Belgian Grand Prix 2019: Practice 1 team radio

Every message, in the order it happened

1. Max VERSTAPPENRed Bull10:00:54

   Engineer: Radio check. Radio check. Loud and clear. So nice and easy on the tyres.

2. Nico HULKENBERGRenault10:02:18

   Engineer: So, Aero P4 5th gear cruise, please.

3. Daniel RICCIARDORenault10:03:07

   Engineer: Okay, can we do DRS check please, DRS check and radio check as well.

   Daniel RICCIARDO: Yep, radio is good.

   Engineer: Laune clear for me as well, turn 4.

4. Lando NORRISMcLaren10:06:45

   Engineer: Atlanta positioning wise you were ten long and five to your left

5. Valtteri BOTTASMercedes10:15:39

   Engineer: And a start after the exit on the right-hand side, and 5.20.

6. Lando NORRISMcLaren10:16:10

   Engineer: And confirming we are Boxerslap? Yeah, confirming Boxerslap

7. Nicholas LATIFIWilliams10:18:59

   Engineer: OK, so track is clear, Hamilton is slow at turn 10, so we may get a flag, but for now, switches are good. And rear temps are OK, front's on a little bit of a low side, but it's go, push, go, push.

8. Antonio GIOVINAZZIAlfa Romeo10:21:39

   Engineer: So you have a lot of margin to push on the tires, we expect a strong outlap.

9. Valtteri BOTTASMercedes10:23:09

   Engineer: and HPP 5 set position 10

10. Carlos SAINZMcLaren10:25:49

    Engineer: Other cars have been struggling at the exit of Turn 1. Kubica spun there, Kvyat spun there. So that oversteer you had is common with a lot of other cars.

11. Valtteri BOTTASMercedes10:28:02

    Valtteri BOTTAS: There's a huge amount of understeer in the car in high speed, so I

    Engineer: think

    Valtteri BOTTAS: I'm going to learn from the next step how maybe

    Engineer: we can stop for a flap. Yes, let's stop for a flap a chance. Plus

    Valtteri BOTTAS: three on the flap.

12. Carlos SAINZMcLaren10:29:30

    Engineer: Carlos, how's the front wing?

    Carlos SAINZ: I would say a bit overbalanced but a tiny bit, no major changes needed.

    Engineer: So let's leave it where it is, one more timed lap. How

    Carlos SAINZ: many people on the softs or the mids?

    Engineer: It's roughly 50-50, roughly 50-50. So Perez on medium 147.8, Stroll medium 147.4 and Bottas medium 147.5. Other quick cars on soft.

13. Charles LECLERCFerrari10:31:15

    Engineer: and we need multifunction mix position 3, mix position 3

14. Lando NORRISMcLaren10:32:42

    Engineer: And continue to drive to the Delta, the virtual safety car is still deployed. It says I'm 22 seconds off my Delta, so what number do I need to stick to? Currently I think you're very safe to the Delta, I think you're very safe. But am I 24 seconds safe? It would appear so yes, I would keep driving at a reduced speed, so officially we need to be 40% slower. The virtual safety car is now ending, virtual safety car is ending.

15. Carlos SAINZMcLaren10:33:37

    Carlos SAINZ: Yeah, no debris left on track, so we can go.

    Engineer: Copy. Virtual safety car ending, track clear. So good warm-up on brakes. Cars should be in phase with you.

16. Nico HULKENBERGRenault10:34:20

    Engineer: And Nico, please could you press the OK button twice, please. Press the OK button twice. And confirming we have time for one timed lap.

17. Max VERSTAPPENRed Bull10:35:51

    Engineer: OK, that's put you P1 at the moment, BOTAS, similar time, in terms of track time, that's putting a 47.0, but that's on the medium, P2 is still Ricardo, 46.8, you were purple in sector 2 and sector 3, and we are 2.3 down in sector 1.

18. Nico HULKENBERGRenault10:37:33

    Engineer: And please could we have an aero P4 5th gear cruise up to turn 5.

19. Max VERSTAPPENRed Bull10:39:24

    Engineer: Okay, focus on your marks, it is a practice pit stop, and then kill the engine.

20. Carlos SAINZMcLaren10:48:49

    Engineer: Ok, Carlos will be the only car on track.

