Components 1 is at the moment going by a section of transformation that touches each space of the automobile, and to actually perceive it, it’s important to inform the story by the phrases of those that are experiencing this revolution from the within. It’s typically stated that mastering tyre utilization is key, since it’s the automobile’s solely contact with the asphalt, however within the seek for that excellent 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 essentially the most from the tyres, and on the future, analyzing what is going to change for 2027. Actually, we are able to already reveal that there might 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 instantly pertains to Pirelli: the provision settlement with Components 1 has been prolonged by one other season, by 2028. Receiving such a vote of confidence from the FIA and Components 1 should be significantly gratifying.
Dario Marrafuschi: “Appropriate. Our dedication to Components 1, apart from having began in 1950, that 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, we’ve got been a provider, a technical accomplice, and a worldwide accomplice for F1. Receiving this one-year extension definitely stands as a testomony to our ongoing dedication and the repute we’ve got constructed over these years.
“Components 1 is a extremely technical atmosphere dominated by expertise and innovation, but it surely goes past that. It is usually in regards to the belief we earn with all stakeholders and each entity we work together with, significantly Components 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 we’ve got achieved.”
Talking of the longer term, a brand new technical cycle has simply begun and is about to run till 2030. Would you want to stay in Components 1 till 2030, and even perhaps past?
DM: “We’re international companions and, above all, technical companions. Due to this fact, if the FIA and Components 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 the best way to define the longer term past 2028. Simply as we’ve got all the time finished previously, respecting the timing and requests of Components One Administration and the FIA, we will certainly achieve this within the close to future as effectively.”
Let’s transfer again to the current for a second, setting the longer term 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, doubtless 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?
DM: “The low-energy side is definitely a big technical issue, however so far as these two races are involved, I consider they have been distinctive and remoted instances. Because the begin of the season, the automobiles have undergone very vital growth by the groups. For these two particular races, we had made assumptions primarily based on simulations that had not but been up to date with information from the most recent aerodynamic packages delivered to the monitor by the groups.
“Due to this fact, 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 elementary position, as do the upgrades introduced by the groups, for which we’d not have acquired their newest up to date simulation but. It is a sequence of marginal features, perhaps a tenth of a second right here, a tenth there, and ultimately, you end up with greater 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 preferrred for the facility models’ cooling packages. Since these have been our design situations and the monitor was in glorious form, we discovered precisely the efficiency we anticipated. Minor discrepancies in sure races can occur, and they’re normally resulting from slight mismatches in information provide and the forecasts we make.”
Let’s return to the Monaco GP, as a result of this 12 months we noticed one thing completely different in comparison with the previous: an additional preparation lap. From Pirelli’s perspective, do you assume this comes all the way 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?
DM: “To place it merely, these automobiles generate much less vitality; they put much less temperature into the tyre resulting from a mix of things. To begin with, the general downforce stage is decrease in comparison with final 12 months, after which there’s energetic aerodynamics, as a result of on the straights, when the wing opens, downforce is lowered, and consequently, the tyres are usually 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 by electrical motor regeneration, switch much less warmth by the brake discs into the wheel rim, and subsequently into the tyre.
“So there’s a decrease thermal regime and the tyre’s thermal steadiness is completely different in comparison with final 12 months. This was one of many results thought of throughout the design section. The tyres are smaller than the 2025 ones, with completely different geometries and supplies in comparison with final 12 months. Nonetheless, Monaco, being a low-severity monitor, is a kind of circuits the place the tyre warm-up section takes a bit longer. Moreover, the C5 compound stage has been recalibrated, but it surely’s a C5 that must be usable on different tracks too, not simply in Monaco. Due to this fact, throughout the Monaco race weekend, the so-called preparation lap was adopted by just about all of the groups.”
Is the difficulty getting the tyre as much as temperature, or moderately retaining it inside that 3% window of grip?
DM: “It’s a matter of getting the tyre as much as temperature, and I’d additionally differentiate between the entrance and rear axles. As a rule, you must discover the best vitality enter and the correct process throughout the out-lap to heat up and convey each the entrance and rear axles into the proper window. That is one thing we’ve seen at a number of tracks. Usually talking, there’s extra work to be finished to get the fronts as much as temperature in comparison with the rears.”
Staying on a associated matter, wheel‑rim designs are open once more this 12 months, and groups are working to scale 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 on condition that the rules restrict how a lot scorching air could be launched from the brake ducts?
DM: “The open wheel rim rules are certainly a chance for the groups, maybe not very seen on tv for most people, however extremely vital. 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 otherwise. For one workforce, the aim is perhaps to warmth it up, whereas for an additional workforce, it is to chill it down, relying on the automobile’s steadiness. So, we see variations, and it’s a vital efficiency lever.
