Much of that was the Ferrari PU.
The whole Haas team concept no longer makes sense to me. Sauber is moving to Audi works team, Racing point has become Aston Martin Racing, William's is partnering with Porsche and SAT are still a B team, but have their own factories in Italy. Honda put their name in the hat for 2026 new PU regs, I would not be surprised if they buy SAT. Haas has no project to go their own way and have rejected advances from Andretti on partnership. I can't see how they don't remain perennial bottom feeders. If they succeed, they'll just be a Symbian being.
