I have a 2014 328i F31 with CAI, an axle back 335 M-Performance Exhaust running Bootmod3 Stage 1 and roof racks with bike racks. I drive Sports+ pretty much 100% of the time with manual shifting. My fuel economy is about 13.5L/100km. Pretty much all town driving (very little highway driving).
When i was behaving (and car was stock), i could average around 9L/100km with a mixture of town and highway. Individual trips could be below 6 if I drive conservatively.
