If the purpose of opening the window while driving is to save fuel, it’s a misconception – Photo: Unsplash/Josh Regis/TikTok
Josh Regis, 34, lives in the US, is an automotive engineer with 18 years of experience, and has 18,000 followers on TikTok. He pointed out several misconceptions regarding the use of cars. One of the ideas is that opening the windows instead of turning on the air conditioner while driving will help save fuel.
However, in a video viewed 728,000 times, he said: “Did you know you burn more gas when you drive with the windows down than when you drive with the A/C on?”
This is shocking information to many, as “experience” and drivers whisper to each other the opposite.
Explaining the reason for this, Regis said the problem lay in drag: “Driving at high speed with the windows open, the car will have a harder time when there is snow on the road, which means more gas will be burned.”
Another user said: “If so, the problem is in the speed. If the speed is higher than 80lm/h, turn on the air conditioner. If the speed is lower, open the window.”
Another agreed: “It all depends on driving in the city or on the highway. If you go on the highway, close the windows to limit drag. If you go into the city, open the door.” That’s it. If you care about fuel economy”.
Meanwhile, there are also some skeptics: “But my car uses less gas when I open the window”.
