Seven of the 11 Formula 1 teams will field rookie drivers during Friday’s opening practice session at the Circuit de Barcelona-Catalunya. Under current FIA regulations, every team must dedicate two practice sessions per season to drivers who have started no more than two Grands Prix, a mandate designed to bridge the gap between junior series and the F1 grid.
Who are the seven rookies taking the wheel on Friday?
The grid shuffle for the Barcelona practice session features a mix of academy prospects and established junior champions. According to the official team lineups, the following drivers will replace full-time starters:
- Mercedes: Fred Vesti replaces Kimi Antonelli.
- Ferrari: Dino Beganovic steps in for Lewis Hamilton.
- McLaren: 2025 F2 champion Leonardo Fornaroli takes Lando Norris’s seat.
- Red Bull: Ayumu Iwasa drives in place of Isack Hadjar.
- Williams: Luke Browning replaces Alex Albon.
- Audi: Paul Aron takes over for Nico Hulkenberg.
- Cadillac: Colton Herta makes his debut in Sergio Perez’s car.
Why is the Barcelona-Catalunya circuit the preferred testing ground?
The Circuit de Barcelona-Catalunya serves as the primary hub for F1 development, largely because teams have decades of historical data from this venue. Junior drivers frequently compete here during their Formula 2 and Formula 3 careers, providing them with a familiar baseline. For rookies like Leonardo Fornaroli, who has previously tested a 2023-spec McLaren at this track, the venue offers a controlled environment to calibrate their speed against the benchmark times of their full-time teammates.

How do these rookies compare to previous cohorts?
The experience levels among this group vary significantly compared to past rookie practice sessions. Ayumu Iwasa and Luke Browning are seasoned participants in these sessions, with six and five outings respectively, whereas Colton Herta and Leonardo Fornaroli are making their official FP1 debuts. While Browning balances his Williams simulator duties with Super Formula, Herta is transitioning from a successful career in IndyCar, highlighting the diverse pathways current teams are using to evaluate potential talent.
