United States Grand Prix2021 · Practice 3 team radio

EngineerTrack is clear.

EngineerExpected the wind is about 15 kph tailwind out of one through the first sector.

Fernando ALONSOYou want DRS or no DRS? I'm happy not to use it.

EngineerI'm happy without DRS.

EngineerCheck soon,

Lewis HAMILTONColin.

EngineerOkay.

EngineerOkay, how is balance?

Fernando ALONSOAll is clear.

EngineerSo we're keen to go to torque 7 just as a check in his wind conditions, torque 7.

Nikita MAZEPINThe tyre temps are quite low, so I'm going to do a reasonably fast tap.

EngineerOur target temperature is the same, so I'm not too worried. It's OK for now.

EngineerSo, turn 11 was all because of Hamilton, or was the car also tricky there?

Mick SCHUMACHERIt was because of, it seems like the car was

Engineervery tricky. Okay, yeah, you had a big rear lock at the end, so we'll have a look at that.

EngineerAlright, so I think we should go to shape 2, and brake balance 1, click rearward. And the shape 2 will help turn 11, and then the brake balance 1, click rearward will be for the other front locks.

Mick SCHUMACHERCopy.

EngineerAnd what else was it like, what was the balance like in the 3, 4, 5, 6? I think the

Mick SCHUMACHERbalance there was actually quite okay, it was decent, but I missed turn 1 a bit. With the wide way around, I felt that the front was on

Engineerthe

Mick SCHUMACHERside to lock up,

Engineerso

Mick SCHUMACHERI just went straight. And then the last corner I had a bit of understeer, I think I'll just put the left toggle on for that.

EngineerYeah, it's worth a try. Okay, alright, we'll do another back off.

Engineerand compared to Sainz we could improve minimum speed turn 8

EngineerAnd Charles, manage at 35.7, improving in the last sector So

Carlos SAINZit's quicker than me in the last sector, yeah? Yeah All the way to?

EngineerOkay, positive on the brakes. We'll go for another charge lap.

Sergio PEREZYeah, and I also had some understeer at the end of the sector, last two corners.

EngineerOkay, copy that.

EngineerAoki, Gasly is using 3rd gear, turn 1 and last corner, so 1 gear more. Turn 12, 2nd gear, 1 gear less.

Yuki TSUNODAOK.

Pierre GASLYYeah, I find quite a lot of lap time when the balance is, the car feels a lot better, so I find a lot of time.

EngineerI think we have pretty bad land spots. Copy, so box, box, box.

EngineerMode 12 and Delta off. Mode 12, Delta off.

Yuki TSUNODAI think tyres are gone already from the sector 1, especially turn 8

EngineerUnderstood UB, let's try another one, there is no downside, we just try

Sergio PEREZOn my quick lap, I had a mega engine braking going into turn 1, right at the apex.

EngineerI

George RUSSELLfeel good, I've just been a bit over-optimistic.

EngineerCopy.

Engineereverybody is very slow even with the double slope and I'm doing mistake sector one I think we should box but give me your feedback is anybody improving on their second lap though? negative negative 810 slower did George do a second lap? he tried and he spurned in high speed copy box so you go in you go in make sure keep the brakes in the window no threat behind and the traffic like yeah yeah no threat no threat and gather the V-limbs after turn 11

EngineerOk, we are going to be box, box Happy, we don't need the setup change and we move to the soft And we do a couple of practice starts

Pierre GASLYYeah

EngineerCopy, you can keep the pace up Mode 12, charge off And we can go back to shape 3, Yuki is pushing now 3 behind, coming fast Ok, Yuki coming now, pushing, coming now

EngineerBox, box, box, box.

EngineerAs we have some time, would you like to do a practice start?

Fernando ALONSONegative. I'm happy with the start as well. Happy to box.

EngineerCopy, understood.

EngineerOkay, so box box Actually staying on track that will cool all clear behind So

Valtteri BOTTASthat

Engineerso we'll need some full throttle on the cooldowns

EngineerSo main loss to Verstappen is almost saying lap time to him but 3 tenths into turn one

Lewis HAMILTONRear is very poor.

EngineerOK, copy.

Charles LECLERCCopy, lap times please.

EngineerSo Sainz lap time 34.8. Same win as before, tail into 3.45, 15 kph and we need a good warm up on the brakes for last part.

EngineerSo what do we do? Layer up or down, no need of start, we can layer up or down.

EngineerLeclerc 3, 2, 1. Next pushing Russell 16 behind.

Charles LECLERCThe wheels were very difficult to manage on this lap.

EngineerSo we think this is a good spot, so let's focus on the tyres.

George RUSSELLAverage lap.

EngineerYes, decent going through 12.13, a little bit off maybe 6.7, so we'll box this lap with doubles, sort of a start in the pit lane, you've got cars around you on outlaps leaving the pit lane now. So much understeer, turn 8 traffic. Are we taking a second push? Negative, it's a first lap tyre. Coming through the pit lane. Three burnouts single, BPF end of pit lane and a launch. Can we check what the diff is doing in? No there's not, not with the tyres. But I'm still not really happy with the balance, would we have time to put a new import in there just to see what the diff would be doing if we tried something different, you know, going into qualifying. On a used set, yes. Yes, just to see. Right, three burnouts. BPF end of pit lane and a launch.

Charles LECLERCYeah, I don't know why, I'm struggling so much with the rears.

Pierre GASLYI think they have

Engineera

Pierre GASLYtiny bit more fluff for first sector, but the rest was a lot better compared to yesterday.

EngineerMax just eight hundredths faster in sector one, a match in sector two.

EngineerRed button on, red button on, we need to maintain temperature in the front brakes.

Max VERSTAPPENI'll have deleted.

EngineerYep, roger.

EngineerStill happy to let these rears drop a bit more, fronts are pretty good where they are now so try to keep the fronts where they are

EngineerThat would have been P1, do you have track limits at 9? At

Lewis HAMILTON9, yep

EngineerOkay, Daniel, we're going to do start practice at the pit exit again start practice at the pit exit So launch map on I want two burnouts and a second gear launch Remember the longer clutch phase

EngineerI

Pierre GASLYcaught a lot of rear-deck

EngineerCopy, on turn 11 was it the traffic or it was genuine tyres?

Pierre GASLYNo, I also put the push-tackle instead of pull Ah ok A bit of traffic

Pierre GASLYTurn 1 was good after, I don't know what's happened in high speed, the rear of the car was so so light I almost thought there was a problem because I just turned into turn 5, 6 and the car was rotating on its own So I don't know if it's just the rear tires which were outing or there was something else but a very big change of balance

EngineerWe have a strong tailwind in that last lap as well on these corners, we'll have a compare to the previous one Mode 12, charge off, box box through the pit lane for practice starts

EngineerI need to ask what happened.

Max VERSTAPPENI'm going to buy everyone glasses.

Yuki TSUNODAYou have to do something with the braking and the traction.

EngineerCopy, OK. Box, box for a static pit stop.
