Lots of reports from track in BCN saying Ferrari slower due to new FIA fuel flow mesurment.

and merc are to be checked by fia before next race

Lots of reports from track in BCN saying Ferrari slower due to new FIA fuel flow mesurment.

Given that they lose about .5 second in last sector (low speed, needs good traction) I would tend to think fuel flow has very little to do with Ferraris performance here.

[henra]

Any technical reason to why Ferrari suddenly became so slow, compared to Mercedes, on low speed corners?

Good question!
One possibility would be that they have a traction Problem. Seb couldn't get past Bottas in the last race and now it happened to Kimi as well. In both cases they lost out heavily at the beginning of the straight. Naybe more a mechanical than aerodynamic issue?

Yep, I noticed that Williams was quicker out of the chickane than Ferrari. Wonder if the problem is on the suspension or on the engine side.

A mercedes engined car was checked and approved under the current rules.
They even showed FIA how illegal fuel flow will show will turn out on the different sensors just by increasing the fuel flow ..

Kimi said that compared to other cars the Williams were very difficult to follow. He could easily catch them, but couldn't close the gap. Apparently Williams leaves behind a wake of very dirty air compared to others.

the Hard tyre compound is Ferrari biggest problem, not the fuel flow (provocation of Mercedes).

[turbof1]

The fuel flow issue is a storm in a barrel, created by the teams themselves. It's born pure out of mistrust towards the opposition, and the fia already clamped things down during testing when they asked to put multiple sensors everywhere. No team would have run such a fuel collector system after that directive, since it would have been picked up by the added sensors. The new directive doesn't change things; it only aims at forbidding such a system in the future, and to ease the teams.

Ferrari always had less traction the Mercedes; that has been since winter testing apperent. Expect it to be very noticable in Monaco.

Didn't seem to be the biggest problem in other places like Sepang where Vettel was the fastest/cofastest on S1/3 but was almost 0,6s down on Rosberg's S2(Vettel only used Primes on Sepang's qualifying). Previously, Ferrari's biggest gap was on downforce sectors. In Barcelona, it turned out the opposite. They were no more than a couple of tenths down on S1/S2(where the mid-high speed corners are) but 0,45s down on S3

Before Barcelona, I was expecting Ferrari to be a real threat in Monaco but, now, I think Mercedes will easily walk again.

I too surprised with the same in Bahrain also they are very quick in S3 which is mostly Traction section. Perhaps with the updates they too much focused on Aero which might have made a comprised suspension

[turbof1]

In Bahrain during the race, when Vettelwas behind Bottas, we clearly saw Bottas pulling away out of the last corner. Note that traction is only one of the factors leading to a sector time; there are other forces at work too, like slow corner speed etc. I'm only pointing to one particular item.

This is indeed strange. Kimi in the old configuration in his fastest S3 was much faster than Vettel. Edit: And in Qual, he was on par with Vettel in the last sector, but losing heavily in S1 and esp. in S2.

How can you improve Aero and in the same time losing on slow traction bits of the circuit, I wonder?
Has the new aero changed pressure center, and required much different settings, eg. stiffer rear suspension, worsening traction?

It is good that testing resumes this week. Ferrari need time to learn about their new updates. According to Mr: Arrivabene 70% of the car is new. They need time for fine-tuning set-up.
