Method 1 is at the moment going via a section of transformation that touches each space of the automotive, and to really perceive it, it’s important to inform the story via the phrases of those that are experiencing this revolution from the within. It’s usually stated that mastering tyre utilization is key, since it’s the automotive’s solely contact with the asphalt, however within the seek for that good alchemy, ingenious options proceed to emerge.
Motorsport mentioned all of this with Dario Marrafuschi, Pirelli’s head of motorsport, trying each at this time, significantly at how groups and drivers are adapting to this new technical cycle to extract probably the most from the tyres, and on the future, analyzing what’s going to change for 2027. The truth is, we will already reveal that there will likely be no C6 compound; as an alternative, the vary will nonetheless consist of 5 revised compounds geared toward widening race methods.

Motorsport: Let’s begin with a subject that straight pertains to Pirelli: the availability settlement with Method 1 has been prolonged by one other season, via 2028. Receiving such a vote of confidence from the FIA and Method 1 should be significantly gratifying.
“Appropriate. Our dedication to Method 1, other than having began in 1950, which means from the very first race in Silverstone with Nino Farina in an Alfa Romeo, has been a continuing presence over the past 15 years. Since 2011, now we have been a provider, a technical companion, and a worldwide companion for F1. Receiving this one-year extension definitely stands as a testomony to our ongoing dedication and the popularity now we have constructed over these years.
“Method 1 is a extremely technical atmosphere dominated by know-how and innovation, nevertheless it goes past that. It’s also in regards to the belief we earn with all stakeholders and each entity we work together with, significantly Method One Administration, the FIA, and all of the groups to whom we provide tyres and supply engineering consultancy companies throughout race weekends. All of this makes us extraordinarily happy with the work now we have achieved.”
Commercial
Talking of the long run, a brand new technical cycle has simply begun and is ready to run till 2030. Would you want to stay in Method 1 till 2030, and maybe even past?
“We’re world companions and, above all, technical companions. Subsequently, if the FIA and Method 1 have been to precise an curiosity in persevering with the connection with Pirelli, we will surely focus on it in the end. Proper now, it’s far too early to determine define the long run past 2028. Simply as now we have at all times executed up to now, respecting the timing and requests of Method One Administration and the FIA, we will certainly accomplish that within the close to future as nicely.”
Let’s transfer again to the current for a second, setting the long run apart. In Canada and Monaco, two circuits that put little or no vitality into the tyres, you noticed a pattern the place lap instances turned out faster than anticipated, seemingly as a result of monitor and asphalt situations exceeded the groups’ predictions. Is that this one thing you’ve observed elsewhere, or was it an remoted case? And if it occurs once more, how will you reply over the remainder of the season?
“The low-energy side is definitely a major technical issue, however so far as these two races are involved, I consider they have been distinctive and remoted circumstances. For the reason that begin of the season, the automobiles have undergone very important improvement by the groups. For these two particular races, we had made assumptions based mostly on simulations that had not but been up to date with knowledge from the newest aerodynamic packages dropped at the monitor by the groups.
Commercial
“Subsequently, it is a mixture of things. The asphalt and monitor situations make an enormous distinction. The temperatures we encounter throughout a race weekend play a basic function, as do the upgrades introduced by the groups, for which we’d not have obtained their newest up to date simulation but. It is a sequence of marginal positive aspects, perhaps a tenth of a second right here, a tenth there, and in the long run, you end up with larger efficiency than anticipated.

“We then noticed issues get again in line at Silverstone, exactly as a result of we encountered our design window situations, with monitor temperatures round 40 to 44 levels. The air temperature was round 25 to 26 levels, which I think about was additionally ideally suited for the facility models’ cooling packages. Since these have been our design situations and the monitor was in wonderful form, we discovered precisely the efficiency we anticipated. Minor discrepancies in sure races can occur, and they’re often attributable to slight mismatches in knowledge provide and the forecasts we make.”

