Trunk comparison: Opel Grandland vs VW ID.3

Key Differences

The Opel Grandland offers a cargo length that is 6.3 in longer (+10%) with the rear seats folded down compared to the VW ID.3. With the front seats upright, the Grandland is significantly longer: +3.9 in (13%).

The width of the trunk opening is 4.7 in (13%) wider in the Grandland, while the depth from the loading edge to the trunk floor is the same in both models.

The height of the trunk opening in the Grandland is 2.4 in (8%) higher than that of the ID.3. The loading edge in the Grandland is only 0.4 in (1%) higher from the road, and the narrowest width is the same in both vehicles.

Implications for Usability

The greater cargo length with folded seats (+6.3 in/10%) makes the Grandland better suited for longer items (e.g., slats, skis, furniture parts).

Even more relevant in everyday use is the longer cargo space with the front seats upright (+3.9 in/13%): this means more usable storage space with a normal number of passengers, so more packing volume for suitcases or shopping trips.

The significantly wider trunk opening (+4.7 in/13%) makes loading and unloading wider objects (e.g., strollers, furniture boards, wide boxes) easier because less maneuvering is needed.

The 2.4 in higher opening slightly improves sliding in tall items but is not a major advantage over the ID.3. Consistent trunk depths and the same narrowest width mean the floor area and tight spots are similarly usable.

The 0.4 in higher loading edge of the Grandland is practically insignificant for loading; heavy items need to be lifted only minimally higher. Overall, the Grandland offers noticeable advantages over the ID.3 especially in usable length (both in everyday use and with folded seats) and in the width of the opening.
