Of course, our roof boxes are designed to be streamlined, but even the most streamlined roof box causes a certain level of wind drag because of its position on the roof. But the back of the car is a place almost without wind resistance, so a rear cargo carriers can even have a negative wind drag! This means that you can actually get further with the same amount of gas or electricity as a vehicle with a roof cargo box.
