What goes on with the front air vents when driving?

[Fish Fingers]

So what happens with the front air vents when we are driving.....and what does it achieve?

I don't think I have seen this mentioned anywhere on here previously. ?

In the center of the car, what appears to be a grille opening is there to house the radar and camera. The tall openings below the headlights are there to create an “air curtain” around the wheel openings to guide air around and not into the wheel housings, which are filled with either 245 or 265-section tires (the rears are either 285s or 305s).

There are flaps covering the front of the two radiators. Normally they are open – both when driving and usually when parked as well.

However, when driving – if the cooling system decides it does not need outside air from flowing over the radiators – it will close the flaps (this is often called active air) – to improve aerodynamics.

Generally speaking its more efficient to have the flaps closed.

On a recent trip to Norway in a snow storm, the front hot completely covered In a thick,layer of compacted snow. The front camera, the front radar had 5 cm of snow on them and obviously did not work at all. With that design it all seemed to scoop up all the snow. And the rear also had a huge layer of snow on it, covering all the light bar and rear lights! I turned on the rear fog lights so there would be a red glow to show my white car. Our son in law did not see much of us in that ondition apart from two rec dots.

Since it was between minus 5 to minus 12 C outside, I had expected these from vents to be completely closed. My battery temperature struggled to get above 22 C, whilst it normally runs at 30 C? Is there a problem with my vents closing, since I have never seen them closed?

Cna anyone share a photo of the vents being closed? MY20 Turbo.
