Because the Ferrari drops off after hitting top speed and Merc staying at it until braking?henry wrote: ↑01 Apr 2019, 21:00Last year I looked at the speed data from Hockenheim that AMUS published and drew the conclusion that Ferrari keep the MGU-K going longer and then at the end of the straight they use both the MGU-H and the MGU-K simultaneously to charge the ES.
The trace for the first straight at Bahrain seems to show a similar effect.
If they are doing this it means they can afford to charge the ES at a very high rate, perhaps 190kW. Two batteries anyone?
Yes that’s it.MtthsMlw wrote: ↑01 Apr 2019, 21:10Because the Ferrari drops off after hitting top speed and Merc staying at it until braking?henry wrote: ↑01 Apr 2019, 21:00Last year I looked at the speed data from Hockenheim that AMUS published and drew the conclusion that Ferrari keep the MGU-K going longer and then at the end of the straight they use both the MGU-H and the MGU-K simultaneously to charge the ES.

This isn't the joke article.
I think this trace is faulty or changed to misrepresent reality.MtthsMlw wrote: ↑01 Apr 2019, 16:44Though this graph from Q3 shows it's just like last year with Ferrari having an advantage starting at around 225km/h.
It's even bigger this year. This wasn't the case in Melbourne so it seems that Ferrari only now turned the engine up to its limit.
Toto Wolff: "With lower drag, you're only gaining a tenth at most. That's sheer engine power."
From AMuS:
The engineers had jumped into their analyses right after the training. First statement: "Ferrari gains on us on the straights with and without DRS. So it has nothing to do with drag." Second finding: "During the test drives in Barcelona we were on a par in terms of power. In Melbourne we were slightly ahead. In Bahrain they were clearly superior to us. The outlier was Melbourne. Something must have gone dramatically wrong with Ferrari."
[...]
"They beat us at the beginning of the straight with more power and in the second half because they don't switch off the MGU-K as early as we do. Our speed curve flattens out in the end. Ferrari's continues to rise."

Here is a graph from Melbourne. Quite different, no power boost.

The audio ("phonometric" in Google Translate) analysis gives info on frequencies of various components. It probably gives insight into whether the H is running and how hard, this being determined by differences between car accel and engine rpm relative to turbo whine (blade-pass frequency). It may be able to determine if the K is under load due to increased noise/whine from the geartrain between K and crankshaft. This noise analysis can't determine power curves which already come from the GPS data that the FIA shares with all teams. The noise analysis can give more detailed perspective on what a competitor's powertrain is doing over the course of a lap where the teams already know the competitor's net delivered power from the GPS. Noise analysis helps reveal a competitor's means to achieving their end.

The reason Leclerc's DRS opens earlier is because he is ahead on lap time. The other traces have been overlaid to give a comparison at any point in time, but the DRS is shown at the point in the lap time that the flap was opened. Leclerc was ahead so his DRS naturally opens earlier in time.
Both graphs were found on funoanalisitecnica ? Can't find the articles, could you help please ?MtthsMlw wrote: ↑01 Apr 2019, 16:44
