Is there a way for me to check to make sure the front flaps are working correctly on my car? Can I manually open and close them?

After you do a cold start with the car in normal mode, step outside the car and look at the front. They will be closed.

Note: If you opted for the Sport Design front fascia, you lose this dynamic aero feature.

Thanks I'll do that. Also I will update my Avatar now that I picked the car up. Cheers!

Excellent question, thanks for posting. I was wondering the same thing. Additionally, I found this info to be very interesting (yes, I am a nerd) about the air flaps from an early 992 press release:

"The Porsche 911 front continuously cooling flaps open and close depending on temperature, load and speed, appropriate to the relevant situation. The flaps are completely closed in the speed range between 43 and 93 mph if there are no parameters opposing this. This means that the 911 has the lowest air flow resistance, and fuel consumption is reduced. The flaps open from 93 mph and are fully open at speeds above 106 mph. This mode provides the best possible aerodynamic balance and optimum driving dynamics at high speeds. When the sliding roof is open, the flaps open from 75 mph. The flaps are always open if the driver switches on Sport or Sport Plus mode."

so they’d be always open for most drivers here

So I asked a question about the validity of these flaps and only detansinn bothered to reply. That said I've just had a thought.

The sports design front apron doesn't offer the opening and closing of the flaps. So can I take from this that Porsche think they are not worth a damn in reality if they don't have them on the sport design? After all the sport design apron doesn't define you or your driving style, for me it's aesthetics.

So I tired the cold start in normal today and they stayed open. I'll try it again tomorrow. Maybe I have to close my door after getting out? Do garage temps matter?

Or maybe Porsche do actually think if you option the SD front economy isn’t your highest priority?

In road test reports I haven’t read any that say the vents are closed with the vehicle at rest in any mode.

The implication from testers is they close in normal mode at specific parameters to achieve aerodynamic and fuel efficiency.

BTW I’ve never seen a pic of a stationary 992 with vents closed 🤣🤣🤣

Quote below

“They can now take any position between fully open and closed, moving in response to temperature, speed and load, with some positions dictated by whether the optional sunroof is open. Unless other parameters intervene, the flaps remain closed between 43 and 93 miles per hour, begin to open above 93 mph, and fully open above 105 mph or in Sport or Sport Plus driving modes.”

It's a sports car. Show me a single person who has purchased a 911 for it ecomony. Plus, how much economy do you actually achieve with it?

Not trying to be antagonistic or that guy, really just curious regarding the claims of the benefits of a flippy flappy front bumper.

I just wanted to make sure my flaps were working. That is all.

I did get 26.5 MPH on the way home from Florida. That's going 80mph too! Great MPG on this thing!

Well actually when I’m on a road trip range is important to me; unfortunately in my case made more so because as a MY20 owner I couldn’t option the extended range tank. These are sports cars but they are also daily drivers, one of the reasons they are so well regarded is their ability to do more than one thing well.

Porsche did this to meet government fuel economy and emission requirements…. only reason. If these two regulatory mandates did not exist, we would have cars with very different features. At least you can turn most of these features off with Sport or Sport Plus.
