Red Bull’s internal probe into Max Verstappen’s Silverstone crash has prompted the FIA to seek extra data from both Red Bull and Ferrari. The governing body wants to confirm that the teams’ rotating rear wings—known as the Macarena wing—meet all safety requirements, especially the 400 milliseconds transition limit.

Ferrari introduced the first rotating wing during Bahrain pre‑season testing, aiming to cut drag, but chose not to race it until the Miami Grand Prix. Red Bull unveiled its own model in Florida, noting its design rotates opposite to Ferrari’s. The Red Bull concept offers a larger active aerodynamic opening, generating more drag reduction on straights. While Ferrari has logged no technical faults, Red Bull’s wing failed twice on Verstappen’s car, at Spielberg and Silverstone, sparking safety concerns.

The FIA’s request focuses on whether both teams comply with the 400‑ms ngoba transition rule and whether the airflow reattaches reliably. If Red Bull cannot demonstrate full compliance, the body may consider banning the concept for the season or 2027—though that is not the current aim.

For Red Bull, a failure risks missing Spa‑Francorchamps and could dent their championship push. Other teams, like McLaren, are watching closely as they plan their own wing trials, but the FIA’s scrutiny currently limits the inquiry to Ferrari and Red Bull.
