📊BEST SECTORS
(Everyone on Softs, except for BOT/ZHO/SAR on Mediums)

🟡RBR was quickest in every sector!
Next quickest car:
S1: 🔴Ferrari (+0.03s)
S2: 🔴Ferrari (+0.02s)
S3: 🟢Merc (+0.08s)

🟠McL was quick in S1, but their low top speed held them back in the fast S3

Verstappen's best FP1 lap was just 0.015s away from the ideal lap (VER S1 and S3, PER S2)⏱

NOR and STR didn't combine their best sectors into their best laps:
🟠NOR would have finished P8 (instead of P10)
🟢STR P11 (instead of P15)

Weak points:
⚫️Merc S1
🟠McL S2
🔴Ferrari S3

🗒Notes on Japanese GP Quali!

🔵VER gained 0.68s over his last pole: LEC/ALO/HAM wondered how they could be so far after good laps!
🟢Aston: in Q1, ALO was P2, STR P16. Better lineup needed
🔴Ferrari has lost their quali pace since FP3
🟠Solid P3 for McL, but was P2-3 last year

Who surprised you the most? And WHY?🤔

AERO PROPERTIES
➡️Higher mean Speed (more performance)
⬆️Higher top speed (lower drag)

🟠McL got P3 with the lowest top speed on the grid! Crazy downforce, but they need less drag for a front row. Same for🟢Mercedes

🔴Ferrari lost their top-speed edge🤔

⚪️Haas=Rocket🚀

BEST SECTORS - Japanese GP Quali
🟡RBR was quickest in all sectors, but as in FP1 PER beat VER in S2

🟠McL's excellent downforce helped them massively in S1: virtually as quick as RBR!

🔴Ferrari was TERRIBLE in S3: slower than HUL, ALB, both RBs...

What's your opinion?🤔

THROTTLE USE - Quali

🟡RedBull got pole by being able to stay full-throttle for 2/3 of the lap: they put the power down better than anyone else

Similar for🟢Merc/🟠McL, but their high drag caused a loss of pace on every straight

🔴Ferrari: no grip, and 'meh' top speed!

INISECTORS - Quali

🟡VER and 🟠NOR were impressively quick in the fast S1 snake, leaving nothing on the table for🔴SAI! Their downforce was unmatched

In addition to that, RBR had lower drag➡️Fastest at the end of most straights

🔴Ferrari was quickest only out of T12/18

RACE PACE - #JapaneseGP

✅Improved the most over 2023 (s/lap):
🥇🟢Aston -1.87 (was terrible last year)
🥈🔴Ferrari -1.72
🥉🟠McL -1.52

❌Got slower:
🟣Alpine +0.08

-LEC was quicker than both Mercedes despite stopping one less time
-ALO matched PIA.
-VER: -0.28s/lap adv.

Race pace last year, for comparison
Only 15 drivers finished the race!
As no Williams driver covered over 90% of the race distance, it is impossible to evaluate their pace improvement, as the conditions would be too different for that

Which team surprised you the most today? 🤔

🛞TYRE WEAR (Per Team and Compound)

✅Best wear:
🔴Ferrari and🟢Aston (on both Hards and Mediums)

❌Worst (by far!):
🟢Mercedes on Hards
🟠McL on Mediums

🔵RBR's wear was moderate, and it didn't impact their excellent pace

⚠️The high wear ruined Mercedes' race

I realised that I made a mistake concerning McL: their race pace last year was 97.54s, and NOT 98.11s

So the team improved 'just' 0.95s/lap

All other values are correct, and the two graphs too

Thanks to those who pointed it out!

Gap to Race Winner

Only LEC and SAI led a lap in addition to VER (after the latter pitted)

In the last stint, LEC and NOR had the most laps on their tyres (27), HAM the least (15): that made him much quicker than both

Still, SAI was even quicker! (on 17-laps old Hards)

💡RedBull lifted through the 130R corner in the first 2 stints to preserve the tyres

The graph shows the speed trap (placed right after the 130R corner, which can be taken full-throttle but without DRS) values

You can notice 🟡RedBull’a bimodal distribution (two wide points: the upper one is their ‘true’ speed, the lower one is relative to lifting in the corner)

Haas reached 309km/h thrice there!🚀

SECTOR TIMES - Japanese GP

🔥Sainz's sectors were on fire in his last stint!

HAM was quick on 🟡Mediums (on a fresher set). However, Mercedes lacked consistency: notice the big gap in S1 and S2 between the first and second ⚪️Hard sets!⚠️

Increasing a car’s fuel efficiency from 5km/l to 10km/l will save you DOUBLE the money compared to increasing it from 10km/l to 20km/l 💰

Similarly, going 10km/h quicker in a slower highway segment will save you more time (and produce LESS additional fuel consumption) than doing the same through a faster segment ⏱

As @brrrake correctly pointed out, the same principle applies to F1 cars. Increasing one’s speed through the fast corners will save you less time, and induce more additional tyre wear, compared to doing the same through the slower corners. Red Bull Racing (and their drivers) seem to have grasped this concept: by lifting through the 130R corner (the fastest one in Suzuka), they managed to mitigate tyre wear for a modest loss of pace. 🛞

Can Machine Learning help F1 engineers predict an undercut attempt?🤔

@HearneLaurence contacted me about it, and later produced a model doing that!🤖

Solid lines: driver's pitting probability🔮
Dashed lines: the real pit.

The model predicted HAM pitting, and LEC covering it!💡

The plot has been taken from the Report of his Final Year Project.

The report is 114 pages long and very interesting: send him a message if you'd like to read it!

And if you're working for an F1 team you might be interested in his expertise.

Ferrari made TWO strategies work brilliantly: good strategy, tyre wear, and driving!👌

Check out the last stint (on ⚪️Hards): after pitting, SAI was 2s/lap quicker than LEC, who was managing his older tyres
LEC pushed more and more in that stint as the finish line got closer

Who will finish the season on top: Carlos Sainz or Charles Leclerc?🤔
