Was getting about 46km before it got colder, and about 43km now, if I turn on heat will probably drop another 2km I'd say but I always preheat in the morning and is not needed.
Yeah it's the assistant pro which is so handy in m50 traffic, on the F30 it would switch off after being stopped in traffic for 5 seconds but now the car moves off on its own without hitting the pedal
