Automobile suspensions have come a long way from their humble spring and tension beginnings to the common hydraulic systems in place today, but researchers at Eindhoven University think they can do even better: electromagnetic suspension. Building on an idea that’s been incubating in the auto tech world for a while now, a team there now has a test car ready to demonstrate the technology, which they claim improves ride quality by 60 percent.
