Trunk comparison: Opel Grandland vs Seat Tarraco

Key Differences

The data reveals three relevant differences over 10%:

• SEAT Tarraco: Trunk length with seats folded down is 7.1 in (+11%) larger than the Opel Grandland.
• SEAT Tarraco: Trunk length with the first row of seats upright is 9.1 in (+26%) larger than the Opel Grandland.
• Opel Grandland: Depth of the trunk (distance from loading edge → trunk floor) is 3.9 in (+167%) larger than the SEAT Tarraco — the cargo area is significantly deeper.

Smaller or negligible differences: The height of the trunk opening (+0.8 in / 2%) and the width of the opening (+2.8 in / 6%) are slightly advantageous for the Tarraco; the loading edge height above the road (+1.2 in / 4%) is minimally higher on the Grandland. The narrowest trunk width is the same for both models.

Implications for Usability

Long items and luggage with seats upright: Because the Tarraco is significantly longer with the first row upright (+26%), it is better suited for regularly transporting longer items without folding seats — such as skis, long boxes, or furniture parts that can protrude sideways.

Even with seats folded down, the Tarraco offers a noticeable length advantage (+11%).

Depth and cargo volume in the floor area: The significantly larger "depth" value in the Grandland indicates a deeper cargo compartment. This can provide more usable volume in the lower area (advantageous for bulky, lower items or suitcases that fit into a recess).

At the same time, a deeper trunk floor can make lifting during loading more difficult — especially with heavy loads — and increases the likelihood that smaller items may "disappear" in the deep compartment.

Handling during loading: Due to the slightly larger opening width and height of the Tarraco (both under 10% difference), loading very wide items is easier, even though these advantages are technically small.

The loading edge height is similar on both models; the Grandland is minimally higher, which can slightly complicate lifting, but the difference is minor.

Recommendation by Use Case

Choice for frequent long loads with occupied seats: SEAT Tarraco (due to +26% longer cargo space with first row upright).

Choice for deeper cargo compartment and more volume in the floor area (low, bulky items): Opel Grandland (significantly deeper cargo floor, but possibly less ergonomic when lifting).

For mixed requirements, the Tarraco is overall more flexible due to longer interior dimensions; the Grandland scores with specific loading needs that benefit from a deep cargo floor.
