Scuderia Ferrari has reportedly asked the Fédération Internationale de l’Automobile (FIA) for clarification regarding the legality of Mercedes AMG Petronas Formula 1 Team’s front-wing system following the Chinese Grand Prix.
According to a report from Rosario Giuliana of the Italian outlet AutoRacer, Ferrari raised questions with F1’s governing body after technical analyses suggested Mercedes may be using a sophisticated two-phase front-wing closing mechanism.

The discussion centers around how the front wing transitions between its open and closed positions during braking (active aero closing). The inquiry adds to a growing list of technical discussions between teams and the FIA this season, including earlier debates surrounding Mercedes’ engine compression ratio.
Under current regulations, sensors monitor the timing of this movement to ensure the wing closes within the permitted limits. However, analysis of onboard footage and technical data from the Shanghai weekend reportedly suggested that the Mercedes system may operate differently.
Ferrari Questions Mercedes’ Two-Phase Wing Mechanism
According to the report, the Mercedes wing may complete its movement in two separate phases rather than a single continuous motion.
The first phase reportedly occurs within roughly 400 milliseconds, which is the window that FIA monitoring systems detect as a completed closing action. A slower second phase then completes the movement, allowing the wing to reach its final aerodynamic position after the sensors have already registered the closure.

If accurate, the design could allow the wing to technically comply with FIA timing limits while still achieving its intended aerodynamic configuration. Ferrari has therefore requested clarification from the FIA to determine whether the system complies with Formula 1’s technical regulations.

At this stage, the FIA has not officially announced a ruling or investigation regarding the front-wing system used by Mercedes.
The development comes shortly after Mercedes enjoyed a strong Chinese Grand Prix weekend, in which Kimi Antonelli secured a historic victory and George Russell finished second, giving the team a dominant one-two result in Shanghai.
Mercedes Compression Ratio Debate
The front-wing discussion is not the first time Mercedes has been at the center of a technical debate this season.
Previously, many drivers and teams, including Lewis Hamilton, raised questions with the FIA regarding the engine compression ratio used by Mercedes, prompting discussions about whether the team’s power unit configuration complied with Formula 1’s technical framework.

While no rule breach was ultimately confirmed, the inquiry highlighted how closely teams monitor each other’s technical solutions in the early stages of a season. Such exchanges are a common part of Formula 1’s competitive landscape, where even minor innovations can prompt rivals to seek clarification from the governing body.
For now, Ferrari’s request regarding the Mercedes front-wing system remains a technical inquiry rather than a formal protest. Whether the FIA chooses to issue additional clarification or review the design more closely could become clearer in the coming race weekends.
As the 2026 F1 season continues, rival teams will likely keep a close watch on Mercedes’ aerodynamic solutions, particularly after the team’s strong performance in Shanghai reignited competition at the front of the grid heading into the Japanese Grand Prix.
