"Know when to close the windows. At highway speeds,it’s more fuel-efficient to use internal venting or air conditioningthan to drive with the windows down, which can actually slow yourvehicle. At slower speeds, such as in the city, keep the windows downand avoid air conditioning, which uses more gas."

Looks like it is a speed dependent thing, then.
