Championship leader Oscar Piastri will be hoping to widen the gap ahead of team-mate Lando Norris and reigning champion Max Verstappen in the drivers' standings as the competition heats up following a new technical directive introduced this weekend.
The Spanish GP not only marks the end of the European triple-header where so far only Verstappen and Norris have stood on the top step of the podium, but it also introduces new flexi-wing rules from F1's governing body.
The clampdown on flexi-wings sees the allowance reduced from 15mm to 10mm on the front wing and its flap on every F1 car, with many expecting McLaren to take the biggest hit on their strong form which has so far seen them dominate the constructors' championship in 2025.
Qualifying sets the order for Sunday's Spanish GP but only the main race will truly show whether the papaya outfit have been hampered by the change or if they can continue their strong form across the remainder of the campaign.
