Trunk comparison: Kia Sportage vs VW ID.4

Key Differences

The trunk length with folded seats is the same for both models; with the first row upright, the VW ID.4 is 1.6 in (≈4%) longer. The width at the narrowest point is 1.2 in (≈3%) greater in the Kia, while the opening width is 0.8 in (≈2%) larger in the VW.

The loading edge of the VW is 0.8 in (≈3%) higher above the ground, and the opening height of the VW is 2.8 in (≈10%) greater than that of the Kia.

The most significant difference is the trunk depth (loading edge to trunk floor): the VW ID.4 is 3.9 in (≈900%) deeper here.

Impact on Usability

The much greater depth value in the VW practically means a significantly deeper loading opening to the trunk floor. This creates more usable volume vertically and makes it easier to store taller or bulkier items without folding down the rear seats.

At the same time, a deeper floor level can make lifting heavy items somewhat more difficult because they must be lifted over the loading edge.

The slightly greater opening height of the VW (2.8 in) additionally supports loading tall items, even though this difference is exactly 10%. The 1.6 in longer loading surface with the first row upright makes the VW slightly more advantageous for long items.

The Kia scores with a bit more width at the narrowest point (+1.2 in), which can help when transporting very wide items. The slightly lower loading edge in the Kia makes lifting heavy loads somewhat easier.

Conclusion: For vertical volume and accommodating taller items, the VW ID.4 is clearly more advantageous (the large depth difference is decisive here). For very wide loads or somewhat easier lifting of heavy items, the Kia offers slight advantages.
