The problem with his statement is that we are running E-10, the difference in energy between E-10 and E-0 is only about 3.5%. So if your getting 50mpg, you should loose only 1.75mpg. Some cars like one of mine lost more because they don't seem to like E-10 for some reason or another.
One thing to keep in mind is if you are running E-100 you would have an octain of 122, in which you could run a much higher compression and possibly more than offset the lower energy per gallon.

Formula 1 car, yes please. MPG be damned. Actually, an efficient car could probably be made using pure ethanol for the very reasons you mentioned. It would be interesting to see how far that technology could go, although I don't think it can make up for the 1/3 energy density hit.
