Wow, that is a surprise as I thought he was on a 2 year deal with Mercedes. I assume there is a break clause after one year. I think this is his swan song contract is probably right. 2025 to get to know the team and 2026 for new regulations.
The last time we had moves announced so early was 2020 with Sainz to Ferrari & Danny Ric to McLaren.
I do wonder if Alex Albon might get the Merc seat.
Carlos to Audi is a real possibility given his Dad’s links. Carlos appears sensible and will see it as a pragmatic move.
