No matter what, in my normal route I usually show 24-25 mpg on all of my BMWs computers, even in ones I've had that have had a gas guzzler tax on
I was surprised by getting 26 in the G05 4.0 on the same routine 36 mile trip which is combined highway with 17 red lights (they're ALWAYS Red for me), stop and go, and last in town. I was so happy and surprised that I snapped a photo the other day to show my husband.
