Roofboxes are mounted on top of the car, which significantly increases air resistance. The high profile and placement means that the car has to work harder against the air currents, especially at higher speeds. Roofboxes increase the car’s air resistance by about 30 to 40%, leading to higher fuel consumption and increased costs. A backbox has much lower air resistance in the -5% to +15% range and can under certain conditions actually reduce drag, i.e., if the backbox is narrower than the width of the car and if its bottom sits above the car's underbody, this can result in a positive effect. This is because the car, together with the backbox, better releases the drag created behind the car, which reduces the overall air resistance and thereby the car's fuel consumption. 

IXTAbox offers various sizes of their backboxes, allowing users to choose a box that fits their needs while achieving optimal aerodynamic effect depending on their car.

Due to their placement, roofboxes can negatively affect the car’s handling and increase the risk of damage in an accident. IXTAbox is mounted low and securely behind the car, reducing the risk of damage to both the box and its contents in a collision. In a collision, most roof boxes on the market will either detach from their roof mounts or the contents will burst through the roof box, posing a risk to oncoming traffic and potentially causing devastating consequences.

A roofbox is often difficult to access. To reach your luggage, you may need to open the car door and stand on the vehicle's threshold, making it both cumbersome and unsafe. With IXTAbox you have easy access to all your luggage and equipment directly from ground level. Additionally, you still have full access to the car’s trunk.

When it comes to mounting, a roofbox often involves a time-consuming process that can take up to 30 minutes and usually requires two people. In contrast, IXTAbox can be mounted and dismounted in just a few seconds by one to two people, saving you both time and effort.

Roofboxes are limited by the type of roof mounts your car has and you might need to purchase different mounts for different cars. IXTAbox is flexible and fits most cars. The height above the ground can be adjusted, and the box can be positioned to ensure the car's license plate remains visible.

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 skies 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.
