He will drive miles with Mercedes Esteban Ocon, a Renault racer from next year, and a lesser-known Briton with Red Bull Jake Dennis, currently appearing in a series of touring cars, Red Bullu however helps with development in the simulator.
Special testing will take place at the request of Pirelli, as the track in Barcelona, due to the rough asphalt and long turns, makes it possible to test harder tires than the track in Le Castellet, where they were tested with Mercedes last month. Some teams opposed the testing, but the FIA nevertheless decided to make them possible.

Pirelli's boss Mario Isola explains what the purpose of these tests is: “The goal is to come to conclusions on the development for the 2020 season. We wanted additional testing to test a new tire compound that allows for a wider working range. These are harder tires. These tires could not be tested on the Paul Ricard track and fortunately we will have three racers available in Barcelona. This will be a very good opportunity to conclude development of our tires for 2020. "

Especially for Vettl and a few mechanics, next week will be very tiring, as they will fly immediately after testing on Tuesday. to Japan, where the seventeenth race of this season awaits them at the end of the week. After this year's bad season, the German is already looking into the next one, and any information gathered about the new Pirelli tires may come in handy.
