I don't care anymore anyway, my car already has 1800 km. Smiley Drove from Munich to Frankfurt with my son, we really enjoyed ourselves, listened to music, did some bonding, a little road trip as he said. Was fun and 800 km were done. The last 200 km, before hitting 1500 km, I did at night on the Autobahn.

And this is where the BS creeps in, your Munich to Frankfurt trip would have been at constant (lowish) revs for the duration of the trip (unless you took back roads ?) which is precisely what the manufacturer prohibits.

These types of break-ins are nonsense in 2018 and pointless on a leased car Smiley

First at all, AMG does not prohibit low revs, AMG prohibits revs above 4500 rpm.

Second, German Autobahn...you cannot drive from Munich to Frankfurt at a constant 140 kph. The speed varied all the time. Break-in also requires using C (Comfort) automatic(!) mode only, so it is basically a low rev break-in because it is basically impossible in this mode to get higher revs, unless you start off from standstill. 

It has been confirmed by two AMG engineers, one of them in the AMG Owner's Lounge. There is something about that 4.0 Biturbo engine which seems to require a proper break-in. The "results" (most E63 S customer cars have much more than the factory claimed 612 hp) speak for themselves, so true or not, I will not do something else. Smiley
