Darin,I was looking back at Blackfly and the Insight tail,compared to the Civic.They both had more of the elliptical cross-section like Morelli is discussing in his fluid tail article,especially Blackfly.
It kinda begs the question,would the Prius tail have a better shot at performance if those corners were softened?
I tried to give some images,but I can't get photobucket to work on this computer.I'm out in West Texas looking after a friends animals for 10-days and this machine doesn't seem to work for images.Sorry.
