Never did i "break-in" my motor. Far as i look at it the bi-turbo v6 it isnt an AMG motor. It is mass produced (C400,C450,43). As Sean 1.8t said they do not need to be broken in. If it does say so in the manual, then oh well. From the moment i got her its been in S+ mode with M all the way up to redline and no issues. But whatever makes you sleep worry free at night is all that matters.

S+ and redlining from day one may not cause short term reliability issues, however it could lead to bad gas mileage as well as engine oil loss, and engine problems down the line.
I've seen people getting denied warranty work by Mercedes because of improper break-in and engine blowing up, so don't get too cocky.

No it doesn't. Regular old mass produced Mercedes motor 
Well of course corporate will tell you to take it easy on the motor. They would attempt to convince you to keep it under 4k rpms until the warranty lapses if they could get away with it 
Chill bro, they break the motor in at the factory. Thus, no requirement to break the motor in yourself.
I track my cars very frequently and I can tell you that a proper break in will come in handy mostly when you put a lot of pressure on the car.

More food for break-in thought...and the mentality my old high school small engine shop teacher preached back in the day. I've done this with all my new cars and have had zero mechanical issues across 200k+ miles.

Regardless if the engine is built on an assembly line by one person, or by a number of different people and robots, MB still says the engine requires break-in. Many people choose to ignore that, and say the manufacturer is being over-cautious.
