Hi,

Interresting reading all along.

I think power runs are made at WOT.
I think best FE is around peak torque.
That is the conjunction of peak torque and WOT.
This calls for P&G on its own.
But also that acceleration implying less pumping loss are inherently more efficient.

Now that is for gas engines.

Diesel engines I'm not so sure.
Didn't find the proper way to use mine so far.
A very efficient drive to holidays last year (4.3 liters for 100 km between 70 to 76 mph on the highway) had to be totally ruined the day after when the car really lacked power to even pull out of its parking space and I ended up driving it at peak torque for the rest of the tank to get decent performance back.
It is a 150 000 miles car so must be carboned up badly already ...
