woow.... now that gives a completely new angle...so much for fuel saving...almost every line after pit stop was about watching fuel.
Based upon the radio it looks like Ferrari Underfuelled both cars in order to have pace on sunday. And since Vettel was trying to hold on to the front runners on first stinct must have burnt more fuel and Ferrari early stop was to gain position from hamilton and after the initial attack from hamilton eases due to circuit characteristics.. they might have planned to coast to the end.. but it didnt work out on the track position so limped home that way i guess..

On the other hand Leclerc after the initial mistake didnt have much pace and dropped more than a pitstop from the leader and chance had more fuel in the end, could push more and caught seb who was coasting to reach the end.

No safety car this race.. that too would have compromised fuel
Hopefullly thats all it is...coupled with setup issues...

Just some understanding based on the radio msgs

There is a lot of wild speculation appearing on this technical thread about the SF90 . Can you please calm down and post sensibly. If you want to discuss team matters, use the team thread. If you want to discuss the race, use the race thread.
Thanks

What does FS mean that they keep asking to change?


p.s. Somebody is very giddy today deleting posts. Maybe take a screen break and have a coffee or something.

Running the engine richer to keep the temp down? In an article from motorsport.com it was mentioned that the engine cover wasn't opened enough to cope with the heat.

Maybe fuel strategy?

[Sharnlarry]

The steering wheel shows the fuel saving modes or‘fs’ in the bottom middle. Looks like they have
FS2 FS4 FS6 FS8 as different fuel saving modes.

The vibrating T-wing. A help, or a hindrance?

Motorsport.it are claiming that lack of pace in Australia was a combination of suspension and a tight packaging causing overheating of the PU. Apparently Ferrari knew during free practice that their performance would suffer.

"Ferrari analysis: two deadly contributory causes that have sent the Red into crisis

Maranello's men had already understood in free practice that Ferrari would have to play a weekend in defense. The mistakes were made at home and there was no way to repair them on the track. The lesson was served and in Bahrain the SF90 will return to be that of Barcelona...

The Ferrari debacle in Melbourne should be analyzed with coldness and without hysteria. The SF90 seen in Australia was too bad to be true. Now it's up to Mattia Binotto to prevent the team from panicking, to find the bandole of the skein completely lost among the... kangaroos.

The disaster has emerged from a series of factors that we try to analyze.

Sebastian Vettel got his fastest lap in the race at the 16th lap in 1'27"954, two laps after mounting the Medium (yellow) tires with which he arrived at the checkered flag. Since then the German has not been able to improve his performance, which in the end was the eighth of the Australian GP 2019.

The SF90 got the best result when it still had a full fuel tank, but then it didn't know how to get its times down even though the Red was getting lighter because of the fuel consumption, a sign that on the SF90 there were some serious problems to keep an eye on.

The German, in fact, got a gap on the lap of 2"384 from the limit reached by Valtteri Bottas who, with the Mercedes, gained the 26th world championship point of the weekend. An enormity for modern F1, especially if we compare the performances of two tops.

Charles Leclerc, who respected the Scuderia's order to join the captain in trouble without trying any overtaking, got his best performance on the last lap, the 58th, running in 1'26"926 at 1"346 from the Finn, placing fourth in this classification.

Between the two Reds, a second was danced: when such clamorous differences emerge, it is obvious that it is not possible to reduce everything to just set up problems. It is clear that Seb's Ferrari from a certain moment of the race had to reduce its pace, but to avoid what?

Without wanting to take into account the top speed at the speed trap of Pierre Gasly with Red Bull that has long been in the wake of Daniil Kvyat's Toro Rosso (the Frenchman at Albert Park has touched the 321.9 km/h!) it may be interesting to compare the speed of Valtteri Bottas (who has made solitary race) with that of Vettel.

The silver arrow reached 311.4 km/h, while the German's Rossa did not exceed 303.7 km/h and Charles Leclerc, probably more loaded aerodynamically, stopped at 297.4 km/h. In short, the 7.7 km/h taken by Vettel at the speed trap must make you think.

Mattia Binotto, talking to journalists after GP, said that "...we have not found the grip we expected and when you are in these conditions in the curve you struggle, and you do not go out as you should on the straight".

The set-up problems were obvious: the SF90, which had amazed Vettel on the first day of testing in Barcelona, was transformed in Melbourne into a difficult and unpredictable car on the gibbous asphalt of the semi-city circuit.

What does that mean? That the single-seater that was driven with two fingers in Spain had an unpredictable behavior from one curve to another, not giving the drivers the confidence to drive to the limit.
The SF90 looks like a car that we could call pitch-sensivity: perfect on a surface that is a pool table, while it suffers on jerks if the suspensions do not absorb the roughness of the asphalt. And then there would have been momentary losses of load and grip that the simulator does not measure and attempts to remedy them with set-up changes have served no purpose, or almost ... The front suspension of the Ferrari is more conservative than the Mercedes that has more possibilities for adjustment and trim. In Bahrain the Red will find a more uniform background so this problem should disappear completely, finding on the track the values of downforce seen in the wind tunnel.And after all in Maranello have focused more on the aerodynamic exasperation with the mouths of the radiators very small and very streamlined bellies to have little resistance to advancement and, therefore, good top speeds.Judging by the images we collected from Melbourne, Ferrari presented itself in Australia with the most closed aerodynamic configuration of all, relying on the extreme cooling system that was specially designed to offer aerodynamic advantages.If Mercedes maintained limited outbursts at the tail end, like the Rossa, at the sides of the cockpit the W10 was more open than the Ferrari: in addition to the increased grip in the shape of an Esse behind the anchorage of the Halo to the body, we saw the three gills at the sides of the cockpit that had a bigger vent than usual at the tail end, picture below. Perhaps the Scuderia technicians have deliberated for the first GP a too closed car that may have triggered temperature problems at certain components of the power unit. The sum of the two problems may have caused the disappointing performance of Ferrari in Melbourne, but in Bahrain the music should be completely different because the SF90 will be adequately prepared for the heat of the emirates with a configuration designed for desert temperatures. In short, it turns the page and looks to the future..."

Temperatures are much higher in Australia this time of the year then they are here in Europe. So that is why they have enlarged hot air outlet at the back, like all of the teams did as well.

Even with that increased outlet for cooling it wasn’t enough. The claimed cooling gains by Binotto may not be as good as he thinks

[aral]

Temperatures of the car or of the weather have not even been suggested as being a cause of any problem.

[SiLo]

Look at all the other cars though, they have larger openings in the airbox and sort of in the sidepods too.
