All to its objective to level the differences between teams, F1 has for two years implemented a system of restriction of the development time in blower and CFD, based on the classification of manufacturers of year N-1 (up toas of June 30) then of the current season (after June 30).

Clearly, the team that finished first in the ranking will have less time passing through a blower than the 2nd, etc..Until the end of the table.The goal is therefore to bring the differences together.

This means that Red Bull started the 2021 season with the 2nd total development time;But since the Milton Keynes team was first in the manufacturers' ranking on June 30, it was Mercedes who recovered a little time available compared to its competitor.

Conversely, Ferrari, 6th in the ranking of 2020 manufacturers, was able to have a good development margin in addition to Red Bull or Mercedes (more than 168 runs in wind tunnel in addition to Mercedes).Useful for developing your car 2022…

The aerodynamic development time is not everything: for example McLaren, with its obsolete blower, maximizes less passing time.

But the 2022 season will see an important change: the difference in the blower time between each place in the manufacturers' classification, will go from 2.5 to 5 %.A doubling supposed to level the tray even more.And it will be important at the start of aerodynamic regulations.

Mattia Binotto, who believed that the differences in blower time did not "change the situation" last year, would he say the same thing with this doubling of the gaps?

This means that Mercedes, remaining champion in the manufacturers' classification, will have 70 % of the total of the 7th of the 2021 season (Aston Martin).Red Bull will have 75 % of Aston Martin F1 total and therefore 5 % more development time than Mercedes.

Ferrari will have 5 % more blower development time than Red Bull, etc..

With 20 % time to blow in the wind tunnel in addition to Mercedes, Alpine will also have resources to execute her "plan".

At the bottom of the painting, Haas will have 144 wind tunnels in addition to Mercedes, and 900 "items" (simulation launches) of CFD that Mercedes.Or 45 % time to blow in blower in addition to Mercedes.The choice to sacrifice the 2021 season also finds its usefulness here.
