EXPLAINED: Everything you need to know about the Spanish Grand Prix front wing Technical Directive

Formula 1’s governing body, the FIA, is set to impose tougher load tests on front wings starting from the upcoming Spanish Grand Prix. This move addresses long-standing concerns that some teams might be exploiting flexible wing designs to gain aerodynamic advantages, such as reducing drag at high speeds or altering the car's balance. Concerns emerged throughout the 2024 season, prompting the FIA to install cameras on front wings from the Belgian Grand Prix onwards. While these observations confirmed the need for stricter regulations, the decision to implement them mid-2025 was made to avoid undue burden and expense on teams, allowing them time to adapt rather than scrapping existing components. The new regulations, detailed in Articles 3.15.4 and 3.15.5 of the 2025 Technical Regulations, significantly reduce the permissible vertical deflection of front wings under load. For symmetrical loads, deflection is now limited to 10mm (down from 15mm), and for one-sided loads, 15mm (down from 20mm). Additionally, front wing flap deflection is tightened from 5mm to just 3mm. These tests will be conducted regularly, including during parc fermé conditions, to ensure compliance.
