New Red Bull boss Laurent Mekies said it felt "a bit unreal" to replace Christian Horner and has emphasised the challenge facing him and the team.

Speaking at a planned filming day with the 2025 car at Silverstone on his first day on the job, Mekies paid tribute to his predecessor and admitted it felt odd to be at Red Bull without Horner there.

Red Bull has pledged not give up on the Formula 1 title fight until it's mathematically impossible for Max Verstappen to win, even after Christian Horner was fired as team principal.
