D'Ambrosio confirms Hamilton's suspicions: the Ferrari simulator doesn't read reality as it should. The inaccuracies in the mathematical models betray the SF-26, sending it outside its operational window.
The team have already identified the problem that occurred on Charles Leclerc's car during the Monaco Grand Prix. But it's unlikely that it will be made public. Starting from Barcelona, Leclerc will go in Lewis's direction by also using Carbon Industries discs. We hope this will help him, but it's not guaranteed. Another piece of information, no update was made in Canada on the brakes, so nothing has changed on that part of the SF-26.
It seems that Loïc Serra (technical director) has also been requesting the brake disc change for a long time. Coming from Mercedes, he is very familiar with Carbone Industrie's brakes discs, and the fact that this request from Loïc, combined with Lewis’ pushed Fred to agree to it.
Charles is fed up with Brembo and it seems he will no longer use Brembo discs; he wants to try these new CI brakes discs in Barcelona.
To add to that, regarding when they introduce the engine upgrades, the circuits of Austria, Spa, Monza, and Zandvoort are mentioned.
No. Why would someone chose one peak number?dans79 wrote: ↑09 Jun 2026, 14:51so you think they just look at the max power output?PlatinumZealot wrote: ↑09 Jun 2026, 05:03ok you just said a whole bunch of nothing. That doesn't tell anyone how they are determining who is first second 3rd
In other words they measure the brake horsepower and an estimate of the indicated horsepower (ie before losses). That's all you can do with the ICE.
That just not possible. We're talking ~50hp assuming 575-600 for the RBPT. I don't think it is realistic that Ferrari would be that far behind. Based on the (limited) wheel to wheel action we've seen between a RBPT engined car and a Ferrari engined car the RBPT car does seem faster down the straights but its not that level of gap. Either the FIA has messed up the test in a way thats overrating the RBPT engine or RBPT are running it below its potential for reliability reasons.
What you see on track isn't just ICE alone, otherwise if the tests are to believed you'd see RBPT outperforming the Mercedes on the straights as well.gearboxtrouble wrote: ↑10 Jun 2026, 01:29That just not possible.

Indeed. Before the ADUO was released people were saying RBPT ahead of Ferrari but not by much. That we are supposed to believe in a 40-50 HP deficit is not credible. Another reason to be skeptical of the FIA and their methodology.gearboxtrouble wrote: ↑10 Jun 2026, 01:29That just not possible. We're talking ~50hp assuming 575-600 for the RBPT.

We don’t know what which team wanted, they never agree on anything so it’s too convenient to say it’s what “they” wanted. It’s also hard to say they knew what they were agreeing to when the method is confidential. I guess they put their trust in the FIA to come up with something representative.Farnborough wrote: ↑10 Jun 2026, 13:00Tombazis has bern quoted recently in regard to the method and measurement.Badger wrote: ↑10 Jun 2026, 11:57Indeed.

Effectively, that the teams wanted THIS current method of assessment and categorisation for PU evaluation. The FIA proposed more, I'll say "sophisticated" (as that's the broad view of it) which was refused.
We can't see either stance tight now, but likely that any method/route was going to bring this type of reaction as all judgment would appear to favour someone, that's depending which team you're standing inside.
‘Mekies did not want to talk about the verdict on Sunday night in Monaco. And although he suggested that the FIA's ADUO note to teams was 'provisional;, being a signed document means it is set in stone and will not be changed.’
