To the folks on here parroting “Citroen did this 70 years ago” or “how’s this different from other adaptive suspensions,” what Porsche came up with is different and a completely active system that is able to proactively output forces toward each wheel, and fully control the pitch and roll behavior of the vehicle. This is similar in theory to the new Ferrari Purosangue, but is slightly different in execution (the specifics are mentioned in the article).
Other systems in the past are considered “semi-active” since they are only reactive to changes in the road surface or driver inputs. This includes magnetic-rheological dampers on GM cars (Corvettes, Blackwing), Porsche’s PDCC, or Mclaren/Rivian’s cross-linked hydraulic systems.
I will beg to differ a bit here though. If you ask me, I think all active suspensions have a reactive element to them. As for porsches new system, it still has to know when to apply force to each corner, and that requires data from other parameters like gyroscopes, steering angle, etc. So, it’s still reactive in the sense that it acts based on data from other parts of the car. The closest we can get to true proactive suspensions is with road scanning technology. And if you think about it, its still sort of reactive. Well, All in all, this along with other types of active suspensions, is pretty impressive.

How about Bose/Lexus’s system 30 years ago?

Never made it to production, but performs what you described.
