LS 400 with the Bose Active Suspension
Have you guys ever heard of the Bose Active Suspension? This demo video of an LS 400 with the suspension is pretty incredible!

Wow, it's really funny to see that Cnet posted this video on the BOSE suspension today, as I was just watching the old clips yesterday.. Talk about an odd coincidence. 
Though this subject has been mentioned here many times, it's great to see new coverage on the subject. Thanks for sharing!
I wonder if that was recent footage of those two cars. I remember that the BOSE modified model had BOSE decals all over it, as well as a BOSE plate. Maybe the have both cars in a warehouse(?).

Yes, very cool. The video is over 10 years old, so it's not new. Interesting that Bose chose to use the LS as a development platform.
BTW, a friend of mine from my lab (robotics, control systems) back in the day went to work for Toyota in Japan for a couple of years starting in about 1990 after finishing his Ph.D. They worked on active suspension (perhaps as a research project for the LS?) and concluded that passive suspension or actively tuned passive suspension was a better consumer solution than an active solution (as Bose demo'ed there) shows.
So Lexus surely looked into something like this back in the day and decided not to do it.

tl;dr it was too heavy and too complex\expensive.
I'd imagine it used hydraulic systems, but OEM's are already creating this with active shocks today (i.e magride). It's much more subtle than this video, but it's the same general concept. Since the systems can update hundreds of times a second they can react to bumps and soften a damper or shock.
But still, adds complexity and cost.

And I expect the actuators were electromagnetic rather than hydraulic, for performance / bandwidth reasons. We'll see what actually gets implemented.
