HAAS TEAMMATES BATTLE ⚔️

The 'New entry' Hulkenberg outperformed Kevin Magnussen :
- He got P7 in Australia, getting half of the team's points in just one race
- He qualified ahead in 15 races out of 22
- He finished ahead most of the time

Who will be on top next year?

ALFA ROMEO TEAMMATES BATTLE ⚔️

Zhou got the same points as last year (6)
Bottas, instead, had a much worse season (10 points vs last year's 49).

Still, he performed better than Zhou this year as well, especially in qualiying.

Who will be on top next year?🤔

FIA banned the 'Inerter' (also called 'J-Damper') in 2022... but WHAT is that? And HOW does it work?🤔

I will give you the answers in this thread... and explain how it could have mitigated porpoising!👀

👇Read on, and get ready to learn!👇

Car suspensions have two components:

-Spring: applies a force proportional to its deflection➡️'Transmits' the energy of the bump to the car body
-Damper: force proportional to HOW QUICKLY it deflects➡️Dissipates such energy

F1 cars also had the Inerter... but what is it for?

The inerter applies a force proportional to the acceleration of its two extremities

So:
Suspension Deflection➡️Spring Force
Deflection speed➡️Damper Force
Deflection acceleration➡️Inerter Force

Invented in 2002 by a professor, F1 teams quickly adapted it to their needs!

A scheme:
When the suspension extends or compresses, the right ring moves relatively to the left ring↔️

Due to the thread profile, this produces a rotation of the inertial body (in🔴red)

This produces an inertial force proportional to the acceleration between the two rings.

How is this useful?

For any oscillation:
Acceleration: - Deflection*Frequency^2

1)The higher the frequency, the higher the acceleration vs the deflection
2)The acceleration has OPPOSITE sign compared to the deflection

So the Inerter 'contrasts' the spring at high frequencies!

So, the Inerter effectively makes the suspension softer at higher frequencies!

This is the 'holy grail':
-Engineers can use stiffer suspensions➡️More stable aero, more responsive car✅
-At higher frequency (kerbs/bumps), the suspensions soften➡️Less bouncing on unevenness!✅

A practical example:

Vertical axis: tyre load oscillation (bad!)
Horizontal: frequency

First, the engineer stiffens the suspension to improve the aero (solid to dashed line)➡️Problem: the peak increases

Then, they employ the inerter (bold line)➡️The peak reduces significantly!

FIA banned the inerter in 2022, on the grounds of cost-reduction🚫

The problem was that neither the FIA nor most teams predicted the porpoising
The Inerter would have been the perfect weapon to fight it! (By having different stiffnesses at lower and higher frequencies).

So that was the Inerter!🛠
Now you are one step closer to becoming an F1 engineer... or just a more tech-savvy fan!📚

Ever wondered how we get the videos of #F1 cars running over the kerbs?

Now you know!💡
(📸: alenpetak11 on Reddit)

Ferrari started the 2022 season with the most powerful engine (Honda was 2nd, then Mercedes and Renault)

They turned the power down after some catastrophic failures💥
This, coupled with Mercedes increasing the power after a reliability check, made their edge disappear📉

In the first race of 2022, I estimated Ferrari’s PU to be around 10hp more powerful than Honda, and 20hp more powerful than Mercedes

Wingtip vortices (2020 #F1 cars)

Spoilers generate downforce through the pressure differential between its two sides (lower side: lower pressure, upper side: higher pressure)

The two airflows (low and high-pressure) re-join at the wingtips, creating vortices

QUALIFYING GAPS👀

The field got much closer than in 2022!
Only🔴Ferrari got farther from pole (Still, not far off🔵RB)

🟢Aston was the most improved team. Still, 🟠McL matched it despite a terrible start

Mercedes: 3rd fastest

What's your 2024 prediction?🤔

2022 for comparison

The slowest team (Williams) was the same as in 2023, but it got significantly closer to the top: from a ~2.1s gap to a ~1.3s one!

I expect the team to be even closer next year! (as unsuccessful design choices are dropped and performance gain rate decreases).

The single fastest lap of the team was considered for each session.

📊 QUALIFYING PERFORMANCE
- Races 1-11: Aston was as quick as Merc, and Alpine quicker than McL.
- Races 12-22: Ferrari was quickest! Alpine was fighting with Aston.

DEVELOPMENT
📈 Improved: AT -0.52%, McL -0.49%, Williams -0.39.
📉 Got worse: Aston +0.52%, RB +0.23%, Alpine +0.11%.

Values are relative to each team’s quicker driver for each session.

QUALIFYING PERFORMANCE PER GP

🟠McLaren's improvement is clear: from 1-2% off the best to pole in Brazil! ✅

🟢Aston, instead, got progressively less competitive ❌

First 9 dry sessions: 7 RB, 1 Ferrari, 1 Merc
Last 9: 5 Ferrari, 3 RB, 1 McL.

Mercedes had stable performance.

DISTRIBUTION OF QUALI PERFORMANCE

On average:
🔵RB >🔴Ferrari >🟢Merc >🟢Aston =🟠McL

Ferrari was very consistent: they were never farther than 0.8% off pole!👌

Excluding Singapore, RB was the most consistent.

🟡Yellow Dots = Abu Dhabi.

McL, Haas, AT and Williams were quick!

Values are relative to each team’s quickest lap in the session.

Ferrari’s consistency in qualifying mirrors their inconsistency in the races!
