In addition, some drivers sampled Pirelli’s new prototype tyres, with two additional sets each per car allocated for Friday only. These soft compound tyres contain elements that help to resist multiple impacts, as part of Pirelli’s ongoing development programme. The data from these tyres will now be analysed, with a view to using them in future. The same test will be carried out on Friday, next week in Monza.
With Spa being the longest lap of the year by some margin, the supersoft contained a notable performance advantage: now in excess of 1.2 seconds. This means that the softest tyre available looks set to be the default choice for qualifying, making it very important for the teams to gather as much wear data as possible today in preparation for the grand prix. If the hot weather continues throughout the weekend, the information collected today should have a direct correlation to qualifying tomorrow and the race on Sunday.
Paul Hembery, Pirelli motorsport director: “The teams were all able to accumulate a lot of relevant information that will be valuable when it comes to formulating their strategies for the race, with the supersoft being used at Spa for the first time this year. If the hot weather continues, as we saw some quite high degradation today, tyre management will be very important on Sunday. For today only, some drivers also made use of our prototype tyres, which were soft compound tyres containing certain new elements that are designed to further improve resistance to multiple impacts. This is part of our ongoing development plan, and we will now look at the data obtained to evaluate if these elements will be used in future.”
