Agree on the article and a different build process.
I do not believe manufacturers do a factory break-in, preliminary or otherwise. |
They do an initial break in. All cars are put on the dyno and revved out to 100 or so miles an hour. If you ever do a BMW factory tour or just watch a video of a factory tour you will see. It's not a full on break in, but it's still a preliminary one.
