#59) makes the move to GB4 after finishing as runner-up in the United Formula Ford Championship last year. The 19-year-old from the Chicago area took two victories, one of which came in his debut race, and five further podiums. Pribyl was runner-up in the northern region of the SCCA’s 2023 Spec Racer Ford Gen3 category and was also the 2021 Formula Enterprise 2 champion. He previously tested USF2000 machinery in 2022 and 2023.

Douglas Motorsport

Douglas Motorsport have totalled 20 race victories and more than 80 podiums in the GB3 Championship, formerly British F3 and BRDC F4, across 11 seasons. After having tested but not raced in 2024, the team will expand into GB4 with a three-driver line-up.

Single-seater newcomer Luke Hilton (#32) was their first confirmed driver. The Essex-born 17-year-old began car racing in 2023 in the Fiesta Junior Championship, in which he racked up four wins, five total podiums, three pole positions and four fastest laps. Those results put Hilton sixth in the championship, and he then took on the Radical Cup UK and Gulf Radical Cup in 2024, achieving a win and seven further podiums in the former and two wins and another podium in the latter. In the final GB4 pre-season test, Hilton ended both days at Silverstone quickest, making him an early favourite to contend for the title.

Dayton Coulthard (#28), the son of former F1 driver David, was the second driver to be confirmed for Douglas. The 16-year-old Scotsman, born in Brussels, began competitive karting in 2019 and ended his 2024 karting exploits with victory at a two-day Whilton Mill event to win the WM Plate trophy. Coulthard is a Red Bull athlete and the third son of an ex-F1 driver to make the 2025 GB4 grid.

The final driver to be confirmed was Enzo Hallman (#7). The Swede finished as runner-up in Formula Nordic in 2024 with five class wins and 11 total podiums to his name. He also finished third in the NXT Gen Cup last year, with nine podiums in 13 races, but never graced the top step of the podium.

Hillspeed

Having won titles in previous years at the FRenault and Ginetta Junior level in the early 2010s, Hillspeed hope to take another on their full-time return to the GB4 grid after last competing in 2022. The Derbyshire-based team have two confirmed drivers so far and are offering a fully funded test in their GB3 car to their highest-placed driver at the end of this season.

The first driver confirmed was former Mercedes junior Daniel Guinchard (#49), who returns to full-time single-seater racing after having to step away in July 2023 because of budget restrictions. The 18-year-old from London took victory at Oulton Park in his debut British F4 season back in 2022 and secured five further podiums across the season. These results earned him ninth in the standings in a grid that contained current F2 driver Alex Dunne and current F3 drivers Ugo Ugochukwu and Louis Sharp. In 2023 he remained in British F4, taking three podiums before budget restrictions forced him to curtail his season after six rounds.

Leandro Juncos (#77) was confirmed as the second Hillspeed driver for 2025, having tested in GB3 with Chris Dittmann Racing for much of the winter. The 19-year-old American raced a partial season in USF Juniors last year, with a best finish of fourth in the second race at Barber Motorsports Park. Juncos has experience outside the cockpit too, having been assistant race strategist for Agustín Canapino and Conor Daly at Juncos Hollinger Racing, the IndyCar team his father Ricardo Juncos co-owns.

Pace Performance

Pace Performance move into single-seater racing for the first time in their history following their maiden campaign in the 2024 Ginetta Junior Championship. Former F2 driver and current Kondō Super Formula driver Zak O’Sullivan tested the team’s car during pre-season. The 2021 GB3 champion, an avid graphic designer outside of motorsport and a longtime affiliate of team partner Kokoro Performance, was also responsible for designing the team’s livery this season.

Josh McLean (#76) was the first driver to be confirmed for Pace Performance this season. His karting career began back in 2015, and he won multiple national titles before halting his career in 2019. The 20-year-old Briton makes his single-seater debut this season but already has experience working with Pace, having raced for them in three Ginetta GT Championship races at Donington Park last year.

Stefan Bostandjiev (#17) makes his single-seater debut in the opening round at Donington Park, having competed in sports cars for the past four years. The 20-year-old Bulgarian is combining his full-time GB3 commitments with Fortec Motorsport with a part-campaign in GB4 with Pace Performance. Bostandjiev spent 2021 through 2023 in ADAC GT4 Germany, achieving two podiums in his debut season. In 2024, he moved to the Lamborghini Super Trofeo Europe, scoring two podiums and finishing seventh in the standings in the Pro class.
