Trunk comparison: Ford S-MAX vs VW ID.4

Main Differences

The Ford S‑Max offers a longer trunk with the rear seats folded down: +11.4 in (17%) compared to the VW ID.4, and with the first row of seats upright, the S‑Max's trunk is also +7.1 in (19%) longer.

The height of the S‑Max trunk opening is +5.1 in (16%) higher than that of the ID.4. On the other hand, the VW ID.4 has a significantly greater trunk depth (loading edge to trunk floor): +2.8 in (233%) compared to the S‑Max, and the loading edge of the ID.4 sits overall +6.7 in (30%) higher above the ground.

Smaller differences include the trunk width at the narrowest point (+0.8 in / 2% in favor of the S‑Max) and the width of the trunk opening (+0.4 in / 1% in favor of the ID.4), both of which are negligible.

Impact on Usability

The longer loading options and higher opening of the S‑Max (each >10%) make it more practical for long or tall items and for loading bulky cargo: longer items can be accommodated more easily without folding seats or complicated angles, and the greater opening height simplifies placing tall items upright.

The significantly deeper trunk area in the ID.4 (+2.8 in / 233%) means more volume can be used below the loading edge — advantageous for items that should be stored in the recessed floor or placed lower.

At the same time, the significantly higher loading edge of the ID.4 (+6.7 in / 30%) makes lifting heavy loads in and out more strenuous and reduces convenience during frequent loading (e.g., groceries, strollers), while the lower loading edge of the S‑Max facilitates handling heavy or bulky items.

Small width differences are hardly noticeable and do not significantly affect practical use.
