Even professionals say it is for cost cutting. From Car & Driver for example;
"It's a cost-saving move compared with the electrically powered screen in the A3 and the A6, but the execution is so precise and contemporary that no one’s going to miss the whiz-bang of watching the screen rise on startup."
If it didn't vent properly when retracted, they wouldn't have it retract.
How would it allow for better updating? Any updates being done would be software, not hardware.
Not sure what the thinness of the dash would have to do with it either when the screens are mere millimeters thick. In fact, in all cars where a fixed screen is used the dash is thicker to devoid them of looking like a tacked on afterthought with the screen. It goes UP behind the screen, not merely flat like a retractable unit at the top.
And how would it impact the HUD? Audi A8? Top notch HUD AND retractable screen of course. I don't see how those two things relate?
Sorry, but pretty much everything you say is straight out wrong. I have been working in this and adjacent fields for quite a while .... so it is kinda hard to surprise me but your arguments did
1. I don't know whom you are quoting but it's certainly not correct without further remarks. Of course, it is more expensive if you compare one screen fixed vs retractable. But this mostly is not the alternative. The choice is: bigger screen, better effects whatsoever or the elegant audiesque retraction. These alternatives do not differ in costs.
2. They vent properly (relative to their performance) but this requires lots of compromises and and adaptations to the screen and the dash. Just compare the rates of current iDrives and MMIs and you'll realize the limitations in performance pretty easily.
3. Not only software updates are being implemented during the cycle. Control units for instance are changed pretty often nowadays. If there are retraction mechanics located right beneath the screen, even smallest interventions are relevant.
4. It is rather trivial that the retraction (especially the complicated ones around multiple axes) require additional space. Audi just kept it since it was their USP. Also, this space is by definition limited to the upper dash where other modules (e.g. for wireless communication or sound systems should be located). Whether an OEM chooses to design its dashs more flat is another question. Mercedes up to now does not (but they made them less deep), BMW does...
5. Up to now, there is only one Audi on the streets that satisfies basic HUD needs and that is the new Q7. It is NOT top-notch, rather small, little range of adjustment. ALL Audis before incl the A8 have an additional box on the dash as the upper housing of the HUD. This is far from top-notch and a clear indication that the necessary building space for a multi-mirror HUD (~12 liters) was not included in construction.
