For more on marking an answer as the "Best Answer", please visit our FAQ.Temperature, vehicle speed, vehicle size, and wind velocity and direction are all factors that will affect drag related increases in fuel consumption when windows are open. However A/C uses a significant quantity of fuel (I would hardly call a 10%-20% reduction in fuel economy as a "small amount") and for many cars A/C is demonstrably less fuel efficient than open windows even at speeds in excess of 60mph.
