Marketing absolutely does not decide which technical approach will be implemented or how a particular approach will be used to reach a top level product design goal. Engine engineers and designers are far far too clever and knowledgeable to be swayed by poor use of jargon by end users. Brand new engines are again $100M or hundereds of millions of dollars. Folks don't screw around with poor jargon or a misunderstanding of a very fine technical details with this kind of money at a company of this size.

ALL of these have the same OR HIGHER rev limits. Note that they are all Japanese!!! Yep the Japs accept the shortcomings of boost threshold but love the turbo hit.

But they appear in significantly different end products right?

Don't state as fact if you won't discuss. I'd love to see the proof, not some BS gossip from a magazine...

All I am saying is that an I6 is inherently less expensive than a similar V8. I have also shown how simple economy of scale makes high volume parts and systems less expensive than low volume ones. In this case, for BMW M, the I6 is the least expensive option, mostly due to economy of scale. I would also bet that at the same volume an I6 would be less expensive than a V6. There are other advantages of a V6 in terms of compactness that for some purposes may make that a necessity. The I6 physically may not fit.
