2012 model series 5. averaging 39.4 mpg since new. (great feature to be able to track mileage for entire life of car!). High is over 45 and low in mid 30's. Live in a hilly area and that affects MPG. On trips of 100+ miles generally 42-44 MPG. Based on what I have read most of us are doing better than the Ford C-Max which touts 47 MPG and is supposedly getting in mid 30's. Will be posting some dislikes concerning tail gate open/close and poorly designed sun visors.
