Trunk comparison: BMW X5 vs VW Taigo

Main Differences
The BMW X5 offers significantly more cargo length: with the seats folded down, the trunk is 11.8 in (≈19%) longer, and with the first row of seats upright, it is 8.7 in (≈27%) longer than the VW Taigo. Additionally, the narrowest width of the X5 is 4.3 in (≈11%) larger, making it wider inside.
On the other hand, the VW Taigo has a significantly greater depth between the loading edge and the trunk floor: it is 7.5 in (≈1900%) "deeper" here.
The height of the trunk opening is the same for both models; the width of the X5's opening is 3.9 in (≈10%) larger — this is exactly 10% and was not highlighted as >10%. The loading edge of the X5 sits about 1.6 in (≈5%) higher above the ground.
Implications for Usability
Due to the greater cargo length of the BMW X5, longer items (e.g., furniture parts, long slats, or skis) can be accommodated more easily, both with folded and upright seats.
The greater narrow interior width of the X5 increases the likelihood of fitting wide or irregularly shaped items flat inside. Together, these points provide a clear advantage for transports requiring area and length.
The much larger depth difference in the VW Taigo means its trunk floor lies significantly deeper relative to the loading edge.
This creates more "vertical" storage space below the loading edge (good for stacking or taller items that should sit low), but can make loading bulky items more difficult because they must be lowered further.
Combined with the shorter cargo length and narrower spot, this reduces the Taigo's suitability for longer or wide cargo.
Practically, this means: For regular transport of longer or wider goods, the BMW X5 is better suited. If, however, items are preferred to sit deeper in the trunk (e.g., to reduce overall height), the Taigo can offer advantages due to its greater depth.
The slightly higher loading edge of the X5 (≈1.6 in) makes lifting heavy loads in slightly more strenuous but is secondary compared to the length and width advantages.
