The teams have found tyre wear at Istanbul is much less severe than expected.

Nick Heidfeld completed a 17-lap run on one set of tyres with little loss of performance, suggesting three or even two-stop strategies might be possible in the race.

Here is all the data for second practice in Turkey.

Longest stint comparison

  • The early signs are drivers won’t need to make up to four stops as Pirelli predicted.
  • Lewis Hamilton completed a 12-lap run with little loss in pace. Nick Heidfeld’s 17-lap stint shows how far drivers can go on one set of tyres.
  • These stints were done a ‘green’ track with little rubber on it. If rubber continues to build up over the race weekend it should help drivers makes their tyres last even longer
  • Once again Ferrari’s stint times look much more competitive than their single laps

  1. heh, giggle. Thought Mr Tires was covering himself. Ah well, three or two could well be the question here, an I guess the rain, who saves tires from qualifying, when said new tires are deployed, an who’s got full upgrades here and who’s saved them for Barcelona.

    1. Mr Tires

      Love it! Although you appear to have become North American (nothing wrong with that!).

      Yeh, we may see enough of a drop to give another China conundrum for the teams, or we could see teams getting it wrong one way or the other. That’s what I love about no re-fuelling, far more scope to change strategy during the race.

      1. Dammit! Tyres, with a why, much more asthetically pleasing.

        JESUS H CHRIST ON A BIKE EDIT FUNCTION,ah it doesn’t work.. it’s gone, did I just see the Keiths eye veiw of F1Fanatic?

    2. Only it will probably be dry tomorrow afternoon, with possibly a bit of rain during the race …

  2. I hope for rain and sun tommorow to see much better race at sunday!

    1. If it rains during qualifying everyone will have saved the soft tyres, thus equallying the advantages.

  3. What is the weather going to be like? Will it rain?

  4. Any thoughts on Sutil’s longest stint laps times, Pastor Maldonado’s and Alonso’s where similar, although their stints not as long.

    Have the Force made any improvements? I haven’t read anywhere that they’ve made any major upgrades.

    1. I was wondering about Sutil as well. He went two laps longer without going ‘off the cliff’, compared to DiResta.

      They announced they would have some updates. Maybe these were only on Hulkenbegrs/Sutils car?

  5. Did any teams use the Experimental Compound?

  6. looking close between RB, Mclaren and possibly ferrari. Hamilton was severely held up by a Virgin on his fastest lap

  7. Did any teams use the Experimental Compound?

    Any thoughts on Sutil’s longest stint laps times

    could be interesting to now abt it

  8. The teams used the new ‘super-hard’ compound tyre today, and it will be used at the next GP in Spain.

    http://www.autosport.com/news/report.php/id/91173

  9. yea but… only the “superhard” was used.. or the normal hard too?

    by the way, Sutil run in the keith’s graphic is on hard tyres (and low fuel) and is not useful for first stint race pace comparison. What abt adding sutil’s soft long run keith?

  10. yea but… only the “superhard” was used.. or the normal hard too?

    Both, and so it’s best not to read too much into what’s going on during practice sessions. But we all know that anyway, don’t we?

  11. lol
    the soft stints (last ones usually) are a good clue to understand race paces. sure, with approximations

    1. From what we can see by looking at wavy lines, Sutil will romp away from everyone in the race on Sunday, regardless of what happens in qualifying. Somehow, I don’t think that will be the case. :)

      Things like Maldanado not having KERS working and Kovalainens ineffective DRS muddy the picture still further. In fact there were a great many drivers driving cars that were not all that they could have been.

  12. This wasn’t a dry session, was it? Therefore we didn’t know what to expect of the tyres anyway?

    Buemi has carried his consistency into FP2 it seems. Though he did slow down much quicker throughout his stints.

    Good session to be a Mercedes engine!

  13. Does that mean that due to the lack of degrenation we may see 2-3 stops (if dry race) other then 3-4.
