Three Formula 1 teams have remained at Circuit de Barcelona-Catalunya this week after Sunday’s Spanish Grand Prix to test Pirelli’s 18-inch tires set for 2022.
Alpine, Alfa Romeo and Red Bull took part in the test hosted by the F1’s exclusive tire supplier on Tuesday and continue on Wednesday.
Alfa Romeo and Red Bull teams will be on track for both days, while the Alpine team was only around on Tuesday.
This will be the fifth test on 18-inch tires this year, the fourth on slick tires.
The tire manufacturer’s head of motorsport and car racing Mario Isola described how their development is progressing.
“The important elements that emerged from the test in Imola with the Mercedes was that all the constructions tested gave us a result that was coherent across different cars and across different circuits,” he said.
“So we had the possibility to validate different constructions starting from Jerez to Bahrain, Imola and we are now in a situation where I would say that the construction is almost finalized. In Barcelona, we start a test campaign on compounds.”
The teams are testing a “new family of compounds” which is designed to offer improved driving characteristics including less overheating and degradation. However, Isola noted, “we need to keep a bit of degradation because otherwise it’s useless to bring three different compounds.”
“But in terms of targets, I am confident that we are going in the right direction,” he added.
