If not the exact same process, I am sure it is similar to PTWA, yes.

But that does nothing to explain away the fact that we'd still be either looking at only 1.4mm between bores (which is roughly 1/4 of what the GT500 engine has, for example), or we have a brand new BMW engine architecture for the first time in decades. Either would be a huge, shocking surprise as far as I am concerned.

One more thing: in the latter case is true, this engine is not an N55 derivative so why was BMW compelled to call it S55?

I can't make any of this add up in my head. I remain very curious to know the detailed dimensions of this engine block. I'd sure like to turn off my skepticism and get down to celebrating this newly designed engine.
