997CS4

After 3 years with lot of fun in a 997.2 C4 I am configuring a 2013 Cayenne S. I have two questions on the pano roof. Does any one know how much weight this adds compared to a regular roof? Does it make sense to order the Thermally and Noise Insulated Privacy Glass or will the “extra quietness” in the exterior be lost thru the noise the pano roof creates? Thanks!

also configuring a diesel S. have only read and heard the double-paned glass delivers the quiet, and cannot imagine the pano roof is going to create much noticeable noise. What I have noticed on other big luxury cars going above 90mph is a lot of blowing noise coming through the air vents in the dashboard, no matter how the fan is set and whether or not the vents are open. not saying the cayenne has this issue, but if it does, that would probably negate the extra quietness from the double paned glass...and might make any noise through the air vents even more noticeable and thus annoying.
what else is on your list? are you going for PTV+ and air suspension? what size wheels?

Thinking 20 inch, no 21 because of comfort and tire noise. Definitely airsuspension, but don't know about PTV+ yet. I feel it's probably a bigger plus in a 911 than Cayenne.

In my opinion and experience,PTV+ is just as useful in a Cayenne(had it on my 997tts)
I like having it on long sweeping highway turns as well as through twisties on smaller roads

What a combo! Diesel S + Air + PTV+ It would be a shame not to go for that combo.

I think PTV might be an even bigger plus in the Cayenne. It's much easier to get a 3200 lb sports car to rotate into a turn than it is a 4600 lb SUV. PTV helps in this regard and my experience is that the effect is noticeable in improved handling and steering response even in normal driving.

Also, since the PTV can lock the rear diff (automatically if needed, or via switch) can come in handy in winter driving or off-road ... more likely case on a Cayenne than 911!
