Its weird, because the x5m/x6m still have S designated engines, but the 1M does not, so I would venture a guess to say there is much more work done to the tt v8 than there is the 1M N54. Otherwise, why wouldnt BMW call it an S engine?
Maybe someone has more details on this??
Sorry I probably confused matters more with my previous post. I do realize that the 1M does not have a "M" engine designed specifically for that car. It is essentially tuned (for more boost) transplant from the 335. What I was saying was that an "S" engine is basically a tuned 335 or N54 engine nothing more iircc.
