Audi A4 Roof Box Rack and Bags

Audi A4 Roof Bag & Roof Rack Guide

The Audi A4 is a fun car to drive. It has a lot of power that lets you tear up the highway. However, some drivers have wished for more cargo space on their trips because the boot can’t hold everything they need. This is where cargo bags can help because they provide extra space to store your precious cargo in transit.

The cargo roof bag you get depends on the cargo capacity of your car, and the cargo capacity depends on the model of the A4 that you have. For example, the A4 Avant, which is the estate version, has a cargo space of 17.5 cubic feet, the All Road (the hatchback) has 24.2 cubic feet while the saloon variant has 17 cubic feet.

You also have to consider the width of the car, to avoid your cargo dangling on the sides when the cargo bag is wider. This should not happen very often as most cars are around the same width give or take a few centimetres, but for much smaller cars like the Audi A3, make sure to double check the size of the cargo bag or roof box.

Audi A4 Cargo Space

  •  Audi A4 Saloon – 12 cubic feet 
  •  Audi A4 Avant – 17.5 cubic feet 
  •  Audi A4 All Road – 24.2 cubic feet 

You also have to consider the total weight that your OEM roof rack can hold. If it is less than the weight of the roof cargo  bag plus its content, then you may have to get new roof racks. Lastly, don’t forget that the car itself has a limit to the cargo weight it can carry on the roof, which is 75kg for the Avant, for example.
