2025 McLaren F1 Team

[AR3-GP]

The RB19 and the SF24 had good tire management but they had tradeoffs. They lacked pace in qualifying trim because the car was slow to put energy into the tires (which was good for the race)

The MCL-39 seems very different. They are always very fast in qualifying and never suffer from cold tires. It is like a thermostat system where they put energy into the tires very quickly, but the heat source appears to "shut-off" once the tire reaches optimum temperature.

I feel like this is a little bit disingenuous. SF24 had an inherent qualifying weakness, while being plagued with development problems throughout most of the season. Why is it even being compared to RB19 in any way? The RB19 had 14 poles. MCL39 has gone 4/6 at the moment and their biggest quali gap was Australia, the rest have been super close. In terms of ratio from the races we have seen so far, the MCL39 is not *very* different compared to the RB19, qualifying-wise. Racepace-wise it’s not even close, the RB19 made the rest of the grid look completely hopeless.

From comments like these, you get the impression that some people just look at the final standings and completely ignore the gaps.
Or maybe people forgot how dominant RB19 was. It’s literally the most dominant car of the sport, statistically.

I don’t know what you are referring to. I was talking about car characteristics, not outright performance. Both of the RB19 and the late season SF24 had incredible tire management. It was even present earlier in the year for the SF24 (Japan) which was before they put on the bad floor in Barcelona (which they recovered in Monza where Leclerc won on a…1 stop strategy) . Ferrari always had cold tires on their qualifying laps. That’s the “reason” that they were slow in qualifying. It was a similar situation with the RB19. Drivers always complained about it.

The SF24 was a car that was somewhat on the “extreme” of tire temp balance. Issues that were exaggerated by aero issues that they spent most of 2024 trying to get on top off. That’s why it is not a valid comparison point against cars which were/are the benchmark of their respective fields.

And while the RB19 had a deliberate trade off for better race pace when it comes to difficulty in warming tires up in colder conditions (admitted by Newey himself), you don’t know that the same doesn’t apply to the MCL39. Nobody knows and nobody from McLaren has admitted anything in terms of strength or weakness from that perspective.

We know they’re exceptionally good (some might say too good) in managing tire temp on hotter conditions, but you do not know they’re not facing difficulties in warming tires up on cooler conditions.

Actually, by empirical evidence, you could make a claim for the opposite of what you’re saying, as their car loses a lot of pace against the competition when temps get lower.

Are we now comparing this Mclaren with the Red Bull of 2023 which was the most dominant car in history to the point that Perez an average driver came second easily?

I don't understand your arguments against the SF24. It was a car with great tire management with a qualifying penalty due to the way they achieved it. The same characteristic as the RB19. Simple point. It doesn't matter how quick the cars were.

It's not the Mclaren that loses pace when the temps get lower. It's the others that gain pace that they have lost when the temp goes higher and their tires overheat and fall out of the window. This is perfectly demonstrated in Saudi Arabia where Mclaren didn't gain anything between FP3 and qualifying but the others did. You can't regain what you haven't lost. These differences we are talking about are only a handful of degrees centigrade but as long as Mclaren can keep the temperature of the tire where it needs to be, they don't lose anything other than the negligible downforce loss coming from a very insignificant rarefaction effect at hotter temps.

- It is not a simple point, because the RB19 had a compromise that was calculated seemingly to perfection. SF24 had a weakness which seemed like a development oversight in comparison.

- They lose relative pace to the competition. Them gaining nothing when temps go down points to an inability of the MCL39 to get the same performance in the cooler conditions which can only be considered a tire-related problem. If everyone is gaining x amount of laptime when temps go down, but only one team doesn’t gain anything, it is that one team which should be considered the outlier and not the opposite …

The SF24 was a reaction to the tire eating SF23. Not an oversight.

Mclaren is the outlier because their car design is an outlier. It is a car which has much better control of the tire temperatures than the competition. That means they don't lose as much when the track gets hot. If you think Mclaren is struggling with cold tires, it is fiction. It's simply not what anyone is saying. Not the drivers, not the team, not any f1 journalist.

And you assuming they don’t struggle is also fiction.

Absence of proof is not proof absence. Just because they haven’t admitted to any issues does not make your assumption true.

You’re claiming the MCL39 is braking all norms despite them specifically struggling more compared to others when temps are getting low. Your expectation is for a team to be beaten in case of struggles, hence your assumption, but that doesn’t have to hold true. A car which has a significant performance advantage in certain track conditions can still maintain an advantage while struggling to get the most out of the package on other track conditions.

You’re selling your assumptions as fact. These outlandish claims that somehow the MCL39 is breaking past trends are empty words when you have nothing to back it up.
