    Same speed = same RPM, regardless of load / air resistance. Unless they have to drive in a lower gear to make it work, but I doubt that

      You’re right RPM is tied directly to wheel speed. There is increased fuel consumption because the load on the engine is higher.

      More surface area = more drag. A big ol non aerodynamic cube will definitely be adding more drag. Other than that, yeah load doesn’t really effect mpg

        Yeah for sure. I’m just saying that the engine RPM won’t be affected as the original comment implied. Drag and mpg will definitely be higher.
