The Tesla blog of 23 April includes "Fully Adaptive Suspension"
I have not been able to find much detail beyond what is written there.
This adaptive suspension is potentially a game changer. My 2018 P100D air suspension is good on the highway but my passengers complain that it is too rough on typical city streets (19-inch wheels).
Having an "ultra-cushioned feel when cruising on the highway or using Autopilot, and responsive, exhilarating confidence during dynamic driving."
will be a significant improvement and hopefully compete well with the adaptive suspensions of other manufacturers.
