It will be this month Pirelli also started a development program on the racetrack 18 inch tires for the season 2021. In two days (September 12 and 13) it will be Renault with a redesigned race car for larger bikes tested in Le Castellet, which is for colleagues from Motorsport-Total.com also confirmed Mario isola, sports boss Pirelli. "A few days after Monza, we will start with Renault in Le Castellet. In addition, it will also test Mercedes, most recently with a regular race car. This will also be the first real 18-inch tire test with a redesigned test car. So everything is new and there are a lot of questions. It is important for us to start this month. Then we have enough time to react if the behavior of the new tires does not match the predictions of our simulations."
It has not yet been officially said who will be on the track Paul ricard sitting in a race car Renault, all pointing to a test racer Sergei Sirotkin. In addition Renault the teams also expressed their readiness Mercedes Benz in McLarento redesign their last year's race cars for the needs of new tires. McLaren will test for the first time with a redesigned race car October, Mercedes Benz pa December - both teams also in Le Castellet.
In the first test with Renault will be in words Islands in the spotlight the construction of a new tire. “Because of this, we will take one mixture that we know. We cannot determine the construction in the first test. We will start with the known construction and then test different variants. It is important to us that the test cars are representative in terms of performance. The 2021 race cars will be completely different, but we can’t ask the teams to make a 2021 season car for us.”But in my opinion Islands there are no problems here. “In 2021, racing cars are supposed to have less vacuum, and removing or reducing the vacuum is always easier than increasing it."
It is during this season Pirelli for new tires planned 25 test days. These can be done by other teams and not only Renault, McLaren in Mercedes Benz, however, they have to convert this year 's chassis into a matching test car. The flight of this is after final races season c Abi Dabi there is also a three-day test on the schedule, where the use of such a test car is prescribed. “If they don't build a test car, they won't be able to take the test in Abu Dhabi,Isola explained. “The test in Abi Dhabi is also supposed to serve to enable us to choose tire mixtures for the first races of next year. So if a team doesn’t have a test car, they won’t be able to make that choice."
