Trunk comparison: VW ID.4 vs VW Tiguan Allspace

Key Differences

The VW Tiguan Allspace offers a longer cargo area with the seats folded down: it is 8.3 in (12%) longer, and with the first row of seats upright, it remains 7.1 in (19%) longer than the VW ID.4. In contrast, the VW ID.4 has significantly more trunk length with all seats upright: 18.5 in (100%) more than the Tiguan Allspace.

Additionally, the trunk opening of the ID.4 is 3.1 in (11%) higher and the depth between the loading edge and trunk floor in the ID.4 is 3.9 in (900%) greater than in the Tiguan Allspace.

Impact on Usability

For long items and loading configurations with folded seats, the Tiguan Allspace is advantageous: the longer cargo area with folded seats makes it easier to transport boards, furniture parts, or long luggage.

On the other hand, when the seats remain upright in normal use, the ID.4 offers significantly more usable trunk length, making it more practical for luggage, shopping trips, or travel bags.

The higher trunk opening of the ID.4 facilitates loading large/tall items, and the significantly greater depth (loading edge → trunk floor) creates more vertical storage space or better conceals luggage below the loading edge.

This can increase the perceived usable volume but makes reaching items at the very bottom somewhat more cumbersome. Smaller differences such as widths or the slightly higher loading edge of the Tiguan (≈1.2 in) are less noticeable in everyday use.

Conclusion: Tiguan Allspace = better for very long loads with folded seats. ID.4 = better for everyday use with upright seats, for taller items, and more concealed storage due to larger opening and deeper cargo floor.
