2026 Hybrid Powerunits

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Peak power and the power band are not the same thing. It is like the difference between the Renault V8 and Mercedes V8 in 2010-2014.

The ICE measurements will also fail to take into account exhaust flow restrictions induced by the flick tail mode. Ferrari sacrificed some horsepower when they put a cap over half of the exhaust pipe, and they also sacrified some power when they used the minimum cross section tail pipe in order to speed up the exhaust air flow for the flick tail mode.

I don't understand how it would have been possible for the FIA to take into account these basic concepts, and without taking this into account the results of the ADUO can be distorted.
I’m sure the FIA is looking at a lot more than peak power…

My point is this is just one of numerous challenges, not that it is THE challenge. That's the issue with no transparency. We don't know.

Furthermore the point is they are looking at combustion engine to dictate hybrid system development tokens. The leading team on the ICE measurements will be subject to a hybrid system freeze until 2028. There are numerous mechanisms by way this system is not the catchup mechanism that it is supposed to be. It is possible instead for it to grant the real lead PU (Mercedes) and even greater opportunity to get ahead.

Hybrid systems are a big development area and in a 50/50 formula it makes no sense that hybrid system would not be a performance index for "catch up".

There is an argument to be made here that the manufacturers did agree to this, so right or wrong, it is what it is from that standpoint.

They also agreed to the 50/50 regulations. This is just my opinion. I have no decision-making power.

Interesting article from the race that suggests that Ferrari is now looking at doing a u turn on its opposition to the 60/40 proposal for 2027. They had assumed that Mercedes would be the benchmark and opposed the 27 change do that it could maximize its perceived ADUO advantage over them but with Mercedes now also qualifying for ADUO, they might conclude that their best move is to push for an all new engine for 27.

It's so tiring watching self-interest destroy F1.

Mercedes must be pissing themselves.

Not only made the best PU, but played the system to gain an upgrade. Fair play to them.

The problem is the FIA keeping the measurement method secret. No transparancy. Nothing stays secret within this environment, so teams will get inside knowledge on how to play the system. So teams more, others less. If you want a fair system, you need transparancy.

Ferrari switching up maybe the best thing moving forward... but the fact that Mercedes actually "WANTED" the 60/40 split and the cars will have less downforce next year... man you just gotta wait until 2030 because Mercedes may have literally thought of everything in these regs.
