Observed fuel efficiency on the N20 / xDrive28i?
I'm not asking for the "stated" fuel efficiency. Just for what people are actually experiencing. My 2013 xDrive is averaging about 14 mpg in the city+highway (combined) during the 1st week I've had it. It's still on it's 1st tank of fuel (right from dealership) but it's substantially below the advertised 21/28.
Driving mode: Mixture of sports, normal and "eco pro" (?). I'd say I've spent most miles in the "eco pro" setting.
Driving style: Pretty normal. I've stepped on it during a couple of overtakes/passings but I've also been letting it coast for many more miles.
Environment temperatures: I'm in southern California, so it's 70-90 F for the most part.
Anyway, the fuel efficiency numbers don't seem normal. So, any suggestions?
