Callum Voisin on becoming 2023 GB3 Champion and Rodin's first-ever FIA F3 winner

British-Swiss racing driver Callum Voisin may only be 18, but already he has an extensive racing portfolio to his name. Born in Geneva, Callum started his karting career in France in 2016, before moving to the UK for school a short while later. With experience in closed wheel and open wheel racing, Callum won the 2023 GB3 Championship and made his FIA Formula 3 debut in 2024 with Rodin Motorsport. 

After taking his first F3 podium at Silverstone, Callum is the most recent Formula 3 Feature Race Winner, taking victory at the iconic Circuit de Spa-Francorchamps ahead of the summer break and becoming Rodin's first ever FIA F3 race winner. 

Silverstone caught up with Callum to talk about his most recent achievement, as well as every success he's had in his racing career to date. 

Living in Monaco in his early years meant Callum was exposed to Formula 1 by watching the Monaco Grand Prix in the late 2000s. It wasn't until a few years later, however, in 2016, that he actually started karting properly. Motorsport was banned in Switzerland following the 1955 Le Mans disaster and was only somewhat lifted in 2015, for head-to-head electric racing only. This meant Callum couldn't actually kart in Switzerland when he was initially starting out. However, he lived so close to the French border, meaning it was relatively easy for Callum to begin his karting career. 

"I don't feel like I missed out on anything," Callum says. "France is quite competitive anyway so it's probably a place I would've ended up even if there was racing in Switzerland.

"I moved to the UK in 2017 for school so my karting career moved too, so it didn't really make a difference." 

When Callum made the move to England, karting was just a hobby, with school being the priority for him, but his move across Europe was definitely not a bad thing for his career. 

"The UK is probably one of the most competitive places and it was nice to be there because, even though I officially live in Switzerland, I still see the UK as my home," he says. "I'm glad I got to grow up there and do most of my karting there, and obviously the start of my car career, too." 

Callum's older brother, Bailey, is also a racing driver, currently competing in the European Le Mans Series, and although their racing categories are very different, Callum and Bailey both spent time in the Ginetta Junior Championship. Despite being older than him, Bailey actually started karting because of Callum, but competed in Ginetta Juniors one year before his younger brother. Callum joined the Championship for the 2021 season. 

"I joined the same team so it was quite an easy introduction," Callum explains. "I'd already seen the team, we already owned the car, so in that sense, there wasn't much to do. 

"We just had to change the pedals and off I went." 

Initially, Callum saw his career also following the sports car route because that's what he and his family knew, and where they had the connections, but halfway through his season in Ginetta Juniors, he began looking at alternative pathways. 

"Trevor Carlin offered me a go in an F4 car which was pretty cool for me," Callum says. "I'd never driven a single seater and it was always my dream to drive a single seater car." 

Callum's opportunity to drive an F4 car went down very well and on his return to Ginettas, he won all three races at Brands Hatch. Two days later, he received another call asking if he wanted to try out the GB3 car. Without question, his answer was yes. 

"That went even better," he says. "When you drive a GB3 car, nothing else will really suffice.

"From there, it was all about trying to get the budget to compete in GB3 for a year." 

Callum spent two years in the GB3 Championship. In his first season with Rodin Motorsport, in 2022, Callum finished P4 in the standings. The following year, he joined Rodin Motorsport once again, and had one very specific goal: to become GB3 Champion. 

Throughout 2023, Callum took 11 trips to the podium, more than any other driver, including two trips to the top step at Brands Hatch and Donington Park. At both Silverstone rounds, Callum finished in P3. By the end of the season, one filled with drama and a very tight Championship battle, Callum topped the standings with a total of 484 points. 

"The whole season led up to that one moment: winning the Championship," Callum says. "With me being a second-year driver, that was the only goal and nothing else would've satisfied me. 

"It was a tricky season and sometimes we weren't quite the fastest, but we were consistent. I'd never won a championship and I really needed to do it to move up and seal myself as a driver. Everybody in F2 and F3 has won something of some sort and you have to be part of that and feel like you deserve to be there." 

Callum has spent a lot of time at Silverstone, either through the GB3 Championship or with the BRDC as a SuperStar, as well as being a finalist in the 2023 Aston Martin Autosport Young Driver Award, and it's a place he loves, quite a lot. 

