Roof box BMW 5 Series –
Why a back box is the better choice 

The BMW 5 Series is known for its blend of performance, luxury, and comfort. But even with its spacious trunk, many owners consider adding a roof box for extra luggage space on family trips, golf weekends, or ski holidays. Before you mount a bulky plastic box on your BMW’s roof, it’s worth considering whether that’s the smartest choice.

Challenges with roof boxes on the BMW 5 Series

• Fuel efficiency: Roof boxes increase drag by up to 40%, which means higher fuel costs or shorter EV/hybrid range.

• Wind noise: The BMW 5 Series offers a quiet, refined cabin – but roof boxes generate turbulence that disturbs long drives.

• Accessibility: Lifting skis, strollers, or bags onto the roof is inconvenient and unsafe, especially in winter conditions.

• Aesthetics: A roof box compromises the sleek, executive design of the BMW 5 Series.
