Mexico City Grand Prix 2021: Practice 3 team radio

38 radio messages were recorded during practice 3 at the Mexico City Grand Prix 2021, across 14 drivers. Yuki TSUNODA had the most, with 8.

These are transcripts of real team radio audio, produced by speech recognition and presented as an archive rather than as edited prose. Radio is clipped and noisy, so wording can be imperfect. Each message is attributed to the driver or their engineer, and the original audio is playable in the archive.

Who was on the radio

Every message, in the order it happened

  1. Yuki TSUNODAAlphaTauri

    Engineer: Truck is clear behind, synchronize all the gears and good braking application, brand new brakes all around.

  2. Yuki TSUNODAAlphaTauri

    Yuki TSUNODA: The oil is so slippery.

    Engineer: Copy.

  3. Lance STROLLAston Martin

    Lance STROLL: So much oscillation on the limiter, we have to fix that.

    Engineer: Yeah, copy that.

  4. George RUSSELLWilliams

    George RUSSELL: Airplugs are not improved from my side.

    Engineer: OK copy that, so your radio is clear to us, just give us another radio check on the way round.

    George RUSSELL: I can still understand you but it's pretty distorted.

  5. Yuki TSUNODAAlphaTauri

    Engineer: So, Yuki, respect to yesterday, main loss section between turn 4 and turn 6, and in the high speed, but I guess you were careful in the first push lap.

    Yuki TSUNODA: No, just the oil is a lot, oil is a lot.

    Engineer: Understood, understood. Don't take any risk.

  6. Yuki TSUNODAAlphaTauri

    Engineer: Charge off and push.

  7. Lance STROLLAston Martin

    Engineer: Go one, go one, stay out, stay out, go one.

  8. George RUSSELLWilliams

    Engineer: OK George, we need to build front temperature so you can use DRS to turn 4 and to turn 12.

  9. George RUSSELLWilliams

    Engineer: OK George, next car back is Stroll, he's 13 back so no concerns on traffic. Snowda's now on a 19.7 so track is improving, so let's just go push at turn 16.

  10. Yuki TSUNODAAlphaTauri

    Yuki TSUNODA: Check engine 9, because I mistakenly touched it.

    Engineer: Copy.

  11. Carlos SAINZFerrari

  12. Carlos SAINZFerrari

    Carlos SAINZ: Yeah, nice script.

  13. George RUSSELLWilliams

    George RUSSELL: Advise on brake balance please, I feel a bit of a split on the fronts I'm loosing the fronts, please advise ASAP

    Engineer: OK, nudge her plus one, nudge her plus one

  14. Sebastian VETTELAston Martin

    Engineer: Turn 456 You can lean on the rears a bit in the high speed.

  15. Lewis HAMILTONMercedes

    Lewis HAMILTON: lost a lot of time in 10 copy

  16. Lando NORRISMcLaren

    Engineer: Okay, and a reminder, shifting and brake pressure application.

  17. Sergio PEREZRed Bull

    Engineer: There

    Sergio PEREZ: was a bit of chattering. There was a bit of chattering on the front tires in the high speed.

  18. Lance STROLLAston Martin

    Engineer: So let's focus on our tyres and brakes now.

  19. Sebastian VETTELAston Martin

    Engineer: So just so you know, Sebastian, the brake temps were a bit cool for Turn 1 on that last lap, in case you felt it. Yeah, I know.

  20. Max VERSTAPPENRed Bull

    Engineer: That's pretty P1, didn't look like the cleanest of laps but that's 4 tenths to Checo in P2. Yeah sectors look good. Sector 2, half seconds Checo, final sector a match. That was quite scrappy.

  21. Max VERSTAPPENRed Bull

    Engineer: Do you want any tool adjusts for the next lap, Max?

    Max VERSTAPPEN: No, it seemed quite OK, just on entry to some corners and a little bit on the edge, but let's see in another lap.

    Engineer: OK, understood.

  22. Lance STROLLAston Martin

    Engineer: Clear behind, let's focus on cooling the car and box box for a start.

  23. Daniel RICCIARDOMcLaren

    Daniel RICCIARDO: Just turn 3, just got quite a bit more of the apex settle up. Just double check the car when I come in front right.

    Engineer: Copy.

  24. Daniel RICCIARDOMcLaren

    Daniel RICCIARDO: Turn 3, just got quite a bit more of the apex sat-lap, just double check the car when I come in front right.

  25. Charles LECLERCFerrari

    Engineer: And for us you can push next lap?

    Charles LECLERC: Yep, I want to push next lap though. If you want we can do the pass through now, just to cool down the tyres as they are pretty hot.

  26. Lando NORRISMcLaren

    Lando NORRIS: Any particular reason I locked up or just too much brake pressure? Too

    Engineer: much brake pressure.

  27. Carlos SAINZFerrari

    Carlos SAINZ: You're only struggling high speed there, is this ok?

    Engineer: Understood

  28. Yuki TSUNODAAlphaTauri

    Engineer: Yuki, I think we need to adjust the flap, do you agree? It's too much understeer in turn 1.

    Yuki TSUNODA: I don't want to go back because it's just s**t tire.

    Engineer: Copy, we stay out.

  29. Nikita MAZEPINHaas
