OK, I misread the spec for the TRD Sport, its 2WD and part time 4WD that makes more sense. Limited and above get the fulltime 4WD. The sticker of our TRD Sport V6 with a 5 speed is 16 city and 19 highway. We get 19 locally where it's very hilly and 24+ on the highway.
Sorry, but I don't see...
Personally, I'm disappointed with the expected MPG compared to my 4Runner V6 and "old fashioned" simple transmission. Why 4WD rather than AWD, for non-off road versions, it adds complexity to the diff and probably weight.
