We’re on a high-speed taxi ride with teenage sensation Kimi Antonelli as he takes series co-host Holly Samos on a thrilling hot lap around Silverstone, home of the British Grand Prix. The 18-year-old’s career is also hitting the gas, after Mercedes chose him to replace seven-time Formula 1 World Champion Lewis Hamilton and handed the Italian his F1 debut in 2025.

Already a social media sensation, Britain’s Ollie Bearman is also finding his feet in F1 and co-host Sarah Holt joins him in the passenger seat at the Goodwood Festival of Speed, a summer highlight on the British motorsport calendar. When it comes to life as an F1 driver, the 20-year-old Haas driver is still adapting to being in the spotlight during his rookie season.

It’s not only fresh, young drivers who are driving F1 into the future, the Cadillac Formula 1 team are also preparing to join the grid in 2026, when major new technical rules are set to shake-up the sport. On a sprawling industrial estate - just metres from the Silverstone circuit - Sarah and Holly are taking an exclusive first look at the team’s F1 factory.

But founding an F1 team - even with backing from U.S. car giant General Motors - is a huge undertaking, as Cadillac team principal Graeme Lowdon reveals in this episode.
