A new Red Bull era begins under Mekies at this weekend’s Belgian Grand Prix. He was appointed after 18 months at Racing Bulls. He worked at Ferrari for five years, as deputy team principal and racing director, and at the F.I.A., which governs Formula 1, for four years, initially as safety director and then deputy race director.

Former Red Bull boss Christian Horner shared a video of himself horseback riding on the day of the Belgian Grand Prix, which marked the end of his leadership era. Laurent Mekies, the new boss, began with a win in the sprint but faced challenges in the main race with strategies affecting results.
