Trunk comparison: VW ID.4 vs VW T-Cross

Key Differences and Implications for Usability

The VW ID.4 offers significantly more cargo space: with the seats folded down, the trunk is 9.4 in (+17%) longer, and with the first row upright, it is even 11 in (+42%) longer than the VW T-Cross. This makes the ID.4 noticeably better for longer or bulky loads (e.g., furniture, long packages, bicycles without front wheels): it accommodates longer items more easily and allows more flexible loading.

The trunk opening of the ID.4 is 3.9 in (+14%) higher than that of the T-Cross. This makes it easier to load taller items (less tilting when pushing in, better headroom when maneuvering large parts).

Conversely, the T-Cross has an advantage in depth from the loading edge to the trunk floor: it is 2.4 in (+60%) "deeper" here. This means more space directly behind the loading edge for taller or stacked cargo on the trunk floor (e.g., several boxes or suitcases placed vertically).

However, for very flat, long items, this advantage does not outweigh the greater overall length of the ID.4.

Other differences are minor and hardly affect practical use: the loading edge of the ID.4 is only 1.2 in (4%) higher, the narrowest trunk width differs by just 0.4 in (1%), and the opening width of the ID.4 is 3.5 in (9%) larger — these values are below the 10% threshold and barely change everyday usability.

Conclusion: For transporting longer or taller items, the ID.4 is clearly advantageous due to the longer cargo space and higher opening.

The T-Cross scores with somewhat more depth directly behind the loading edge, which can be helpful for stacking or many taller boxes, but this does not change the overall shorter length and thus more limited flexibility compared to the ID.4.
