If true, how come SF1000 seems to be a radically different car to SF90? It now runs high downforce instead of low downforce. It does not seem like a mere SF90B to me, at least not in aerodynamic concept even if it physically reuses the same or similar structural and chassis components.

At the SF1000’s launch, Mattia Binotto revealed that Ferrari had created the SF1000 with the aim of “trying to look for maximum aero performance and maximise the downforce level”. And Leclerc confirmed that it was mission accomplished on that front, when asked where the car was best.
“I think the biggest strength is the speed around the corners. I think on that, we have achieved our goal. Then we need to wait and see for the overall performance of the car, but… we are going around the corners quicker than we did last year, so that's positive. But we need to keep working on this car to unlock a bit more performance.”

Could they have got the gearing wrong?!? I haven't seen rpm traces but I'm a bit skeptical that this is all down to aero.ncx wrote: ↑04 Jul 2020, 21:32LEC, last year pole lap vs today Q3 comparison from turn 1 to turn 4.
Acceleration is quite similar until speeds at which drag becomes very relevant. I don't think it's straightforward to determine how much of the deficit is due to higher drag or lower power. In the corners the SF1000 behaves better, suggesting a significantly higher downforce; that may have been achieved in an aero inefficient way.

Or at speeds at which fuel flow limits become relevant.....
Well said, the part about them adding downforce without sacrificing efficiency is right on the money, they didn't do a 180 on the concept like some people think they did (which makes some of their supposed cornering gains impressive)TheFluffy wrote: ↑04 Jul 2020, 18:29Guys I don't think we need to panic after today... poor performance was expected for these few races. Just commentators, media and some of us somewhat expected them to take the sandbags off. The matter of the fact is they based their design of SF1000 on the SF90 but focused on adding maximum downforce while sacrificing efficiency.
Isolating today's performance, it is a combination of the weather conditions and poor qualifying setup that caused them to struggle that much. I absolutely do not believe today is a true reflection on how bad they are (as proven from their superior race pace compared to midfield) Think about it, I believe Red Bull's time is more or less same with their last year's time so it reflects on the conditions making some cars to not truly show their improvements.
Of course, this is part of a bigger issue of their lack of correlation. And hopefully the upgrade will put them on the right track. I think they most likely will now try to pursue the same level of downforce while extremely making it a lot less draggy. Cuz being slowest on the straights is definite alarming but their cornering speeds aren't bad.
This can also mean less electrical energy to power MGUK....ncx wrote: ↑04 Jul 2020, 21:32LEC, last year pole lap vs today Q3 comparison from turn 1 to turn 4.

In the article of FormulaPassion, they analyze that graphic and say that the there is ALSO an engine problem (together with a drag problem). They suggest that they have less torque and so are forced to use all the hybrid part too early in comparison to last year, so they are missing it later.ncx wrote: ↑04 Jul 2020, 21:32LEC, last year pole lap vs today Q3 comparison from turn 1 to turn 4.

I tend to agree that it's mostly aero that slows them on the straights. The gap for example to Merc gets bigger the higher the speed. Drag is proportional to speed squared.ncx wrote: ↑04 Jul 2020, 21:32LEC, last year pole lap vs today Q3 comparison from turn 1 to turn 4.
