Being that "50-50" weight distribution (or as close to it as possible) has been one of the constants with BMW over time, i doubt they'll go Audi or Porsche on us and change that up. As far as the solid feel, I think that has more to do with the seals used and the tightness of the seams than just heavy materials being used to make up for that. Craftsmanship is where that makes a difference.

This comment made me laugh. Have you not seen M54->S54... minus the individual throttle bodies they are very similar. Same goes for the E36 with the S50 and M50 which are almost the same as well... The only car to break that mold has been the E9x with its unique engine.
S54 is a cast iron block. M54 was aluminium. The engines are completely different other than cylinder configuration.
