Almost. Its just not the significant part. Formula is Force = coefficient of friction x N where N is to all intents the mass. COF is constant. As explained above the delta due to eg 100kg mass is negligible vs drivetrain friction and other factors like wind drag. Add a passenger and virtually no change in fuel consumption for instance.
This assumes a constant velocity.
In situations where the mass is continually accelerated at low velocity it will make a tangible difference ie in town. So I would expect the gap between 4wd and 2wd to close as speed increases due to the drag going up power 4 to velocity and normally at a constant velocity on the motorway so no power consumed in accelerating formula is F = ma ie mass x acceleration. No acceleration then no Force.
