The X is the awd so I'm not sure what you're asking but i guess from a dig more traction and the grip at the limit is higher? but just go with A rwd S.

 

Edmunds.com and the infiniti sites can help, if you "build" your own and look at the descriptions for the different options that may help. Those helped me figure out exactly what I wanted. But we can give you more feedback if you have specific questions.

Prolly not much need for AWD down there, the traction and stability control will help get by in some of the slippy stuff even with just the RWD.

 

Virginia, get an S. I live in the Northeast and If my driveway wasn't behind my house on a long steep hill I would of bought an S and swapped over to snow tires. But I do love my Xs.
