A cargo carrier like a cargo box is a useful attachment for adding extra storage space for your vehicle, but it may negatively affect your gas mileage. Your fuel bills will indicate the changes in a tiny amount of money spent because of a roof box. Many people say that they notified a difference in gas mileage after installing a cargo box to their car.
Why does the change happen?
Although most cargo boxes are light in weight when they are empty, they drag the wind when they are in motion. Consequently, they can cause extra fuel consumption on your road trips. However, most cargo boxes have an aerodynamic design to reduce wind noise and decrease gas consumption on roads. Many people admit that there is little effect on gas consumption, but it is ignorable.
Do cargo boxes cause extra gas mileage? Yes, they do.
What can you do with a cargo carrier?
Different people will use cargo boxes for varying purposes like transporting gears, carrying luggage for road trips, moving homes, and more. As a result, you can find many different cargo carriers on the market for people to choose from for their demands. In general, hard-shell cargo boxes and soft cargo bags are two popular options for customers who want to have an added storage space on the roof of their vehicle.

When you use a cargo carrier, you put your stuff in it; thus, its weight increases dramatically. Your vehicle’s gravity center rises because of the cargo carrier. When you use a cargo box, you should pay attention to your driving with longer brakings, slower turnings.
On the market, cargo carriers have different shape designs, so they have varying gas mileage effects. Fortunately, aerodynamic cargo carriers can seriously eliminate wind dragging and decrease the costs of gas mileage.

According to many experts’ experiences, a cargo box can reduce almost 5 miles per gallon on your gas mileage. It means that your car will lose 5 miles per gallon gas consumption with an empty cargo box. If your cargo box is heavy-loaded, the effect may be more serious.
