Hello to everyone and just wanted to share.
I've had my M340xi for almost 18 months( 13k miles) and took a family road trip from Virginia Beach to Indianapolis. I used the Euro Eco tire pressure values (40 psi front and 46 psi rear). Two adults, two kids, and a full trunk. We averaged 33 mpg on mostly interstate roads. For perspective, we went from sea level through the mountains to the midwest. Pretty impressive fuel economy.

What mode were you in? On highways when using Assist. Driving I put it in Eco Mode but I don't track mileage so not sure if it makes a difference.

I took a long trip and averaged about the same in my M340. Really impressive that with the switch of a mode this car can go from spirited driving to respectable MPG for the longer trips.

Very nice! 😂
Yep, If I drive like a douche, my fuel economy plummets. Usually after I fuel up in the area by my neighborhood, I usually run in sport plus and start off with really bad fuel economy. That's why this car is awesome. You can drive sensibly and a douche when ever. Best all-arounder! Cheers!
