Roof box for small cars – Why a back box is the smarter choice 

Drivers of compact cars often face the challenge of limited luggage space. A roof box is usually the first idea when more storage is needed – but for smaller vehicles, this isn’t always the most practical solution.

The downsides of roof boxes on small cars

• Fuel consumption: Roof boxes increase drag by up to 40%, which has an even bigger impact on smaller engines and EV ranges.

• Noise: Smaller cars are often less insulated than SUVs, meaning roof box turbulence is more noticeable inside the cabin.

• Difficult handling: Adding weight high on the roof affects stability and driving dynamics.

• Accessibility: Lifting heavy luggage or sports gear onto the roof is inconvenient, especially on compact cars with limited roof load capacity.

Why a back box works better on small cars

A towbar mounted cargo box like IXTAbox is perfectly suited for compact vehicles.
