Hi MGBGT:

___The wind tunnel effect as you mentioned is a traffic side draft.

___For that continual climb/descent route you described, about all I can add is I hope you would attempt a DWL technique through that area. Steady speeds are FE killers in the hills in my experience.

___Finally, to give everyone a heads up as to Krousdb’s accomplishments, he has taken his Prius II for a max tank range of 967 miles at almost 86 mpg. This is in a NA spec’ed Prius II with the smaller bladdered tank, not the non-PZEV Japanese version with the much larger cap. I hope most are cognizant of what it takes to achieve this level of FE in a Prius II as well as how important his comments are for those interested in taking their Prius’ or any HSD/eCVT based hybrid’s to their limits.

___Krousdb, Aurora, IL.? I drive by that city every day! If you are ever in the area, drop me a PM as I would love to meet up with another hybrid/FE enthusiast. Although I do not own an Insight anymore, the same basic techniques work in the Accord, Ranger, Corolla, and MDX. If you happen to be in or around the area on July 17, you will have to come with us to the Wi./Il. hybrid group meet to see the Milwaukee Brewer’s at Miller Park up north in Milwaukee. There are a more then a few hypermiler’s scheduled to appear again this year and Ericbecky puts on a pretty nice show for all that attend

___Good Luck
