RPO for gear ratio?

I am going to look at a couple of G6s tomorrow and was wondering how I tell which gear ratio will be installed. I do not want the one that will give me worse fuel mileage!

Thank you.

The final transaxle gear ratio is specific to each model trim level. They are not options. The 4 cylinder Ecotec will give you the best gas mileage even though its gear ratio is quite a bit shorter than the V6s.