“They’ll successfully govern the strain build-up, from the beginning strain to the stabilised working strain, in an environment friendly method. Generally, once we have a look at efficiency and see a sure consistency in lap instances, particularly throughout a future, it is usually decided by how effectively the workforce manages to regulate the pressures, retaining them throughout the optimum window all through the stint thanks to those units.”
The groups are following two completely different paths. Some groups try to heat up the tyres by focusing on greater 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 retaining working pressures and temperatures down, or are there genuinely two completely different philosophies at play, with some intentionally in search of greater temperatures to make tyre heat‑up simpler?
DM: “Usually talking, working decrease pressures is a bonus for grip. Nonetheless, 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 loads of warmth into the tyres, whereas different groups would possibly face the precise reverse drawback. Not everyone seems to be doing the identical factor. That stated, the design of the brake ducts, the brake drums and the wheel rims gives an engineering lever to get the automobile to function the tyres of their optimum window.”
Let’s begin transferring in direction of 2027 whereas staying on this matter. Since this might set off a growth conflict, do you assume the FIA would possibly think about stepping in to limit wheel rim growth? Particularly contemplating that, as a reminder, managing the procedures when groups change rims already entails a big quantity of additional work for Pirelli as effectively.
DM: “I don’t need to touch upon choices that don’t fall beneath Pirelli’s duty. We will deal with the wheel‑rim developments that groups suggest; all the pieces is regulated. When wheel rims are modified, the FIA is clearly knowledgeable and, talking strictly inside Pirelli’s remit, we’re knowledgeable as effectively, for a quite simple cause. Slick tyres are fitted on the monitor, with new units mounted at each race. Moist tyres, alternatively, if they aren’t used, particularly throughout European rounds, are transported by Pirelli already mounted on the rim; they aren’t disassembled.

“We are going to quickly be heading to Spa. If a workforce desires to alter their wheel rim specification for Spa, this operation is carried out on-site by Pirelli by stripping the tyre, altering the rim, and likewise informing the FIA. It is because – and that is behind-the-scenes technical info – the FIA is conscious of a novel affiliation between the tyre, the rim, and the strain sensor mounted on the rim itself. It is a connection known as ‘pairing’, similar to while you pair Bluetooth earphones with a pc. The second a rim is modified, the FIA should be knowledgeable. Due to this fact, it’s a regulated course of that’s sustainable for Pirelli throughout the applicable guidelines dictated by the federation. Consequently, if wheel rim growth have been to be restricted, it definitely wouldn’t be Pirelli asking for it; it could be resulting from different causes that don’t fall beneath Pirelli’s duty.”
your information, have you ever observed that some groups have already reached the downforce ranges predicted for the top 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 just should be near the homologation deadline for subsequent 12 months’s building, or have you ever already labored upfront?
DM: “We’ve got already labored on these subjects, that are elementary to the design for the approaching 12 months. There may be loads of communication between Pirelli, the FIA, FOM and the groups. Any regulatory change proposed by the FIA is then accepted by the F1 Fee, that means these regulation modifications are subsequently accepted by the groups as effectively. The FIA’s aim is exactly to have a automobile package deal that’s sustainable for all events concerned, equivalent to aerodynamics, the facility unit, tyres, and the braking system, as a result of all the pieces within the automobile is carefully interconnected.
“A serious shift in aerodynamics would have an effect on all parameters, clearly together with the tyres, which is why we’re saved knowledgeable of regulatory selections. Coming to the purpose, this transfer by the FIA was a option to basically affirm the spirit of the present rules, retaining the automobiles inside a efficiency steadiness that was the goal for 2026/2027. Because it grew to become obvious that the groups had taken an exponential curve in aerodynamic growth, they’re making an attempt to maintain it throughout the automobile’s design window, so that every one the technical companions concerned can work understanding what the target might be.”
Concerning the compounds for 2027, do you count on the state of affairs to stay largely unchanged from what we’ve got in the present day or will one thing change?
DM: “Compounds are all the time being developed, and we’ve got already finished some baseline work on this in earlier assessments, a foundational stage concerning what the brand new materials packages for subsequent 12 months could possibly be when it comes to compounds. As soon as the construction is finalised, we are going to then optimise the compound scaling for subsequent 12 months primarily based on the outcomes already achieved. I can already reveal that there’ll nonetheless be 5 ranges; we can’t be including or eradicating a stage. We did take into consideration and focus on whether or not so as to add one other compound stage, however Monaco, ultimately, 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 shouldn’t be obligatory. We noticed an ideal race in Monaco as effectively, and if we have been to make use of a C6 in Monaco, it could be ineffective for the remainder of the season. Due to this, we are going to rescale the 5 compound ranges primarily based on subsequent 12 months’s goal performances. The targets are all the time to have a transparent efficiency differentiation between the 5 ranges when it comes to peak lap time, together with proportional degradation, so we are able to make selections that generate barely overlapping methods at each grand prix.