Let’s return to the Monaco GP, as a result of this 12 months we noticed one thing totally different in comparison with the previous: an additional preparation lap. From Pirelli’s viewpoint, do you suppose this comes right down to the automobiles producing much less downforce than final 12 months’s fashions? Will it take extra time to convey the tyres as much as temperature on low‑vitality circuits?
“To place it merely, these automobiles generate much less vitality; they put much less temperature into the tyre attributable to a mix of things. To start with, the general downforce degree is decrease in comparison with final 12 months, after which there’s lively aerodynamics, as a result of on the straights, when the wing opens, downforce is lowered, and consequently, the tyres should not pushed down onto the monitor at excessive speeds as a lot as they have been final 12 months. Additionally, the vitality restoration elements, by exerting braking power via electrical motor regeneration, switch much less warmth via the brake discs into the wheel rim, and subsequently into the tyre.
“So there’s a decrease thermal regime and the tyre’s thermal stability is totally different in comparison with final 12 months. This was one of many results thought of through the design section. The tyres are smaller than the 2025 ones, with totally different geometries and supplies in comparison with final 12 months. Nevertheless, Monaco, being a low-severity monitor, is a type of circuits the place the tyre warm-up section takes a bit longer. Moreover, the C5 compound degree has been recalibrated, nevertheless it’s a C5 that must be usable on different tracks too, not simply in Monaco. Subsequently, through the Monaco race weekend, the so-called preparation lap was adopted by just about all of the groups.”

“It’s a matter of getting the tyre as much as temperature, and I might additionally differentiate between the entrance and rear axles. Most of the time, you need to discover the best vitality enter and the correct process through the out-lap to heat up and convey each the entrance and rear axles into the right window. That is one thing we’ve seen at a number of tracks. Typically talking, there’s extra work to be executed to get the fronts as much as temperature in comparison with the rears.”
Staying on a associated subject, wheel‑rim designs are open once more this 12 months, and groups are working to cut back working pressures. For security causes, you naturally present each the minimal beginning pressures and the working pressures as soon as the tyres stabilise. What have you ever noticed on this and the way are groups reaching these results provided that the laws restrict how a lot scorching air might be launched from the brake ducts?
“The open wheel rim laws are certainly a chance for the groups, maybe not very seen on tv for most people, however extremely important. The design of the wheel rim has modified loads in comparison with final 12 months; we’ve seen rims with hole spokes, which some groups name pockets, and that is exactly to facilitate warmth change with the cooling of the brake ducts, so to talk. We truly see variations among the many varied groups in who manages to, I would not say handle it higher, however handle it in another way. For one staff, the aim could be to warmth it up, whereas for one more staff, it is to chill it down, relying on the automotive’s stability. So, we see variations, and it’s a important efficiency lever.

“They’ll successfully govern the stress build-up, from the beginning stress to the stabilised working stress, in an environment friendly means. Generally, after we take a look at efficiency and see a sure consistency in lap instances, particularly throughout a future, it’s also decided by how nicely the staff manages to manage the pressures, protecting them inside the optimum window all through the stint thanks to those units.”
The groups are following two totally different paths. Some groups are attempting to heat up the tyres by focusing on larger temperatures, whereas others are aiming for decrease pressures and cooler working situations. Is it merely a matter of sure groups being extra environment friendly than others at protecting working pressures and temperatures down, or are there genuinely two totally different philosophies at play, with some intentionally looking for larger temperatures to make tyre heat‑up simpler?
“Typically talking, working decrease pressures is a bonus for grip. Nevertheless, relying on race tempo or automobile efficiency, some groups truly battle to maintain pressures low as a result of, by going very quick, they put a number of warmth into the tyres, whereas different groups may face the precise reverse downside. Not everyone seems to be doing the identical factor. That stated, the design of the brake ducts, the brake drums and the wheel rims supplies an engineering lever to get the automotive to function the tyres of their optimum window.”

Let’s begin shifting in direction of 2027 whereas staying on this subject. Since this might set off a improvement conflict, do you suppose the FIA may take into account stepping in to limit wheel rim improvement? Particularly contemplating that, as a reminder, managing the procedures when groups change rims already includes a major quantity of additional work for Pirelli as nicely.
“I don’t wish to touch upon selections that don’t fall beneath Pirelli’s duty. We will deal with the wheel‑rim developments that groups suggest; every little thing is regulated. When wheel rims are modified, the FIA is clearly knowledgeable and, talking strictly inside Pirelli’s remit, we’re knowledgeable as nicely, for a quite simple purpose. Slick tyres are fitted on the monitor, with new units mounted at each race. Moist tyres, however, if they aren’t used, particularly throughout European rounds, are transported by Pirelli already mounted on the rim; they aren’t disassembled.

the FIA is conscious of a singular affiliation between the tyre, the rim, and the stress sensor mounted on the rim itself. It is a connection known as ‘pairing’, similar to if you pair Bluetooth earphones with a pc. The second a rim is modified, the FIA should be knowledgeable. Subsequently, it’s a regulated course of that’s sustainable for Pirelli inside the applicable guidelines dictated by the federation. Consequently, if wheel rim improvement have been to be restricted, it definitely wouldn’t be Pirelli asking for it; it might be attributable to different causes that don’t fall beneath Pirelli’s duty.”

