I bought a G6 GT on the 9th of this month. I've been driving it around Phoenix. Obviously, the AC is on this time of year (it was 112F yesterday). I'm learning to drive with a lighter foot now (I only had 4 cylinders previously). Anyway, so far I've averaged about 25 mpg on the surface streets and 30.9 mpg on the highways inside and around Phoenix (101, 10, 17). That's actually better than my 4 cylinder 2002 grand am was getting. Again, I'm learning to drive with a lighter foot, too, so keep that in consideration. Maybe the Solstice will do better on mileage than reported.
