Trunk comparison: BMW X2 vs VW Tiguan Allspace

Key Differences and Impact on Usability
The VW Tiguan Allspace offers a significantly longer cargo space with the seats folded down: +9.4 in (14%) compared to the BMW X2. This makes the Tiguan more practical for long items (e.g., skis, long furniture parts) or when you need a large loading area without the rear seats.
Even with the first row of seats upright, the Tiguan Allspace has an advantage: +7.5 in (20%) more cargo space. This means: if you carry several passengers, there is more room for longer luggage behind the seats in the Tiguan.
In the opposite use case — all seats upright — the BMW X2 is clearly ahead: +18.1 in (98%) longer trunk than the Tiguan Allspace. For everyday use with five people and regular luggage (shopping, suitcases, shopping bags), the X2 thus offers significantly more immediately usable storage space.
The depth of the trunk (loading edge to trunk floor) is significantly larger in the BMW X2 with +3.5 in (800%).
Practically, this means: the X2 has a deeper loading well, which allows for more vertical volume and a deeper shelf, but can also make lifting heavy items in and out somewhat more difficult and small items tend to stay in the well.
The width of the trunk opening is +5.9 in (15%) larger in the Tiguan Allspace than in the BMW X2. A wider opening significantly facilitates loading wide or bulky items.
Smaller differences under 10%: The opening height is 2.4 in (9%) higher in the Tiguan Allspace and the loading edge of the BMW X2 is 1.2 in (4%) higher above the road.
These values improve handling (higher opening = better for tall items; lower loading edge = easier lifting), but are less decisive than the differences highlighted above.
Summary briefly: For long or bulky loads with folded seats and for wide cargo, the VW Tiguan Allspace is often more practical.
For daily use with full seating and larger immediately usable luggage volume, the BMW X2 scores. The deeper loading well of the X2 increases volume but can make handling heavy loads more difficult.