Taking a look at your knowledge, have you ever observed that some groups have already reached the downforce ranges predicted for the tip of 2026, and that the FIA is now discussing a discount in downforce for the 2027 automobiles? How might this discount have an effect on your work, particularly contemplating that you simply should be near the homologation deadline for subsequent 12 months’s building, or have you ever already labored upfront?
“We have now already labored on these matters, that are basic to the design for the approaching 12 months. There’s a number of communication between Pirelli, the FIA, FOM and the groups. Any regulatory change proposed by the FIA is then accepted by the F1 Fee, which means these regulation modifications are subsequently accepted by the groups as nicely. The FIA’s aim is exactly to have a automotive bundle that’s sustainable for all events concerned, equivalent to aerodynamics, the facility unit, tyres, and the braking system, as a result of every little thing within the automobile is carefully interconnected.
“A significant shift in aerodynamics would have an effect on all parameters, clearly together with the tyres, which is why we’re stored knowledgeable of regulatory selections. Coming to the purpose, this transfer by the FIA was a option to primarily verify the spirit of the present laws, protecting the automobiles inside a efficiency stability that was the goal for 2026/2027. Because it grew to become obvious that the groups had taken an exponential curve in aerodynamic improvement, they’re making an attempt to maintain it inside the automotive’s design window, so that every one the technical companions concerned can work realizing what the target will likely be.”

Relating to the compounds for 2027, do you count on the scenario to stay largely unchanged from what now we have right this moment or will one thing change?
“Compounds are at all times being developed, and now we have already executed some baseline work on this in earlier assessments, a foundational stage relating to what the brand new materials packages for subsequent 12 months might be when it comes to compounds. As soon as the construction is finalised, we’ll then optimise the compound scaling for subsequent 12 months based mostly on the outcomes already achieved. I can already reveal that there’ll nonetheless be 5 ranges; we can’t be including or eradicating a degree. We did take into consideration and focus on whether or not so as to add one other compound degree, however taking a look at Monaco, in the long run, we noticed that almost all automobiles began on the C4, which was the medium.
“Qualifying, even with an additional preparation lap, was thrilling with the C5 within the ultimate minutes of the session. That’s the reason we consider including a softer compound just isn’t obligatory. We noticed an ideal race in Monaco as nicely, and if we have been to make use of a C6 in Monaco, it might be ineffective for the remainder of the season. Due to this, we’ll rescale the 5 compound ranges based mostly on subsequent 12 months’s goal performances. The objectives are at all times to have a transparent efficiency differentiation between the 5 ranges when it comes to peak lap time, together with proportional degradation, so we will make selections that generate barely overlapping methods at each grand prix.
Commercial
“This was the case in Barcelona, and in addition in Austria, the place the two-stop technique was similar to the three-stop one. At Silverstone, the one-stop and two-stop methods have been far aside, however looking forward to subsequent 12 months, we’ll work, for instance, to make them a lot nearer to one another. This manner, barring any security automobiles or neutralisations, there will likely be room for groups and drivers to decide on totally different methods, maybe managing tyre degradation in probably the most optimum means for his or her particular automotive, and creating extra methods.”
Let’s return to a subject associated to the present tyres and the tyre behaviour. With the change to 18‑inch tyres in 2022, the mixed section, when the driving force brakes and turns on the similar time, grew to become extra sophisticated due to the decrease sidewall. This 12 months, Andrea Stella defined that their knowledge exhibits variations in how the tyres behave in that section. What have you ever noticed, contemplating that the tyres are additionally narrower this season?
“This can be a physiological, or quite bodily, matter for the tyre. The second you progress from 13 to 18 inches, the tyre sidewall top is lowered, and as a consequence of all this, the contact patch is shorter. When you think about the rolling of the tyre within the longitudinal course, the size of the contact patch is shorter, and with a shorter contact patch, the transition in driving really feel between having grip and shedding it’s extra sudden. Because of this we perceive the drivers’ feedback; it was anticipated that these difficulties would come up throughout nook entry in managing adhesion, precisely as a result of the snap provides you much less warning.
Commercial
“Clearly, work has been executed to compensate for this impact, however as I stated, it’s a pretty physiological trait. This 12 months’s measurement change additionally influenced this impact barely, although not as dramatically because the change from 13 to 18 inches. As for McLaren being extra delicate to it, I might attribute that to the traits of their automotive. With out going into particulars, for positive followers have observed that McLaren has a really totally different automotive in comparison with the others; they selected a really totally different improvement path. Subsequently, it’s potential that their automotive is extra delicate to sure elements whereas capitalising on others, as a result of they made a definitive selection to achieve particular benefits, nevertheless it comes with trade-offs, simply as different groups have had their very own benefits and trade-offs.”

