2021 Dutch Grand Prix - Zandvoort Sept 3 - 5

[Jolle]

the banking in the last corner is supposed to allow for different lines. If you're fast enough it becomes a corner again, but with downforce of F1 and the DRS opening later (that was not the initial plan) I think the F1 can take the line they want. Also the corner 1 (Tarzan) is flexible. But I am afraid the straight is simply too short to get alongside. is 650 m (1 km including last corner) enough?

If you have a good exit from Kumo (second to last corner), you’re able to floor it all the way through the last corner on the inside (easy flat with downforce) taking the whole straight on the inside and take Tarzan around middle of the track, taking a very late apex, not giving any real chance for an overtake

Hungaroring's main straight for comparison is around 740m of full throttle. Zandvoort is as you said around 1 km, however DRS zone will be around 100m shorter than in hungary, so I predict similar outcomes. Exception being zandvoort doesn't have further overtaking zones after T1, whereas hungaroring has T2-3-4 sequence. It's anyone's guess at this time.

Interesting to see what happens if someone has brake failure or an accident going into one of these banked corners. They will get launched upwards towards walls/banks.

That will be ok. Tarzan has a gravel trap “up hill”, corner 3 has a kink in front of it, reducing the speed actually going in to that corner and last corner they don’t brake.
Rolling the car at schijvlak is a real threat. If you go off there, it will be sideways into the gravel.

It would be madness to have the temperature sensors in a misrepresentative position because the ECU will not know the right temperature.
The engine mapping is extremely sensitive to air and water temperatures so the rumour is rubbish IMO.

Unless there is an algorithm compensating for that..

It doesn't quite work like that.
You know what, that rumour is so rubbish I won't even waste time going through the physics of how to achieve adiabatic cooling in the plenum.

Funny how this rumour rears its head again at a time when RedBull inevitably faces an engine penalty.

Why do you think this is only a rumor?

[WaikeCU]

Rumour has it that the WDC of this season drives for the team that has protested the most against the team of the rival WDC contender

There is a chance in to 3 if someone gets close in 1 and can stay close through 2. But it's a very small chance and I predict a coming together in to 3 because of that.

It appears, on first glance, to be a track that won't result in close racing in downforce producing cars. One needs to be able to follow closely in to and through 10 to have a chance in 11, to follow closely through 13 and 14 to have a chance in to 1.

Hopefully we're wrong and the track does work ok.

From the first corner (Tarzan) towards the straight before the hairpin (Audi-S), it’s al “natural weaving”, so no chance to get a nose in. Those kinks make it impossible to overtake there.

I guess it would depend on whether one can go WOT in the Arie Luyendyk when you follow in someones wake.

The FIA sensor is taking an average over time, the ECU sensor is near-real-time.

Doing flow simulation, I can believe that there can be warm/cool zones that can be designed into the plenum. After that, it is just careful placement of the 2 sensors to get the readings that are desired.

Looks like carnival time at Zandvoort! Should be fantastic atmosphere for the fans at the circuit.

Because you need full downforce at Kumo, there will be significant distance between cars going trough Luyendijk anyway. DRS will be fairly short, on the pit straight.