21. Carlos SAINZMcLaren10:53:08

    Engineer: Ok Carlos, that's P2, recharge on is good

    Carlos SAINZ: Yeah quite slow down the straights there

22. Carlos SAINZMcLaren10:54:03

    Engineer: A bit more front brake warm-up.

23. Carlos SAINZMcLaren10:54:39

    Engineer: For turn 8 suggest either left hand toggle or test third toggle turn 8 left hand or third toggle

24. Nico HULKENBERGRenault10:55:37

    Engineer: So the temperatures are looking low at the moment

25. Lewis HAMILTONMercedes10:58:01

    Lewis HAMILTON: Thank you, sign as soon as possible, please keep the temperature

    Engineer: Copy Lewis, we're in State Bravair

26. Daniel RICCIARDORenault10:59:21

    Engineer: OK, and how was the balance?

    Daniel RICCIARDO: It was pretty similar to the first run, not a whole lot of difference, I think some areas it had improved, so I wouldn't say any worse.

    Engineer: Yeah, OK, understood.

27. Charles LECLERCFerrari11:02:28

    Engineer: Where am I losing? Losing braking for 5 and 7 and also 8 braking 5 7 8 and also apex speed 12 13

28. Sebastian VETTELFerrari11:03:26

    Sebastian VETTEL: Just as a remark, this tire set has some vibrations straight away.

    Engineer: Ok, copy.

29. Romain GROSJEANHaas11:04:18

    Engineer: I

    Romain GROSJEAN: don't know what's going on in turn one of the braking it's all good and suddenly the front right decides to lock. Watch for the clear, watch for the clear.

    Engineer: Okay,

    Romain GROSJEAN: yes, we're looking, we're looking. Oh, come on!

30. Lewis HAMILTONMercedes11:06:08

    Engineer: The

    Lewis HAMILTON: front tyre's not in the window.

31. Sebastian VETTELFerrari11:10:33

    Engineer: Proper push in lap. You

    Sebastian VETTEL: mean proper mode raise?

    Engineer: Yeah, mode raise and push please.

32. Lance STROLLRacing Point11:11:53

    Engineer: So that was front tyre temperatures dropped too much and front brake temperatures too cold. So we just need to maintain more brake temperature if we can because that will keep the tyre and the brakes.

33. Nicholas LATIFIWilliams11:12:45

    Engineer: And use the overtake out of turn 4, non-DRS on the in-lap. OK, that's fine from our side. And go in-lap, track is clear around you.

34. Lando NORRISMcLaren11:14:38

    Lando NORRIS: Happy to box.

    Engineer: Yep, okay. If we box now there's more time to do a change. We do have time though if you want to do another time lap or open the lap.

    Lando NORRIS: Nah, I'll go for one more. I'll just start the lap and then box at the end.

    Engineer: Okay, understood.

35. Sergio PEREZRacing Point11:20:01

    Engineer: Hamilton pushing, leaving turn 1 now, Hamilton fast, it's 5 behind, so Hamilton fast 5 behind.

36. Pierre GASLYRed Bull11:21:40

    Engineer: Torque 1, back to Torque 1, and we need good work on the front tires and brakes again Keep working on your front tires Do

    Pierre GASLY: I have anyone in front of

    Engineer: me? Please repeat, please repeat

    Pierre GASLY: Is there any car in front of me?

    Engineer: Position is good, position is good, both has 14 in front

37. Nicholas LATIFIWilliams11:22:26

    Engineer: And how am I treating these laps? Like a power car or a push? You'll push initially to get the temps up and then I'll let you know. Copy.

38. Pierre GASLYRed Bull11:24:10

    Engineer: The track temp is slightly coming up a couple of degrees wind is still the same as before

39. Nico HULKENBERGRenault11:25:42

    Engineer: Top right modifier, please, Nico. Top right modifier.

40. Lance STROLLRacing Point11:27:01

    Engineer: Lance all you'll get is two timed in a row so it will be two timed laps but they'll be in a row so don't back off after the first one keep pushing and do a second one stay ahead of Hamilton stay ahead of Hamilton Hamilton's out lap and stay ahead of him he could be high fuel so stay ahead of him

41. Valtteri BOTTASMercedes11:27:54

    Engineer: Ignore cool car warnings

42. Sebastian VETTELFerrari11:28:25

    Engineer: We stay mode race, 110kph available.

43. Valtteri BOTTASMercedes11:30:04

    Engineer: So keep some temperature in the brakes, we're going to practice speed entry.
