What happened: The FIA has requested additional information from Red Bull and Ferrari regarding their rotating rear wings, known as the 'Macarena wing.' The regulatory inquiry follows Red Bull's internal investigation into a recent crash at Silverstone involving Max Verstappen.

Why it matters: The 2026 technical regulations permit active aerodynamics, allowing rear wing flaps to rotate and reduce drag on straights. Safety concerns center on the reliability of the airflow reattaching consistently when the wings revert to their high-downforce configuration for cornering.

What to watch: Red Bull team principal Laurent Mekies stated the constructor will leave 'no stone unturned' in its internal review as both teams cooperate with the governing body.
