Well, this post seemed to imply it:

technically speaking, the only real new tech with U7 is Disus-Z

S4 motor system is not just 4 wheel steering, but 4 separate electric motor. It doesn't look like the earlier efforts actually had separate motors for each wheel.

But U8 and U9 already has S4 motor system, so that's not new on U7

U7 also has R-EPS with 20 degree, which IIRC has also been achieved on cars before. But combo of S4 + 20 deg R-EPS might be a first.

Also, it's the first Yangwang model with carbon fiber brakes. Again, not new technology, but it's the combo of everything together.

Disus-Z seems like a rather revolutionary tech, first of its kind on a production vehicle. I wonder what the range of adjustments are on it. I'm expect that it can firm up if wanted to, but to what degree? Can it firm up and make the car sporty enough to feel lighter than it is? As I've mentioned before that's a tech that I've been waiting for for many years, can't wait to see it in action!

Nope, I have posted before, Disus-Z is similar to the Multimatic active suspension used in the Ford GT, Ferrari, etc. However, supposedly Disus-Z will also improve EV efficiency (that would be new).

Also, Rivian has a quad-motor vehicle on sale now.

That being said, it is true that U7 is probably the first EV with all of these things packaged together. However, it is still at an exotic price, so nothing new on that end.
