The secret is to understand that your drivetrain is effectively a load bearing surface. Friction is related to velocity (faster movement yields more friction per unit time), and input torque (since it's load bearing, input torque increases the normal force, thus increasing friction).

Imagine dragging a board across a floor. Now stack bricks on it, and it's harder to drag. Dragging the board is akin to the work your engine performs. Adding bricks corresponds to increased friction on the drivetrain. It takes more work to offset the additional friction you're producing by loading up the contact surfaces.

Kind of the long version of Toby's explanation.
