F1 cars must comply by new design rules for their front wings from the 2025 Spanish GP. But why are they needed and what do they mean?

Lando Norris, Oscar Piastri, and other F1 drivers offered their thoughts on the new F1 flexi-wing regulations Thursday at the Spanish Grand Prix

With a 1000N load applied to either side of the front wing, the flex tests only permit a maximum of 10mm of deflection, down from the previous benchmark of 15mm. This has prompted teams to strengthen their wings, although many of those changes will largely remain structural.
