there could be some logic reasons and I know RPM and wind resistance but any different graphs with different intervals? or any research show exactly why? please

its all about efficiency really,many say that faster rpm = more fuel used ,but this obviously means ground covered in a faster time,when an internal combustion engine burns fuel it burns it most efficiently at a certain range of rpm ,drive within this range of rpm and you will have the best fuel economy,also bad gear change timings can make a difference,if you use heavy acceleration and change up the gears too quickly you will vastly reduce your mileage per gallon as the engine load will be too great.it all noils down to sensible driving really,avoid rapid acceleration and drive at a reasonable constant speed within the spped limits and you will be driving to what the car was designed for and it should be economical.

very simple.. it takes force(work) to move mass.. the faster you want to move the mass takes more force and the energy to make force comes from the fuel used
