Maximum torque vs maximum fuel efficiency

[samygero]

Hello,

I would like to ask a question about engines in general.

Manufacturers give the maximum torque point for all engines.

I was wondering first of all if this maximum torque point is the same as maximum fuel efficiency point.

Secondly is it also the point where for one specific gear we have maximum fuel savings? Personnally I think not. I think that if we take the graphic of Torque/rpm the maximum fuel savings point is the intersection between the curve and the tangent passing through the origine. Am I clear enough?

thx
