Here's my contribution.
Helpful to those curious about what mpg an X5M could provide.
This was my entire trip from Brooklyn to Cape Cod (7 days) including highway, traffic and local driving. I also had a family of 4 with a trunk full of stuff.
This was driven purely in Sport+ mode and what I consider to be "normal driving"
Not bad considering how much power it makes (over 600hp). I did the same trip last year and I got about the same. If i really tried to milk it and drove like a grandma the entire time I might be able to get another 1-2mpg but it wasn't worth it for me. I like to stretch its legs from time to time lol
