Yes, I know the importance of properly breaking in the engine on the C63s automobiles but I would be very interested in hearing the technical aspect of the importance of this process from one of the highly regarded AMG engine builders on the "Who built your real AMG" thread that was started on this forum. It has been immensely popular with over 27,000 views. Obviously there are many members on this forum that could give us good insight and I would welcome your input. It would be very special if one of the actual AMG engine builders from the AMG plant in Affalterbach Germany could share some of their expertise with us. I would assume some of the AMG engine builders participate on this forum. I'm sure I speak for many of the forum members when I say that we would LOVE to hear from the experts who meticulously assemble "our" AMG engines.

Probably only going to find them on the AMG PL forum if that.

Break-in of modern engines is largely pointless. In the MB system it is more about learning in all the adaptation values for the entire powertrain, not physically wearing in of engine components. As good and consistent as machining is now, the old school idea of surface finishes mating up is no longer a thing. But with the computers compensating for so many different variables and many of them taking several cycles to learn completely, they want you to drive the car "normally" to teach in all the shifting points and things before you go full blast.

I also don't think the engine builders are hanging out here. At a minimum the piston rings still have to wear in to make a proper seal. That usually takes about 200 miles of moderate driving, but the cylinders themselves don't really need wear in. The NANOSLIDE cylinder wall technology they use and pioneered is pretty amazing and the cylinders are honed with a simulated cylinder head properly torqued to the block, so the metals are expanded just like they are once the engine is fully assembled. I agree there are a lot of learning algorithms in modern cars that need to learn their base parameters before things perform as designed. These cars clearly open up after a few thousand miles for example. I don't feel the car had full performance until about 8000 miles. Having done the private factory tour, getting a close up on how they build the engines and personally meeting some of the engine builders (unfortunately mine wasn't in at the time) I can tell you they never run the engine until the completed car rolls off the assembly line. That's when it gets fired up for the very first time. AMG only performs a so called cold test. The final engine is hooked up to a testing rig and an electric motor spins it up to about 3000 rpm, while a number of tests are being run to make sure everything was put together properly and the ECU is working as designed. However, no actual ignition is taking place and no fuel is in the system, but they perform a compression test. These engines are never run in other than the cold test which takes less than a minute.

I am under the break in period , at just 200 Miles.
I keep my Speed under 80MPH
- At lights I will gas it a bit , then allow the engine to downshift automatically.
-Basically break in is a bit of common sense and practical driving for a newly built performance engine.

Allow the Oil and Parts to properly lube and set in , no need in going to ***** to walls after purchase.
