2015 Brazilian Grand Prix - Sao Paulo, November 13 - 15

Pit lane loss at Intelagos is 16.4 seconds, not 22.8. The time it takes to go through the pits is 22.8 seconds. The pit lane loss is that, minus the time it takes the other driver to drive the straight.

If lewis had a gap of 22.4 seconds, then he would have come out 6 seconds in the lead.

16 seconds is nowhere near enough to make a pit stop and rejoin ahead in the lead around Interlagos.

What he is saying, is the time the driver pitting looses is the time it takes the pitting driver to go from pit entry to pit exit minus the time it takes the driver on the track to do the same.

That 22.8 seconds is the amount of time the driver loses in the pitlane, not the amount of time he spends in the pitlane.

Hamilton's gap to Rosberg before his first pit stop was actually slightly bigger (by about 0.4 seconds), yet he still couldn't jump him in the pit stops.

Mods...have we somehow conflated Mexican GP into the Brazilian GP thread? Time to close the door!!

How did you come to this conclusion?
Nico did an in lap of 1:20.6 and an out lap of 1:32.3. He was averaging around 1:15.3 lap times in that part of the race. So he lost 5.3s on an in lap and 17s on an outlap, so I would say his pit lane loss was 22.3 not 16.4? or an I missing something?

Yes you are - during those two laps, Lewis drove up the main straight, beside the pit lane - and it took 6 seconds.

Yes, yes it is - the total time it takes to enter the pit lane, pit, and rejoin is 22.8 seconds. The time it takes to drive the main straight, and through the senna S is 6 seconds. That makes the pit loss roughly 16-17 seconds.

Incorrect, 22.8 seconds is the total time it takes to drive from pit entry to pit exit when a Mercedes crew is doing the tire change. If you read back in the thread, you'll see that this is exactly the context that this number is quoted in - that's how long it took Merc to do a pit stop. If you apply google for 3 seconds you'll find numerous sources for the 16-17 second pit lane loss at Interlagos.

The loss is extremely low at Interlagos because the pit exit misses out the first 3 corners of the circuit.

A Brazilian gossips site published a note stating that Lewis Hamilton will miss Brazilian GP due health issues.

This is not a site that follows F1, what makes the news even more weird.

Does anyone knows if it is true?

Wrong, the pit lane exit follows the exact same path as the Senna S. The pit lane exit at Interlagos is nothing like Montreal.

Yes, yes it is - the total time it takes to enter the pit lane, pit, and rejoin is 22.8 seconds. The time it takes to drive the main straight, and through the senna S is 6 seconds. That makes the pit loss roughly 16-17 seconds.

For starters, the entire first sector is about 18 seconds, and it takes MUCH longer than 6 seconds to drive the pit straight and the Senna S. It takes at least double that, about 12-14 seconds.

Rosberg crosses the start finish line at 0:07. He crosses the pit lane exit at 0:19. Tell me, does that look like six seconds to you?

Rosberg was 1.099 seconds ahead of Hamilton the lap before he entered his pit stop. He did his pit stop, rejoined, and the following lap they crossed the line, Hamilton was 22.4 seconds ahead of Rosberg.

Unless Hamilton found 7 seconds out of nowhere, it means that the pit stop time, logically, should be around about 23 seconds.

Hadn't realized until Lewis mentioned it in some promo video or something; Senna didn't win his home GP until his 8th attempt.

Can we please move all these posts about the 2014 GP to the 2014 GP thread?

Rosberg is really on form at the moment, but Hamilton has always been right behind him each time. Still difficult to predict who will be on pole, on form I'd go for Rosberg, but I can't help but think 5 in a row will have Hamilton champing at the bit to get pole this time out.

Hamilton's gap to Rosberg was 22.400 seconds when he crossed the line on lap 27, this was NOT ENOUGH to make a pit stop and rejoin ahead.

I just watched the race again; On the lap when Rosberg pitted he was losing a lot of time, locking up and as a result of this, the gap was below 1 second before he pitted to Hamilton (0627s just as he pitted).

On the live-timer, after Rosberg came out, the gap started out as 22.290s, 22.309s, 22.365s, 22.484s and then he was behind Button losing time (gap to Button 0.775s - gap to Lewis at that point 22.454s) - meanwhile, Lewis Hamilton just set the fastest lap with his 1:14.303. On the live-timer, the gap continued; 22.670s while Button was still ahead of Rosberg -> gap increasing. Then Hamilton lost it.

From this data, assuming identical pit-stop times, we can conclude that the gap, that was 0.627s when Rosberg pitted, came down by another 3 tenths. So would have been down to 0.3 at various points while both were on the track in different places. The only relevant questions - again, assuming identical pit-time for both - is if Hamilton could further reduce that gap by another 4 tenths. I unfortunately don't have the official sector times from those laps, but from the live-timer, it seems Hamilton was faster than Rosberg, despite the older tires. Perhaps not by much anymore, but it could have at least set him up to come out side by side with Rosberg.It was very close and if I felt there was a track where perhaps staying out a lap longer could make him jump someone attempting the undercut, I think this one was it (also helped by the fact Rosberg was marginally held up by Button).

We'll never know for sure. But a slightly quicker pit-stop (which I think Hamilton usually doesn't have anyway) I think would have sealed the deal.

Anyway, in regards to this weekends race; I think the driver into the lead after the first few corners will win the race. Overtaking is very difficult here and the chance to outperform soemeone who is undercutting you is probably not going to happen. Given that Lewis hasn't been the strongest at interlagos, I think I'll go with Rosberg for pole and win.

Yeah, that was what I thought. Mercedes team confirmed he is not missing Brazilian GP. Seems like that he changes the flight to Brazil and will arrive later. That is probably what generates the rumors.

[Roman]

To get back to topic - Brazil 2015 - the weather forecast for the weekend seems to be mixed, lots of rain and clouds, not much sun. Therefore I am still hoping for mixed conditions during race and qualifying. Does anybody know whether we can already begin to trust the weather forecasts at this point?

[F1NAC]

Conditions like 2012 would be good for me

Not for Hamilton.

Sorry I couldn't help it.

[turbof1]

If conditions are good enough, the track record will be broken. Last year Rosberg was only 2 tenths short, so in equal condition this year it shouldn't be a problem.
