Head of Chassis Enrico Cardile said that the aerodynamics on the SF21 underwent a "radical" revision with two goals in mind given the 2021 rules cut downforce around the car's floor and rear wheels.

[3] The entire front section of the car underwent refinements, with the new front-wing returning to a 2019-style emphasis on the outwash effect.

It also featured a new lateral drift, both for the shape of the bulkhead in the outermost edge, and in the foot curb area with a small flow diverter in front of the tyre.

[5] Addressing the power deficit of their 2020 contender, Mattia Binotto stated that "the [new] engine is running well on the dyno" and that its performance had progressed "significantly" compared to 2020.

"[8] Ferrari had a much-improved season relative to its disastrous 2020 campaign with the SF1000, with Leclerc achieving 2 pole positions in Monaco and Azerbaijan.
