United States Grand Prix2023 · Practice 1 team radio

EngineerAnd we can push in the hot lap on tires, which will be temperature limited on these compounds. Plus 5 on the dash if we can get there.

EngineerWe've got most people on the hard tyre at the moment, a few out there on mediums, so Haas on mediums, Ricciardo on mediums

EngineerThe car's good, it's just going to be working on your tyres. They're on the low side at the moment, so default at the moment is to do our two push laps.

EngineerSo it's about half and half on the tyres out there between the medium and the hard tyre.

Carlos SAINZOh my god, I think he didn't see me, but I request.

Pierre GASLYI'm liking a lot of grip in the low speed, turn one big like off rear, and ride through high speed

EngineerYeah, copy that

EngineerOkay Nico, we're actually going to box at the end of this lap so we can make a bigger change on the car.

EngineerNo need to box, we have an issue front left corner, so you need to cool the brakes in a straight line. Okay, very gentle into the box, do not use the brakes until you have to to stop the car outside the garage.

EngineerTurn one and the braking slightly later braking we need

Daniel RICCIARDOOkay, so I think you definitely feel a bit more front limited. Only time I'm really finding the rear is with ride.

EngineerAnd then that upsets the rear grip. Sergeant, four behind pushing. That's it. Okay, Sergeant, coming now. On which corner in particular, please? Box, box.

Carlos SAINZYeah, the car is jumping around a lot on the straights, it's for your info

EngineerUnderstood

EngineerAnd as a reference P1 is Hamilton with heart 37.4

Charles LECLERCRyan, start to work on the brake shape, only for turn 11. Very strange corner there. Let me know if you need any help with what's happening, but it should be clear.

Charles LECLERCRyan, start to work on the break shape.

Logan SARGEANTI need help turn 11.

EngineerA lot of

Logan SARGEANToverrotation on the Apex and Exit.

EngineerCopy, we'll have a look.

ZHOU GuanyuThere's absolutely no equipment, thanks.

EngineerCopy that.

EngineerYeah, George will just get into that tyre management and lift the coast. I'm just going to drive it as I see fit to start with, alright? There you go.

EngineerWe're seeing be about four just confirm that's intended recommendation was be about three

Pierre GASLYIs it learned or not because it doesn't show on the dash?

EngineerSo we think that mid to high 40s is a good lap time.

EngineerThis pace is good. Balance update.

Sergio PEREZMainly struggling with those diffractions.

Esteban OCONYeah, it's too real with the yellow.

EngineerYeah, copy that. Yeah, we're just discussing if there's anything else we can do for 12.

EngineerWe don't have time to do a decent run of sustainable laps now because the changeover took too long.

Sergio PEREZThe front is pretty dead into the low speed, I cannot stop it.

EngineerSuggest trying left toggle on for the next lap, left toggle on for the whole lap. No radio, radio is not working, repeat again. Yeah, left toggle on for the next lap, left toggle on for the next lap, test item. Copy.

Daniel RICCIARDOYeah, what was more evident then was Ride. Ride was quite bad, just down the straights and everything.

EngineerCopy that. In terms of balance, you think we went too far with the bar change? Box, box.

Daniel RICCIARDOYeah, yeah it seems so, yep. Agreed. Okay, box confirmed.

Sergio PEREZmain thing it's a front very light into the low speed and a bit of understeer into the into the high speed but the front is dead into into low speed breakings and i don't want to go on the mech battle yeah let's find another way to to out from them because we have healthy traction

Engineerokay well box rear practice pit stop and switch off

Engineerand oscar will be box this lap tests are breaking offline into turn one

EngineerCan I just do a radio check here? It should be better. Radio check. Sergeant Thor behind. Yeah, yeah. Better. OK, good.

Alexander ALBONPeak tyre grip was around 10.6

EngineerOK, copy, peak tyre around 10.6 So this will be a double call, target zero on the dash and happy to drop both axles

EngineerOrlando just experiment with lines through turn 13 to turn 16

Engineermaybe a slight shift in wind direction as well Max perhaps more of a tailwind coming out of one although it is shifting around slightly just keep your eyes on the flags still quite light around the lap

EngineerSuggest BMIC 2 and diff entry 1 step up for turn 1 only.

Charles LECLERCWhat is Varus trying to do?

EngineerHe's on an outlap with new soft I believe so he will push next lap

EngineerI

ZHOU Guanyudon't feel too much grip at the moment with the fire, but it could

Engineerbe true.

Nico HULKENBERGWe're hitting the front quite hard, that's for sure. I think we need a bit more air balance here.

EngineerSo,

Nico HULKENBERGwe'll try another half percent.

EngineerCopy that Niko, so we'll box now for flap adjust.

Max VERSTAPPENI see it gets pretty hot on the front end of it on

Engineerthe set

Charles LECLERCUpdate me on the margin, please, throughout the cooldowns.

EngineerCopy. It should be slightly faster than what you were doing with the heart.

EngineerWe need to do this lap 25 seconds faster than the previous. Check your clock. It will be 30.00 on the dot.

EngineerSo first car on a time-lapse to node reads at turn five at the moment. He is 20 seconds behind You've got one minute to get to the start finish line

Kevin MAGNUSSENIs that tight?

EngineerOne minute to go. It's reasonably tight

EngineerOkay, Fernando, so the start at the beginning of the session was seven under, seven under, and we'll be doing a left-hand side and two burnouts. I'll update you later.

EngineerOkay, launch procedure max, three burnouts, three burnouts, right hand side, gear one, and the low grip position. So three burnouts, right hand side, gear one, low grip.

EngineerBro,

Yuki TSUNODAwhat the f***?
