Trunk comparison: Opel Grandland vs VW ID.4

Most Important Difference

The depth of the trunk (loading edge to trunk floor) is 2.4 in (+60%) greater in the Opel Grandland than in the VW ID.4. This is the only difference with more than 10% deviation and thus the most noticeable practical advantage of one vehicle over the other.

Other Differences (less than 10%)

When all seats are folded down, the cargo length of both models is the same. With the first row of seats upright, the trunk of the VW ID.4 is 2 in (about 6%) longer than that of the Opel Grandland.

The height of the trunk opening of the Opel Grandland is 0.4 in (1%) higher than that of the ID.4. The loading edge of the Opel Grandland is 1.6 in (5%) higher above the ground than that of the ID.4. The width at the narrowest point is the same for both, and the width of the trunk opening of the Opel is 0.4 in (1%) larger.

Impact on Usability

The significantly greater depth in the Opel means more usable storage space in the recess below the loading edge: items can be recessed deeper, which provides more space when transporting bulky or irregularly shaped goods and can potentially increase the visible cargo volume.

This is especially helpful when storing boxes or bags that protrude less in a deeper recess.

On the other hand, the Opel has a slightly higher loading edge (+1.6 in), making lifting heavy items somewhat more strenuous than in the ID.4 with its lower loading edge.

The slightly greater usable length in the ID.4 with the rear seat upright (+2 in) makes it marginally better for longer items without folded seats. Differences in opening height and width of about 0.4 in each are practically negligible, as is the identical width at the narrowest point.

In summary: For users who frequently recess bulky items deep in the trunk or need the advantages of a deeper loading floor, the Opel Grandland is advantageous. Those who often load and unload heavy items or need a bit more length with the rear seat upright have a slight advantage with the VW ID.4.
