Aerodynamic cargo box for EVs – Smarter storage for electric cars 

Electric vehicle owners know that aerodynamics equals range. Every extra bit of drag makes your battery work harder and reduces how far you can travel on a single charge. That’s why choosing the right cargo box is so important – especially if you drive an EV like a Tesla, Polestar, or BMW i-series.

The problem with traditional roof boxes

• High drag: Roof boxes can increase aerodynamic resistance by up to 40%, draining range significantly.

• Noise: At highway speeds, roof boxes generate wind turbulence, disturbing the quiet ride EVs are known for.

• Accessibility: Loading heavy items onto the roof is inconvenient, especially in winter conditions.

Why aerodynamics matter more for EVs

Unlike petrol cars, EVs don’t benefit from quick refueling. Maintaining range is crucial – and that means avoiding unnecessary aerodynamic penalties. The wrong cargo solution could cut your trip short or force you into more charging stops.

The smarter solution: rear mounted cargo boxes

Back boxes, mounted on the towbar at the rear of the car, are far more aerodynamic. Positioned behind the vehicle, they follow the car’s natural shape and can even reduce drag by up to 5%.

Key benefits for EV owners:

• Maximized range: Less resistance = longer trips on a single charge.

• Quieter drive: Less turbulence keeps the cabin peaceful.

• Easy loading: Mounted at waist height for safe, convenient access.

• Generous capacity: Up to 390 liters for skis, camping gear, or family luggage.

Smarter aerodynamics, smarter storage

For EV drivers, the best cargo box isn’t a roof box at all. It’s an aerodynamic back box – combining efficiency, practicality, and design in one solution.
