I think it is important to remember that mileage (fuel Economy) and volumetric efficiency are not the same. You may get your best mileage in specific freeway conditions at 40-50 mph and 1400-1600 rpm. However, Frank's formula applied to your 2016 Versa with its 3.29 inch piston stroke should be moving at a rate of about 1100 ft/min at 2000 RPM. That might be your greatest volumetric efficiency. But if you drove 65 mph or more to cruise at 2000 rpm your aero drag would be MUCH higher and you fuel economy would suffer.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
