Trunk comparison: BMW i4 vs VW Tiguan Allspace

Comparison of trunk dimensions for the BMW i4 and VW Tiguan Allspace

Key Differences (highlighted: >10%)

When comparing the trunk dimensions, several differences stand out. The BMW i4 offers significantly more cargo space with seats up: +20.1 in (109%) longer trunk than the VW Tiguan Allspace. The trunk depth (loading edge to trunk floor) is also significantly greater in the BMW: +3.9 in (900%).

The VW Tiguan Allspace, on the other hand, has advantages in width: the narrowest point of the trunk is +4.7 in (14%) wider and the width of the trunk opening is +7.9 in (21%) wider than the BMW. Additionally, the Tiguan's trunk with the first row of seats upright is +5.5 in (14%) longer than the BMW's.

Impact on Usability

These differences lead to specific pros and cons in everyday use:

BMW i4 – Advantages for longer items with full occupancy: The significantly longer trunk with seats up (+20.1 in) makes the i4 more practical when passengers remain inside but longer items (e.g., skis, long boxes) need to be transported. The considerably greater trunk depth (+3.9 in) provides more vertical space behind the loading edge, making it easier to store taller or bulky items. Additionally, the BMW's loading edge is lower (Tiguan +2.8 in), which facilitates loading heavy items.
VW Tiguan Allspace – Advantages for wide or bulky loads: The greater width at the narrowest point (+4.7 in) and the significantly larger opening width (+7.9 in) make the Tiguan overall more suitable for wide or awkward items that must fit through the opening (e.g., furniture parts, strollers, wide boxes). With seats folded down, the Tiguan offers a slightly longer cargo space (+5.5 in), which helps when transporting large volumes with an empty rear bench.
Practical Conclusion: If you often transport longer items with full occupancy or need to store tall loads behind the loading edge, the BMW i4 is more advantageous in daily use. If you frequently load and unload wide or bulky items and require a generous opening and interior width, the VW Tiguan Allspace is the more practical choice.
