From St. Moritz via Hamburg to the Nürburgring Nordschleife

September 2022 was a very special month for our company the Cropfiber GmbH with its brand ASPHALTKIND!

Right at the beginning of the month we celebrated the official market launch of our ASPHALTKIND roof box “Cropfiber” with a trip to St. Moritz (Switzerland) to the Kilomètre Lancé, the “Top international Sprint for Record Breaking Vehicles”.
After that, we headed towards Hamburg with a short stop at beautiful mountain serpentines past Munich and Ingolstadt! There we visited some hotspots for photos and exposed the roof box to curious looks.

Driving over the legendary track in the Eifel is a must for all car manufacturers, such as BMW, Audi, Porsche, Mercedes and now also Tesla. So also exactly the right environment for our ASPHALTKIND roof box! Between prototypes, tourist drives and trackday enthusiasts we went to the Ring in best conditions. Our goal: to achieve the proof that our roof box is suitable for high speeds.

Our race driver, equipped with helmet and racing overalls, who knows the track inside out, did not spare the material. Both the car and the roof box experienced great lateral and longitudinal dynamic forces, which cannot be realized in normal road traffic.

Per Sport Chrono Package stopped 08:20 minutes lap time and the quite worn road tire flanks underline the (cornering) speeds that were achieved. Of course, this did not go unnoticed by the spectators as well as photographers at the Brünnchen, the Swallowtail and Caracciola Carousel and we received a lot of positive feedback and conversation besides photos!

We can only give a limited answer to the most frequently asked question: “How fast can you drive with a roof box?” The maximum speed with roof box on the Nordschleife, which we could reach performance-wise on the short stretch, was 220km/h. The cornering speeds were minimally below that we did not end up in the guardrail. The deceleration values, i.e. braking from high speeds towards a tight curve radius was impressive and exactly the right terrain for the big brakes. So the perfect roof box for a sports car, like a Porsche 911!

True to our credo: “Developed and tested on a sports car. Built for station wagon, sedan, SUV and coupe, as well as the left lane.”, we can now proudly announce: The ASPHALTKIND roof box “Cropfiber” is Approved by Nordschleife. And to the curious looks in St. Moritz and Hamburg. Our goal at the beginning of the development of the best roof box on the market was that we focus on 

aerodynamics, stability, weight and design. We can now proudly announce that we have achieved this. With our performance roof box you can drive top speeds: 160 km/h, 200 km/h and more. In any case, the roof box allows you to drive faster than 130 km/h.

This is exactly what has convinced a group of customers for whom we have been realizing individualized roof boxes according to customer requirements in our internal production facility in Dortmund (Germany) for several weeks now.

A few production slots are still available for prompt delivery. Accordingly, do not hesitate for long and, like the 911 with roof box, be very fast and order!
