when you reached that deadband state its pretty much gliding in "neutral" isn't it? If you press a little more wouldn't the electric motor kick in and slow down the rate that you lose speed (kind of gliding in a hch II). Sounds like both cars have simliar P&G techniques although battery assist is needed for the HCHII gliding as opposed to the prius deadband state which uses no energy at all. Does that make the prius the ultimate hypermiler car because when I check HCH photos I see some insane photo mileage postings espically above the 70 mpg range. I understand Prius owners can still retain that high mileage even if they hit quite a few stop signs or red lights but can HCHII owners do it too? Lately HCHII new EV glide mode have been useful during 30-40 mph ranges and was wondering if they were effective for 10-20 mph speed range too. What is the minimum speed till then EV glide mode will work?

i got around 20 km a liter when i drove a civic 5 spd using advanced hypermiler techniques
and now I drive a salvage nwh20 prius that gets almost to 25 km/l with 195,000 km to date.
