2026 Hybrid Powerunits

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.

Get OEMS out of F1. With the cost cap F1 really doesn't need them.

Get rid of teams as well then, because they do the same.

As long as teams have this much say in the rules and regulations, this will continue to be a problem. The inmates are running the asylum.

FIA stupidity... They have all the power to make the regulations (apart from the Ferrari veto), yet they allow teams to manipulate them all sorts ways.

Because the inmates are the asylum, to link to the post above.

Where is the value, the teams or the brand? Ultimately it's the teams, as they previously threatened to leave. A 'GP1' with Ferrari and Mclaren would win out over an F1 that found itself with a logo and I guess, scrambling around for F2 teams to plug the gap...

The FIA can make regulations, sure, because the teams / Liberty let them do it. If the FIA go too far, we start hearing noise about the teams / Liberty bailing again.

I think any hypothetical split scenario would have the teams breaking away from FOM and/or the FIA with the teams setting up a direct ownership model of an entity like FOM, more akin to how the English Premiere League formed.

You just need 2 manufactures to not want 60/40% to block it.

They could do that if they wanted to race on Mars or the Moon, but they couldn't do that on planet Earth. If you think Liberty Media paid $4.4 billion for the Formula 1's commercial rights business only for it to be easily broken up, you've got another thing coming. Their lawyers have made sure it's iron clad BEFORE they bought anything.

FOM stands for Formula One Management, the company that manages the commercial side of Formula 1. FOM is ultimately controlled by Liberty Media, which acquired Formula 1's commercial rights business in 2017. They effectively have veto power over everything. The FIA does what it does, they have veto too, but if FOM isn't happy with something, it can put a stop to it. Since FOM is represented on all the steering committees, disagreements are rare. Plus, all the teams are extremely happy with F1 because the cost cap that was implemented is giving every team deep pockets.

In F1, teams are always going to disagree when it's to their advantage. You'll always have one team wanting 50/50, another wanting 45/55, and another wanting 40/60. Today it's this issue; previously it was energy recovery on the front and rear brakes, and before that it was something else. These are relatively minor differences, which is why it's so difficult to make changes between the normal regulation-change windows.

Don't mistake this for teams or manufacturers wanting to take their ball and go home. The manufactures and teams have gone through this for decades, they know the game. When the next regulation window opens, four or five years from now, it will be much easier to make changes. Right now, any PU regulation proposed change can be blocked if the FIA, FOM, or more than one manufacturer opposes it.

Yo haven't been around 2007 (ish)? The concorde agreements are signed for an exact number of years after that, the teams can do whatever they want. If most of them decide to organize a breakaway series they can do that. And FOM can make do with one two backmarker teams.
But it's not going to happen. F1 is a money printing machine nowadays for the teams.

It could happen and it very nearly happened less than 20 years ago. Everyone is happy with the status quo as it currently stands, but that doesn't mean everything will be sunshine and roses for all points in the future. Concorde agreements are periodically re-signed and renegotiated, and if something rapidly deteriorated with FOM and or FIA and the teams couldn't agree to a new Concorde agreement then all bets are off. I don't think it's likely that we see any breakdown anytime soon, but if it were to happen then my opinion is it is more likely it will be a breakdown between the teams and FOM rather than with the FIA.

The thing is you can't do it alone. You'd have to do it as a big group. Since any 2 manufacturers could block an in window reg change. Those 2 manufacture can be supporting anywhere from 2 teams to half the grid. Also F1 has all these agreements with all these promoters around the globe that are certainly gonna be asked to block the splinter group. The splinter group has gone from making tons of money to not being sure where the next paycheck is coming from. Plus, you have Cadillacthat just spent .5 billion dollars just get into F1. They're not about to turn around and throw that all away.

No cylinder, as referred to by C5.1.3, of the Engine may have a geometric compression ratio higher than 16.0, measured in the following conditions:
• Until 31 May 2026: when the Engine is at ambient temperature
• From 1 June 2026 to 31 December 2026: when the Engine is at ambient temperature as well as when the Engine is at 130degC. Any component, assembly, mechanism, or integrated arrangement of components that is designed or functions to increase the compression ratio in operating conditions beyond 16.0 is prohibited.

To:
No cylinder, as referred to by C5.1.3, of the Engine may have a geometric compression ratio higher than 16.0, when the Engine is at 130degC. Any component, assembly, mechanism, or integrated arrangement of components that is designed or functions to increase the compression ratio in operating conditions beyond 16.0 is prohibited.

There are one or two other changes, but not performance related.
