To appear sporty
Is that an enthusiast thing? I initially thought it was a manufacturing defect.
It should be a pressure relief channel coming from the wheel arch: wheel rotation creates a complex air flow and I think this channel lets trapped air flow outwards (and stay attached to the vehicle sides, improving aerodynamics). Probably I got much wrong and more probably still, it’s of no real use for a road car driving under 200km/h.
Edit: could also be linked to brake cooling, now that I think of it…
Thanks for the answer. I am not really familiar with cars very much.
