Is that right and/or have your informations have changed until now?
And what does that meen:
- F80 M3 simply with an reinforced 3.0ltr. N55 with an modified TwinScroll- Turbosystem ... and the F8x M4 with the same base engine but more capacity (3.2ltr. to 3.6ltr.) or the same capacity and an more advanced Turbosystem like Bi- or TriTurbo(from the N57-S).
- F80 M3 simply with an reinforced 3.0ltr. N55 with an modified TwinScroll- Turbosystem ... and the F8x M3 with the rumored S63Tü derivated 3.3ltr.V6 BiTurbo.
- F80 M3 comes with an interim engine and gets the new engine when the F82 M4 debuts. As interim engine theoretically comes into question ... the reinforced and tuned N55 or an slightly modified S65.
Thanks and greets
I highly doubt that BMW would use anything but the same engine across the entire F8X platform. The only wrinkle that I would expect in the development of this engine would be to see it in the X3M before it made its way into the M3 or M4, but that doesn't seem to be happening either.
