2009 4dr SUV 288-horsepower 3.6L V6
6-speed shiftable automatic FWD		 Too Early to judge (625 miles on her). Initially, 1st tank 15.6 mpg. I am attributing the low mpg due to the honeymoon of a new vehicle and sitting idling for extended times while figuring out how everything works (and showing features to others). see full Saturn Outlook review

6-speed shiftable automatic AWD		 Good balance between towing capacity and fuel economy. For a rather large vehicle I think 21-22 on hwy is pretty good, and 12-14 towing the boat. Most of my driving is highway commute, but it seems as though shorts trips around town the mpg is lower. see full Saturn Outlook review
