How to pick the right cargo box for your car model
How to pick the right cargo box for your car model
Thinking about adding extra storage to your vehicle? Most people immediately picture a roof box. But before you start looking at roof racks and complicated mounts, there’s a smarter and more practical option to consider – the rear mounted cargo box, also known as a backbox.
Why choose a backbox instead of a roof box?
Roof boxes have long been the standard solution for extra storage, but they come with a number of drawbacks:
-
Hard to reach – lifting gear overhead in cold or wet conditions is both inconvenient and risky.
-
Poor aerodynamics – roof boxes increase drag and fuel consumption.
-
Noise – turbulence on the roof creates annoying cabin noise during longer drives.
-
Complicated installation – requires roof rails or crossbars, which not all cars have.
A backbox solves these issues in one go. Mounted at the rear of the car, it offers all the space you need with none of the classic roof box frustrations:
-
Easy access: Load and unload at waist height – no climbing, no stretching.
-
Universal fit: Works with most vehicles that have a tow hitch – no roof bars required.
-
Aerodynamic advantage: Positioned behind the car, reducing air drag and wind noise.
Finding the right size for your car 📏
When choosing a backbox, size and fit matter for both capacity and comfort.
1. Think about your gear
Ask yourself: what do you need the box for?
-
For sports equipment, camping gear, or regular luggage, around 350 liters is often enough.
-
If you’re carrying skis or snowboards, prioritize length – most boxes fit gear up to 190 cm, and some models allow longer items to be mounted on top of the lid.
2. Measure your car
-
Width: Measure the width of your car (excluding mirrors). Most backboxes are designed not to exceed the legal maximum width of 2.4 meters.
-
Length: Choose a box that complements your vehicle’s size and your cargo needs, typically between 170–190 cm.
-
Height & trunk access: Ensure the box height allows your trunk or tailgate to open without obstruction. Premium models like IXTAbox have adjustable mounting solutions for different vehicle heights.
Features worth considering ✔️
When comparing models, look for details that make a big difference in everyday use:
-
Smart shape & volume: Avoid awkward designs – a consistent, rectangular interior makes packing easier.
-
Mounting system: Quick, tool-free installation on the tow hitch saves time and effort.
-
Integrated safety lights: Rear lights connected to your car’s system improve visibility and safety.
-
Internal organization: Dividers or optional accessories help keep your gear organized.
-
Weight capacity: Check the maximum load – premium backboxes can handle up to 100 kg.
