The ASPHALTKIND Roof Box “Cropfiber”

Germany’s fastest roof box

Currently, to create more cargo space in cars, you have to resort to heavy, bulky and not very handy roof boxes. This always requires concessions in terms of aerodynamics and speed, weight, stability and appearance.

We wanted to change that and have developed the perfect roof box. Our ASPHALTKIND box achieves top values in all areas and thus sets completely new standards for comfortable travelling.


Germany’s fastest roof box.

For strong headwinds: light, stable, aerodynamic.
More information


Range optimized.

Orientation in the basic shape to a drop of water: results in a CW value of 0.11.


Light. Lighter. Most stable.

For higher payload and lower centre of gravity.


Lines that fit.

Characterized by a tense clear lines. The box is in motion, although it stands.


For speed. For range.

The most aerodynamic shape in nature is that of a drop. And since our roof box is based on this, it achieves a top CW value of 0.11. To achieve this, we spent over 200 hours of testing and simulations.

First premise: The car’s aerodynamics must not be compromised. In short: The roof box is suitable for long and demanding routes. Even for the Nordschleife.

Material fiber composite:

Benchmark for low weight with high stability.

Only by using fiber composites you can achieve high stability with very low weight. By using CO2-neutral Cropfiber fibers, we even achieve this without compromising the planet.

Over 16 hours of production time for perfect quality and appearance.

With a weight of less than 17 kilograms for more stability at high speeds. For overtaking maneuvers. For your safety.

Also for everyday life:

Open at the touch of a button.

We are the pioneer for the entire market: To make the handling of our roof box even simpler, we have installed an electric locking system. This allows the box to be opened with a simple push of a button.

Gone are the days when you have to “fiddle” with a small key on the box.

Tensioned lines

By focusing on clear, taut lines and dispensing with beads and edges, we achieve the “in motion even though the roof box is standing” effect. With external dimensions of 215 x 90 x 32 cm, the proportions and your luggage fit 1A.  

Cargo space miracle

More than 400 liters of cargo space are available for everyday life and especially for your adventures. The roof box can be opened in less than 2 seconds. The perfect trunk replacement. Also for everyday use. 

The Design: Benchmark.

By working with experienced automotive designers, we have broken new ground and achieved the goal: the roof box becomes part of the car. It complies with the principles of automotive design.

Development process:

Safety & Everyday Suitability.

To develop the perfect roof box, we worked for over 2 years on aerodynamics, weight, stability and design. This resulted in over 200 simulation hours and more than 15,000 test kilometers including everyday tests. Particularly significant here: the test drives to Berlin, Hamburg, Zuffenhausen and the Black Forest.
