The British Grand Prix was the latest in a series of rain-affected events where one Ferrari driver called the conditions correctly and the other blew it.
Charles Leclerc was left to count the cost of a hasty switch to intermediate tyres when rain began to fall at Silverstone.His team mate Carlos Sainz Jnr, meanwhile not only avoided that mistake but chose arguably the perfect lap to switch to intermediates, taking around two seconds out of eventual winner Lewis Hamilton as a result.
This is the latest in a series of costly errors Leclerc and his race engineer have made in unpredictable wet weather conditions. It is the first since Bryan Bozzi replaced Xavier Marcos Padros as the voice in Leclerc’s ear.
The following year Leclerc threw away a potential win in Monaco with an unnecessary tyre change on a slowly drying track. Ferrari wanted both drivers to replace their worn intermediate tyres with fresh sets, but Sainz overruled them and remained on-track until the conditions were dry enough for slicks, moving him ahead of his team mate. Leclerc’s plight worsened when he lost more time pitting behind Sainz later in the race, but the initial call had already set him on course to lose victory.
Similar calls have caught Leclerc out in qualifying sessions. Later in 2022, as rain threatened at Interlagos during Q3, the Ferrari drivers again opted for different tyres. Leclerc was the only driver in the session to head out on intermediates and missed his opportunity to set a time on slicks when the track was dry enough. A similar situation occured during Q2 in Canada last year.
At Silverstone last weekend the difference between the information the Ferrari drivers received was stark. Sainz was given detailed guidance on the levels of rain at different parts of the circuit, while Leclerc’s information was less frequent and detailed. This led him to another costly tyre choice error.

As the field lined up on the grid the radar showed a significant band of rain to the west of the track which was around half an hour away from reaching it. However other, smaller showers were also passing close by, which occupied the engineers’ attention over the opening laps.
Leclerc started 11th, four places behind Sainz, but gained three at the start. The pair had Lance Stroll between them until Leclerc found a way by on lap 13, leaving just four seconds of clear air between the two Ferraris:

“We expect heavy rain now”
Sainz’s race engineer Ricardo Adami described the incoming rain using noticeably different language to Bozzi on Leclerc’s radio. He described the rain using the same colour codes seen on the weather radar. This shows light rain in cyan and heavier precipitation in green and then yellow.
After the race Sainz said they had worked on this before the race. “I had studied a lot the weather and everything with my engineer,” he said. “So I was very confident going into the race that we were capable of getting the calls right today. We did some good runs in FP1 and FP2 to measure the conditions, and today we were fully ready.”

“Right now it’s cyan”
Another difference between the two drivers’ radio messages was that Sainz was given specific information about how much rain was falling on individual corners or sectors of the track. This made him better able to judge how long he could survive on slick tyres on a wet track as his lap times rose by as much as eight seconds.
A further factor in Leclerc’s decision appears to be that he suffered a greater loss of grip when the rain fell than Sainz did. His lap times rose by around a second more than his team mate’s. Leclerc may have taken more out of his tyres while he was behind Stroll and therefore their temperature dropped more quickly as rain cooled the track.

“Wait a second before boxing”
Leclerc signalled early on lap 19 than he intended to pit. He hesitated at the end of the lap, then committed to his decision.
Sainz, who was being told the heavy rain was only falling in the final sector, stayed out.
Lap: 19/52 LEC: 1’45.868, SAI: 1’40.510 |
“You guys are doing a good job”
As Sainz realised he had weathered the worst of the initial band of rain, he offered his praise to his engineers. But as Leclerc left the pits on intermediates he saw the skies were lightening and began to realise his mistake.

After the race Leclerc admitted his decision was “clearly the wrong one” at the time.
“With the message I got and the information I had in the car, I felt like it was the right one,” he said. “It was raining quite a lot in [Stowe].
“I was told that in this lap the rain was going to be very heavy, so I stopped to try and anticipate. However the rain came eight or nine laps later. So that was obviously the end of our race from that moment on.”Sainz’s call was not only correct, but superbly timed. He came in on the same lap as Max Verstappen, and on the next lap most of the leaders copied them. But it was a fine call both ways: Oscar Piastri pitted two laps after Sainz and ruined his afternoon.
“We executed a perfect race,” said Sainz afterwards. “Honestly, all the calls were pretty much spot-on. All the tyres, all the radio calls.”
Leclerc is an excellent wet-weather driver, but his decision-making has often been found wanting in conditions like these. He and his engineer would do well to observe how the other side of the Ferrari garage is avoiding these mistakes that keep happening.

He fears rain, just like his engineers, past and present.
Even a blind man wouldn’t fit wet boots on a dry surface, but Ferrari has 1000+ employees to judge it.

It always makes me wonder. If rain is the great equalizer that allows the greats to really shine, and Leclerc has never shone in it, can he really be considered amongst the Verstappens and Hamiltons?
I think of this new crop (Russell, Leclerc, Norris and Verstappen) only Verstappen has really shown himself to be special in the rain.

Alain Prost in an all-time great but he was nowhere in the wet.

