    Using such a map, one can find the efficiency of the engine at various combinations of rpm, torque, etc. During the heart beat (acceleration) phase of pulse and glide, the efficiency is near maximal thanks to the high torque and far of this energy is stored as K.E. of the moving vehicle.

    Engines operating near their torque peak are more efficient . . . . . engines with wide torque peak range are therefore more likely to be more efficient in the real world.

    not really we have heaps of trucks that have huge amounts of torque and use **** loads of fuel. I still prefer my old petrol 90 series less torque than the diesel model heaps more road speed

    Not necessarily. Much more involved/.

    Including gearing, if Diesel or gasoline. If naturally aspirated or forced induction.

     Even if same  displacement.

    Some hi revving motors are more efficient. Need more gears, though

    .  EDIT: Diesel efficiency is also because of the higher Heat  Content of Diesel fuel v. Gasoline,. As well as 14:1 compression, or better, it also  burns it more efficiently.

    Not as simple as that. Diesels are more efficient, primarily due to higher compression ratio allowing more work to be done from each fuel charge burnt. Since diesels have a lower max rev range theyproduce more torque at lower revs than petrol engines for a similar amount of fuel. It's the compression ratio that makes the difference.

    more torque , more fuel ...

    Sone people say yes and cite diesels as proof. This is not strictly true. Diesels do have high torque but it is the chemical reaction that releases more energy per gallon than petrol that is responsible not the higher torque.

    This is far from a yes/no answer.   There are engines, vehicles and situations that effect the answer.

    Yes as they will pull a higher gear at lower revs. Diesels are a prime example using 15−20% less fuel.

    not usually, 'torque' is usually associated with a larger displacement engine ...............
