Just traded in my 2009 Gen 2 for a new 2021 Gen 4 XLE. I used to be able to easily achieve pure glide in Gen 2, but can only do it for moments or not at all in Gen 4. Is that the way it supposed to work now? No complaints here - getting > 60 mpg on my first tank. Energy monitor just bounces back and forth from battery --> EM --> wheels mode to wheels --> EM --> battery. Once in a while I can get "no energy flow," but only briefly. It was very easy in my 2009 to get into this pure glide until car slowed down so much that I needed to pulse power. Is a) something wrong, b) I'm not doing it right, or c) that's the way the new system works?
