Air
It presents a significant drawback. In numerous regions, it’s not customary for households to possess air conditioning. Conversely, automobiles typically come equipped with built-in air conditioning, a feature greatly appreciated during scorching summer days. While it provides a welcome respite from the heat, there is a notable downside.
The air conditioning guzzles gasoline.

Fuel
Are you aiming to economize on fuel expenses or extend your driving range without needing to refuel? Consider switching off the air conditioning! According to research highlighted by Libelle, manual AC systems consume more gasoline during warm weather compared to regular days. On a hot day, the AC could consume up to 12.5 percent of your fuel supply. A quick calculation reveals that out of the 70 liters of gasoline you fill your tank with, approximately 8.75 liters are consumed by the AC. However, if you have an automatic AC, this consumption is reduced by half.

Open the windows
A manual air conditioning system poses further drawbacks for your fuel consumption. Within city limits, the AC consumes significantly more gasoline compared to rural areas. Since driving speeds are typically lower in urban settings, opting to roll down a window for some fresh air could suffice. Conversely, when cruising on a highway, utilizing your car’s AC is advisable. Opening windows at high speeds increases air resistance, leading to greater fuel consumption. It’s essentially a choice between two unfavorable options, but prioritizing the air conditioning while highway driving is more favorable for your fuel efficiency. As a fuel consumer, your AC not only strains your vehicle but also drains your finances.

Bad for your car, bad for you
However, next to your wallet, the AC can also be bad for your health. Air conditioning makes it very cool in your car and that is great in the summer, but it could make you sick. The temperature inside and outside of the car differs so much that the change in temperature can make you sick. This does, however, have a very simple solution: turn the AC off five minutes before you arrive at your destination. That way you can gradually get used to the outside temperature again before you get out of the car. You can, of course, also leave the AC off when you drive to save you both illness and fuel.
