The Formula 1 world is completely upside down after Max Verstappen’s explosive performance. The three-time world champion hinted in the paddock that McLaren is using a technical secret that may be contrary to regulations.

According to sources within Red Bull, the team has officially filed a complaint with the FIA. Verstappen himself called it “unbelievable what’s happening” and hinted that McLaren’s recent speed gains weren’t just due to talent and strategy.

The FIA has now confirmed that a full inspection is underway on McLaren cars. Particular attention will be paid to aerodynamic parts and potential systems that fall outside the rules. “If illegal construction is found, sanctions will follow,” a spokesperson said.

Fans are divided. Some praise Verstappen for his openness and courage in raising the issue, while others believe Red Bull is trying to pressure a competitor who is getting dangerously close.

How this plays out further could have huge consequences for the championship. One thing is certain: Verstappen’s performance has only heightened the tension in Formula 1.
