Well, I suppose if they literally just rebadge the motor then perhaps I'd agree. But the liklihood that they will be able to squeeze 450hp+ out of an N55 with no changes other than to the ECU to me is basically zero. I mean sure you can probably do that with after market tune and mods today, but we are talking about a production motor with a warranty.

IMHO the "S55" (working name for now) will share less parts with an N55 than today's S63 shares with the N63. I suppose that isn't saying much, but my point is that I believe as time goes on, the M motors will likely veer more from the series motors. At the same time, I expect that the shortblock and probably much of the longblock will stay. Though I could easily see M specific heads and valvetrain for the F3x M3 and/or F2x 1M.
