Traditional roofboxes create significant drag. Their bulky, high-mounted design increases a car’s air resistance by 30–40%, especially at high speeds. This leads to higher fuel consumption, more CO₂ emissions, and greater long-term driving costs.

Backboxes are much more aerodynamic. With air resistance typically in the -5% to +15% range, a backbox offers a smarter alternative for fuel economy. In fact, under the right conditions— when the backbox is narrower than the car and positioned above the underbody— it can actually reduce drag. By smoothing airflow and improving how the car releases turbulence, a backbox can lower fuel consumption and improve efficiency.

IXTAbox takes this advantage further. Designed with aerodynamics in mind, they are available in several sizes, allowing you to match the perfect storage solution to your vehicle.

Roofboxes can compromise both safety and stability. Their high placement raises the car’s centre of gravity, which negatively affects handling. In an accident, roofboxes are at risk of detaching from their mounts, or worse, the contents can burst out, creating a hazard for oncoming traffic and increasing the chance of serious damage.

IXTAbox is designed with safety in mind. Mounted low and securely behind the car, it reduces the risk of detachment and protects both the box and its contents during a collision. This safer positioning not only minimises potential damage but also enhances driving stability,

Roofboxes can be difficult to clean and can make both you and the car dirty when accessing your luggage. IXTAbox is easy to clean with a hose or pressure washer and keeps both you and your car clean, even when packing dirty or wet items.

A roofbox has limited use and takes up space when not in use. IXTAbox is designed for multiple purposes, from transporting bikes, skis and camping gear to serving as storage at home. You can even mount packages with longer skis or bike racks on top of the IXTAbox.

Roofboxes create increased air resistance, leading to higher noise levels inside the car. This increased airflow around the roofbox generates significant wind noise, especially at higher speeds, which can be disturbing and reduce driving comfort.

IXTAbox is designed to minimize this issue. Mounted behind the car, IXTAbox is less affected by direct airflow, greatly reducing turbulence and wind noise. As a result, IXTAbox does not increase the noise level inside the car, even at higher speeds. This allows you to enjoy a more quiet and comfortable ride without annoying background noise. For a better driving experience and increased comfort, IXTAbox is a superior alternative to a roofbox.

IXTAbox is made of high-quality, recyclable materials in Sweden, ensuring long durability and lifespan. Roofboxes are often manufactured in low-cost countries with materials that do not always meet the same standards.
