The Activa/Xantia suspension was nice, but it was nowhere near the Bose Magic Carpet.
It was a nice, mass market adaptive damping suspension.
The Bose is a fully active linear actuator, and fast. It can move your wheel around a speed bump independently. It's awesome. It was also north of $100k just for the suspension and iirc was never used in mass production.
No, the Citroen Activa active suspension was in production from 1996.
