Whereas the character of two high-speed surprising failures within the Azerbaijan Grand Prix was already sufficient for Pirelli to unravel the troubles, it was Verstappen’s post-race feedback that added to the intrigue.
Along with his stricken Pink Bull nonetheless being returned to the storage, the Dutchman steered that Pirelli would shake off its duties for what occurred and declare that particles was the trigger.
“For positive [there will be talks with Pirelli] however we all know the outcome from that dialog already and that is a bit laborious to simply accept,” he advised Dutch TV.
“It is going to be associated to mess, it is like that. I am positive there might be talks, Pirelli is not proud of what occurred right here at the moment, nevertheless it would not change something to the race and the outcome I bought right here.”
Certain sufficient, when just a few hours later Pirelli’s initial diagnosis was that suspected debris was the cause of the failures to the Pink Bull and Lance Stroll’s Aston Martin, it drew a cynical response from Verstappen’s father Jos.
Tweeting in reply to a narrative on Autosport’s sister website Motorsport.com detailing Pirelli’s rationalization, Verstappen posted: “They all the time say that.”
Whether or not it’s truthful or to not recommend Pirelli is utilizing particles as an excuse for its failures, what is evident is that the highlight is on the Italian tyre producer like by no means earlier than to provide a full and correct rationalization about simply what went unsuitable.
The implications for the world championship of the tyre failure may have been enormous, and the dearth of warning each drivers needed to the issues has created some unease.

For Pirelli’s head of F1 and automobile racing Mario Isola, there isn’t a doubt that his firm should do what it could actually to ship solutions earlier than the French Grand Prix.
“The preliminary investigation is that it’s most likely as a result of an exterior issue, particles or no matter, kerb or no matter,” he stated.
“However I do not wish to soar to a conclusion now. The plan is to make an intensive investigation and are available again to a report back to the FIA and the groups that hopefully might be earlier than Paul Ricard. I’ve to say, I’ll push to have a report, and clearly it’s a precedence, earlier than Paul Ricard.”
Verstappen’s feedback about particles being singled out as a constant rationalization for tyre failure relies on his private expertise.
At Imola final yr, Verstappen was pitched out of the race with an analogous instantaneous tyre failure, which Pirelli later suspected was brought on by particles regardless that there was nothing apparent that the Dutchman had hit.
Just a few races earlier than, Lance Stroll had had a large crash at Mugello after struggling an surprising tyre failure, whereas on the British Grand Prix, the closing phases had been blighted by a variety of blowouts.
The run of incidents in 2020 prompted the push for stronger and heavier tyres that Pirelli launched for this yr, within the hope of guaranteeing there wouldn’t be repeat bother.
As Mercedes boss Toto Wolff stated final yr: “Lance Stroll’s accident in Mugello was actually scary, and there was Max’s DNF in Imola. Then we had been simply on the sting ending a race twice with Lewis.
“Due to this fact arising with a product that’s extra sturdy, and which means extra heavy, is the one resolution to that.”
However are the Baku failures proof that Pirelli’s tyres have not addressed the weaknesses proven final yr, or is particles the precise actuality?

Though the ultimate reply will solely come from the laboratories in Milan, who will use microscopes to analyse the stays of the failed tyres and people on different automobiles, Isola’s early prognosis of particles being the trigger relies on proof of what he noticed on Sunday evening.
First, there was the truth that each Verstappen and Stroll suffered close to an identical left rear tyre failures which got here completely out of the blue.
A 7cm reduce later discovered on the within shoulder of Lewis Hamilton’s left rear throughout the crimson flag break was certainly greater than a coincidence that there was a particles drawback.
There was additionally no proof that pointed to the failures having been the results of put on (from having been run too lengthy), nor the tyres overheating/being overstressed.
On the wear and tear entrance, neither Stroll nor Verstappen had run the tyres for particularly longer than anybody else. Stroll’s had failed after 29 laps, though they’d been run on a full gasoline load early on.
Verstappen had pitted for his hards on lap 12, which was one lap earlier than team-mate Sergio Perez and one lap after Hamilton, that means they’d run for 36 laps.
However different drivers had stopped a lot earlier: Lando Norris and Fernando Alonso on lap seven, and Charles Leclerc on lap 9. Not one of the tyres on these runners had proven any proof of issues.
Then, concerning being overstressed, if that was an element then it will be the suitable rear that may have been anticipated to fail first, as that is the tyre that’s put underneath probably the most stress across the anti-clockwise Baku circuit.
Pink Bull itself stated that there had been no indication from the information, nor criticism from Verstappen, that the tyres had been attending to the top of their life or being pushed too far.

Group boss Christian Horner stated: “They may have lasted straightforward. From the sturdiness that we may see, and for the way in which that Max driving the automobile, it ought to have been greater than snug.
“The tyre wasn’t being abused, the temperatures had been all good. The race engineer had principally solely simply checked in with him to ensure all the things was underneath management after which ‘growth.’ So it was completely surprising.”
An instantaneous failure does level in the direction of the concept of particles inflicting the issue , one thing that’s additional embellished by the reduce present in Hamilton’s tyre.
Isola added about Hamilton’s tyre: “It was clearly coming from particles. The tyre remains to be in a single piece and you’ll see that the reduce just isn’t following any path [of tyre rotation].”
Isola additionally thinks that if there had been a failure triggered by put on or overheating, then there would have been warning indicators. A failure triggered by particles would occur virtually instantly.
“It isn’t one thing that might occur a lot earlier, after which they had been operating and shedding air,” he defined. “In any other case you possibly can see from the telemetry that they’ve a puncture. You’d have a lack of strain, which they did not discover.”
Hitting particles on a monitor can be much more more likely to occur on a avenue circuit than regular extra open circuits. When items fall off automobiles on common circuits, components usually bounce off in to the grass run off space or gravel traps.
In Baku, particularly on the beginning/end straight, something that falls off a automobile might be bounced off the partitions and particles fencing and again on to the monitor, able to be hit by the following automobile by means of.
Again in 2018, when Valtteri Bottas misplaced a victory after selecting up a puncture when he hit particles on the straight, that piece was large enough to be noticed on tv.

Pirelli will now pore over video footage, onboard cameras, and any pictures, to see if something could be noticed as being a set off for the Stroll, Verstappen or Hamilton issues.
A rogue kerb or drain edge is also guilty. One idea is that Hamilton’s tyre was broken by particles from Verstappen’s crash, whereas Verstappen ran over a bit left over from Stroll’s accident. That will then go away Pirelli attempting to know what triggered Stroll’s difficulty.
Though telemetry information will provide few clues about when and if Verstappen and Stroll did run over particles, the forensic evaluation at Pirelli could possibly perceive issues from trying carefully at how the reduce has developed – particularly the Hamilton one. If the sides stay sharp and outlined, then it’s most likely a recent reduce, as an older slice may have had its edges extra roughed up.
What Pirelli wants now’s solutions, each for itself in guaranteeing its merchandise are as sturdy as doable, but additionally to reassure followers, F1, the FIA and drivers that what occurred in Baku was a freak occasion.
“We are going to do our greatest to try this as quickly as doable,” stated Isola.
Whether or not the solutions might be sufficient to finish Verstappen’s scepticism, although, might be one other matter.
