Ferrari have an advantage in the use of the wind tunnel due to their place in the 2020 World Championship. However, the fact that they are allowed to use their wind tunnel more often doesn't provide that much of an advantage, according to
Mattia Binotto.
Ferrari finished sixth in the Constructors' Championship in 2020. An embarrassing result for the big team, but it did give it an advantage in 2021. A lower place in the final ranking gives an advantage in the use of the wind tunnel the following season.
