My 5.4 gets a whopping 10ish in the city. My friends raptor get's better fuel economy (13 to 16) than my expedition and is about equal in weight but with worse rotational mass and similar gearing (32" tire with 3.73s vs 34.5" tire with 4.10s).
The 6.2 would equal or improve the expedition fuel economy barring no other changes or weight increases.
If you get 10 in the city youre doing it wrong. I have 3.31s and Im constantly loaded pretty good and I have to try hard to get bellow 14...
