Trunk comparison: Volvo XC40 vs VW ID.4

Comparison of trunk dimensions for the Volvo XC40 and VW ID.4

Key Differences

In the measured dimensions, most deviations between the Volvo XC40 and VW ID.4 are very small (1–3%).

However, notably above the 10% mark is the depth of the trunk (loading edge to trunk floor): the VW ID.4 has a depth +3.9 in greater (+900%) than the Volvo XC40. All other values are close: trunk length with seats folded down +0.4 in (1%), with the first row upright +1.2 in (3%) in favor of the ID.4; the width at the narrowest point is the same, the width of the trunk opening only +0.4 in (1%) in favor of the ID.4. The height of the trunk opening is 2.8 in (10%) greater on the ID.4; the loading edge of the XC40 is 0.4 in higher above the road.

Impact on Usability

The significantly larger depth of the ID.4 means noticeably more usable volume below the loading edge in practice: bulky or taller items can be recessed deeper, allowing more luggage without the loading edge quickly limiting usable height.

This improves loading capacity for bulky but not necessarily very long items and often enables a flatter packing style with better tie-down options.

Everyday consequences:

Transport volume: The ID.4 offers noticeably more space vertically/in depth and thus more usable capacity at the same overall length.
Loading comfort: The ID.4’s loading edge is 0.4 in lower, which is hardly noticeable in practice but slightly reduces lifting effort for heavy items.
Loading height and tall items: The ID.4’s opening is 2.8 in higher, making it easier to load tall goods (threshold: this difference is exactly 10% and should be noted, but is not highlighted as >10%).
Everyday use: For typical shopping or luggage, differences remain marginal; those who frequently transport larger or bulky loads benefit noticeably from the ID.4.

Conclusion: Apart from a significantly deeper trunk floor in the VW ID.4, practical differences are minor. Those needing maximum usable loading height and volume in the trunk recess are better served by the ID.4; for most everyday cases, both models are comparable.