Norris is really good in the wet, in russia 2021 he kept hamilton behind on light rain when both had slicks, then he was left out on slicks for a lap on heavy rain and didn’t crash, he did the best he could in the circumstances, and whenever he’s given the right tyre he looks one of the best of the current field on the wet.
David BR (@david-br)
10th July 2024, 23:19
Agree with @esploratore1 that Norris is pretty good. Hamilton and Verstappen are so good because they’re both smooth drivers who balance the car well and have an extremely fine sense of adherence. Sainz is curiously excellent in another way, excellent track sensitivity and reactions. He nearly always drives better than Leclerc in the rain or when track conditions are tricky. Leclerc just seems to lack the same level of ‘feel’ of the track and tyre adherence of the others. Also maybe why he sometimes inexplicably just loses it and spins out of the race. Russell, I’m not sure. Kind of there in the rain without being brilliant.

Charles seems to have a win or bust mentality, or doesn’t see the bigger picture. I think his call to box was at least partly driven by losing 1s a lap to Sainz in the damp conditions. Verstappen was losing similar amounts of time to the front runners, and had trouble with his first set of tyres, but was smart enough not to panic and switch to wets.
Leroy (@g-funk)
9th July 2024, 14:43
The sad thing is that Ferrari will probably not learn from this and we will continue to see the same type of problems resulting from the communication between the pit wall and the driver. I think Charles puts too much faith in the pit wall telling him what he needs to know, whereas Carlos has clearly learned that he needs to get more raw information from them in order to make better decisions.

I’ve seen Ferrari do this many times. The driver is on inters and they say “it will rain in 5 minutes”.
In 5 minute the inters will be destroyed already!! What’s the point?
grat
9th July 2024, 15:18
If the inters lose 15 seconds total lap time in those 5 minutes, fine. Not pitting, you probably save 5-10 seconds. But when the inters lose you 35 seconds, and now you’re 15 seconds farther down the track than you would be for pitting, you have chosen poorly.
Ferrari keeps choosing poorly.
Edvaldo
9th July 2024, 15:44
But they will be unusable when the rain hits anyway. Ferrari did the exact same thing with Raikkonen in Malaysia ’09.
And they told him the exact same thing too.
“It’s not even raining”
“Wait a little bit. It’s coming”.
It came indeed. Way too late for those tyres.
Dex
9th July 2024, 15:37
It’s a lasting pattern. I don’t say that Sainz is necessarily the smarter driver of the two (probably is), it’s more about Leclerc not even trying to think for himself in some situations when he probably should’ve. Perhaps there’s more potential there, but he’s out of practise and probably lacking some confidence with making his own decisions too, so even when he dares to make a call he’s not really able to focus and think fast.
Brain needs practise too, not only when it comes to reflexes and memorizing tracks, procedures etc. Leclerc should probably work on his decision making process, as well as his capability to multitask. He’s had Sainz around for a while, it’s a bit silly that he didn’t try to emulate him a bit and steal some of his tricks. If he could that he’d become a complete package like Verstappen or Alonso, or at least Hamilton (who also prefers relying on his team and can make wrong decisions, but he can obviously judge the conditions on track with much more confidence).
In the end, not every driver reaches his full potential. It’s not written that Leclerc will ever become a champion, let alone a champion above Button or Rosberg category.
t1redmonkey (@t1redmonkey)
9th July 2024, 15:51
Sainz is really good at strategically thinking while he’s in the car and asking the right questions of his engineer, consistently shown this over his career. I said it before but he’s kind of in the wrong era, he’d have been extremely successful in the pre-radio F1 era where drivers had to make more decisions themselves without being spoon fed everything. There’s less chances to show this in modern day F1, but you can still see it paying off for him from time to time.

The golden rule, whether you need to make one pit stop or ten.
Be on the right tyres at the right time. With more than half the track OK for slicks, slicks it should be.
Ferrari had the information, but communication to Charles’ car was too poor.

SteveR (@stever)
9th July 2024, 19:27
Doesn’t seem so to me. With a number system, 1 for light, etc. it’s way easier to comprehend the differences in intensity. The color words just seem confusing and subject to mis-interpretation, especially over a car radio. Intensity 2 becoming intensity 3 just makes more sense than cyan becoming green.
DaveW (@dmw)
9th July 2024, 20:25
True but note that Sainz said he and his engineer studied the weather radar presentation. So they would have the same image in mind using the colors of how clouds were moving and changing. Sainz was able to visualize exactly what Adami was seeing in his screen. They really studied well for this.
Mooa42
10th July 2024, 1:43
@stever
If that was the only number system in use, then your approach makes sense, but it could add confusion in this situation, i.e. intensity 1 in corner 3 and intensity 3 in corner 1 with diff map button at 2 etc etc they already have too many numbering systems to remember.
I think they chose wisely and I suspect using cyan instead of blue was to differentiate between blue flags, and mentioning green/yellow together also to remove chance for misinterpretation, (although gold instead of yellow might have been a better option)
Regardless of system, a good understanding between driver and engineer is needed and needs to be refined, so Charles and Bozzi have some homework to do.

