Seems I remember seeing a commercial about that back in the day.

The transition to full hydrolics was slow. In my research I guess the first of it was in the early 60’s Fiats with the dampers. They were crude and did an adequate job of providing a level, if not rough, ride at speeds. But most of the technology for what we have now was spurred by racing rather than street.

Been thinking - I think the Citroen had air suspension with pump(s) to level it out/adjust, and not the hydraulics I was thinking about...

The first one from Citroen (1954) was called hydropneumatic suspension as it used pump-driven hydraulic fluid and small nitrogen-filled bladders at each wheel to absorb road impacts while also offering load-leveling and, eventually, mitigating body roll. The main drawback to the early systems is that the hydraulic fluid could absorb water—and thus rot the system from the inside out. Citroen is now developing a new suspension system called the advanced comfort program. I can’t explain it, but here’s a site from road and track that may help:

Yeah, but if they’d fix the roads, it wouldn’t be such an issue.

True - the reason I got rid of my AMG version CLA 250 was because I busted 2 tires on a trip...

You probably had/have the 4matic system in it to try to assist in the ride with the 250. Any time I spend over $32K starting for a car, even a high horsepower model, for nothing but the chasis and engine mentioned so far, it better include a decent ride somewhere along the discussion. That leaks into a powerful amount of money to be a pinball when you add the warm fuzzies.
