Expand AWD Availability

I was looking at the Ford Fusions as an attractive car for my daughter and need All Wheel Drive. Unfortunately All Wheel Drive is only available on the higher priced Titanium model which puts the car out of our price range. Why can't All Wheel Drive be offered in the lesser models??
I completely agree. I have an expiring lease and my current lease has awd and I love it. As I am weighing my options for my next vehicle the "affordable" models of them do not have awd or 4wd and working midnights sometimes traveling far I'm not sure about the fwd since my last one kept getting stuck.
