Hi. I bought my 1st 2008 Prius in Feb 2012. The first thing I really noticed was the "drag" (for lack of a better word) when coasting up to a light... no brake applied... no gas applied.... just... rolling. I noticed my 2008 would not roll as far as I was used to on a standard car. I assumed that was because of some sort of regeneration. Now... last week I bought another used Prius... a 2006. To my surprise, the 2006 seems to roll much further than the 2008!!! Almost like a regular car! So... what am I looking at here?
