2021 São Paulo Grand Prix - Interlagos, Nov 12-14

Since this is a technical forum. Here are some very notable technical details between Bottas and Lewis' car on the one hand and Perez and Max's car on the other. All four have a PU that differs in terms of lifespan/number of races.

This post is currently going viral and can be read everywhere except here. That's why I'm just posting it here.

Well he got his power figures the wrong way round for the Mercedes for start. And then using ball park figures for drag etc. is meaningless as the RB and Merc will be different there.

The numbers are the right way round. The calculation is the power that would be required to sustain the speeds shown given the drag characteristics chosen.

But either way they are clearly nonsense, no PU is producing 972 HP let alone KW at the speed trap. At best they might approach 1000HP briefly at the beginning of the straight.

As for the mass, it’s only needed to calculate acceleration and even then it’s at least 60kg too low since as well as the car mass they also need to include the rotational inertia of the wheels, brakes, transmission.

I get you, I really do. I’m just saying that now there is a precedent that if anything fails to comply with technical regs due to broken parts then in future we know what to expect.

So my guess here is that if the part passed before the session and failed later due to obvious damage, then it wouldn't be penalized. This would be akin to losing a bargeboard or a wing, or section of the car for example.

However if an item isn't tested (or cannot be tested) before the session and fails on the test, then it could result to a DQ. The example here is Hamilton's DRS flap. It wasn't FIA-tested before qualy so they cannot say it was legal at the start and only became illegal due to damage during the session. Another example is Vettel's fuel valve where there was no way of telling if the car had the requisite fuel remaining and it could not supply the required fuel for testing.

So does that Merc mill last for another 3 races? If it does, this title shifts to Ham.

Yep, Lewis has 2 as good as fresh engines for the coming 3 races.
engine output to full beans will have an exponential effect on everything.
more power to use in the corners, more power to use in the top speed.
with the suspension squatting that'll bring another benefit, AND let's not forget that
it will also cause less time lost during harvesting for the battery.

they should put up a big FU and reduce their DRS opening by 0.2 mm from the max allowed space,
and still beat the living daylights out of the opponent.

Anyway, as for the race

NOT what i expected but very very happy with the end result.
Amazing how much effort the FIA is doing to prevent that 8th title from Lewis and just give it to Max.

RB's gaining under the VSC, no action.
Max pushing off Lewis and a clear breach and it's not even 'investigated' - as it would demand a penalty.
Then weaving like a madman and then handing an useless black-white flag after Lewis passed.
DSQ from Q instead of a grid penalty and/or the chance to fix the wing like the chance RBR did get.

Amazing absolutely amazing driving of Lewis, this is why he's the GOAT.
That was utterly amazing. To be able to get from p20 to p5 in the short sprint race was nothing short of amazing,
then to start from p10 and WIN, despite all that was thrown, is absolutely legendary.

Lewis is smelling blood and he's going full on now. This is fantastic.

RB's gaining under VSC? Verstappen held back in the beginning of the sector and used all of his delta to gain at the end. Hamilton didn't do that, that's why Verstappen jumped him at the start after the VSC ended.

Brazil 2006 and 2021 are the most memorable races for me. Mega performance from the greatests champions.

No - he shows Hamilton (car 44) requiring much lower kW (700kW) to maintain a higher speed than Bottas (car 77) (971kW). It's a typo, of course, but it doesn't help an argument if you get the basic presentation wrong.

The whole things is flawed but it will help to feed a narrative that Mercedes are up to something a.k.a. "cheating.

The VSC periods are hard to judge as they can mess around with going slow then fast, and you gain more if you are in slower corners more.

A previous post said that Lewis' engine must be 65kW more powerful than Bottas' one.

Can't be easy to put that sort of power down without lighting up the tyres in 4th gear.

Think about it. 100 more horsepower under your foot without no prior experience in a car that was never set up for that level of power. It must not have been easy to drive.

Anyway. Back to reality. Lewis engine may be 15kW or so extra at MOST. His top speed was like down to deployment strategy.

Simply one of the best race weekends I have seen in over three decades of racing.

Some great driving, lots of controversy and some really salty attitude.

I cannot wait for the final three races.

You also have the option to inform the stewards before scrutiny, if you fear your part might have failed or got warn out. Probably not after you have started running in the session. But still, that option is also available.

Anyone got Max's onboard from the 'incident' ?

[siskue2005]

That was one of the greatest drive I have ever seen in 24 years of watch f1! Simply incredible

[bonjon1979]

Anyone got Max's onboard from the 'incident' ?

I bet they’re not going to release it. Because then it’ll be blatantly obvious and clear that max opens up the steering wheel and runs him off the road. You can see from how the front wheels change direction.

[illario]

I would have never ever in world of worlds would have believed that the day would come when i would close my eyes and start praying for Hamilton win.

[F1NAC]

Question. Dunno if it was posted here, but why didn't they do standing start after SC?

I’m hoping the crashalong YouTube channel does something on it soon.

I just can’t comprehend how Austria T4 and Brazil T4 incidents are different?
Austria T4 incident:

Reason
The stewards reviewed video evidence,
At entry of turn 4, Driver1 and Driver2 were side by side. Then on exit Driver2 was judged not to give Driver1 enough room and Driver1 was forced off the track.