"Silverstone is one of the best tracks there is," he says. "It's a track I've driven a lot over the past few years, it's got some of the most iconic corners in motorsport and it's got one of the best events ever with the British Grand Prix. 

"The fans are incredible, and obviously being a British driver, they're enthusiastic, which is cool." 

Callum might have raced on his first British Grand Prix race weekend this year, but it's not the first F1 weekend he's attended at Silverstone. He's been lucky enough to witness the event from both sides, as a fan and as a driver. 

"The amount of people on an F1 race weekend, it completely transforms the circuit," Callum says. "I've seen Silverstone as it is, just normally, and you wouldn't realise it's the same track, but it is pretty cool." 

This year's F3 Feature Race at Silverstone came with plenty of drama, and Callum was at the forefront of it. Despite leading the race and crossing the line first, he dropped to P3 after receiving a 10-second time penalty for overtaking outside track limits. However, he still got to experience being on the podium - his first F3 podium - in front of his home crowd, something he'll never forget. 

"My all-time highlight from Silverstone is coming over the line first at the British Grand Prix," he says. 

"I wish to have many, many more." 

Callum's first taste of F3 machinery came as a result of winning the GB3 Championship, with a test included as part of the prize. But unlike any other years, he didn't actually know where he would be racing after winning his GB3 year. Testing was in the bag, but he didn't have the budget for a year in F3 and hadn't officially signed a contract. Callum was considering a range of options, including racing int he USA, heading to sports cars, and of course, F3. 

"Rodin came along and gave me the opportunity to race in F3, the championship I think I deserve to be in, especially after winning GB3," he says. "It's the only one that you want to be in naturally to continue on the path to F1." 

Albeit under their former name, Rodin have a steep history of seeing drivers from their team climb the ranks and reach Formula 1, including Lando Norris, Daniel Ricciardo, and George Russell. And Callum? He wants to be next. 

"Being part of a team and so close with a team like Rodin is amazing," Callum says. "I turn up every time and genuinely feel like I belong there.

"Just knowing they believe in me and they've got the confidence in me to push them forwards, it's an incredible feeling." 

One of Callum's teammates at Rodin, fellow Brit Joseph Loake, was one of his closest rivals in the 2023 GB3 Championship battle. They've been working together this season at Rodin and despite getting along well, there's a healthy, competitive rivalry between them. 

"We acknowledge that we were given a very rare opportunity to race in F3 for a year and we're making the most of it," Callum says. "Working with Joseph has been fun, he's pushed me all the way, he's a fast guy.

"It's a bit sad how fast it's gone, since there's only one round left because we do so much this June to July period and then there's only one left for the season, but I've enjoyed it a huge amount and I hope Joseph would say the same thing." 

After successful races at both Silverstone and Budapest, securing top-10 finishes in each race at both rounds, Callum was headed into the final race prior to the summer break with lots of momentum. An exciting weekend at an iconic circuit lay ahead, and on Friday - F3's Qualifying day - Callum took Pole for Sunday's Feature Race. 

On Saturday, in the Sprint, Callum finished P7, but all eyes were on Sunday's main event. 

Ahead of the race, Callum was focused on completing the task in hand. He knew what was ahead of him and what he could do if he played his cards right. 

"I was in the best seat in the house and I saw it as an insane opportunity to make something happen," he says. "I knew what was at stake, and knowing that I've never won an F3 race, the team have never won an FIA Formula 3 race, so it was just a huge opportunity; I did the hard work on Friday." 

The race was far from plain sailing. Callum had to navigate three Safety Car restarts and in tricky conditions on Spa's long straights, whilek keeping 29 other cars at bay. But, he did what he had to, and he reached the Chequered Flag ahead of the rest of the field, securing his very first FIA Formula 3 race victory. 

"It's the biggest highlight of my career so far," Callum says, proudly. "Winning GB3 was very cool and so amazing but I'd say the F3 win is at least on par, maybe a step above, just because of how it came about.

"It's the team's first FIA F3 win and for the moment, I can say I'm the only driver to win in a Rodin, so it's pretty cool and I'm sure it'll be the first of many.

With an exciting career ahead, Callum would be extremely happy wherever he ends up, like in IndyCar in the States or another single seater category. However, there's one ultimate goal he's racing towards. 

"It's Formula 1," he says. "The easy answer but not an easy target, but if I keep winning, that's the best way of getting there."
