Conversely, when driving at speeds above 80 kilometers per hour, it’s more fuel-efficient to keep the windows closed and use air conditioning. Opening windows at high speeds creates aerodynamic drag, which increases fuel consumption.
Why This Trick Works:
Air Conditioning and Fuel Consumption: Air conditioners can increase fuel consumption by up to 10%. By managing its use wisely, you can conserve fuel.
Aerodynamic Efficiency: At high speeds, open windows disrupt the vehicle’s aerodynamics, leading to higher fuel use. Keeping windows closed and using air conditioning at these speeds is more efficient.
Additional Fuel-Saving Tips:
Avoid Frequent Acceleration and Deceleration: These actions significantly increase fuel consumption. Try to maintain a constant speed.
Steady Driving: Avoid sudden braking and acceleration to conserve fuel.
Potential Savings:
Utilizing the window trick, especially on long journeys, can lead to substantial savings. Tests have shown that you can save up to 35 euros per tank of fuel on a long-distance trip by using this method.
