2021 Mexican Grand Prix - Autódromo Hermanos Rodríguez, Nov 05 - 07

[RZS10]

So there's already four drivers starting at the back of the grid: Yuki, Lance, Lando and Esteban ... i fully expect further penalties

[Mansell89]

Merc can’t quite match the RBR in the middle can they. I’d worry about McLaren and Ferrari getting close if both of those raise their game (they’ve both looked too bad to be true to be honest)

[Zynerji]

With lack of downforce W12 is experiencing relative to RB16B, they would be in for a troubled GP with tyre deg.

You have that completely reversed, Max was the one doing 2 cool down laps. That's a strong suggestion that he is working the tires hard!

Could be the brakes instead of the tyres tho...

If they need 2 laps to cool the brakes down at the speed of their cool down lapse, there's no way their brakes will survive the race.

I mean, Jenson is the one that said it during the broadcast. He said brake temps being very high are common here.

[Sieper]

Qualy run requires much harder braking. I go with Jenson. In fact, Perez second run was the fastest. Tire temp is important, it mustn’t be too low.

[Dee]

Wasn't Max's fastest time done on his first lap? He just had issues with the car at the end of the session, back wing was tapped together and parts fell off during the lap and the practice start

[politburo]

At this rate. Hamilton needs to aim tor P2 even if its 0.5s a lap slower in Q3.
If he can pick the start and stay ahead of Max on the straights he has a chance to win.
Redbull may just repeat what the did in Texas but Mercedes need to be ready to pit earlier.

Was tyre deg a factor last year?

No I think tyre deg is low. Fastest strategy was 1 stop, hard tyre went 50+ laps for some drivers. Those who stopped twice just ruined their race - Ferrari in particular, who had a Leclerc 1, Vettel 2 early in the race but somehow managed only one driver on the podium, that driver, Vettel, stopped once. Undercut is very powerful.

You missed my point, cool down laps are 40 to 45 seconds a lap slower. If you need 2 of those, there's no way Your brakes, are going to survive a race distance running laps that are only 5 to 10 seconds a lap slower than your qualifying pace. Keep in mind at race start you're going to have a lot more fuel on board at that is also going to work the brakes very hard.

Is this really true? Cars are much heavier in the race. You won't see the same peak deceleration, but top speed into braking zones will be similar (at least for quite a few turns) and corner speeds will be lower, so you have the same or higher speed delta with higher mass for most braking zones. Way more energy and therefore heat into the brakes in a race I'd say.

Kinetic energy is 0.5*M*V^2 so calculating the energy you need to dissipate is pretty easy.

The much harder part is, determining how much of the braking force is coming from aero drag, the engine, and the brakes.

[Wouter]

Well, this is looking good. Perez has finally found a good setup. Great for his home crowd!
And rookie Yuki with his new PU! Between Sainz and Ricciardo!
Hope he does well in quali.

[bosyber]

You do realize that both Verstappen and Hamilton had faster laps deleted right? Still, like last time out, Perez being on/near Verstappen pace in quali trim is definitely a good step for him and Red Bull.

[search]

they didn't have any quick laps deleted today. That was two weeks ago in FP3
