Apparently deactivation happens when coasting or driving at a steady speed not under load. i would think this will work in normal mode as well. I was driving with a strong tailwind down the highway for over an hour at 60 mph and it showed I was getting close to 45 mpg !!! so I'm sure it was on !I’m fairly certain cylinder deactivation is only used in Eco mode. And yes, at 70 mph it will deactivate a cylinder, assuming you remain at a steady speed. This is usually most noticeable when using adaptive cruise.
