It could be very interesting regarding which team could use what engine with the new engine formula 2026 onwards.
Let's have a look at the options:
On the table are Mercedes, Ferrari, Renault. Honda, Red Bull, Porsche and Audi
I think Red Bull will stay with Honda
And I could imagine Renault will withdraw from Formula 1
So big questions would be: where will Audi and Porsche land? I think they will both enter Formula 1.
Perhaps Audi with Sauber as Andretti and Audi could also tie up at LMDh and Audi developped the LMP1 car at Sauber some years ago.
Porsche could go to McLaren (Andreas Seidl) or Williams (Jost Capito).
