Open Car Windows? You're Killing Your Mileage! The Surprising Truth Revealed

• Contrary to popular belief, driving with open car windows can reduce fuel efficiency more than using AC.
• Opening windows increases aerodynamic drag, forcing the engine to work harder and consume more fuel.
• Air rushing into the car disrupts its streamlined design, leading to higher fuel consumption.
• The negative impact on mileage is more pronounced at higher speeds due to increased air pressure.
• For better mileage, keep windows closed and use AC; it's often more fuel-efficient than open windows.
