Trunk comparison: VW ID.4 vs VW Touran

Main Differences (≥10%)

The VW ID.4 offers a trunk that is 23.6 in (176%) longer with the rear seats upright than the Touran. The trunk depth (loading edge to trunk floor) is 3.5 in (900%) greater in the ID.4. Additionally, the loading edge of the ID.4 is 4.7 in (19%) higher above the ground than that of the Touran.

Implications for Usability

The significantly greater usable length with seats upright makes the ID.4 more practical when passengers need to remain seated and long items (e.g., poles, skis, long boxes) still need to be transported.

The greater trunk depth means more volume below the loading edge; this increases cargo capacity but makes loading heavy items more cumbersome because they must be lowered or lifted further.

The higher loading edge of the ID.4 amplifies this effect: more effort or a higher lifting/pushing motion is required when loading and unloading heavy loads compared to the Touran.

Other, Smaller Differences

The Touran has a trunk that is 3.9 in (6%) longer with the seats folded down and 2.8 in (7%) longer with the first row of seats upright—both minor differences. The trunk opening of the Touran is about 2.4 in (8%) higher than that of the ID.4, which can slightly ease loading tall items.

The narrowest trunk width is 1.6 in (4%) larger in the Touran, while the opening width of the ID.4 is 1.2 in (3%) larger—both differences are marginal for most practical situations.

Conclusion

For users who want to transport longer or bulky items with a full passenger load and value maximum interior volume, the ID.4 is advantageous.

For frequent loading and unloading of heavy loads or when a lower loading edge is preferred (easier handling), the Touran is more practical. Minor width and opening advantages usually do not affect the decision.
