All - not trying to start a "debate" here about how to break a car in. I think BMW has reasons for what they suggest - alas, I'm just not sure what they are

ddk632 - the guys at the PDC will tell you that they have to break the cars in per BMW's recommendations. I would be however curious what they say off the record. Of interest is that none of them are BMW employees
Actually the break-in rule is pretty easy as comparing to the M3 and there is no need for break-in oil change.
Up to 1200 miles/2000 km - drive at varying engine and driving speeds...not exceeding 5,500 rpm or 105mph/170 km/h
Also avoid transmission kick-down mode...this can be easily done.

From 1200 miles/2000 km to 3000 miles/5000 km.
Gradually increased up to a continuous vehicle speed of 135 mph/220 km/h.
And I did try sport mode a couple of time during this period before i had winter tire on.

I guess the M Twinpower turbo engine needs less babying than a natural inspired engine
