2017 Brazilian Grand Prix - Interlagos, 10-12 November

I don't think hamilton will want to be shown up by max and with no more championship to worry about he will go all out. Vettle will want to make up for his start at mexico to quiet the critics, plus i think ferrari is going to be very good at this track.

It's going to be a cold race, may get tricky to put temperature in the tires. 11C max temperatures for the weekend.

are they racing in greenland?

I thought it was weird too, it usually doesn't get this cold this time of the year on account of it being late spring there. So far that's what I'm getting though, ~10-11 degrees C for the high.

Greenlands higher temps are -4 in the coming weekend - but windy.

Cold temperatures favour which of Mercedes, Ferrari and Red Bull more?

[NathanOlder]

Mercedes so far

Cold temperatures favour which of Mercedes, Ferrari and Red Bull more?

In my opinion, we have seen in Malaysia, the higher temperatures affected Mercedes, though it wasn't a problem in Baku, which saw the highest temperature of the season. As soon as the circus moved to Suzuka and the cooler temperatures welcomed, Mercedes did well. That sort of behavior would prompt someone to think that the cooler temperatures HELPS Mercedes.

The way I read is, cooler temperatures helps every team, but without the adverse impact cast by higher temperatures, Mercedes W08 stands out in ambient and LESS than ambient conditions. Whereas the performance of SF70H and RB13 doesn't get affected by the variation in temperatures. W08 seems to get sunburns in higher temperatures whereas the other two, seems to have born with natural sunscreen.

I wouldn't put the onus on ambient temperature, but rather how it relates to the features of the track. Mercedes has trouble when they can't get the temperature window in the front tires(over or under).

If it's a problem the cold temperatures will hurt the front left tire from coming up to temperature, and possibly the rear left's, but Interlagos has a lot of left turns so the right side should be fine.

That's not the forecast I am seeing! Am I missing something?

Agree temperatures in Baku were high, but most teams struggled to keep temperature in the tires on the long straight.

I think it might be a combination of the air temperature, amount of heavy braking zones, vs high speed sections, corners and the tribological properties of the asphalt used.

But overall the Merc seems to trive with lower temperatures.

Thanks for the explanation. I agree with your assessment.

If it is as cold as they predict, we should have a good opportunity to observe vortices from many of the cars this weekend.

The cooler temperatures definitely suit the Mercedes this season.

In Baku, the straights helped to cool the tires.

Because Merc had to compromise on the suspension this season, the Merc has had the tendency to overwork, and subsequently, overheat the rear tires. And it's the surface of the tires that is overheating, which causes the W08's rear to lose grip and start squirming all over the place. It becomes a really oversteer prone car and the power that PU is putting down does not help matters.

With lower ambient and track temperatures, overheating the surface of the rears becomes less of a concern, which really helps the car's balance and ability to look after the tires over the course of a single lap and during the race.

You're right, I'm getting +15 degrees now. Still going to be cloudy all weekend with some light showers, high of 26C.

You have to watch out that you look at the correct Interlagos. There seem to be several ones in Brasil. My forecast now says rain on Friday and Saturday with maximum temperatures around 25/26 degrees. Sunday dry with similar temperatures.

If this turns out to be correct we are in for an interesting race with no team having sufficient knowledge about tire wear etc….
