Belgian Grand Prix2019 · Practice 1 team radio

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

EngineerSo, Aero P4 5th gear cruise, please.

EngineerOkay, can we do DRS check please, DRS check and radio check as well.

Daniel RICCIARDOYep, radio is good.

EngineerLaune clear for me as well, turn 4.

EngineerAtlanta positioning wise you were ten long and five to your left

EngineerAnd a start after the exit on the right-hand side, and 5.20.

EngineerAnd confirming we are Boxerslap? Yeah, confirming Boxerslap

EngineerOK, 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.

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

Engineerand HPP 5 set position 10

EngineerOther 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.

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

Engineerthink

Valtteri BOTTASI'm going to learn from the next step how maybe

Engineerwe can stop for a flap. Yes, let's stop for a flap a chance. Plus

Valtteri BOTTASthree on the flap.

EngineerCarlos, how's the front wing?

Carlos SAINZI would say a bit overbalanced but a tiny bit, no major changes needed.

EngineerSo let's leave it where it is, one more timed lap. How

Carlos SAINZmany people on the softs or the mids?

EngineerIt'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.

Engineerand we need multifunction mix position 3, mix position 3

EngineerAnd 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.

Carlos SAINZYeah, no debris left on track, so we can go.

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

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

EngineerOK, 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.

EngineerAnd please could we have an aero P4 5th gear cruise up to turn 5.

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

EngineerOk, Carlos will be the only car on track.

EngineerOk Carlos, that's P2, recharge on is good

Carlos SAINZYeah quite slow down the straights there

EngineerA bit more front brake warm-up.

EngineerFor turn 8 suggest either left hand toggle or test third toggle turn 8 left hand or third toggle

EngineerSo the temperatures are looking low at the moment

Lewis HAMILTONThank you, sign as soon as possible, please keep the temperature

EngineerCopy Lewis, we're in State Bravair

EngineerOK, and how was the balance?

Daniel RICCIARDOIt 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.

EngineerYeah, OK, understood.

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

Sebastian VETTELJust as a remark, this tire set has some vibrations straight away.

EngineerOk, copy.

EngineerI

Romain GROSJEANdon'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.

EngineerOkay,

Romain GROSJEANyes, we're looking, we're looking. Oh, come on!

EngineerThe

Lewis HAMILTONfront tyre's not in the window.

EngineerProper push in lap. You

Sebastian VETTELmean proper mode raise?

EngineerYeah, mode raise and push please.

EngineerSo 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.

EngineerAnd 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.

Lando NORRISHappy to box.

EngineerYep, 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 NORRISNah, I'll go for one more. I'll just start the lap and then box at the end.

EngineerOkay, understood.

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

EngineerTorque 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 GASLYI have anyone in front of

Engineerme? Please repeat, please repeat

Pierre GASLYIs there any car in front of me?

EngineerPosition is good, position is good, both has 14 in front

EngineerAnd 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.

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

EngineerTop right modifier, please, Nico. Top right modifier.

EngineerLance 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

EngineerIgnore cool car warnings

EngineerWe stay mode race, 110kph available.

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