Yeh I thought that was weird. It's not even on the lease/finance or DMV paperwork. Only place it said AWD was on the cars sticker price. I actually looked underneath to make sure there was a rear diff lol.Its not even marked on the car anwywhere. For all you know they might have built a FWD and delivered it to you.
I'm pretty sure the FWD versions have an axle back there too.
