&gt; <i>The motor-pump units are powered by the 400-volt battery used in Panamera E-Hybrid models and can put 2,248 pounds of force into each corner of the car</i><p>That&#x27;ll put some spring in your step! Nice. I wonder what the motion range is, and whether there&#x27;s other limitations that affect acceleration.<p>Bose (the sound people) were trying to get in on the game &amp; had a variety of test-bed cars, for a long while. But weight was huge, the computer processing sucked, and the linear motors were expensive as heck. <a href="https:&#x2F;&#x2F;incompliancemag.com&#x2F;bose-electromagnetic-car-suspension-system&#x2F;" rel="nofollow">https:&#x2F;&#x2F;incompliancemag.com&#x2F;bose-electromagnetic-car-suspens...</a> <a href="https:&#x2F;&#x2F;www.extremetech.com&#x2F;cars&#x2F;259042-bose-sells-off-revolutionary-electromagnetic-suspension" rel="nofollow">https:&#x2F;&#x2F;www.extremetech.com&#x2F;cars&#x2F;259042-bose-sells-off-revol...</a><p>Now that we have 400V systems in our vehicles, and now that we make utterly kick ass electric motors, and now that computers quake, it&#x27;s no shock this comes back. The main challenge seems like it&#x27;d be knowing what you want the car to do when you have active ride control.<p>The only demoes we&#x27;ve seen of Porsche Active Ride are ride stabilizing over bumps, which to be fair is probably the most useful thing for most people. But I&#x27;m very curious to see what happens when people start racing with active ride control, to see how cars can start taking performance advantage of these systems. This isn&#x27;t like what Bose did, with electromagnetic control: the electric motor runs an air pump that drives an air spring. That sounds very practical, but it returns me to wondering about factors like acceleration and jerk&#x2F;reaction speed (changes in acceleration).

Similar to Mercedes?<p>&quot;Mercedes-Benz S-Class stability system&quot; - <a href="https:&#x2F;&#x2F;phys.org&#x2F;news&#x2F;2013-09-mercedes-benz-s-class-stability-sensors-stereo.html" rel="nofollow">https:&#x2F;&#x2F;phys.org&#x2F;news&#x2F;2013-09-mercedes-benz-s-class-stabilit...</a>

lol 5200lbs curb weight<p>don’t care how good the suspension is, that thing ain’t getting around corners very well
