> <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'll put some spring in your step! Nice. I wonder what the motion range is, and whether there's other limitations that affect acceleration.<p>Bose (the sound people) were trying to get in on the game & 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://incompliancemag.com/bose-electromagnetic-car-suspension-system/" rel="nofollow">https://incompliancemag.com/bose-electromagnetic-car-suspens...</a> <a href="https://www.extremetech.com/cars/259042-bose-sells-off-revolutionary-electromagnetic-suspension" rel="nofollow">https://www.extremetech.com/cars/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's no shock this comes back. The main challenge seems like it'd be knowing what you want the car to do when you have active ride control.<p>The only demoes we'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'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'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/reaction speed (changes in acceleration).
