Thanks for the information. Finally it's official you say.  There've already been strong rumours regarding him to join Cadillac in 2026. It'll be nice to see him back but I doubt if he'll be competitive again...

In this kind of situations, teams generally prefer a young driver beside an old and experienced one. This is why we might see Mick in the 2nd seat. But we'll see. Cadillac is new around here. I wonder how competitive they'll be.

And this will be entertaining also, if the whole RB drama was about the votes in the RB team and the owners coughing money at RB gmbh, wait till you see the structure of the F1 team and TWG.
Anyhow, it will be funny for a team that has experience in what is essentially the opposite of F1 when it comes to rules, to join the circus!
