Esteban Ocon and Nico Hulkenberg then took the lead on the medium and hard tires respectively, before Lewis Hamilton finished the first five minutes of the hour-long session being the fastest in 1m34.527s.
But that didn’t last long either as Verstappen – unlike Hamilton using the hardliners at this point – went fastest on his second attempt on a first flight after going off in Turn 1 on his first attempt.
Times continued to drop as drivers completed their first exploratory stints, with several having off-track moments at Turn 1 and Turn 11 at the end of the long twisty straight, struggling for grip on the new surface of Track.
During this period, Nyck de Vries lost the rear of his AlphaTauri and turned around on the long, tight Turn 12 right, after which Carlos Sainz was fastest with a 1m33.823.

Perez, however, couldn’t beat Hulkenberg at this point and put his Red Bull third behind the then-focused Haas as Hulkenberg crashed out at Turn 3 on a third flying lap attempt. on the same set of apps.
Having been only marginally slower than his personal best on his second soft flight, Hulkenberg ran slightly off-line into Turn 3 and quickly lost the rear of his car, flipping over and slamming his right side against the wall and sending debris onto the track. .
As Hulkenberg’s car needed to be recovered with its broken right front wheel, the session was halted for eight minutes.
When FP1 resumed ahead of their final quarter, Verstappen returned to action on the softs and improved the first-place benchmark to 1m30.549s – this time completing his flyer without a moment in the first sector.
Leclerc then moved into second place before being demoted by Sainz a few minutes later which relegated Fernando Alonso to fourth.

As the Ferraris prepared for a third attempt on the softs, the Mercedes cars had finally turned off the mids – Russell wasting a lot of time early on as his team decided to pull out a chunk of development direction deemed too heavy based on his first returns.

Sainz’s soft third race set a personal best just before the end of the session, but that couldn’t get him past Verstappen’s fourth place as Red Bull reverted to hard tires for the final minutes.
Pierre Gasly had a wild moment on the second lap of Turn 3 after catching a big snap in Turn 2 late, but finished sixth for Alpine ahead of Alonso.
