My 2007 GT 5-speed gets about 16-17 city and 24.75 highway when I drive right (cruise set around 78), 14/21 when I don't.
My 2006 GT automatic got 14-15 city and 21 highway when driven right, 12.5/18 when I didn't.
2006 GT was computer and hand verified; the 2007 is all hand. I went with a deluxe GT to avoid the door panel mess falling again, but the computer and hand were both very close.
I may be wrong, but I believe the 2011-2014 5.0s are extremely close, if not a slight bit higher than the 4.6 3vs.
