That motor is a monster and that's expected, it being the successor to the S55. It's only naturally it's going to evolve into being more resilient and better performing.
When BMW tune it for the G82 M4, it's going be roller-coaster fast but it's a highly complicated motor, I would hate to own one out of warranty.
