Everything that happened in extended, sole Miami GP F1 practice
Ferrari's Charles Leclerc set the fastest time of an extended 90-minute first practice session for the 2026 Miami Formula 1 Grand Prix, where 10 of the 11 teams have declared upgrades.
Most of the session was spent conducting long runs on hard and medium compounds, and evaluating those upgrades, before the field re-emerged on softs for qualifying runs in the final quarter of an hour.
Ferrari looked assured, Leclerc consolidating his advantage on hards to post the session's best time, a 1m 29.310s, on his second push lap on the softest compound.
On hard tyres, Leclerc had been fastest with a time of 1m29.855s, ahead of Mercedes' Kimi Antonelli and the other Ferrari of Lewis Hamilton.
Red Bull's Max Verstappen was second fastest, 0.297s off Leclerc, and the four-time F1 champion looked far more assured than Red Bull team-mate Isaac Hadjar who was ninth, 1.563s off the lead.
McLaren declared numerous performance upgrades and it was an encouraging session for the team, with Oscar Piastri 0.448s off the lead in third and Lando Norris 0.898s off top spot in seventh - though he'd surely have been higher up had he not had to abort a lap to avoid Alex Albon's Williams at the hairpin.
Between them were the two Mercedes: Antonelli fifth overall and George Russell sixth - both just over three quarters of a second off the pace. Antonelli had to step out of the car before enjoying any soft-tyre running due to a power unit issue and Russell was anonymous.
Alpine was again best of the rest with Pierre Gasly eighth fastest, three places ahead of team-mate Franco Colapinto. They were 1.277s and 1.705s off respectively.
Carlos Sainz completed the top 10 for Williams with Albon 12th, the pair separated by under a tenth.
Ollie Bearman was 13th for Haas and his team-mate Esteban Ocon was 16th - between them the two Audis of Gabriel Bortoleto and then Nico Hulkenberg.
Racing Bulls, Cadillac and Aston Martin looked to be the backmarkers, with Liam Lawson the fastest driver out of the six in 17th - setting his best time on mediums.
Aston Martin is the only team without any declared upgrades in Miami. Its running was stymied by a "power issue in the garage", with monitors and telemetry failing to function at the start of the session.
Fernando Alonso and Lance Stroll only managed to turn their first laps 25 minutes into FP1 as a result. They finished 19th and 22nd, respectively, with the whole field covered by 3.649s.
