For the Hungarian Grand Prix the teams will use softer compounds than last year. The C3 will be used as P Zero White hard, C4 as P Zero Yellow medium and C5 as P Zero Red soft.
Budapest will host the debut of the Alternative Tyre Allocation (ATA), with just one mandatory slick compound for each qualifying session. Teams must use the hard compound in Q1, medium in Q2 and soft in Q3. If qualifying is wet, teams have a free choice of compounds as usual.
Under the ATA rules, the number of tyre sets available for each car is reduced to 11, instead of the 13 available for a normal race weekend. Each driver will have three sets of hard tyres, four sets of medium tyres and four sets of soft tyres. The number of wet tyres remains the same: three sets of full wets and four sets of intermediates, with an extra set of intermediates authorised if it rains on Friday or adverse weather is predicted for Saturday.
On Friday, one set of tyres must be returned at the end of each free practice session. A further two sets must be returned on Saturday after FP3. This leaves seven sets of tyres for qualifying and the race, of which at least one set of hard tyres and one set of medium tyres must be kept for the race.
After the Hungaroring, the ATA rules will be trialled again at the Italian Grand Prix during the first weekend in September.
Hungary often features high ambient and track temperatures. With the race taking place at the end of July, and the circuit located in a natural bowl with little airflow, Budapest will be a challenge for thermal management of the tyres as well as driver fatigue.
The most common strategy at the Hungaroring is a two-stopper, with a one-stopper occasionally preferred. The choices made in 2022 were heavily influenced by a Virtual Safety Car and a Safety Car. Almost all the drivers made three stops, using all the available compounds. At the start, half the grid started on the softs and the other half on mediums, with the hards being used for the second or third stint.
Mario Isola: "The Hungarian Grand Prix has become a classic event of the Formula 1 summer season, and as such the air and asphalt temperatures, which are usually very high, are the main features. This puts the drivers, cars and tyres to the test, not least because the twisting nature of the track does not allow anyone or anything to catch their breath. There's a fairly long pit straight, which provides the only real overtaking opportunity under braking into the first right-hand corner. 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. Despite being a permanent track, the Hungaroring is not used very often and the asphalt conditions improve considerably during the weekend as the ideal racing line rubbers in.
"Usually, this race is all about strategy and tyre degradation. This year we have opted for a trio of softer compounds (C3, C4 and C5) compared to 2022, while a new tyre allocation for qualifying (known as ATA, or ‘Alternative Tyre Allocation') will be tried out for the first time, with the obligation to use just the hard in Q1, medium in Q2 and soft in Q3 if conditions stay 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."
