F1 2020 Pre-Season Testing Thread

[etusch]

There's quite a good article by Mercedes about how they analyse other teams' laptimes: https://www.mercedesamgf1.com/en/news/2 ... s-learned/

Alongside the gradual capture of the testing fuel levels, the strategists are watching the speed and acceleration traces that come from the GPS system to look for changes in PU power. As the teams cycle through the power modes, we can get estimates of what power levels are available to each type of PU, and when they have been employed. This allows us to refine the pace estimates for each team, correcting for the mode usage in each run.

Very good thanks

From the same article Why have Ferrari spent this test running their PU consistently at much lower levels than their partner teams?

Why indeed?

What the article doesn’t mention is a key tool they have at their disposal. They can run their estimation tools against the known data of their own runs. Tyre performance, weather, track evolution, etc.

Bottas and Vettel were as fast as in their Q3 laps from last year. Hamilton a tenth down and Verstappen two tenths down. We don't know to which extent Mercedes and RBR were pushing, but we can be sure that Ferrari wasn't pushing so it's a good sign they managed to match the sector time of last year's qualifying.
Once they start performance runs next week, the important question to be adressed will be, how well the tyre temperatures will stay in the window in the last sector. This was the main issue last year.

yes i noticed that too! Have they overdone it on the packaging?

Or just safe mileage. Chassis data collection on the works team, engine data collection from customer teams.

Bottas was not as fast as his qualifying time from last season.

Edit-1 were you talking about their S3 times?

That's gone under the radar with Vettel then, they are playing their cards very close to their chests IMO.

RBR never used anything softer than C2, Bottas was on C5. Do you think there's .7 seconds between the C2 and C5 tire in S3? I think there's a 1.3 second difference between the C2 and C5, so extrapolating that to S3 it's probably worth around .5? It's really close, too close to call, but at least we know they're thereabouts.

I just mentioned the times to complete the top cars. I know RBR is gonna be much faster. The car looks to be very competitive.

Or just safe mileage. Chassis data collection on the works team, engine data collection from customer teams.

Safe Mileage that cost them a PU failure though.

Or excuse to run a different spec power unit? Why announce to the competition that you're testing different power units? Have we seen the 2020 Ferrari power unit yet? Do we know if they're still using the same layout? Remember the teething issues Honda had when they made the switch to split turbo? Took them a while? How fast do you suppose Ferrari could make the switch?

Have Ferrari split the turbo, source please?

No, the layout is unchanged.

yes, it just raises the question why more normal modes might not be safe. And then when they seemed to turn it up on the last day it went pop. Well now they have two days less to fix it than if they'd tested it to that level at the start, which is the point of testing, so i'm not sure either way
