In other words, the buildup and decay of steering effort during back-and-forth maneuvers is more consistent with HPS, an advantage useful during passing maneuvers. Higher efforts do not equate to better feedback, but at least the 535i’s on-center characteristics lend a more secure sensation on the highway. http://www.caranddriver.com/features...n-test-feature |
This is the reason I like Hydraulic steering. I have logged over a million miles on the highway in the livery business. I have also driven across country many times. Through Canada, and up to Alaska. I have spent many hours on the highway sometimes driving as much as 18 hours a day, or more.
I like the hydraulic steering because as I get jostled around on our poorly maintained roads in the U.S. the steering wheel doesn't move around with me. It stays put, and fatigues me less. It is more work, and feels less secure than EPS.
