Don't get hung up on engine size.
Its irrelevant, what matters is bearing journal area relative to thrust.
Simply better technology meaning more power from less and more reliably.
High output small diesels have been around for years in Europe.
We haven't been able to use them due to our high sulfur content in our fuel which is slowly improving.
when you walk behind any modern diesel you can smell the sulfur but my old cruiser just smells like burnt diesel.
Just being burnt so much more efficiently.
