Oscar Piastri has defended McLaren's rear wing design, asserting that it is legal and has passed all necessary tests, despite scrutiny following his recent victory in Azerbaijan. Footage appeared to show the rear wing flexing at high speeds, potentially reducing drag and enhancing performance, but Piastri emphasized it is not a 'magic bullet' for the team's competitiveness. He acknowledged the increased attention on McLaren as they have recently overtaken Red Bull in the constructors' standings and stated that the wing is not in a 'grey area' of the rules, which generally prohibit moving aerodynamic devices. Piastri currently sits fourth in the championship standings, 91 points behind leader Max Verstappen. The FIA is reviewing data from the Baku Grand Prix amid ongoing debates about flexi-wings in Formula 1, but Piastri remains confident in his team's compliance with regulations.
