@tiejia_ev Matters a lot actually. As always with Tesla, to be sure of what you're getting, you really need to test the exact car you're buying. Or if it's a new one, hope that it matches whatever you test drove, assuming you liked the demo car.
The original Model S air suspension, as fitted on 2012-2013 cars (40, 60, 85, P85, but *not* counting the P85+ suspension option of 2013), is pretty soft. Good ride quality. Not the very smoothest out there but it's good. Handles just fine in *casual* driving. Not firm enough for really hard driving like a sports sedan. This is the air suspension my 2013 Model S P85 has. (Note, the base coil spring suspension rode and handled worse than the air suspension. Wholly inferior. I tested coil and air back-to-back when these cars were new.)
Then the P85+ with its "Plus" suspension option launched. This was significantly firmer and sportier than the regular air suspension. Felt like they upgraded bushings as well as dampers + springs. Way better handling, tighter feeling steering, etc. Still rode well, clearly firmer yet still good ride, really just very good suspension tuning overall. My favorite driving Model S that I've had as a loaner.
Then the dual motor cars launched. I remember the early 85D and P85D having decently firm suspension tuning and steering, reminiscent of the P85+. Not quite as nice driving as P85+ because of the extra motor weight up front, but still good, and you get AWD + more power. (Though the front motor whine was kinda loud on these early cars. They quieted it down a lot by the 100D.)
Additionally some early P85D reportedly had an *extra* firm suspension suspension option, even firmer than P85+. I'm not sure if I had this version as a loaner.
Then around the 90D / P90D era Tesla really softened up the air suspension again, staying quite soft through the 100D / P100D. I last had a P100D as a loaner a year ago. Very quiet, smooth, comfortable ride for highway cruising. Really excellent for that. However an absolute boat through the turns. Too soft, too squishy, and especially too heavy. Could really feel all that extra weight compared to my P85, despite both having similarly soft suspension.
Then came the Raven (approx 2019-2020) (where they dropped the kWh-based badging), which introduced adjustable/adaptive dampers to the Model S (standard on all Ravens I believe). I haven't driven a Raven. From what I've read they're at least as smooth as a (P)100D, and better controlled in turns too, though still very numb feeling (as most Model S are aside from P85+).
The newest Palladium Model S (approx 2021+ with the yoke, new interior, widebody, etc) has updated adjustable dampers (revised or at least retuned since the Raven). I haven't driven a Palladium either. I have ready VERY mixed things here on TMC, some saying they ride as well as any Model S when in comfort mode, and some saying they feel firm excessively firm all the time, too stiff over bumps, no matter the mode, as if the adaptive dampers aren't really adjusting properly. There might be real issues with the adaptive damping on a subset of the Palladium cars.
As a reference point, I have manually adjustable aftermarket dampers (coilovers) on my 2021 M3P, and the difference between soft & stiff settings is very obvious. You KNOW the adjustment is working, there's no missing it. So when some Palladium owners say they can't feel a difference between the comfort and sport modes with their fancy adaptive dampers, I feel like that can't be working properly, because the difference should be obvious.
Edit: Don't ask me where the oddball battery sizes like 70 and 75 fit into this. I've had them as loaners too but I don't remember when they were built or where they fit into this schedule of suspension changes. They are all pre-Raven of course.
