2026 Scuderia Ferrari HP F1 Team

[AR3-GP]

Is the power measurement taken with the cap (FTM,\whatever) in place?

It is with the cap. The power measurement is taken from the torque meter that is installed on the drive shaft during qualifying and the races. When the exhaust is being strangled, the ICE can't breathe as freely, so there's less power coming out of the crankshaft.

So:

The measurement method is the same for everyone

and

Every team is all but certain to get a different power output from the same engine depending on choices made

How do they then decide ADUO?

My criticism is not that the measurement isn't the same for everyone. It's that the system is not well thought out. They are going to get slightly different power outputs but the FIA will average everything for each manufacturer. The variance isn't large enough that Mercedes would not be considered the most powerful engine.

The previous generation of engine has about 40% more air flow than this generation.. So I doubt that same 4 inch pipe with a flick will strangle it.

What if the variance is large enough that some engines meet (or don't meet) the deficit required for ADUO?

I've read that the flick tail system cost the engine 7-9hp because it strangles the exhaust. This is not in the spirit of the ADUO system. It is not supposed to compensate for aerodynamic choices.

That's an interesting idea, so you put a blockage in your exhaust that reduces your HP (or just make air intakes less efficient), get ADUO tokens to upgrade the engine then remove the aero blockage and you have overpowered engine?

Maybe it can't be done if they run the engines on a test rig.

Putting a cap on the end of your exhaust pipe reduces engine power output.

Reducing cooling in order to reduce drag, reduces engine output.
Why should I explain these??

Are you aware of a team that has reduced their cooling at the expense of power output, in today's formula which is dominated by PU?

Yes I am. EVERY team did that. I am stunned that this needs explanation, especially that I already wrote about this.
You would need many times the size of the cooling radiators than what every team runs, in order to cool the engine to its optimum efficiency. So every team loosing lots of engine power.
As I already mentioned, this is a calculation of cost benefit when you design the car.

Please, do not argue here with people over matters you do not understand, and when you do not read the replies intended to you.

[Farnborough]

As an example, from my recollection/understanding, AN "bumped" the Ferrari PU contracted to RB into the TR team on his arrival at RB, that in favour of the Renault PU and it's more favourable heat rejection statistic/characteristics, that to give advantage in cooling vs aero performance.

There's always a balance to be taken in development of the whole performance, trading certain aspect for another in performance within tight envelope is just part, a very intrinsic part, of F1 as routine.