Remaining on this subject, Stella was additionally referring to the drivers’ driving kinds and identified variations in how Antonelli and Russell use the steering wheel on nook entry. Have you ever observed these variations as nicely when trying on the knowledge?
“Let me provide you with an instance. To react exactly to that issue in studying the automotive on nook entry, some drivers are likely to saturate the entrance tyres getting into the flip. Saturating the entrance means they may enter the nook by giving a really sharp, fast steering enter, in order that the entrance finish experiences a step-input in direction of a excessive steering angle, which causes the automotive to are likely to go straight. What does tending to go straight truly imply? It means it stabilises the rear extra, and the entrance positive aspects grip progressively. This driving fashion of oversaturating the entrance inevitably displays on tyre put on and temperatures as nicely. I can verify that after we analyze the tyres for every staff, at each race and each session, we measure the wear and tear and we do see variations.
Commercial
“Clearly, these variations are then blended into different set-up selections as nicely, as a result of on the similar time, it’s not simply right down to driving fashion. Perhaps a staff goes for a extra understeer-biased set-up, or adjusts camber angles, maybe decreasing the entrance camber angle to stabilise the rear, and because of this, we see a distinction in tyre utilization via the wear and tear patterns. And that’s precisely the great thing about the competitors. That is exactly why we offer technical help to the groups throughout races; we provide our perspective on how the tyre itself is working for that particular automotive, that set-up and that driving fashion.”
Let’s change to the subject of the ‘tremendous‑intermediate’, the tyre we mentioned at first of the 12 months as a potential possibility for 2027. We’re now in July: do you suppose it might nonetheless be into account for subsequent season, particularly given how few alternatives you’ve needed to run in moist situations this 12 months?
“The super-intermediate is beneath improvement; it’s one thing we’re actively pursuing. We’ve not deserted this path. We’re at all times very open to know-how and innovation, evaluating merchandise that provide an enchancment over the present ones, so that’s undoubtedly a route. I need to say that, sadly, we misplaced an preliminary wet-weather take a look at, particularly the one in Bahrain, which we weren’t in a position to perform, and on the similar time, we do not have suggestions but on how these present automobiles behave within the moist with the prevailing product. Consequently, improvement in moist situations is inevitably barely slowed down in comparison with our unique plans. We at the moment are evaluating whether or not we will recuperate at the very least sooner or later of moist testing, maybe over the summer time, however clearly, not having run a moist occasion but means we’re lacking an vital piece of data.
Commercial
“So, we’re nonetheless engaged on the super-intermediate. As for freezing the event of the super-intermediate for 2027, I do not really feel able to substantiate that proper now, as a result of delays and the dearth of moist races we have had up to now. In any case, these wet-weather developments are clearly at all times shared with the FIA and Method 1 to make the perfect technologically accessible selection.”
Let’s end with a query associated to this season. There’s at the moment a proposal on the desk to make up for a cancelled race within the coming months. From a logistical standpoint, how advanced would it not be for Pirelli to organise every little thing in time, particularly contemplating that this wouldn’t be a European occasion however one within the Center East?
“That is fairly a puzzle, as a result of sadly, with regards to the Center East, it’s nonetheless inconceivable to foretell how steady the Strait of Hormuz space will likely be. There are two logistical bottlenecks now we have to take care of: the Strait of Hormuz itself, and the Houthi‑managed space off Yemen, which creates difficulties for cargo‑ship transit. We’ve mapped out a couple of situations. If we needed to attain the Center East beneath the present situations, we would want to circumnavigate Africa.
Commercial
“We’re speaking about roughly 4 months’ discover, it takes round 15 weeks of lead time to organise a transport of that scale. There are different options as nicely: we might undergo the Suez Canal after which cross Saudi Arabia from Jeddah in direction of the remainder of the Center East, offered that route is viable and environment friendly. Thankfully, now we have very dependable logistical companions, and the routes we use are precisely the identical ones utilized by the remainder of the F1 world. If there are not any tyres, there are not any automobiles both. In brief, we’re a part of an enormous logistical ecosystem, and a grand prix is rarely added until the logistics have been totally assessed.
“Within the worst‑case situation, we’re taking a look at 15 to 16 weeks; in the perfect‑case situation, about six weeks. Proper now, sadly, uncertainty is the dominant issue, and I couldn’t say how lengthy it might take to achieve a possible race within the Center East, additionally as a result of, even assuming we might circumnavigate Africa, we might nonetheless must know whether or not the Strait of Hormuz is open.”