“This was the case in Barcelona, and likewise 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 are going to work, for instance, to make them a lot nearer to one another. This fashion, barring any security automobiles or neutralisations, there might be room for groups and drivers to decide on completely different methods, maybe managing tyre degradation in essentially the most optimum method for his or her particular automobile, and creating extra methods.”
Let’s return to a subject associated to the present tyres and the tyre behaviour. With the swap to 18‑inch tyres in 2022, the mixed section, when the motive force brakes and turns on the identical time, grew to become extra sophisticated due to the decrease sidewall. This 12 months, Andrea Stella defined that their information reveals variations in how the tyres behave in that section. What have you ever noticed, contemplating that the tyres are additionally narrower this season?
DM: “It is a physiological, or moderately 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 path, 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. This is the reason 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 offers you much less warning.
“Clearly, work has been finished to compensate for this impact, however as I stated, it’s a pretty physiological trait. This 12 months’s dimension change additionally influenced this impact barely, although not as dramatically because the swap from 13 to 18 inches. As for McLaren being extra delicate to it, I’d attribute that to the traits of their automobile. With out going into particulars, for positive followers have observed that McLaren has a really completely different automobile in comparison with the others; they selected a really completely different growth path. Due to this fact, it’s doable that their automobile is extra delicate to sure facets whereas capitalising on others, as a result of they made a definitive alternative to achieve particular benefits, but it surely comes with trade-offs, simply as different groups have had their very own benefits and trade-offs.”

Remaining on this matter, 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 effectively when trying on the information?
DM: “Let me provide you with an instance. To react exactly to that problem in studying the automobile on nook entry, some drivers are likely to saturate the entrance tyres coming 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 automobile to are likely to go straight. What does tending to go straight truly imply? It means it stabilises the rear extra, and the entrance features grip progressively. This driving model of oversaturating the entrance inevitably displays on tyre put on and temperatures as effectively. I can affirm that once we analyze the tyres for every workforce, at each race and each session, we measure the wear and tear and we do see variations.
“Clearly, these variations are then blended into different set-up selections as effectively, as a result of on the identical time, it’s not simply all the way down to driving model. Perhaps a workforce goes for a extra understeer-biased set-up, or adjusts camber angles, maybe decreasing the entrance camber angle to stabilise the rear, and in consequence, we see a distinction in tyre utilization by the wear and tear patterns. And that’s precisely the fantastic 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 automobile, that set-up and that driving model.”
Let’s swap to the subject of the ‘tremendous‑intermediate’, the tyre we mentioned initially of the 12 months as a doable possibility for 2027. We’re now in July: do you assume 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?
DM: “The super-intermediate is beneath growth; it’s one thing we’re actively pursuing. We’ve not deserted this path. We’re all the time very open to expertise and innovation, evaluating merchandise that supply an enchancment over the present ones, so that’s positively a route. I have to say that, sadly, we misplaced an preliminary wet-weather take a look at, particularly the one in Bahrain, which we weren’t capable of perform, and on the identical time, we do not have suggestions but on how these present automobiles behave within the moist with the prevailing product. Consequently, growth in moist situations is inevitably barely slowed down in comparison with our authentic plans. We are actually evaluating whether or not we are able to recuperate a minimum of someday 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 knowledge.
“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 ready to substantiate that proper now, because of the delays and the shortage of moist races we have had thus far. In any case, these wet-weather developments are clearly all the time shared with the FIA and Components 1 to make the most effective technologically obtainable alternative.”
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 complicated wouldn’t it be for Pirelli to organise all the pieces in time, particularly contemplating that this wouldn’t be a European occasion however one within the Center East?
DM: “That is fairly a puzzle, as a result of sadly, in relation to the Center East, it’s nonetheless not possible to foretell how secure the Strait of Hormuz space might be. There are two logistical bottlenecks we’ve got to cope with: the Strait of Hormuz itself, and the Houthi‑managed space off Yemen, which creates difficulties for cargo‑ship transit. We’ve mapped out just a few situations. If we needed to attain the Center East beneath the present situations, we would wish to circumnavigate Africa.
“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 alternate options as effectively: 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, we’ve got very dependable logistical companions, and the routes we use are precisely the identical ones utilized by the remainder of the F1 world. If there aren’t any tyres, there aren’t any automobiles both. Briefly, we’re a part of an enormous logistical ecosystem, and a grand prix isn’t added until the logistics have been totally assessed.
“Within the worst‑case situation, we’re 15 to 16 weeks; in the most effective‑case situation, about six weeks. Proper now, sadly, uncertainty is the dominant issue, and I couldn’t say how lengthy it could take to succeed in a possible race within the Center East, additionally as a result of, even assuming we might circumnavigate Africa, we’d nonetheless have to know whether or not the Strait of Hormuz is open.”
