According to the EPA, crosswinds introduce lateral rolling-resistance to the tires — think of the steering corrections needed to maintain a straight line — and they increase aerodynamic drag in directions a car isn’t designed to handle, both of which affect gas mileage. Greg Fadler, an aerodynamics engineer at GM, expounded: A 14-mph crosswind on a car traveling at 55 mph can affect its drag coefficient enough to increase fuel consumption 13 percent, he said.
