McLaren chief executive Zak Brown insisted his team "won't miss a beat" despite changing their team principal far earlier than planned.
Andreas Seidl was contracted to remain in the role until the end of the 2025 season. Earlier this year he communicated his plan to leave after that – the presumption being he had been recruited by Audi as the German carmaker prepares to enter Formula 1 from 2026.
But the timeline changed when Mattia Binotto resigned as Ferrari boss and the Italian team turned to Frederic Vasseur. His departure from Sauber, currently racing under Alfa Romeo branding, saw Seidl's switch moved up and he has already been confirmed as the new chief executive of the group.
