United States Grand Prix 2021: Practice 1 team radio

Every message, in the order it happened

1. Sergio PEREZRed Bull17:32:02

   Engineer: Manage the pace. Stay off the curbs.

2. Fernando ALONSOAlpine17:32:45

   Engineer: Stop the car please, stop the car.

3. Daniel RICCIARDOMcLaren17:32:50

   Engineer: Red flag, Daniel, red flag with boxy slap.

4. Lance STROLLAston Martin17:33:20

   Engineer: Red flag red flag red flag boxbox red flag box red flag boxbox

5. Daniel RICCIARDOMcLaren17:33:50

   Engineer: So this red flag looks just to be an engine problem for Alonso. I expect they'll get that car moved quickly and we can get going again.

6. Nikita MAZEPINHaas17:34:55

   Nikita MAZEPIN: Copy. I have a lot of buffering on the helmet. It goes up like crazy, you see that? Understood.

7. Mick SCHUMACHERHaas17:35:45

   Mick SCHUMACHER: Ties dealt with slippery

8. Kimi RAIKKONENAlfa Romeo17:40:40

   Engineer: OK Kimi, we will have a green in 30 seconds, 30 seconds.

9. Esteban OCONAlpine17:41:17

   Engineer: I think we can look forward to push a little bit more on this out lap. Front temps are a little low.

10. Sergio PEREZRed Bull17:42:04

    Engineer: So the rear tyres are looking pretty good, just the front's a bit on the cool side.

11. Lando NORRISMcLaren17:42:50

    Lando NORRIS: Yeah, all good. My lights for recharge don't work. I don't know if I'm in recharge or not apart from when it says Recharge on my dash, but the lights aren't working

    Engineer: Okay, understood. We're checking now

12. Daniel RICCIARDOMcLaren17:45:25

    Engineer: I

    Daniel RICCIARDO: think they'll need a pretty good pull-down lap, so keep me posted on traffic. Copy.

    Engineer: So cars behind have finished laps. The car behind is Stroll. Gap two seconds.

13. Esteban OCONAlpine17:47:20

    Engineer: As we did lose that lap due to track limits at turn nine, there's quite a few cars in a similar position

14. Max VERSTAPPENRed Bull17:49:06

    Engineer: In terms of sectors, it's half a tenth to Hamilton in sector one. Same sector two time.

15. Lando NORRISMcLaren17:51:04

    Lando NORRIS: A lot of front and rear locking, I'll probably say rear locking the bigger problem, front locking only into turn 30.

16. Yuki TSUNODAAlphaTauri17:53:09

    Yuki TSUNODA: There is overheating already from turn 11. Copy.

17. Daniel RICCIARDOMcLaren17:55:01

    Engineer: Daniel we're going to stay out and do one more lap Lando is currently on a push lap

    Daniel RICCIARDO: 19

    Engineer: second ahead of you he can back off and potentially we practice getting a tow out of turn 11 if you want to abort after that that's okay

18. Carlos SAINZFerrari17:57:51

    Carlos SAINZ: Yeah, main limitation is too much rotation, high speed, and riding high speed, car feels super stiff at the rear, high speed.

19. Lewis HAMILTONMercedes17:59:18

    Engineer: There's a

    Lewis HAMILTON: lot of overheating. Yes, particularly.

    Engineer: Okay, copy.

20. Sebastian VETTELAston Martin17:59:21

    Engineer: The wind has come up a little bit, maybe 6 to 10 kph in the direction expected, so tailwind out of 1, tailwind into 15 and into 19.

21. Sebastian VETTELAston Martin18:00:51

    Engineer: OK, so tyre's still on the warm side but just need a bit of brake temp into 19 and 20. Ideally keep the pace up through the last two corners just to keep the tyres clean. Track is all clear ahead and behind at the moment.

22. Mick SCHUMACHERHaas18:01:56

    Engineer: Remember mode restart when it's off

23. Charles LECLERCFerrari18:02:25

    Engineer: And we have headwind into turn 1, 5 kph

24. Sebastian VETTELAston Martin18:03:11

    Engineer: So Sebastian, that lap was deleted for turn 9. Yeah,

    Sebastian VETTEL: copy. Lost the rear quite badly.

25. Sebastian VETTELAston Martin18:03:37

    Engineer: We're thinking a double cool.

    Sebastian VETTEL: Yeah, I think that's

    Engineer: a

    Sebastian VETTEL: good idea.

26. George RUSSELLWilliams18:04:43

    Engineer: He's on an out lap, he's on an out lap, you've got a clear run to the last corner currently.

    George RUSSELL: Interesting pace of his out lap.

    Engineer: Yeah, he's very slow.

27. Esteban OCONAlpine18:07:44

    Engineer: How's the balance?

    Esteban OCON: Yeah, I didn't feel a huge amount of extra grip unfortunately, so that's the first issue. Quite a lot of grip loss through the corner.

28. Nikita MAZEPINHaas18:10:11

    Engineer: How's the tyre? Is that big damage on the tyre? Hard to say. Okay, let's do a cool-down lap. Just watch out for the car coming through.

