We open Episode Five checking in at the airport with Haas driver Ollie Bearman as he prepares to take off for the final three races of the 2025 Formula 1 World Championship. But there’s only one thing on his mind - will he get the dreaded middle seat?

Fellow rookie Kimi Antonelli is also flying high as Formula 1 touches down for the Las Vegas Grand Prix. The Mercedes teenager takes a gamble on tyre strategy but will it pay off when the cars hit The Strip? Antonelli and his race engineer Pete Bonnington are looking back on the teenager’s rookie season in 2025. Bonnington, aka Bono, was one half of F1’s most successful driver-engineer pairing with seven-time World Champion Sir Lewis Hamilton, so how does it compare working with a rookie making his first steps into F1?

While the competition is nearly over on track, the race inside the team’s top-secret F1 factories has only just begun. It’s early December, and all the teams are pushing
hard to build a completely reimagined car for F1’s new era, when a new set of technical regulations are set to shake up the sport. At Mercedes, our F1 experts Sarah Holt and Holly Samos are given a guided tour by Chief Operating Officer Rob Thomas on the factory’s busiest day of the year.

As the sport prepares to move forwards into its new era, the dust is settling on the 2025 season at the finale in Abu Dhabi. There’s time for Bearman and his race engineer Ronan O’Hara to also give their verdict on his rookie season and formulate lessons to take into the British racer’s 2026 campaign. But the clock is ticking on Cadillac’s F1 debut… There are now less than 100 days to go until the US team joins the grid and team principal Graeme Lowdon is beginning to feel the pressure.
