After 1 race where he did nothing special and just had a lot of dumb luck?
Can we say the same about Bottas dominating Hamilton then?

Hamilton had the faster pace so no comparison.
Awesome data! Thanks for sharingAngelicPrincess wrote:So I wrote a script that records the speed of the car from the onboard qualy laps, sampling at a constant rate. The math is then straight forward to calculate the distance covered and plot the results as shown below. The laps taken into account are; Bottas', Leclerc's and Verstappen's.
What I find interesting is that the Ferrari seems to be doing very well at high speed corners. Although that might be because of Leclerc and not the car, from the data and the video he seems to be chucking the car in the corners carrying more speed and letting it scrub off before the apex.
The table below shows a breakdown of the time deltas. (S1 for straight 1, T1 for turn 1 etc.)
Ferrari seems to be dead-equal with Merc and RB/Honda from 150-250 kph. Then Ferrari has substantial fall-off (compared to Merc & RB) from 260 kph and higher.AngelicPrincess wrote: ↑07 Jul 2020, 19:01So I wrote a script that records the speed of the car from the onboard qualy laps, sampling at a constant rate.

The video available to me was 25 FPS. Analysing it frame by frame i found that the speed graphic was refreshing every other frame. So that is what I sampled. It equates to 12.5 Hz, 0.08 seconds per sample.
What are you expecting to find in a comparison between Lec and Nor? Anything in particular you are interested in?SmallSoldier wrote: ↑08 Jul 2020, 00:16

Any chance you could do something similar with Norris’s lap?

Examining each straight by itself you can see that the Merc and Red Bull start to pull away at around 180 km/h. By my rough calculations that is where the cars would transition from traction limitation to power limitation.bill shoe wrote: ↑08 Jul 2020, 00:55

This looks like either less time from MGU-K output, and/or significantly higher drag.
That's surprising because those symptoms don't seem to fit with the meme of Ferrari having a fuel-flow trick that was curtailed by the recent FIA settlement.
I was just wondering if we could add Norris to the comparison with Bottas, Leclerc and Verstappen, I am intrigued in regards to where Mclaren is lacking towards the others and where they might be making gains.AngelicPrincess wrote:What are you expecting to find in a comparison between Lec and Nor?

There are no silver bullets in power unit development, it will require steady gains that do not compromise reliability.
Fired and replaced with whom?fritticaldi wrote: ↑08 Jul 2020, 16:51The Ferrari is flawed in the following areas: Engine, Chassis and Aero. Basically the entire technical staff should get fired.
That will not achieve anything. There are plenty of talented engineers in these departments, it would be most unwise to let go of them. Firing people is the Ferrari way, but it is not productive. You need stability to achieve good results.I would like to know, with the same approach, how much power disadvantage does the Honda PU have compared to the Mercedes one?AngelicPrincess wrote: ↑08 Jul 2020, 12:49Examining each straight by itself you can see that the Merc and Red Bull start to pull away at around 180 km/h.

In order to further my investigation I created a straight line model and varied the parameters in an attempt to fit the data. The curves fit well if you were to set the parameter for power to be 6% lower across the rev range for the Ferrari compared to the Merc while drag being 3% higher.
If we were to assume that the Ferrari produces the same amount of power as the Merc, then the SF1000 would need to produce 15% more drag than the Merc which I think is highly unlikely. Plus the curve doesn't fit as well.
EDIT: Furthermore, if we were to assume that the PUs produce around 1000 BHP then the Ferrari PU is lacking around 60 HP which doesn't seem unreasonable.
I would be very wary of using my methods to give more numbers as there is inherent uncertainty in my "measurement" and it is a very simple straight line model. However I did try to fit the model to the RB curve and because the RB and Merc curves are so close it is very hard to tell. My model says anywhere from 2% down on power with the same drag to 3% more drag with the same power or any combination in between.
