Yes, and the vehicles that show the absolute highest combined mpg's are all CVT's, not a single 5 speed competing on the right of the chart you so caringly linked to.
Call it an inconvenient truth.
And please, for the love of god, figure out what happens when you average numbers so we can all talk about the same thing -- helpful for discussing Fuelly, since the primary data they supply is AVERAGE COMBINED MPG.
However, should Fuelly find a way to supply CITY and HWY numbers, you would still lose the argument -- try looking at the 'pretty chart' again, even you can figure out which transmission provides the highest mpg's in that data set.
If you can't figure it out, here is a hint -- the green bars on the right of the chart? Those represent the vehicles reporting the highest combined mpg's, and green on that chart, it means CVT's!
See, a kindergartener could understand it, it is color coded, are you still confused?
