alt Hacker NewsMercedes does this with hydraulic rams, it's called Active Body Control (or Magic Body Control for the version that scans the road in front too).
That system uses hydraulic rams in series with the usual suspension springs and dampers, and can handle up to 5 Hz (i.e. it controls the lower frequency part of the spectrum so softer springs etc can be used, improving both ride and handling)

The Mercedes version is hydropneumatic suspension. It was pioneered in the 1940s and 50s by Citroen. Citroen still use on high end vehicles too. Byd has adopted more recently
It has always occurred to me that the car industry doesntprioritisee a smooth ride or this would be much more widely used.
I have a "road" (just concrete slabs which never graduated into a proper road) where I would love to test that.
Watching the video I wonder how much of it is combining that plus a car that’s higher off the ground. Mercedes cars will be more performance minded so it’s lower to the ground. Maybe SUVs could have the greater suspension range so it can handle larger bumps but I wonder how much any Sedan could.
The most comfortable car I’ve ridden in suspension wise was a Mercedes SUV. So maybe they figured that out already.
As I’ve grown older I’ve come to realize that what truly makes high end luxury cars is the suspension and the sound deadening. The other stuff is important but doesn’t really set the cars apart. Sitting in a little mobile room completely divorced from the sensory input of the outside world truly feels luxurious
