Is this Porsche’s latest superstar?

Swooping around the outside of Druids at Brands Hatch as part of a sequence of bold moves to ultimately snare the lead is not a particularly common sight in the Porsche Carrera Cup GB. Especially not for a driver in just their second race weekend in the car. After all, Porsche Carrera Cup machinery has a reputation for initially being very tricky for new drivers to adapt to.

But nobody had told Callum Voisin that. The single-seater convert – an FIA Formula 3 race winner and the 2023 GB3 champion – has been on the pace right from the very start, putting in a string of electrifying performances, such as at Brands, to lead the standings by six points after the first three meetings of the season.

The 20-year-old was chosen as the latest Porsche Carrera Cup GB Junior over the winter and, given the manufacturer’s near-perfect record at uncovering future sportscar stars, it was clear all eyes would be on Voisin. And the Century Motorsport driver has so far more than justified his selection. “We tested him late last year before the shootout and we were super impressed by how he was on that day,” recalls Century boss Nathan Freke, whose squad knows a thing or two about sportscar success, including having guided Andrew Rackstraw to last year’s title. “For a first-time driver in a Porsche Carrera Cup car, he was extremely quick – probably one of the fastest we’ve seen. He’s just taken to it very naturally.

“We see year in, year out that year-one drivers struggle to get the maximum out of the car and in year two they come to the fore. Callum seems to have been able to unlock it early on. His driving style is extremely smooth and he’s almost metronomic.”

Those metronomic performances have netted Voisin four wins from the opening six races and he is yet to finish off the podium. While he was confident of getting up to speed quickly, even Voisin is a little surprised by his level of success.

“I knew coming in we would be strong,” he says. “I’ve got a very good team behind me and I had a good test programme and have a good team-mate in Isaac [Phelps, another single-seater graduate who was last year’s GB4 runner-up], who pushed me along so everything seemed to suggest we would be good, but you never know until you hit the track with everyone together.”

However, this is not the first time Voisin has burst onto the scene upon joining a new championship. He made a similarly dramatic entrance to Ginetta Junior back in 2021 before his title bid was derailed after his car was found to have infringed technical regulations. He subsequently made the move to single-seaters and, after winning the GB3 crown with Rodin in his second season, he jumped up to FIA F3 with the squad and was victorious in his first year. Yet Voisin was never able to repeat such heights in his sophomore campaign last year and opted to make a sportscar switch, following in the footsteps of his older brother Bailey, who contested the European Le Mans Series for a couple of seasons.

A similar career move was always likely for the younger Voisin, particularly as he never expected to climb the single-seater ladder. “I made it much further than what we actually thought was possible,” he admits. “I look back on it and I’m super proud of what I’ve been able to do. I knew at some point it was going to have to come to an end but, when you’ve got the opportunity to do it, you’ve got to give it a go. I’m very pleased with how far I was able to go and the move to GTs wasn’t inevitable but was always a very realistic option.”

Voisin describes his new Porsche steed as a “completely different beast” to what he has been used to in recent years. “The transition wasn’t seamless but it went pretty well and I’m still learning and that’s what’s quite exciting,” adds the former Aston Martin Autosport BRDC Award finalist. “I’m still nowhere near where I can be.”

That should be a worrying prospect for his rivals, with Voisin pinpointing his launches as one area that “needs some work”. However, before getting too carried away with his performances, it must be noted that this is not exactly a vintage year for the Carrera Cup GB. Grids last season were not especially abundant and that meant 2026 was always going to be a tricky year for the series with it being the final campaign for the current Type 992 edition of the 911 GT3 Cup car. Prospective drivers and teams were therefore unwilling to commit to purchasing a car with a limited shelf life. “Regardless of how big the field is, at the front it’s always competitive,” says Voisin, with Team Parker second-year Will Jenkins so far proving to be his closest rival. “The Pro category is still quite rich and there’s still a lot of good drivers in there. Regardless of what the grid is, you’ve still got to do the job.”

And that is exactly what Voisin is doing so far as he seeks to emulate Harry King by impressively winning the title in his first season. The Junior programme is a two-year scheme, but Voisin has no interest in taking things steady and is also already looking forward to the new machine’s arrival. “I’ve got two years, but I want to prove myself in the first year,” he states. “Next year we’ve got a new car coming and that will reset everything. I’m excited for that and it will be interesting to see how many people will be turning up.”

Voisin does already have an insight into that new car as he is contesting a dual campaign in the Carrera Cup Italia this season. He has taken a best result of ninth from the sole non-clashing event so far in that series, which made the switch to the latest Porsche a year earlier than the GB division, as he competes for the Ombra Racing squad.

Back in Britain, alongside the guidance of Century, Voisin has also received support from the BRDC SuperStars initiative. He was first selected for the exclusive scheme that aims to support the brightest British prospects in 2023, and credits the advice of programme director Andy Meyrick. “I’m in my fourth year with BRDC SuperStars now,” says Voisin. “Andy has always been very helpful and it’s a highly prestigious programme to be a part of. It’s brilliant – we do training days and camps, so it does help with your development and everybody’s racing drivers and knows what you’re going through. Andy and a lot of other people involved in that programme have done so much and experienced so much and especially over the winter, when I wasn’t 100% sure what I would be doing, it was very helpful to get an insight from them into what a possible trajectory looks like.”

Based on Voisin’s initial Porsche performances, Freke certainly feels his charge is on the trajectory to a blossoming sportscar career. “He’s already doing an amazing job,” concludes Freke. “He’s super professional to work with and a very rounded and polished product and understands what he wants from the car and the team. I think he will go very far. The other thing which has been really good to see is that his racecraft is exceptional. He’s had a couple of races where he’s had to fight a little bit, and his race pace is phenomenal but his racecraft is mega. The Porsche is traditionally very hard to overtake in and he’s enjoyable to watch.”

Voisin is determined to continue entertaining and wants to produce more moves like those moments of Brands brilliance. He is eyeing a possible Porsche Supercup entry next year and longer term has aspirations of being a factory GT3 racer. If he can keep turning heads with his displays, while defying expectations, then he has every chance of doing just that.
