Trunk comparison: BMW X3 vs VW Taigo

Key Differences
The BMW X3 offers a significantly larger cargo area in length and width: with the seats folded down, the trunk of the X3 is +8.7 in (14%) longer, and with the first row of seats upright, it is +5.1 in (16%) longer.
At its narrowest point, the X3 is also +4.3 in (11%) wider, and the width of the trunk opening is +5.1 in (13%) larger on the X3. In contrast, the VW Taigo has a much greater trunk depth (loading edge to trunk floor): the Taigo leads by +7.9 in (1900%) over the X3 here.
Smaller differences: the trunk opening of the Taigo is only 0.4 in higher, and the loading edge of the Taigo is 2 in higher above the road.
Impact on Usability
The longer and wider cargo area in the BMW X3 makes it more practical for long or wide items (e.g., slats, skis, long boxes) and facilitates storing multiple suitcases or wide furniture pieces. The larger opening width simplifies loading and unloading bulky goods.
The significantly deeper loading area in the VW Taigo offers more "depth volume" behind the loading edge, which can be beneficial when stacking tall items or covering luggage under a cargo cover.
However, the loading edge of the Taigo is somewhat higher, which noticeably complicates lifting heavy loads compared to the X3.
Conclusion: Those who frequently transport long or wide loads or need a lot of floor space benefit from the BMW X3. Those who benefit from a deeper trunk floor for stackable cargo and can occasionally manage a higher loading edge will find a suitable compromise in the VW Taigo.
