TIPS FROM GERALD
MYTH: DRIVING WITH THE WINDOWS OPEN TO STAY COOL SAVES GAS
According to Ford's "Driving Skills For Life" website, the power-robbing effect of air-conditioning compressors is less hurtful than the aerodynamic drag created by speeding down the road with the windows open, especially at highway speeds.
After accelerating to forty miles per hour, it is more fuel efficient to operate the air conditioner than to have the windows down. The turbulence caused by open windows will require more horsepower, thus causing the vehicle to consume more fuel to maintain a steady speed.
The website recommends using the recirculation feature, because it is more efficient to cool already cool air from the interior than outside air. Another good tip is to run the vent/fan setting once the interior cools down.
