Both of the junior categories have been used as a testbed for F1 in the past, such as with the increased size of the 18-inch Pirelli tyres, first used in F2 in 2020 before F1 adopted the same tyre size from 2022.
Just as Pirelli were able to develop the larger F1 tyre compound based on the findings generated in F2, the use of Aramco’s 100% Advanced Sustainable Fuels in F2 and F3 has been developed to be ‘drop-in’.
Drop-in fuels are developed to be chemically identical to conventional fuels, making them compatible with existing engine and power unit technologies. They remove the need for any major modifications to the cars to use them, and reduce CO2 emissions in the process.
