The session, message by message
EngineerManage the pace. Stay off the curbs.
EngineerStop the car please, stop the car.
EngineerRed flag, Daniel, red flag with boxy slap.
EngineerRed flag red flag red flag boxbox red flag box red flag boxbox
EngineerSo 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.
Nikita MAZEPINCopy. I have a lot of buffering on the helmet. It goes up like crazy, you see that? Understood.
Mick SCHUMACHERTies dealt with slippery
EngineerOK Kimi, we will have a green in 30 seconds, 30 seconds.
EngineerI think we can look forward to push a little bit more on this out lap. Front temps are a little low.
EngineerSo the rear tyres are looking pretty good, just the front's a bit on the cool side.
Lando NORRISYeah, 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
EngineerOkay, understood. We're checking now
EngineerI
Daniel RICCIARDOthink they'll need a pretty good pull-down lap, so keep me posted on traffic. Copy.
EngineerSo cars behind have finished laps. The car behind is Stroll. Gap two seconds.
EngineerAs we did lose that lap due to track limits at turn nine, there's quite a few cars in a similar position
EngineerIn terms of sectors, it's half a tenth to Hamilton in sector one. Same sector two time.
Lando NORRISA lot of front and rear locking, I'll probably say rear locking the bigger problem, front locking only into turn 30.
Yuki TSUNODAThere is overheating already from turn 11. Copy.
EngineerDaniel we're going to stay out and do one more lap Lando is currently on a push lap
Daniel RICCIARDO19
Engineersecond 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
Carlos SAINZYeah, main limitation is too much rotation, high speed, and riding high speed, car feels super stiff at the rear, high speed.
EngineerThere's a
Lewis HAMILTONlot of overheating. Yes, particularly.
EngineerOkay, copy.
EngineerThe 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.
EngineerOK, 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.
EngineerRemember mode restart when it's off
EngineerAnd we have headwind into turn 1, 5 kph
EngineerSo Sebastian, that lap was deleted for turn 9. Yeah,
Sebastian VETTELcopy. Lost the rear quite badly.
EngineerWe're thinking a double cool.
Sebastian VETTELYeah, I think that's
Engineera
Sebastian VETTELgood idea.
EngineerHe's on an out lap, he's on an out lap, you've got a clear run to the last corner currently.
George RUSSELLInteresting pace of his out lap.
EngineerYeah, he's very slow.
EngineerHow's the balance?
Esteban OCONYeah, 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.
EngineerHow'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.
EngineerOk Pierre, how was that?
Pierre GASLYYeah, 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.
EngineerI
Sergio PEREZthink it will be quite hard to get it, how are the second laps for other people?
EngineerLeclerc's improved, 3 temps Vettel, 6 temps slower, otherwise not many people have done a second push lap yet.
Lando NORRISToo badly flat spotted I got a box
EngineerAnd 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.
Max VERSTAPPENI had
Engineera
Max VERSTAPPENreally bad turn 1, because of the traffic.
EngineerUnderstood.
EngineerSo let's start to build some brake temperature at the end of the lap, the fronts are a little cool.
EngineerAnd box, Antonio, box, box.
Antonio GIOVINAZZIWe change the elements, we go for a new one.
EngineerYeah, confirmed, we will change.
Antonio GIOVINAZZII need to stop, I need to stop the helmets, I don't know why it's coming out.
EngineerCopy Antonio, then we box this lap.
Antonio GIOVINAZZIWe change the helmets,
Engineerwe
Antonio GIOVINAZZIgo for a new one.
EngineerYeah, confirmed, we will change.
EngineerOnce you've done the double, you can just pull away gently. I can't.
George RUSSELLAll right, what's
Engineerup?
George RUSSELLI can't give a double up.
EngineerOK, fine. No, it's fine.
EngineerHamilton has just finished a fast lap on low fuel so he's either slow or in.
Lewis HAMILTONDid you say four tenths?
EngineerFour hundredths. Four hundredths of Valtteri's first lap.
Kimi RAIKKONENHow long it takes to change the thing that we're talking about it? I don't know.
EngineerUh... 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.
Sergio PEREZDriveability into 9 was quite good. I got a massive kick.
EngineerCopy that, we'll have a look.
EngineerBrakes are all over the place, please give me feedback for beaming, I'll
George RUSSELLhelp get it in the window
EngineerSo Leclerc ahead is used softly, think high fuel as well.
EngineerOkay, 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.
EngineerStrat 3 when you can. Strat 3 for energy management test. Energy management test.
EngineerClutch 1% deep, pedal was good.
EngineerOh, 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.
Sergio PEREZWhat an idiot, he's not looking at his mirrors.
Max VERSTAPPENYeah, I didn't have any release out of, what is it, 13, 14?
EngineerCopy.
EngineerThat's the checkered flag. I'm happy for you to keep pushing if you can get any clearer.
EngineerOK 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.
Charles LECLERCYep, 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
EngineerCopy
