The 18-inch programme will step up a gear next season with 25 test days shared among the 10 teams, using either 2018 or 2019-based mule cars, before the definitive tyres are run in a three-day group test after the Abu Dhabi GP.
“We completed our planned programme as expected, covering 213 laps with the 18-inch tyres over two days,” said Pirelli F1 boss Mario Isola.
“This was very useful for us to take a first look at the new generation of tyres and start shaping the development path that we will follow for the remainder of this year and next year.
“Of course, it is hard to read too much into this test as these are still very early days, but we have accumulated all the preliminary data that we wanted in good weather conditions, so thank you very much to Renault and to Sergey for their availability.”
Some sources have indicated that Thursday’s meeting in Geneva saw an agreement to keep the 2019 construction fixed in 2020, as the September 1 deadline for confirming a new spec had been missed. However, others have suggested that the situation remains fluid.
