The big feature 2 years ago was car starting to sprout LIDAR bumps but now that feature has become de rigueur enough that car brands need to figure out something new to stand out, hence the big push to advertise their active suspension.
Nio's new ET9 is showing off their car doing tricks like bouncing a soccer ball (https://www.youtube.com/watch?v=X3Ezjmz63U8), driving with a stack of glasses on it's hood (https://www.youtube.com/watch?v=WEr_sNp7XLM) and syncing the suspension to a movie (https://www.tiktok.com/@autogefuehl/video/745225999151335350...). Yangwang is showing it leap the car in the air. At the end of the day though, the more Hertz and more acceleration your active suspension system has, the smoother it can dampen movement inside the cabin and Chinese consumers are already getting very picky about how well specced the active suspension systems are.
In another 2 years time, Nio/Yuanyang style active suspension will have trickled out into enough midrange cars that it's no longer an exciting feature and Chinese car brands will figure out the latest new thing to compete. Meanwhile, American car brands will be barely half way through their model cycle refresh and just starting to think about incrementally adding a single feature or two and maybe adding a new curve to the body somewhere.
