They have no input to the PU packaging or compromise between thermal requirements and aerodynamics.
Yes this is true, I agreed with that earlier. I just can't see any other advantage and I don't see that as being much of a disadvantage.
All of the engines would likely fit into all the cars with some chassis adaptations and minimal impact on aero other than by cooling requirements. Even then I don't think they'd differ much now.
New regs would see greater engine disparities for a couple of years before equalising though.
The cooling requirements are not mandated by the aero / chassis team… The engine manufacturer/ department will make the most powerful and reliable unit they can make and then let the other departments know what they requirements are and not viceversa… The teams build their chassis (Tub) and their radiators to meet those requirements and their new car design… That’s why you can have the same PU in a car with Zero Pods (Mercedes), a car with a very narrow mid section (the MCL36), the 2 different iterations of the AMR last year and a very different side pod arrangement like the 2022 Williams… All of them with same PU architecture
When the Mclaren moved from Renault to Merc there was a wealth of information around the change. Engines required different level of cooling in different places, some engines more heat efficient than others etc
That said, I don't think that it is THAT much of a difference that it can impact the cars that much, but who knows, perhaps even small changes to the angine cover or Sidepod shape can make large changes to aero efficiency.
But ultimately, teams get the CAD designs early on and the thermal profiles, so they are able to design an effective solution that fits the car with probably almost no impact so again, I can't see much of a disadvantage.
I just can't see an engineering reason that stands up as to why works team is so good and has anything more than minor benefits.
Even the idea that the engine is designed for a chassis. I highly doubt it, if the engine team says they can get 30 more HP from this other shape, they will take that shape and the chassis will change for it, because ultimately the engine can be made to fit without compromising aero or by working around it.
