The start has the capacity to be a lot more chaotic for Hamilton than the sprint race was. Cars behind as well as in front, and most will be starting on softer compounds than he is likely to run in the first stint.

That risk aside, if Hamilton makes places on the first lap (e.g. 7th, 8th, 9th), the podium is the absolute minimum race result.

I'm sure the new engine helps, but the fact Bottas was able to hold position relative to Verstappen on a degrading compound of tyre suggests Mercedes have the upper hand on this circuit. And Hamilton is in another league this weekend.

Outside chance we see Hamilton catch Verstappen and have to pass on track. Could be another coming together on the horizon.
They are expecting a 2 stopper so he may not have to. If he gets within 2-3 seconds with that advantage an undercut is almost a certainty.

I doubt Redbull would have noticed a 0.2mm difference on only one side of the DRS from tv footage but Mercedes didn’t. Not only that but I think RB went to the FIA about wing flex rather than the DRS slot gap.
Their DRS slot measured 0.2mm above the ‘hard maximum’ after qualifying, where would it be after the rest of the weekend? If that is caused by wear (that Red Bull may not be able to measure), how much flex in that element are they seeing at speed?
Where is this fabled 0.2mm actually coming from? Seems like someone just made it up and now everyone is happy to play along.

The stewards report makes no mention of it, only that it failed to achieve the required 10N at one spot. In fact, it is established within the report that the static measurement with no load applied is in within the 85mm requirement.

I don’t understand where the statement of possible wear or damage to the Mercedes DRS comes from. On footage taken before qualifying you can see that the round probe used for measuring the 85mm gap on the rear wing goes through completely and without resistance. All teams use this device and all teams know that the probe (circular device) should not be able to go through without resistance. So Mercedes knew before this before qualifying. There is footage of this, look for the right part of the rear wing as seen from the front

Is that a question or are you questioning the statement ?

Considering the rear wing not being returned to Mercedes yet and RBR’s request for information on Mercedes’ new flexing rear wing, which is why they were measured for so many cars after qualifying in the first place, makes me think we may see a new directive and measurement method for the final two races.

Can Ham pass other drivers with his car which is 27 km/h faster on the straights than everyone else? Stay tuned to find out.

Sorry, it was footage from scrutineering after quali., my bad. Could have been damage or wear after all.

Something is up, you don’t suddenly get that kind of speed from a fresh same spec engine. Smart to do it towards end season as there is very limited time to do something still.

Again, i point out the following, which does not get looked after enough.
RedBull filed the complaint, to which the FIA investigated and discovered the flaw.
The flaw is 0.2 MM. that is 0,24% difference, not even 1 %.
Media claims RB went to the FIA with a shitload of documentation about this difference.
HOW.
How is RB able to notice a 0.24% deviance in the gap. I call BS on this.
I also call BS that Max was able to notice a 0.24% difference in max allowed DRS opening,
just by touching and feeling and looking at the rear wing.

My point here is then how again is it possible that RBR knew this difference? It seems off to me.
And it's not like they were grasping at straws here panicking about the Mercedes car for their title chances,
being annoyed about the suspension gimmick.

It's claimed - though i dont know about the truth about this - that they had data that proved this.
How are they able to gather this data?

also, if we're talking about 0.24% difference in wing, then let's say that even if the wing would be open everywhere possible, then Mercedes would have gathered a 0.24% advantage. In lap time, that would mean Hamilton's top Q3 lap time of 1:07.934 would have been 1:08.097 at the worst. Max' best Q3 lap was 1:08.372, 0.275 seconds slower and Hamilton would have had pole still.

FIA stated that there was no foul intent by Mercedes. Yes, the simple truth is Hamilton's car did not meet requirements. So flatly said, the DSQ is 'correct' - offcourse RBR can gloat in this somewhat bad and sour tasting game to grab the title.

But i remain with the following: HOW did RB gather the data that provoked the FIA investigation?

on another level, i saw a vid passing of RB's DRS wing opening and closing due to the bumpyness of the track. I don't know if other cars have this as well, I assume they do. But if not, would that not also be an indication of the part being faulty? And to be fair, did it not open and close in the braking zone? Would that not provoke a DSQ too?

It’s a shame this had to happen. Must be the bumpy track around Interlagos causing this. Not sure what RW Bottas is running today, but Max’s RW was just dancing when the DRS was open. Just hope we won’t see RW failures today and tomorrow

It dances yes and it is clearly bending the rules, but crucially, it must have passed the 1 kg force test. Clearly RedBull has mastered the composite lay-ups and seems to have sufficient knowledge of Mercedes materials and the limits of deflection of those materials, be it temperature altitude, age etc. Genius move by Adrian to say the least.
example here.

again, i would like to see those RB data. 0.24% of a difference being able to be seen or measured by another team i would concider reaching beyond normality. if they have access to that data, that is amazing.

but if they do have that, then another question pops up: HOW come that Mercedes themselves didn't act upon that data? I really dont get it!

- As for the Sprint race itself:

Finally Bottas has kept his car in front of Max. He did outstanding today, should have done that always. I was not expecting this, i wasn't expecting him either being able to overtake Max either.
Also super impressed with Sainz, that was not only a mighty start, but also a great overtake in the corner showing some alfa male behaviour there. Great result and interesting for today's race.

Also extremely but absolutely extremely impressed with Hamilton's drive. Can't believe he managed P5 and that he finished just 1 second behind Sergio, if he had 2 more laps he would have managed P4!

With that in mind, very curious to see how tomorrow will unfold. Too bad he doesn't actually start P5, but P10 instead.

Let's hope Bottas manages to keep Max behind, and that Lewis once again can climb through the field and grab a podium. That would be extreme damage limitation.

Max is now 21 points ahead. If Max finishes P2 in Brazil and Lewis P3 and grab fastest lap, that will mean Max will have 23 points lead on Lewis. Lewis needs to grab 8 points over Max every race still to grab the title by 1 point, so that means a win and fastest lap with Max P2.

However, if Bottas against all odds manages to finish P2 with Lewis P1, that would build a room of 3 points for Lewis, and looking at Bottas now he could pull that off.

In other words, Lewis' title chances now depend on Bottas.

If Max however wins Brazil, that would mean Max will have a lead of 27 points and it's essentially game over for Lewis, as there's no way he can crunch 9 points over Max in the next 3 races as it's unlikely that Max will finish anywhere but P2. And again, just sacrifice Perez, Gasly or Tsunoda to deny Lewis the needed fastest lap point every race.

It's not just a fresh engine.

It's a fresh engine that only has to do 4 races so can be run constantly at a higher output.

I would hope the teams use good quality gauges for the set up which are regularly calibrated. If it failed the test it's all down to the teams set-up, build, design call it what you like. Limits are limits.
