Anyone else tired of the vague & misleading claims from the Volt enthusiasts? Now that GM is pulling the same nonsense, the time has come for us to do something about it. Here's a summary of my attempt... What I did was create a spreadsheet which allows you plug-in (pun intended!) keys values of DISTANCE-TO-WORK and CHARGE-SUSTAINING-MPG along with individual entries to represent how you drive throughout the week. In others words, all the numbers are displayed for maximum clarity. After entry is finished (the purple cells), totals automatically calculate and the graphs generate. Here's a sample... And this the spreadsheet itself: 2007 format & 97-2003 format I also created downloadable documents: 2007 Word & PDF format The estimate results vary dramatically based on some rather critical values that will be far from consistent from owner to owner... as you can clearly see by playing with the spreadsheet. Anyone have detail of their own to contribute? .