29. Pierre GASLYAlphaTauri18:11:21

    Engineer: Ok Pierre, how was that?

    Pierre GASLY: Yeah, not bad, just still for me it's too oversteery, I'm really rear limited and just like every time I go on power it's like I'm quite sideways. Like the rear generally is pretty weak.

30. Sergio PEREZRed Bull18:12:35

    Engineer: I

    Sergio PEREZ: think it will be quite hard to get it, how are the second laps for other people?

    Engineer: Leclerc's improved, 3 temps Vettel, 6 temps slower, otherwise not many people have done a second push lap yet.

31. Lando NORRISMcLaren18:13:00

    Lando NORRIS: Too badly flat spotted I got a box

32. Valtteri BOTTASMercedes18:13:28

    Engineer: And seeing quite a bit of separation in the rear wheels on entries. So think about reducing beamig and going up on the infantry. And let us know how much flap you want to drop.

33. Max VERSTAPPENRed Bull18:14:23

    Max VERSTAPPEN: I had

    Engineer: a

    Max VERSTAPPEN: really bad turn 1, because of the traffic.

    Engineer: Understood.

34. Esteban OCONAlpine18:15:32

    Engineer: So let's start to build some brake temperature at the end of the lap, the fronts are a little cool.

35. Antonio GIOVINAZZIAlfa Romeo18:16:01

    Engineer: And box, Antonio, box, box.

    Antonio GIOVINAZZI: We change the elements, we go for a new one.

    Engineer: Yeah, confirmed, we will change.

36. Antonio GIOVINAZZIAlfa Romeo18:16:12

    Antonio GIOVINAZZI: I need to stop, I need to stop the helmets, I don't know why it's coming out.

    Engineer: Copy Antonio, then we box this lap.

    Antonio GIOVINAZZI: We change the helmets,

    Engineer: we

    Antonio GIOVINAZZI: go for a new one.

    Engineer: Yeah, confirmed, we will change.

37. George RUSSELLWilliams18:17:18

    Engineer: Once you've done the double, you can just pull away gently. I can't.

    George RUSSELL: All right, what's

    Engineer: up?

    George RUSSELL: I can't give a double up.

    Engineer: OK, fine. No, it's fine.

38. Sebastian VETTELAston Martin18:18:38

    Engineer: Hamilton has just finished a fast lap on low fuel so he's either slow or in.

39. Lewis HAMILTONMercedes18:19:22

    Lewis HAMILTON: Did you say four tenths?

    Engineer: Four hundredths. Four hundredths of Valtteri's first lap.

40. Kimi RAIKKONENAlfa Romeo18:20:51

    Kimi RAIKKONEN: How long it takes to change the thing that we're talking about it? I don't know.

    Engineer: Uh... Impressive? Yeah, yeah, I know. Let me see with the time we have. He will be very tight. He's a quick change, but he will be very tight, Kimi. Very tight. We have only eight, nine minutes left. I'll stay out. Copy.

41. Sergio PEREZRed Bull18:23:37

    Sergio PEREZ: Driveability into 9 was quite good. I got a massive kick.

    Engineer: Copy that, we'll have a look.

42. George RUSSELLWilliams18:24:45

    Engineer: Brakes are all over the place, please give me feedback for beaming, I'll

    George RUSSELL: help get it in the window

43. Lance STROLLAston Martin18:25:32

    Engineer: So Leclerc ahead is used softly, think high fuel as well.

44. Max VERSTAPPENRed Bull18:26:05

    Engineer: Okay, we're looking at around three time laps to the chequered flag. There's a 15 seconds of margin on that. First laps for Checo on the hard tyre, 41.7, then a 41.5.

45. Sergio PEREZRed Bull18:26:58

    Engineer: Strat 3 when you can. Strat 3 for energy management test. Energy management test.

46. Valtteri BOTTASMercedes18:27:34

    Engineer: Clutch 1% deep, pedal was good.

47. Mick SCHUMACHERHaas18:29:29

    Engineer: Oh, I didn't see it. Okay, watch for Verstappen. He's Perez. Okay, watch for Verstappen. He's behind. Yeah, I didn't see. Okay, watch for Bottas. Do you have damage, Mick? Watch for Bottas behind. I guess so.

48. Sergio PEREZRed Bull18:29:56

    Sergio PEREZ: What an idiot, he's not looking at his mirrors.

49. Max VERSTAPPENRed Bull18:30:12

    Max VERSTAPPEN: Yeah, I didn't have any release out of, what is it, 13, 14?

    Engineer: Copy.

50. Daniel RICCIARDOMcLaren18:30:52

    Engineer: That's the checkered flag. I'm happy for you to keep pushing if you can get any clearer.

51. Sebastian VETTELAston Martin18:31:41

    Engineer: OK Sebastian, you can just back off now and make a bigger gap to Lance who's ahead, we'll do a stack pit stop, so just try to lose 15 to 20 seconds.

52. Charles LECLERCFerrari18:32:38

    Charles LECLERC: Yep, let's lead to the gate off Reynolds, be careful, there was one going down there I'll let you know when you're done

    Engineer: Copy
