Hi Dan:

___I googled the term a few years ago since I was using it for my own purposes here. Apparently it was coined first by someone over at C&D back in 2002 IIRC but there definition most certainly did not fit what I was using it for?

___You might consider not mixing derbies, optimized routes, competitions, or the various techniques (FAS, P&G, Rabbit timing, Ball - in - the - Bowl, etc.) to get you there in the definition. You do not need any of these to hypermile as it is a day to day activity and anyone can achieve it with a lighter foot then they may have used in the past. Extreme Hypermiling may include all of the above but even Valedictorian Hypermilers run their commutes using all the tricks day in and day out, not just in a derby or competition … Then again, hypermiling is a competition between ones self and his or her automobile, the elements, and others and their automobiles most of the time

Other cars such as the Honda Civic Hybrid have also done very well.

___The doing well part ... The HCH, Prius II, and Insight have all seen better then 115 mpg so adding the HCH as an afterthought would be a disservice to HCH owners everywhere imho Including a Geo Metro into the mix was a mistake as well. I doubt anyone has seen beyond 75 mpg over a tank in one of those whereas the 3 hybrid’s named above have seen beyond that. I think I remember one of our esteemed members nailing a 78 mpg tank in a CRX-HF or something similar 10 or 15 years ago? Finding out who and the actual maximum range/FE of the Geo Metro (the XFI I think was the high mileage one?) would make for a good research project though.

___Good Luck
