So, I don't know much about cars, but I generally expected for that part to be flush with the body. Is there any reason for there to be a grill like thing in front of the front door?
Can be for a few different reasons, but most likely is to aid in dissipating heat from the brakes and aerodynamics. Considering this is an EV, they are usually much heavier, and with more mass, means you need bigger brakes, and bigger brakes means more heat. There should be either a duct in the front grille, or under the car that scoops air behind the wheel well, which cools off the brakes at speeds, and this duct you see from the outside gets air out of the wheel well.
Another additional side effect can also be that scooping air out from under the car and to the outside means you have a low air pressure zone under the car, which helps create down force, which makes for better cornering speed and highspeed grip.
