We can compare any number of interesting cases including motorcycles, turbocharging, and so forth all day long. Great. But all we need is one counter example to disprove the original statement.

The genesis of the discussion was regarding BMW's inline architecture, what might have kept it the way it was for so long and what might be prompting a new design now. The suggestion was that stroke needed to be a certain length to get a certain result. If we are now saying that this limitation applies only within the confines of some other parameters, it obviously changes the entire discussion. And clearly we then need to define what those parameters are and how they are being restricted to draw any meaningful conclusion.
IMHO stroke isn't the ONE factor that can be isolated and all other parametres be different.

Other parametres means a identical engine, apart from bore/stroke ratio. Same cr, same volume etc. How can that be subjective?

Are you still seriously saying that comparing two very different engines Will tell us anything about different bore/stroke ratios?
