McLaren is rivalling Red Bull in how many new parts are being produced as each team continues to heavily develop their cars despite the looming challenge of the all-new 2022 aero regulations. McLaren arrived in Hungary with a heavily revised barge board arrangement for its MCL35M. To understand the probable reasons for an apparently innocuous change requires some backstory.
This is a highly distinctive car within the constraints of the quite prescriptive technical regulations, with several unique solutions. The two hard points of distinction have been the diffuser and rear wing.
The McLaren’s wing has a small main plane and big flap compared to other cars (which will give it a powerful DRS effect but less than optimum performance in non-DRS running).
