The 2026 rulebook shake-up

In this eight-part series, hosted by actress Rosamund Pike, we’re going behind-the-scenes with next generation stars, Mercedes driver Kimi Antonelli and British Haas hotshot Ollie Bearman, during their rookie Formula 1 seasons in the 2025 World Championship.

We are in the passenger seat with the drivers - and we do mean that literally - following the final races of their maiden campaigns and lifting the lid on driver life away from the track with F1 experts Sarah Holt and Holly Samos as our guides.

Former teammates in junior categories, Antonelli and Bearman, are now simultaneously finding their feet on motorsport’s toughest grid. In this series we hear from the two drivers, and those closest to them, as their journey to the top continues.

From inside the Mercedes team, experienced race engineer Pete Bonnington, aka Bono, reveals how he is guiding Antonelli to follow in the footsteps of his former driver, seven-time World Champion Lewis Hamilton while Driver Development Advisor Gwen Lagrue explains how he spotted the natural talent that convinced Mercedes to sign Italian teenager Antonelli at a young age.

Haas rookie Ollie Bearman already has a huge social media following but the attention directed at an F1 driver is next level. The British racer, who made his F1 debut with Ferrari in 2024 as a stand-in for a sick Carlos Sainz, is feeling a lot of love from the fans as we join him at a special appearance with Haas at the Goodwood Festival of Speed.

The 20-year-old can also count on family support and we hear from his younger brother Thomas, also a promising racer, and how they are deciding just who gets to go on Ollie’s race simulator.

As Bearman continues to bring home the points for Haas in 2025, Haas Head of Strategy and Driver Development Ed Brand and his race engineer Ronan O’Hara explain how Bearman is growing as one of F1’s next generation stars.

But it’s not only the drivers who are driving forward F1’s future - there is also a new team about to enter the top tier of motorsport. The series is also following the start-up Cadillac Formula 1 team as they race to join the grid for the very first time. Their uncharted journey is fraught with jeopardy, but they have unlocked their doors and let us inside.

Fan favourites and former F1 race-winners Valtteri Bottas and Sergio Perez are making their comebacks with Cadillac - and we hear from both of them throughout the series.

Cadillac team principal Graeme Lowdon and Executive Engineering Consultant Pat Symonds explain how the team have had a mountain to climb to make it to the grid in 2026, when major technical regulations, governing how the cars are designed and powered, are also set to shake up the sport.

Hollywood legend Keanu Reeves is following in our tyre tracks as he documents Cadillac’s journey to the grid. The actor is also predicting drama as F1 enters a new era in 2026. We hear from him in an exclusive interview as he anticipates that the “hopes and ambitions” of all the teams up-and-down the grid will be tested by the sport’s new rules.

As one season ends another, fraught with uncertainty like never before, lies just around the corner. In this series, we journey with the Cadillac F1 team and drivers Antonelli and Bearman over the winter as they prepare to go racing in F1’s new era.
