Trunk comparison: Ford S-MAX vs VW ID.3

Key Differences

The Ford S‑Max offers significantly more cargo length: with the seats folded down, the trunk is 17.7 in (≈29%) longer and with the first row of seats upright, 13 in (≈42%) longer than the VW ID.3. The trunk opening of the S‑Max is also 7.1 in (≈24%) higher, which makes loading tall items easier.

In contrast, the VW ID.3 has notably higher dimensions around the loading edge and floor: the depth from the loading edge to the trunk floor is 5.1 in (≈433%) greater and the loading edge itself is 7.9 in (≈35%) higher above the road than in the S‑Max.

Smaller differences, at or below 10%, include the narrowest width (+0.8 in / 2%) and the width of the opening (+3.9 in / 10%), which are negligible.

Impact on Usability

The longer cargo dimensions of the S‑Max mean specifically: longer items (skis, slats, furniture parts) can be transported more easily, and even with full seating, more usable storage space is available. The higher trunk opening simplifies loading tall or bulky objects because more vertical space is available.

In the ID.3, the higher loading edge and greater depth between the loading edge and trunk floor have different effects: lifting heavy items into the trunk requires more effort because the loading edge is significantly higher.

The greater "depth" can allow items to lie deeper in the cargo space but makes loading and unloading less comfortable and limits access to the trunk floor. For very long or tall items, the ID.3 is less suitable due to the shorter length and lower opening height.

Conclusion: Those who frequently transport long or bulky loads or value easy loading and unloading will find the Ford S‑Max the more practical solution.

Those who mainly carry smaller or lighter items and are not bothered by the higher loading edges can manage with the ID.3 — but the mentioned differences in volume and loading height clearly favor the S‑Max in everyday usability.
