Fake car grilles and vents are becoming quite common on newer entry level cars. Why can’t they just, not be fake? Why can’t they just be actual grilles, whether they serve a cooling purpose or not? And just say throw the air out somewhere?

Fake car grilles and vents are becoming quite common on newer entry level cars. Why can’t they just, not be fake? Why can’t they just be actual grilles, whether they serve a cooling purpose or not? And just say throw the air out somewhere?

In: Engineering

The more air you move, the more energy it takes to move the car.

Grilles and vents move air. If that air isn’t doing anything useful then it’s a waste of air movement.

People buy cars off of asthetics first with efficiency being further down the line of what’s important (but efficiency is still important) so engineers cater to both by sticking on fake vents that only slightly reduce the efficiency but greatly “improve” the looks.

Real venting is difficult to design and implement because either it needs to be impossible for water to pool inside the ventwork, or the water that enters and pools has to be drained through limber holes, which are notorious for incubating rust from the inside out. It is trivial and extremely cheap to stick on a fake cosmetic vent though.
