Of course it does... Did I say it didn't?

Yeah I know...

Yeah knew that too. In fact I was the one who said that you should show BSFC figures because BMEP is not directly in relation with thermal efficiency.

No. But I drive like most danes do. I think you are reading too much into this, I just stated that the average RPM you stated didn't relate properly to me or most driving danes.

Did I ask you to accept the way I drive as a point of testing or developement? No I simply said that you should except that I do not sit on the average (instead of suggesting ways that I should change so that I do sit at average).

Thats all good and well but the info I have is based on WOT. Besides if your bottom-end technology is actually helping to achieve the efficiency then it should also show under WOT testing.

I'm not sorry. I would much rather have an eventfull dynamic journey then droning on at 100km/h. Besides if I have to go far I can cruise at 130km/h (legally)

Still waiting for your own engine design thread !!

I wasn't aware I was interrogating anyone
I do except the actual data that the tests showed, I do not question that at all. I question the statement made that a single point proves the revetec engine to be extremely efficient (beyond a doubt...?).
I disapprove of Simpsons Tiger-repellant-stone logic.
