They certainly make it confusing if this is not what they mean....

In your sig you have...

Coming:
2024 GT3 RS
2024 Taycan Cross-Turismo Turbo S
2024 Cayenne Turbo S Hybrid

...and I'm curious how you have a 2024 Cayenne Turbo S Hybrid coming since there is no such 2024 model?

Needsdecaf

There will be. May end up being a '25. But they've said it'll be part of the lineup.

It makes perfect sense that a two chamber can be an improvement. One chamber for rebound and the other for compression. If electronically controlled then you can soften the ride without making it boaty. Softer compression but control rebound...there's only so much you can do with a three chamber air suspension. Couple that with PDCC that let's the sway bar work free when needed and you can soften low speed hits and still maintain the Sporty feeling. I might be wrong but that's how I envision the new suspension.

I am the first in line for whenever it comes. likely not 2024 model, though . I may take whatever lower step of hybrid is if it comes sooner (Cayenne S Hybrid?)

Yes, I have it and it seems to help with comfort but it's hard to say how much. I only directly compared to loaners that did not have it but they also were different in other ways, so hard to isolate. One reason I always add PDCC is that without it one of my kids gets motion sick when I drive fast in the mountains and with it she is fine. So for me, it's very much worth the money. Possibly higher comfort is a nice bonus too.

Still looking for diagrams of the 9Y0.2 2-chamber 2-valve air springs.

If anyone can contribute to links describing 955/7 and 958.1 air suspension it will help to understand the history.

...All The Crazy Engineering Details That Make The 2019 Porsche Cayenne Actually Fascinating (jalopnik.com)

Another cool bit of tech Porsche had on display was its three-chamber air suspension, which essentially blocks off certain cells inside the shock with the push of a button. By lowering the total system volume, the spring rate increases (which you might want for track driving), and by opening the valves and maximizing the total chamber volume, spring rates decrease for smooth highway cruising.

Having three chambers instead of one or two means drivers get a bit more granularity in tuning their suspension stiffness. Here’s a look at the new Cayenne’s range of spring rates compared to the single stiffness offered by the current generation Cayenne’s single chamber system (a two chamber system is also offered on the current model—that’s not shown for reasons unknown):

And here’s a nice breakdown of how the Panamera’s three-chamber air suspension system (similar to the one used on the new Cayenne) uses valves to vary the spring’s volume, and thus the spring pressure (which is proportional to spring rate):

The spring rates, Porsche says, can be adjusted manually via buttons on the center console, or they can adjust automatically if the car senses “strong pitching or rolling motion.” In addition to the adjustable spring rates, the air suspension offers the aerodynamic and off-road advantages of having six different ride height settings varying between 6.3 inches and 9.6 inches.

It would be great to get this level of technical explanation of the 9Y0 air suspension. This is the 970 Panamera system.

Having watched several reviews, even the "journalists" aren't consistent in their messaging. I've heard it called a bunch of different things.
