Interesting how many mpg related posts come up in the winter. I know you live in Mexico, so I guess it is just by chance. In my book a S/C v6, has always got the mpg of a comparable N/A v8. Just look at the GXPs, basically the same mpg as a GTP. So I guess it would only surprise people who have never really compared them. More over, DIC mpg indications are notoriously inaccurate. Most all of them add a little mpg, because no manufacturer in their right mind would make them read conservatively. Think about it.
