And those Teslas? Those look like they were designed to have a grille opening there and it just got closed up as an afterthought. Really not a great look for the car, especially when there are some Teslas that are really sleek looking.
Being electric, I guess it would have been silly to put in even a fake grill like Chrysler did with Sebrings.......
Those Sebrings were bottom breathers, and didn't need the upper grille opening, so I suspect that Chrysler styled it to please a more conservative customer base that expected it to have a grille.
The Avenger (same Diamond Star platform) took a different direction, though, and eliminated the upper grille.
'97-'00 Sebrings had a partially open grille (the top half) that actually did feed to the radiator, though.
