What mpg does the car return on a highway cruise with a depleted battery? That is more a gauge of whether there is something wrong, than in urban driving, which is so personal to you and your driving conditions.
No, I am not replicating the conditions of the rating... I wouldn't know the conditions of how BMW conducted their testing. This is a simple instrument cluster reading so its nothing scientific. I do a reset after the battery reads "---" and I travel for 15 miles with 75% of it going 50+mph before reaching home.
