Hi Hot_Georgia_2004:
___Although I believe in what you have written, there are some problems with the analysis with what I see on a daily basis …
___The 05 Civic EX w/ Auto Sedan can be found for the low 16’s in the Chicago area and with your 58 lmpg in the HCH, you can quite easily achieve 48 year round in a Civic EX. Near the end of my time behind the wheel of the Corolla LE w/ Auto, 46 - 50 mpg + was becoming the norm and the Honda Civic’s and Accord’s are easily a mile or ten better then the Corolla’s and Camry’s I have driven.
___Here is a list of automobiles and their FE with non-hybrid trained drivers behind the wheel …
Consumer Reports - Most fuel-efficient vehicles by category
Hwy in particular …
Echo (manual): Achieved 46 mpg w/ the EPA estimates as follows: 35/43 mpg
Civic HCH CVT: Achieved 45 mpg w/ the EPA estimates as follows: 48/47 mpg
Civic EX Auto: Achieved 41 mpg w/ the EPA estimates as follows: 31/38 mpg
Corolla LE Auto: Achieved 39 mpg w/ the EPA estimates as follows: 29/38 mpg
Accord EX I4 Auto: Achieved 38 mpg w/ the EPA estimates as follows: 24/34 mpg
Camry LE I4 Auto: Achieved 35 mpg w/ the EPA estimates as follows: 23/32 mpg
Accord EX V6 Auto: Achieved 34 mpg w/ the EPA estimates as follows: 21/30 mpg
Camry XLE V6 Auto: Achieved 29 mpg w/ the EPA estimates as follows: 21/29 mpg
___Your FE and savings in your HCH are a tremendous boon for the hybrid movement but our Hypermiler FE is not achievable by most in either a hybrid or non-hybrid alike unfortunately

In other words, some adjustments might be needed in your analysis is all.
___Good Luck to you and yours this Holiday season.
