Thule Arcos Box M
medium hard-shell towbar cargo carrier box
Thule Arcos gives you plenty of loading space at the rear of your car, keeping the roof free to reduce wind resistance or to carry other loads. The design of Thule Arcos is modern and streamlined, with an aerodynamic wing shape that makes it feel like a natural extension of the vehicle.

Crash tests
We conduct multiple crash tests at different speeds and weights to see how the racks and cargo carrier protects its contents and the vehicle from damage.

Wear and tear simulations
Specialized tests that are used to evaluate the cargo carriers over time, to assess their durability and long-term performance.

Exposure tests
To evaluate the performance of cargo carriers under conditions that might be encountered during use, we expose them to extreme heat, cold, damp, sunlight and chemicals.
