Trunk comparison: BMW X3 vs VW Tiguan Allspace

Key Differences

In direct comparison, two differences stand out clearly: The VW Tiguan Allspace offers with the first row of seats upright a cargo space that is 6.7 in (+18%) longer than the BMW X3. In contrast, the BMW X3 has a trunk that is with all seats fully upright 18.9 in (+102%) larger than the Tiguan Allspace.

These two values are clearly above the 10% threshold and are therefore the most relevant differences for practical use.

Implications for Usability

The longer cargo length of the Tiguan Allspace with the first row upright makes it more flexible for longer items when seats are partially or front seats are not folded down — for example, during transports where the seat rows are mostly used but longer items still need to be loaded.

The Tiguan is the more practical choice here for long loads with a partially occupied vehicle.

The significantly larger trunk of the BMW X3 with all seats upright, on the other hand, speaks for better storage space with full passenger occupancy: Those who often travel with multiple passengers and still want to carry a lot of luggage (e.g., trips with full occupancy) benefit from the X3.

Other, smaller differences act as complements: The trunk opening of the X3 is nominally 2.8 in higher (≈10%), which makes loading tall items easier; the loading edge of the Tiguan is also 2.8 in higher above the ground (≈10%), which can make lifting heavy loads somewhat more difficult.

The depth of both trunks is the same, the narrowest width is slightly larger in the X3 (10%), the opening width slightly favors the Tiguan (+2%). These points are less pronounced than the two mentioned above but can matter for special requirements (very tall items, heavy lifting, wide loads).

Conclusion: Tiguan Allspace = advantage for longer items without fully folding seats. BMW X3 = clear advantage in cargo volume when all seats are used and a lot of luggage still needs to be carried.
