The subject is engine fuel efficiency; nothing else. Notice huge gap in technology between two I6 engines built some fifteen years apart then read your above post again.

It seems like a reasonable trade-off.

Redline: Reports to date indicate widespread shortshifting of the S55 which would improve mpg versus redline shifting.
EPA: That's speculation but reasonable IMO.
HP: Yes, but you're not saying hp is greater factor than rpm where mpg is the subject, are you?
Some will certainly find the trade off reasonable while others will not. It is what it is.
