Reasearch break in - everyone has a belief. You have Porsche on one side, this guy in the middle, https://www.enginelabs.com/news/disp...mance-academy/, to this guy http://www.mototuneusa.com/break_in_secrets.htm.
Oh and here is one in the middle with some real interesting results.

Here are some facts
1 you are new to the car, don't go crazy and kill yourself
2 easy on the brakes for first few hundred miles
3 don't miss your 1,200 mile appt.
4 always make sure engine is at temp before getting on it.
Me? I personally think babying the engine is the worst thing you can do and that the recommendations in the manual are written with lots of help from the BMW legal team (see #1). Oh yea, in all my years on these boards I've never seen a person write "I was hard on my engine in the first 1,200 miles and I regret it" but that's just me  |

Get those rings bedded in properly to ensure good compression and minimal blow by in the long term. Cruising is no good for that. Rings need firm combustion pressure to force them into the bore to bed in before they glaze up.
I drive my m2c, on average, more gently now AFTER running in.
During run in I only took it out on "run in" drives. At least 45 minutes for full heat cycle, open roads, wide use of revs (5k is plenty), up to 2/3 throttle, drive it enthusiastically. Load the engine, brisk runs to 100mph.
Then get the oil changed (995 miles for me) and relax.
Now i use it normally, odd school run, traffic jams, town etc.

I too, do not "baby" the car and agree w/1-4. In fact, when babying the car early, I have seen higher oil consumption later in the car's life.
