Well, once again, I need to actually verify this by hooking up some way of monitoring their function. The only "clue" I have so far is that I haven't seen them open since the fall in warmer temps.

In hot weather they are open at rest and I have to "assume" they are closing at speed, and in cold weather they are closed at rest and I have to "assume" they stay that way unless required to open for cooling... ??? I will definitely look into this further and post any findings.

One thing is for sure; if OEMs are integrating this system into cars it's pretty much guaranteed to be a VERY effective step in reducing drag.

That foam is starting to look pretty good. Finger clearance holes? That sounds like lost efficiency to me... can't you integrate some sort of shaved-door-handle solenoid or something overly elaborate to keep us lurkers entertained?
