100% agree. LeClerc and Sainz have excellent chemistry and with LeClerc signed through 2029, giving Carlos a 3-year extension through 2027 would provide solid driver stability for the team, which I see as important to support Vasseur's overhaul of the technical team. LeClerc is the defacto #1 of the team right now, but is that going to be the case when Lewis arrives? And is Lewis comfortable - and willing - to play #2 to ride out his career?
If this is true, I can only see this as a sign that either Lewis has lost any faith in Mercedes having resolved their issues with the current chassis and a belief that their 2026 car will be flawed because of this, as well, or the wind tunnel and computer modeling for the W15 must really look ugly.
As for breaking his contract with Mercedes, we know the top drivers all have "escape" clauses, but with Lewis 3rd in the WDC and AMG 2nd in the WCC, either that clause was "win the WDC in 2023" or Ferrari is going to pay an insane amount of money not just for Lewis' salary, but to buy out his remaining AMG salary.
