I agree. That's why I think it'll come in around 20mpg for the average use-case. Some will do better of course, and some will do worse.

I do think that for those long road trips where you blow through a whole tank (or multiple tanks) on the freeway, the car has the potential to do much better that the E9x M3 does today.