I do feel for Leclerc. He has had to deal with a whole bunch of issues that make his head-to-head with Sainz look worse than it probably should. But. This is not the first year this happens, and it’s not even the second.
At some point, if a driver cannot get the team to rally around him, to go that extra step to support him, to be on their toes at all times to do their best job then it’s not going to be good enough to beat the likes of Hamilton, of Verstappen.
As the famous quip from The Wire goes, Leclerc is having way too many ‘forth degree days’.
MichaelN
9th July 2024, 16:33
Forty degree days, that is. Thanks auto-correct.
But on that note, this is Leclerc’s sixth year at Ferrari. That’s a long time. That’s longer than Alonso was at Renault, longer than Räikkönen was at McLaren. It’s how long Vettel was at Red Bull and Hamilton was at McLaren.
I wonder if at some point a change of scenery will do him good.
Esploratore (@esploratore1)
10th July 2024, 2:16
Mmm, as you’re doing comparisons, he’s gonna reach the amount of years vettel was at ferrari when this season ends, as I recall he was there since 2015 and stayed till the end of 2020, so 6 full years.
Asd
9th July 2024, 16:34
I’m under the impression that in recent years whenever it’s a wets/inters toss up, the inters always win, and when it’s a slicks/inters toss up, the slicks always win. So basically the drier tyres always win.
RBAlonso (@rbalonso)
9th July 2024, 18:41
I’ve a few thoughts on this. Firstly, I’m going to afford the new race engineer some slack given the conditions did seem more marginal than the times suggest.
Secondly, making one bad choice is acceptable, continuing on for another 5 laps praying for weather that you know isn’t coming isn’t. Even a move to the soft for half a dozen laps would have been a better option.
Finally, and most importantly, why do Ferrari have contradictory information to each driver on the same lap? Leclerc chooses to box being told it’s 10 mins of bad weather when he’s at the wettest part of the track. Sainz is told it’s 2 laps. Leclerc’s then told it’s about to get heavier in 5 minutes and Sainz is told the intensity is reducing. Both engineers are looking at the same data and giving totally different verbal updates.
Fundamentally, they jumped the gun when Charles tyres were going off but it’s indicative of the same problems we saw under Binotto – the data isn’t being read clearly. That panic cost Norris the race against Bono and Lewis and also shows why Max and GP are so successful. Driver and engineer must be in tandem and on Sunday it was another pit wall horror show from Ferrari.
MichaelN
9th July 2024, 19:02
I hadn’t heard that about Sainz and Leclerc basically having two different ideas of how the rain would unfold. That’s indeed pretty bad. You’d think they would at least sort of sync intel on the pitwall before they make such important decisions.
Mooa42
10th July 2024, 1:56
@RBAlonso
They must trust each other implicitly too, like a rally driver and their co-driver. Norris has this issue too, the engineer needs to be strong and confident in what they are telling their driver, they must come from a position of having full faith in the information they are giving to the driver, if the driver doesn’t trust the engineer then it is unlikely to ever be a successful partnership. All well and good when everything is going smoothly but when the pressure is on, that’s when it really matters. GL and Max, both push each other and both push back too, Carlos and Adami have it too, I suspect coming from a rally background Carlos would have a lot better understanding than most about how important these relationships and how much trust is involved.
Richard
9th July 2024, 18:45
When everything is going great for both cars I’d put my money on Charles over Sainz but we’ve seen for years dating back before Ferrari that Sainz is just a more strategic minded driver out on the track and many times he’s thinking about what’s best for both cars not only himself. I understand keeping Charles, he is three years younger but Hamilton is 10 years older than Sainz and I just believe it was a mistake to swap Sainz out of that seat in favor of Hamilton. I don’t think it’s going to matter that much though as Bearman is likely taking that seat in ’26/’27 anyway.
Esploratore (@esploratore1)
10th July 2024, 2:20
Wow, if bearman takes the seat in 2026 it’s basically an admission going for hamilton was a bad idea, they wouldn’t keep him only a year if he were successful.

9th July 2024, 21:43
So, being given the wrong information (despite the right information presumably being available in the same garage) constitutes blowing a tyre call? Charles had an extra set of soft tyres due to missing Q2, and this would have been the perfect moment to use it – if he’d been allowed to do so.
Esploratore (@esploratore1)
10th July 2024, 2:23
No, indeed, I didn’t know he was given the incorrect information, but without knowing the situation I immediately guessed the team was to blame, it’s so ferrari-like to let drivers out on wrong tyres.
Agree the softs would’ve been a good idea in such situation, however he would’ve had to recover the pit stop time in few laps, before pitting again for inters, so I’m not sure if it’d have worked better than just waiting it out on the tyres he had on, but certainly way better than what they did.

Why is Ferrari telling Leclerc 10 minutes of this intensity rain and at the same time telling Sainz one to two laps (3 minutes or less)????
I doubt it has much to do with relaying the “colors” of the rain and more to do with the fact that they told Leclerc the heaviest rain would last 6 laps (10 minutes) and it lasted… one.
