Highest Percentage Wins in a Season (Drivers)
🥇Verstappen 2023 - 86.36% (19/22)
🥈Ascari 1952 - 75.00% (6/8)
🥉Schumacher 2004 - 72.22% (13/18)
This year Max Verstappen beat a 71-year old record!🤯
Ascari's record is impressive considering old #F1 cars' bad reliability.

Ferrari SF-23 (Top) vs SF21 (Bottom)🔎
Notice how different the shape (and size) of the bodywork is!👀
The 18'' rims made the 2023 tyres' diameter larger (despite the thinner sidewall): 660mm➡️720mm
The next comparison will be based on your comments: choose two #F1 cars!🤩

The most powerful F1 engine ever? The tiny 1500cc 4-cylinder 1986 BMW M12: over 1400hp in qualifying!🔥 Power is estimated: no dyno could accurately measure over 1000hp!💡 The Benetton reached 352km/h in Monza, with much worse drag (and grip) than current…
The inline-4 layout of the BMW engine gave it a clear advantage over the V6 engines used by Ferrari and Renault:
1 fewer turbos, 2 fewer cylinders, 8 fewer valves➡️lower frictional losses➡️More power and better reliability.

F1 vs MotoGP Aero
In F1, wings make you corner quicker
In MotoGP, cornering might get worse!😳
F1:🔵downforce increases the🔴tyre load➡️more grip (higher lat. accel. ay).
MotoGP:🔵"down"-force has a horizontal (centrifugal) component, pushing the bike out of the corner!
🔵Downforce acts on the bike midplane
⬇️
-The tyres🔴vertical load increases (good).
-More🟣lateral tyre force is required for a given lateral acceleration (bad!).
At best, the two effects cancel out.
At worst, cornering gets worse as the friction coefficient μ decreases! 📉
So, why do MotoGP engineers add wings on the bikes if they cause additional drag while potentially making cornering worse? 🤔
Mostly to limit wheelie: that's the limiting factor out of most corners, and not the rear tyre grip! 🏍
Braking improves too.👌

In '05 and '06, Alonso became champion with Renault, showing a driving technique never seen before... and no one has used it since then!👀 He used very high steering angles to manage the front tyre temperatures in a unique way🛞🔥 👇Curious already? Read on…
At the time, there were two tyre suppliers; Renault was equipped with Michelin tyres.
In 2005, pit stops were banned! Drivers had to complete qualifying and the race on a single tyre set. Suppliers provided very hard and durable tyres... too much for a qualifying session!

ALO's Renault was gifted with excellent traction.
This improved further in '06 when the team introduced the legendary 'Mass Damper': a mass connected to the chassis through a spring, tuned so that the mass itself oscillated instead of the car when over kerbs!

When the rear grip is higher than front grip, understeer occurs: the front tyres slide more than the rear ones, making the car widen its trajectory.
On corner exit, the longitudinal load transfer can make this worse as the vertical load shifts from the front to the rear tyres.
Alonso found a clever way to turn this into an advantage:
He approached the corner normally, then turned the steering aggressively much sooner than the corner apex, inducing high front slip-angles (the angle between where a tyre is steered and where it's effectively going).

Doing so produced a significant increase in the front tyre temperatures!
The higher the slip angle, the higher the thermal power produced.
He mainly used this technique at a lower speed when the downforce was lower; the wear was reasonable and keeping temps even more critical!
This technique was not seen again after '2006: Michelin retired from F1, and the tyres of the remaining supplier (Bridgestone) didn't perform as well when subject to extreme slip angle values.
This peculiar characteristic of the Michelin was due to their very stiff construction.

Summing it up:
-Very stiff, durable and slip-happy tyre
-A car with excellent traction
-A creative team (introducing the mass damper)
-An adaptable and clever driver
⬇️
Combined in making this unique driving style possible!
Pat Symonds once said that one of Fernando's main assets is his ability to ''drive around" the car's problems
In his opinion, this was a fault as well, as Alonso apparently neglected setup work, stating: "I can drive it anyway"!🤣
That's it! I love this tech detail - let me know if you knew it before, and I hope I have taught you something new today!

INDYCAR PUSH-ROD REAR SUSPENSION

🟡Push-Rod compresses, making the🔴Rocker rotate, compressing the🟣Main Spring.
When the two wheels move in opposite directions (Cornering, Case 2), the🟠Anti-Rollbar twists, stiffening the suspension!

In 2014 in Barcelona, Caterham’s F1 car was SLOWER than their GP2 car! 🤯 -1.30.3 for the F1 car -1.29.8 for the GP2 car(0.5s faster!) F1 cars became terribly slow in ‘14, and Caterham’s car was terrible all-around! I explain this strange result in this…
F1 cars became terribly slow in 2014.
This was due to:
- New PU➡️Significantly increased mass (+49kg over 2013);
- Lower peak and mean power than the already weak V8s (Considering Caterham’s Renault PU: around 750hp+80hp of KERS for V8, around 600+160hp for V6s);
- Narrower front wing.
