Aerodynamic Roof Cargo Boxes – A Guide

When it comes to making sure that you have enough space to bring everything you need with you on your next car trip, you might come to realize that you do not have enough space for everything in your trunk alone. This might be because the trunk of your car is relatively small and maybe you do not have the option of putting down the back seat.

Or, you might be facing this problem because you simply have too much stuff that you need to pack up. No matter what your reasons are, the first step to solving this problem is looking for more places where you can keep things safely stored. For instance, some cars allow you to store things on the roof, as long as you have a roof-mounted box that properly attaches to your car.

All Roof Cargo Boxes are designed to be Aerodynamic, however some are more Aerodynamic than others. Keep you MPG down and your cars performance up by choosing the most aerodynamic roof box for your needs, with the help of our guide.

What Types of Boxes Are There?

There are going to be two main types of roof boxes that you will want to look for. Some roof boxes are hard covered, with a durable lid to keep your belongings safe and sound during the trip. There are also soft boxes that are designed to be a little bit more flexible in terms of shape, which can be incredibly helpful if you are packing some large and non-conventionally shaped objects. While both of these boxes can get the job done, there are some jobs that are better suited to a specific type of roof box.

If you are looking for something that is designed to be aerodynamic, and are willing to sacrifice potential space, then you will want to look more toward the hard-covered roof boxes. These boxes also have more protection against rocks and pebbles kicked up by passing cars and trucks. On the other hand, the soft boxes allow for more flexibility in shape and are almost always significantly lighter. You will want to keep this in mind when you are looking for the perfect roof box for your car.
