BackBox from mft – because aerodynamics make all the difference

Transporting items at the rear of the vehicle offers several key advantages over storing them on the roof. A rear box – i.e., a transport box for the towbar – is much easier to load than a roof box, which is only accessible overhead. At the same time, the center of gravity of the vehicle remains low, which has a positive effect on driving stability and handling.

But one of the biggest advantages is better aerodynamics. While a roof box disrupts the airflow on the vehicle roof and thus significantly increases air resistance, a rear box such as the BackBox from mft blends harmoniously into the shape of the vehicle. The result: less air turbulence, lower resistance – and thus lower energy consumption.

Rear box significantly reduces air resistance

A study commissioned in 2016 investigated the influence of the BackBox on the flow behavior of a simplified car model. The result was clear: the use of the rear box greatly reduced the flow turbulence behind the vehicle. The aerodynamic drag of the entire vehicle decreased by about 5 percent – despite the additional transport capacity!

By comparison, a roof box increased air resistance by around 35 percent in the same test environment. This means that driving with a rear box is more efficient than without, while driving with a roof box is significantly less efficient.

Travel more efficiently with lower consumption

The lower air resistance of the luggage box at the rear has a direct impact on fuel consumption and energy requirements in electric vehicles. The BackBox from mft offers a real advantage, especially for electric cars, where every kilometer of range counts. Thanks to its aerodynamic shape, the range remains virtually unchanged – a clear advantage over roof boxes, which often reduce the range by 10–20 percent.

The transport box for the towbar also impresses in everyday use:

  • Easy mounting without tools
  • Convenient loading and unloading at handle height
  • Secure hold on the towbar
  • No restriction of vehicle height – ideal for garages or parking garages

Conclusion: The BackBox from mft – aerodynamic, efficient, and comfortable

If you are looking for a practical, efficient, and aerodynamically optimized transport solution, the BackBox from mft is the perfect alternative to the classic roof box. Mounting it on the towbar means that the airflow over the vehicle remains undisturbed, fuel consumption is reduced, and loading and unloading is child’s play.

Less air resistance, lower fuel consumption, greater convenience – the rear box is the modern solution for safe and efficient transport at the rear of the vehicle.
