Formula One’s sole tyre producer Pirelli will introduce a new tyre allocation at this weekend’s Hungarian Grand Prix, mandating completely different slick compounds for every of the three Saturday’s qualifying session. F1Technical’s senior author Balázs Szabó reviews on the adjustments.
As Formula One approaches the ultimate leg of the season forward of the summer season shutdown, Pirelli will boost the proceedings by introducing a new tyre rule for qualifying.
At the twisty Hungaroring, drivers will probably be allotted with the three softest compounds: the C3 will probably be used as P Zero White laborious, C4 as P Zero Yellow medium and C5 as P Zero Red delicate. This will probably be a step softer allocation than final 12 months.
The selection is ready to spice issues up as Hungary typically options excessive ambient and observe temperatures which may lead to the overheating of the tyres. With warmth anticipated for Sunday, the aggressive tyre selection implies that the race might flip right into a problem for thermal administration of the tyres.
Commenting on the race weekend, Pirelli’s Motorsport Director Mario Isola mentioned: “The Hungarian Grand Prix has turn into a traditional occasion of the Formula 1 summer season season, and as such the air and asphalt temperatures, that are often very excessive, are the essential options.
“This places the drivers, vehicles and tyres to the check, not least as a result of the twisting nature of the observe doesn’t permit anybody or something to catch their breath. There’s a reasonably lengthy pit straight, which supplies the solely actual overtaking alternative beneath braking into the first right-hand nook.
“Then there are 13 more corners – seven right-handers and six left-handers – on a circuit that is second only to Monte Carlo in terms of slowest average speed; to the extent that the cars use similar downforce settings to Monaco. With so many slow corners, traction is one of the key factors for good performance and the biggest risk is tyre overheating.”
What does the new rule dictate?
Pirelli needed to debut a new tyre rule that’s referred to as Alternative Tyre Allocation at the Emilia Romagna Grand Prix. However, with the cancellation of the Imola race, the new tyre allocation will make its debut at this weekend’s Hungarian Grand Prix.
The Budapest race will host the debut of the Alternative Tyre Allocation with the new rule set to be trialled once more at the Italian Grand Prix throughout the first weekend in September.
Under the various tyre allocation guidelines, drivers may have to full every qualifying session with only one obligatory slick compound. Teams should use the laborious compound in Q1, medium in Q2 and delicate in Q3. If qualifying is moist, groups have a free selection of compounds as ordinary.
The new rule can even scale back the variety of tyre units obtainable for every automotive to 11, as an alternative of the 13 obtainable for a standard race weekend.
Each driver may have three units of laborious tyres, 4 units of medium tyres and 4 units of sentimental tyres. The variety of moist tyres stays the similar: three units of full wets and 4 units of intermediates, with an additional set of intermediates authorised if it rains on Friday or adversarial climate is predicted for Saturday.
On Friday, one set of tyres should be returned at the finish of every free observe session. An extra two units should be returned on Saturday after FP3. This leaves seven units of tyres for qualifying and the race, of which at least one set of laborious tyres and one set of medium tyres should be stored for the race.
Speaking about the new tyre rule, Isola added: “A new tyre allocation for qualifying (often called ATA, or ‘Alternative Tyre Allocation’) will probably be tried out for the first time, with the obligation to use simply the laborious in Q1, medium in Q2 and delicate in Q3 if situations keep dry.
“Both these changes, at least on paper, should lead to a wider range of options, particularly in terms of strategy. The ATA also saves two sets of dry tyres compared to the traditional format (using 11 sets instead of 13) and it will be run again at the Italian Grand Prix in Monza. After that, the FIA, F1 and the teams will decide whether or not to adopt it for next season,” the Italian concluded.
