The Citroen DS suspension was Hydropneumatic or possibly oléopneumatique - sorry, but these things matter (to me at least).

I know, but neither of those terms is in common usage. Maybe "air over hydraulic" would have been better.
Note that Citroen had the camber change issue sorted out back then.

OT One of my relatives had a DS back in the 70's. He ran a cattle station in the middle of nowhere, and the DS was driven on high lift for the 300 km of dirt, then lowered for the remaining 600 km of fast bitumen on his trips to Sydney.
