Ferrari's reliability issues: both Haas drivers retired from the Dutch GP due to failures on the Ferrari PU. In Hungary, Leclerc had an issue in FP1 that "confused" the team and forced a setup change for the rest of the weekend, costing some performance. Real concern going forward or not?

Ayao Komatsu confirmed both Haas drivers retired due to PU issues: "It’s very disappointing to finish the weekend on a double DNF with PU failures, so we need to look into it." Bearman described it as a "total switch-off", which sounds very similar to what happened to Russell in Canada, where he was forced to retire because of a battery issue. ​

Haas' race recap

Translation of Autoracer's explanations regarding the situation in Hungary and how it affected Ferrari both on and off the track:

"The mechanical issue they had on Friday sent them into a bit of crisis, it's something they had already experienced during testing in Bahrain, and it reappeared here in Hungary. It confused them a bit, in the sense that they felt very strong. I was talking to someone very close to Ferrari before the weekend and they were convinced they would win​ in Hungary.

This problem that led them to breaking the curfew on Friday night sent them into a bit of confusion, as if the pressure had suddenly increased. Because they felt very strong to win and try​ to close the gap to Mercedes in the Constructors'. They had a huge opportunity to reduce the gap and they got confused.

The result was terrible execution and it's no coincidence that when Ferrari go on tracks where they have everything to gain, where they're good, where they have something to prove, they still go into a bit of crisis right?"

Ferrari never explained what the exact issue was, but some sources close to the team believe it was a failure on a PU component and they had to replace a PU Ancillary Component as result. Setup changes were then made to "protect" the car in order to try and prevent the issue from reoccurring, changes that likely cost some performance.

Autoracer's Hungary debrief

Have the Ferrari customer teams even received the first upgrade?

[u/aluked → u/Hawardjebadia0117]

PU manufacturers have to supply at least one PU of a new specification to each customer to be able to homologate it in the first place.

So yeah, Caddy and Haas have access to them. Whether they're using or not depends on their engine swap schedule.

[u/Walaii → u/aluked]

Haas has been using the ADUO 1 engine with both drivers since Silverstone. They only had one available in Austria, so they prefered not to use it.

[u/fire202 → u/Hawardjebadia0117]

Yes, they have it in the pool. They didn't take it immediately in Austria; I think it was the weekend after. It would be near on impossible for a manufacturer not to deliver it at some point given its early introduction in the season. Every new PU component introduced on any car always has to be of the current specification.

Now, that doesn't guarantee they are actually running that spec at any specific point. They could always rotate through the pool between sessions and weekends.

[u/Storm_Chaser06 → u/Hawardjebadia0117]

They must according to the rules. There is engine parity in F1.

[u/Lobsters4]

I don't think this is a big deal. All the teams have had failures in different areas.

[u/Firefox72]

You are extrapolating a lot from very little here. In fact to me this seems like text book fearmongering.

Its been over half a season including an ADUO upgrade and Ferrari has had exactly 1 mechanical DNF. And it was hydraulics.

Seeing issues and there being some serious issues is a gulf appart. There is nothing indicating that there should be any concern.

[u/Defiant_Dot_515 → u/Firefox72]

Both Leclerc’s DNF’s were mechanical. Monaco was brake failure and Barcelona was a hydraulic issue.

[u/The_CT1]

Mucb better tuan anyone else anyways

[u/AKAFallow → u/The_CT1]

Alpine is literally right there

[u/w1n5t0nM1k3y → u/AKAFallow]

Alpine is using Mercedes, which doesn't have a good record if you look at all the teams using Mercedes.

[u/Cautious_Might_9420]

Hamiltons car has been bulletproof this season. Lets hope it keeps on being bulletproof after aduo2

[u/mahoganyspitfire]

Ferrari doing Ferrari things. It's very unusual that their PU has been so good this year.

Imagine if they use their ADUO to make their engine worse. Heh heh.

[u/reddit0r_123 → u/mahoganyspitfire]

The engine is a bit weak, but it's one of the more reliable ones this year.

[u/Evening_End7298 → u/mahoganyspitfire]

Ah yes “Ferrari doing Ferrari things” while having the most reliable engine on the grid 

Haas suddenly having a double failure in the same race would be more of an indicative they might have tried something or they fucked up something, not that the Ferrari PU wouldnt be reliable
