Ferrari questions Mercedes' 'two-phase' front wing design.

      Ferrari has sought clarification from the FIA regarding the controversial behavior of Mercedes' front wing, which competitors feel may not function as the regulations intended. The system, known as a "two-phase" wing, drew attention during the Chinese GP. Italian sources suggest that Ferrari suspects the switch from ‘straight mode’ to ‘cornering mode’ occurs not in one fluid motion but rather in two separate phases.

      While sensors indicate that the movement is within the regulatory limit of 400 milliseconds, Ferrari believes that this may not provide the complete picture. Their concern is that the initial phase of the movement is very quick—sufficient to meet the sensors' requirements—while a subsequent, slower phase finishes the closure beyond what is being monitored. Consequently, the wing may not be entirely closed when the system indicates it is.

      Ferrari's engineers are reported to have thoroughly analyzed the design, utilizing both open-source actuator data and high-resolution images before bringing up the matter. The possible advantage could be seen during braking, where a more gradual transition might enhance weight transfer and improve the balance of the car. The FIA has reportedly stated it will keep a closer eye on the system, with its interpretation likely influencing whether other teams will try to imitate the concept.

      Notably, Mercedes is set to debut a distinct version of the front wing design in Suzuka, which includes a stylized wolf graphic as part of its collaboration with Adidas’ Y-3 sub-label created by Yohji Yamamoto, despite some humorously associating the wolf with team principal Toto Wolff.
