STS getting V-6 AWD option

Much like the low-availability problems Ford is having with the all-wheel drive versions of the Chicago cars (Five Hundred, Freestar, Montego), Cadillac is experiencing the same with the STS. Currently the STS only offers AWD in the top of the line V-8 version attached to an expensive "Premium Luxury Performance" package but GM is ramping up the AWD as a $1900 stand-alone option for all models. GM has had a back-log of AWD orders for the new sedan.
