Trunk comparison: VW ID.4 vs VW T-Roc

Key Differences

In terms of cargo space, the VW ID.4 offers significantly more length: with the seats folded down, the trunk of the ID.4 is +8.3 in (14%) longer, and with the first row of seats upright, it is even +6.3 in (21%) longer compared to the T‑Roc.

Conversely, the T‑Roc has a considerably greater distance from the loading edge to the trunk floor: this value is +4.7 in (120%) higher in the T‑Roc than in the ID.4.

Impact on Usability

The longer loading surface of the ID.4 makes it more practical for longer or flat-lying items (e.g., slats, furniture parts, long boxes, or skis). Those who regularly transport long loads or frequently carry larger, crosswise items benefit from the ID.4.

The greater distance from the loading edge to the floor in the T‑Roc (deeper trunk well) increases vertical usability and containment of the cargo space: small or stackable items sit more securely and are less likely to fall out.

This can be advantageous in everyday use for groceries, crates, or difficult-to-stack loads. At the same time, the deeper trunk well can make placing or removing very heavy items somewhat more cumbersome, as more work is required to lift them into or out of the floor "downwards."

Other, smaller differences: The trunk opening of the T‑Roc is slightly higher (+2.4 in / 8%) and somewhat wider (+2.4 in / 6%) than that of the ID.4, while the width at the narrowest point is identical.

The loading edge height above the road differs only slightly (+1.2 in in favor of the T‑Roc) and is usually negligible in practice.

Conclusion: Those who transport longer, flat-load items are better served by the ID.4. Those who prefer more vertical depth, better cargo security, and a "deeper" trunk well for crates and shopping bags will find advantages in the T‑Roc.
