Closed deck block (odds are it would share the same, if not extremely similar, casting with the S55).

I will say, I'm a bit confused over the logic some people use on this forum.
It would be one thing if we had BMW literature stating it was an open deck. But we don't. The absence of specificity in some BMW sources is not the same thing as contradictory information. So far, all of BMW's literature that mentions the block type at all have indicated a closed deck. Absolutely zero BMW sources have indicated an open deck.

And it's not mentioned in the tech training docs like it was on the S55, which made a point about detailing that, unlike the N55 open deck block, the S55 has a closed deck block. But, yes it has been written a few places that it has a closed deck. But it's NOT mentioned in the official press release nor in the tech training docs. And a new engine block is quite a big thing... They mention S55 pistons and other bits and pieces. But NOTHING about a larger/different turbo nor new engine block with a closed deck design... |

Didn't want to undercut the perceived value of the bigger-margin cars.

I don't understand why BMW would design a different block other than the S55's, that was closed deck, and still call it an N55. Why not just call it an S55B302 (compared to the F8x's S55B30)?

However, calling it a S55B20 would not work with the system BMW has for engine nomenclature. The 30 part denotes displacement in liters and as long as the M2 engine is a 3 liter it has to be a 30 as well. Examples: S52B30 - E36 M3 3.0 S52B32 - E36 M3 3.2 S54B32 - E46 M3 3.2 N53B25 - multiple models 2.5 liter N53B30 - multiple models 3.0 liter S38B36 - E34 M5 3.6 S38B38 - E34 M5 3.8 S63B44 - F10 M5 4.4 S65B40 - E9x M3 4.0 S65B44 - E92 M3 GTS 4.4 |

On another forum had contacted BMW. They got these responses, interesting part being no more "S" denotations. Quote:

http://www.bmwusa.com/bmw/M/M2/ So are you implying that there's a major faux-pas on the part of the website designer? Again, this is not a small detail in a big section of text. This is a major advertising point for the engine. |

Overboost could be done via a software. Doesn't necessarily require a hardware change.
