Roof box Tesla Model 3, Y and S – Why a back box is the smarter choice 

Tesla owners value efficiency, design, and quiet driving. Whether it’s the sporty Model 3, the practical Model Y, or the premium Model S, many drivers eventually look for extra storage space for family trips, sports gear, or longer journeys. A roof box might seem like the obvious option – but for EVs, it’s often the wrong choice.

The problems with roof boxes on Teslas

• Reduced range: Roof boxes can increase aerodynamic drag by up to 40%, cutting into driving range – one of the most important factors for EV owners.

• Noise: Teslas are engineered for near-silent driving, but a roof box creates wind turbulence that disturbs the calm cabin.

• Inconvenient loading: Placing skis, snowboards, or luggage on the roof is awkward and unsafe, especially in winter weather.

• Design mismatch: A bulky roof box doesn’t fit Tesla’s sleek, futuristic look.

Why a back box is better for Tesla owners

A towbar mounted cargo box like IXTAbox is built to solve these problems while adding practical, aerodynamic storage.

• Improved efficiency: Positioned at the rear, IXTAbox reduces drag by up to 5%, helping maximize range on long trips.

• Quiet ride: Less turbulence means the cabin remains peaceful – just as Tesla intended.

• Generous storage: Up to 390 liters of capacity, perfect for skis, snowboards, golf clubs, or family luggage.

• Easy access: Mounted at waist height for safe and convenient packing.

• Premium durability: Made in Sweden from aluminum and stainless steel, IXTAbox matches Tesla’s high-quality build.
