Trunk comparison: Opel Astra Wagon vs VW ID.4

Key Differences

The Opel Astra wagon offers a significantly longer cargo space with the rear seats upright: +5.1 in (≈14%) compared to the VW ID.4. The VW ID.4 stands out with a notably greater installation depth between the loading edge and the trunk floor: +3.1 in (≈400%).

Also noteworthy is the higher loading edge of the VW ID.4: +5.9 in (≈25%) above the road surface.

Impact on Usability

The longer loading floor of the Astra with the rear seats upright makes it more practical for everyday use when frequently transporting long items without folding the seats down (e.g., skis, long boxes, or slats). The gain of about 14% in length increases flexibility for families and tradespeople in daily life.

The significantly larger distance between the loading edge and trunk floor in the ID.4 means more interior depth: items can be placed deeper or stacked higher, which improves the sense of volume and usable height in the cargo area.

However, combined with the approximately 5.9 in higher loading edge compared to the Astra, this results in a practical disadvantage when loading and unloading heavy loads: lifting over the higher threshold requires more effort or aids (e.g., ramps), even though the interior itself offers more depth.

In short: The Astra is better suited for daily practical use with longer loads without folding seats and for easier loading and unloading due to the lower loading edge. The ID.4 offers more internal cargo depth but is less comfortable when handling heavy or bulky items because of the higher loading edge.
