Did you know that the air resistance alone makes F1 cars slow down at a rate higher than gravity?🤯

That's more than you get when stomping on the brakes of a road car... and the F1 driver isn't even braking! 😳

Here are the calculations: over 1.08g!
Absolutely mind-blowing!

The calculation stems from the fact that at the car's top speed (311km/h) the power of the engine equates to the power produced by the drag.

As Power = Force*Speed, and Force = Mass*Acceleration, we can obtain the acceleration value using the other known quantities.

THE CRAZIEST F1 PHOTO YOU'LL SEE TODAY!🔥

Cornering produces huge🔵Lateral forces (➡️Fy), equal to the🟢Inertial Force (-m*ay)

The resulting lateral load transfer increases the outer tyre🟣Load (⬆️Fz)

The rear left rim pokes out of the tyre, and the front right lifts!🤯

LATERAL LOAD TRANSFER
Corner to the right➡️The load transfers from the right-hand tyres to the left-hand tyres

LONGITUDINAL LOAD TRANSFER
Exiting the corner➡️The load transfers from the front to the rear tyres

Most loaded tyre: Rear Left
Least loaded: Front Right
The consequences are clear:

-The huge lateral force on the rear-left wheel shifts the tyre to the right compared to the rim. Static waves appear, too!
-The inertial force makes the chassis roll to the left
-The unloaded front-right tyre lifts
-The suspension becomes asymmetric

There are also other consequences (Camber, Toe variation, ...?) which are clearly visible from the image

🧐

You can notice how softer the 2019 car was compared to the 2022 one!

The 13'' tyres were softer due to the much higher sidewall, contributing to the roll.🛞

The Yamaha MotoGP Team has a new Performance Engineer: me! 🤩

I will work to extract the full potential of the bike, optimising the setup based on telemetry data, developing simulation tools... and more!🏍️

I cannot express how happy I am: I think that what I've found is the perfect match for me (as someone with a background in Motorcycle Dynamics🏍️)

And don't worry: the F1-related content will continue, as I love managing this page!🏎️

McLaren's new livery looks... pretty familiar!👀

Maybe they will surprise the competition with some out-of-the-box thinking... as Arrows did in Monaco 2001, with a crazy additional front wing to maximise downforce!💡

🏎 What makes these cars different, and each one faster than the previous one?🤔

This thread compares their performance: you can’t miss it if you’re a #F1 enthusiast!
👇👇

Formula 4
-Engine: road car engines (1.4l to 2.0l), ~160hp
-Mass: 570kg
-Width: 1750mm
-Wheelbase: 2750mm
-6 Gears
-0-100km/h: 3.5s
-Top speed: 250km/h (in low-drag spec)

Small, lightweight, raw: despite the road-car power, it would still destroy supercars in most circuits!

Formula 3
-Engine: 3.4l V6 N/A 380hp
-Mass: 550kg
-6 Gears
-0-100km/h: 3.1s
-0-200km/h: 7.8s
-Top speed: 300km/h (in low-drag spec)
-Max lateral acceleration: 2.6g
-Max braking acceleration: 1.9g [low, but official value]

A big step from F4: similar mass but over twice the power

Formula 2
-Engine: 3.4l V6 Turbo 620hp
-Mass: 755kg
-6 Gears
-0-100km/h: 2.9s
-0-200km/h: 6.6s
-Top speed: 335km/h (in low-drag spec)
-Max lateral acceleration: 3.5g
-Max braking acceleration: 3.9g

The game gets serious: almost unmatched downforce/mass and power/mass ratios!

Formula 1
-Engine: 1.6l V6 Turbo ~1000hp
-Mass: 798kg
-8 Gears
-0-100km/h: 2.2s
-0-200km/h: 4.4s
-Top speed: 350km/h (in low-drag spec)
-Max lateral acceleration: 6.0g
-Max braking acceleration: 6.0g

The queen of open-wheel racing: the downforce/mass ratio is unmatched

Summarising the main trends from F4 to F1:

- Cars get way bigger (Width 1750mm➡️2000mm, Wheelbase 2750mm➡️3600mm).

Therefore, the aerodynamics surfaces grow in area➡️More Downforce and Aero Efficiency.

- Better materials mitigate the weight increase.

- Engines get more complex and advanced➡️More power➡️Drag penalty is reduced➡️Possible to produce even more downforce through more loaded wings!

Notice that we started with 1.4-2.0l (Formula 4) and ended with 1.6l (Formula 1)

The displacement is similar, but:
- Much higher turbo pressure and combustions temps -Energy recovery (both kinetic and thermal)
- Higher Fuel flow rates
make F1 engines over 6 times more powerful! 🤯

📚 I’m sure that you now have a much clearer picture of the differences between these open-wheel racecars (And why the performance difference is so big!)

I’m a Mechanical Engineer and Vehicle Dynamics Researcher: follow my page @FDataAnalysis to understand Formula 1 better! 🏎🤩

In #IndyCar, aero setup gets even crazier than in #F1!🛠

Top: Low-Drag Spec (speedways)
Bottom: High-Downforce (road courses)

In the second case, rules allow ~100hp more: despite that, the terminal speed gets SEVENTY km/h lower!

Drag doubles: (675/575)(390/320)^3 = 210%!

These are the 2015-2017 Honda Aerokits, that’s why the aeroscreen is missing.

Formula 2 cars now have a Super Formula-inspired DRS plane

Which series is quicker, though?

- Formula 2 have a larger engine➡️70hp more, but cars are also 60kg heavier
- Dimensions are almost equal

Overall, @SUPER_FORMULA is quite a bit faster due to its superior downforce!

Pirelli C0: the compound we never saw in 2023

Pirelli chose 3 compounds based on track characteristics, from C1 (Hardest) to C5 (Softest)
But did you know that an even harder C0 compound existed?

It was never used: the C1 was deemed durable enough even for tracks like Suzuka.

On pure pace, the 2014 Mercedes W05 was FAR more dominant than the RB19!

Bahrain, SC restart: HAM on hards pulled a 7.1s gap to PER in 2 laps... while battling with ROS!

- Excellent chassis/aero.
- Godly engine (7 Mercedes engines in top 9), despite de-tuning to hide performance!
