FERRARI FOLLOWS THE TREND AGAIN. SORT OF.
In Singapore, Ferrari has equipped its SF71H with a new serrated rear wing. The endplate was cut in two places, and the two flaps thus created were bent outwards so that the airflow is directed towards the sides.
The objective here is to reproduce the lateral expansion of the airflow that occurs at the level of the diffuser (i.e. the “outwash” effect). By increasing the expansion, it increases the pressure differential between the floor and the diffuser, and therefore the downforce (even if such a design probably generates a little more drag).
The model inaugurated this weekend on the Ferrari remains less complex than more sophisticated models found on the McLaren (Woking invented the concept in 2017), the Renault (since the Grand Prix of Canada) and the Mercedes (since Austria).
