After nothing however first and second locations for Max Verstappen for the reason that F1 summer season break, the Mexico GP weekend is more difficult for Purple Bull.
Though the Dutchman topped the timesheets on Friday, he instantly admitted that the lengthy runs weren’t adequate: “You’re not going to win like this,” he mentioned. A day later, that evaluation appeared appropriate as Verstappen needed to accept fifth place in qualifying and concluded that “nothing labored” with the RB21.
That final comment matches with the continuing seek for a greater set-up path between Friday and Saturday’s periods.
“You’re all the time engaged on that, in fact. However yeah, we tried every part till qualifying and nothing actually made it higher,” Verstappen mentioned, earlier than including that one set-up path gave him a barely higher feeling than one other, however the outright tempo didn’t come.
That will sound shocking at a observe the place Verstappen has already gained 5 occasions previously, however he sees it in a different way: “These had been completely different occasions. Final 12 months issues did not work, and that is the final reference I’ve. And now issues aren’t working once more.”

Stella’s concept: Cooling variations between McLaren and Purple Bull
Naturally, the query arises – what precisely is Purple Bull combating? As all the time, it is a mixture of things, although McLaren group principal Andrea Stella supplied not less than one concept on Saturday night.
“It is a circuit during which the standard of your cooling system is vital,” mentioned the Italian. “If it’s essential to compromise aerodynamics to realize sufficient cooling, then the lack of aerodynamic effectivity will be fairly fast.”
It factors to the truth that the extra groups have to open up their bodywork with extra cooling inlets, the extra it impacts the aerodynamic efficiency of the automotive.
In keeping with Stella, Purple Bull is having to make better compromises in that space than McLaren – one thing that’s visually obvious from the bigger cooling openings on the RB21.
“Right here we see the return on the investments that we’ve executed for the 2025 automotive on the cooling system itself, the engineering and the know-how,” Stella added.
Consequently, McLaren appears much less depending on extra openings within the bodywork, which can provide the group a sporting benefit at venues like Mexico. Stella believes it’s not less than one purpose behind the distinction in efficiency in contrast with latest weeks, though he’s cautious about drawing far-reaching conclusions for the upcoming races. “Mexico will not be a spot, as an instance, to evaluate a automotive, as a result of there could possibly be a cooling implication that may decide the efficiency considerably.”

A vicious circle? Sliding and tyres overheating
Though cooling is undoubtedly a key consider Mexico, Verstappen believes it’s not crucial purpose for Purple Bull’s troublesome weekend thus far. Throughout his Dutch media spherical within the paddock, the reigning world champion pointed to a different subject – the Pirelli tyres overheating.
“I believe we have not been excellent all season with the tyres overheating. And that is truly fairly a giant downside right here. At altitude, in fact, you begin sliding after which the tyres warmth up so much instantly. It does not swimsuit us, that is very clear.”
It’s a vicious circle to some extent. All drivers are working high-downforce wing ranges, however because of the altitude, that also produces much less downforce than in Monza. Consequently, mechanical grip turns into extra vital, and it makes it simpler for automobiles to start out sliding as effectively.
That’s precisely what Verstappen is referring to. As soon as his automotive begins sliding, the tyres overheat – even over a single flying lap. The ensuing lack of grip causes much more sliding, which in flip will increase overheating. It’s a self-reinforcing course of, and in Mexico, it’s notably punishing.

Marko admits: “Perhaps we went a bit too excessive with trip top”
Lastly, a 3rd issue have to be talked about: trip top. Verstappen struggled notably within the second sector, primarily by means of Flip 9, the place he had a number of moments. Requested what was going improper within the few high-speed corners of the Autodromo Hermanos Rodriguez, Verstappen replied: “Properly, watch the onboard, flip up the quantity, and you will hear what’s occurring there.”
Verstappen was referring to the Purple Bull automotive bottoming out in Flip 9. In keeping with Purple Bull advisor Helmut Marko it is the results of going a bit too excessive with the trip top alternative this weekend. “The trip top is essential, however within the center sector we had been maybe a little bit over the restrict,” admitted the 82-year-old Austrian.
Experience top is vital to maximising these floor impact automobiles and sealing the airflow beneath the ground, however going too far brings two dangers: if the plank wears down an excessive amount of from contact with the observe, groups threat a DSQ; and extreme bottoming compromises the trip as effectively.
It was that latter that hindered Verstappen in qualifying. Due to Purple Bull’s dangerous trip top alternative, each bump may trigger a second of imbalance – which occurred a number of occasions in Flip 9.
A mix of all these components has made the Mexico weekend a tougher one thus far for Purple Bull. Marko believes the trip top subject gained’t be as a lot of an element on Sunday, since drivers go slower by means of the quick corners throughout a race trim and the automotive runs barely increased. “After all, as a result of the automotive is increased, and it is extra heavy, so you will not contact the bottom.”
Purple Bull’s motorsport advisor nonetheless considers a podium potential – however Verstappen is much less optimistic: “The automotive simply is not working, and it will not work on Sunday both. Let’s simply depart it at that.”
Learn Additionally:
If that’s certainly the case, Verstappen is aware of it has penalties for his hopes of a fifth consecutive world title.
“You may have 4 races to go after this after which a whole lot of constructive issues have to occur,” he mentioned. “I mentioned it earlier than: every part must be good from our facet, and this weekend will not be like that. If we are able to make it occur [in the title fight], then that’s nice in fact. But when it does not work out in the long run, then it does not. I am not too fearful about it.”
