GB3, British F4 and Euroformula Open all get their 2025 seasons underway this weekend as GB4 holds its second round at Silverstone. Keep reading to find out what to watch for and how to keep up with them.

The junior single-seater spotlight this weekend falls on Great Britain, where GB3’s new car will make its debut at Silverstone as GB4 holds its second round with its senior series’ former car. Just over an hour’s drive to the north, British F4 also launches its 2025 season at Donington Park, meaning all three British junior single-seater championships will race on the same weekend for the first of two times this year.
There is activity in Southern Europe as well, with Euroformula Open taking to Portimão for its own first race with a new car, the Dallara 324. The series, which now races with a spec engine, features its largest grid in three years. The Hoosier Formula Cup, meanwhile, heads to Monza for its second round.
A former F4 series also returns for its second season with a mix of young Nordic talents and gentleman drivers on the grid. Nordic 4, previously Danish F4, begins at Padborg Park this weekend with its first solo round before it joins up with the new Nordic Championship Formula series and Sweden’s Formula Nordic for a number of shared events. Last year’s rookie champion Sebastian Bach and 2023 runner-up Magnus Pedersen are among the overall title favourites, while reigning F5 champion Mads Hoe is a favourite in his class once again in 2025.

What to know: A new season of the GB3 Championship begins this weekend, bringing with it a new car, a new venue for the opening round of the season and a host of new drivers and teams. A grid of 24 drivers is expected to take to the track for the first of eight rounds in 2025.
The battle at the front is set to be extremely tight, with multiple teams and drivers having topped the times at various testing days. Hillspeed’s Freddie Slater, Hitech’s Deagen Fairclough and Xcel Motorsport’s Patrick Heuzenroeder appear to be the early favourites, but drivers from Rodin Motorsport and Argenti with Prema should not be ruled out. Former F1 Academy drivers Abbi Pulling and Bianca Bustamante will also be ones to watch, with Pulling finishing five of the seven official pre-season tests inside the top 10.

What to know: GB4 heads to Silverstone for the second round of 2025. A record-breaking grid of 25 drivers competed three weeks ago at Donington Park, with just 1.007 seconds separating the top 19 in qualifying.
Despite not winning a race in round one, Hillspeed’s Daniel Guinchard currently leads the championship with 66 points ahead of Elite Motorsport’s Isaac Phelps on 64 and Alexandros Kattoulas on 58. Phelps took an impressive double pole at Donington, converting it into victory in race one and second behind teammate Ary Bansal in race two.
With Kattoulas third in race two, Elite became the first team to lock out the podium in GB4. They also lead the teams’ championship on 149 points, 39 points ahead of Hillspeed and 63 ahead of Douglas Motorsport in third.
Everyone from round one will return for round two except for Stefan Bostandjiev, who begins his regular campaign in GB3.

What to know: Widely regarded as the effective successor to European F3 at least in terms of machinery, the Euroformula Open Championship will return for a 25th season with a new car and team featuring on the grid. Continuing the trend of using upgraded versions of the Dallara F312, the championship will switch to the Dallara 324 chassis, also used in Super Formula Lights.
The chassis isn’t the only new element for this season, as sports car veterans Nielsen Racing will embark on their maiden foray in single-seaters with a three-car line-up.
Meanwhile, six-time teams’ champions Motopark return with a six-car line-up headlined by Sri Lanka’s Yevan David, who took a surprise debut win last season at Monza. Also returning are BVM Racing, who sport a brand new two-car lineup consisting of Tymek Kucharczyk and Vladislav Ryabov. Get to know the rest of the grid by reading our season guide.
Report by Marco Albertini
From the press: As BVM Racing’s sole driver until this year, Francesco Simonazzi became a staple of the Euroformula Open grid, battling and often defeating the multi-car Motopark behemoth. As he takes on a new role as the team’s development driver for 2025, he sat down with Feeder Series to reflect on his tenure in Euroformula Open. Read the article here.

Weather forecast: Cloudy all weekend, with some sunny spells on Sunday. There is a moderate chance of light rain on Saturday afternoon.
What to know: British F4 returns for its 11th season this weekend at Donington Park. The gap between returnees and rookies seems to have narrowed significantly, promising a much closer battle up top this year than in 2024.
Twenty drivers race this weekend, with experienced drivers such as Hitech’s Leo Robinson and 2024 rookie champion Martin Molnár hoping to build an early advantage as the newcomers find their feet. Among them, Red Bull junior Fionn McLaughlin and Mercedes junior Ethan Jeff-Hall both showed strong pace throughout testing.
The series also introduces a new Challenge Cup class for drivers competing in seven or fewer rounds of the overall championship. Within that class, McLaren development driver Ella Lloyd will look to use her knowledge of British circuits to better fellow F1 Academy driver Alba Larsen.
Learn more about the grid and weekend format by reading our 2025 season guide, to be released later today, and follow British F4 editor Gavin on X for updates from the Donington Park paddock this weekend.

Dear Feeder Series. I am always very happy that you publish the info about the Formula 4 and other equal series.
But a question? Why is the races at Padborg for the Nordic/Danish Formula 4 and 5 series not published?
LikeLike
Great question.
Our decision not to write round-by-round reports for them had several factors. The primary consideration was that our audience simply didn’t show the interest over time to make doing so a worthwhile endeavour. Over the years, Formula Nordic in particular has produced vanishingly few drivers who have moved upwards or sideways on feeder series ladder – many of its competitors are privateers who remain within the Nordic scene long-term, and the same is increasingly becoming true of Nordic 4’s grid. It’s understandable that people aren’t all that interested when the series’ relevance to the broader single-seater landscape has dwindled.
Additionally, the fact the series race jointly sometimes and separately at other times does not lend itself well to the kinds of race reports and previews we publish. And races without any kind of livestream or trackside broadcast, as is the case with a number of Nordic 4 and Formula Nordic events, are considerably harder to cover with the accuracy our readers deserve.
We’re certainly open to adding them if the circumstances are right and if there’s sustained demand for them.
