C40 has solid upper grill vs P2 slotted upper grill but C40 has way bigger slotted lower grill. Unless we get active shutters, we need a grill for cooling of heat pump, etc.Yes but the C40 was cleaned up and looks smoother and more integrated.
Compared to competition the P2 while a beautiful design is inefficient and has poor aerodynamics. I sure hope they change the front grille to match the new C40. There is no reason to have a old fashioned slotted ICE grille on such a modern vehicle just to please traditionalists. If you look at the battery and drivetrain architecture the current grille does nothing for cooling. All new Polestars have a sleek front end without fake ICE grilles so naturally the P2 will follow suit.
Anyway, I don't see any data showing that the C40 is more aerodynamically efficient than P2.
