Trunk comparison: VW Golf Wagon (Mk5) vs VW ID.3

Key Differences (only values >10% highlighted)

The VW Golf 5 offers a +6.7 in (≈11%) longer cargo floor length with folded seats than the VW ID.3 and even a +10.2 in (≈33%) longer usable length with the first row of seats upright.

The VW ID.3 has a significantly greater depth from the loading edge to the trunk floor: +4.3 in (≈220%). Additionally, the loading edge of the ID.3 sits +5.1 in (≈20%) higher above the road than the Golf.

What impact do these differences have on usability?

Length: The greater usable length of the Golf (especially +33% with the first row upright) makes it clearly better suited for long items like boards, skis, or long boxes. If you often need to transport bulky or long cargo, the Golf offers noticeably more versatility.

Loading depth and loading edge height: The ID.3 has on one hand a significantly deeper trunk below the loading edge (+4.3 in), but on the other hand the loading edge itself is +5.1 in higher.

Practically, this means the volume or vertical loading area behind the loading edge is larger (good for stackable, bulky cargo), but access is more demanding because items must be lifted higher.

Calculated, this results in the ID.3's trunk floor being only slightly (≈0.8 in) higher above the ground than the Golf (13 − 11 ≈ 0.8 in), but the physical lifting effort when loading remains noticeable due to the higher loading edge.

Width and opening: Differences in trunk opening width and narrowest point are in the single-digit percent range (≤5%) and are hardly relevant in everyday use. However, the slightly larger opening of the Golf (+2 in) makes it marginally easier to load very wide items.

In summary: For transporting long items and easier lifting (lower loading edge), the Golf is more practical. For more usable volume under the loading edge and higher interior volume for stackable cargo, the ID.3 offers advantages, paid for by a higher loading edge and thus somewhat less convenient loading access.
