The hump in the final area of the engine cover (where is the 27), appeared in the Haas while showing the new livery for the 2023 car, is the same as that of last year Alfa Romeo and was due to the push-rod rear suspension.
II think that was more than a presentation of the livery, as the car is completely different from last year.
Maybe there was something of the new Haas.
Ferrari and Haas share the engine, the gearbox, and the suspensions.
Are we going to see a push-rod rear suspension on the 675?
