To some degree. Speed is inversely proportional to energy consumption due to air resistance. Slower is much more efficient.

This is the perfect Aktually comment. Something that's technically true but isn't a real consideration given the context.

To a certain degree. The engine resistance internally will be far greater at some point then the work at the wheels. The overall efficiency at slow speeds will be far worse.

Ie. A car traveling at 1kph while idling will only make 200km before the tank is empty. (20 hours). There always is a sweet spot. In farm equipment, tractor speeds are far lower and thus air resistance is negligible when compared to the work they do.
