No. Because that immediately makes the whole thing subjective. How do you mathematically model "comparable"? You can't. You need to define what that means first. And that definition will ultimately boil down to the need for a more specific hypothesis.
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.
