Sdrive with only 500 miles on it but I recalculated the mileage at 3 different times after putting gas in. First 200 miles 20, second 150 miles 23.5 and last 150 28.5 all mostly city. Used Eco Pro a lot. Just a comparison is the 2010 Mini Clubman S got 26.5 to 28 on the same driving, the Mini was manual. Too early to know for sure but it won't be far off the Clubman. Have not done any highway driving yet.
