The Italian brand began the test development of the tires of 2017 in July with the help of Ferrari, Red Bull and Mercedes. The three teams changed their cars of 2015 to increase the load, but according to Pirelli is insufficient to simulate that there will be next year.
Mario Isola, head of Pirelli Motorsport, has expressed concern about the test being made with a view to developing the tyres of 2017. After having made around 4,600 kilometres of testing in a circuit as varied as the Fiorano, Mugello, Montmelo, Paul Ricard, Pirelli has been determined that the single-seaters prepared by Ferrari, Red Bull and Mercedes they lack about 20% of downforce to simulate accurately the levels that will be obtained with the single-seaters 2017.
“we don’t have much time.”, and told Mario Isola in a statement to Motorsport. “Are working to generate higher load (aerodynamics), they know that they have to react quickly and we know that we are doing everything possible to achieve it. We are working with them to have cars that are truly representative of the conditions that there will be next year, so that all can test and we can provide a tire that next year is correlative to the information collected”.
From the start, the biggest concern on the part of Pirelli was that, and now that the development of the tires is more advanced and the cars of 2017 are in a terminal phase of its design, Mario Isola set at 20% the minimum that teams must win for successive test. “it Is difficult to say. Depends on if you consider the beginning of 2017 or the end of the season. We’re going to see a development quite large, which means that we are further away from the goal, probably we are missing about 20% of downforce”, a figure that could grow quickly, since they are traditionally the first year of entry into force of a regulation, the progress is very significant.
If the cars are not able to generate more downforce, Pirelli will not be able to simulate the stress of real will have to put the tires, triggering performance problems or uneven, even, security. “The problem of not having the downforce at the optimum level is that it does not squeeze the compound in the way that is expected to go to make new cars, by which we are evaluating a degradation that probably is not the correct. When the performance and the aerodynamic load increases, you have more degradation, so that now we have some numbers, but we need cars with more load to have the information indicated”, concluded Mario Isola.
The teams have based the increase of downforce of their cars 2015 addition of flaps sealing on the side edges of the floor of the car to increase the downforce, in addition to the implementation of the beam wing (plane or flap at the base of the rear spoiler). Only Ferrari has widened the rear wing to get close to the rules 2017.
