Trunk comparison: Audi Q7 vs Seat Tarraco

Key Differences (Brief)
The two most noticeable differences are in the trunk opening and the trunk "depth" (loading edge → trunk floor): The SEAT Tarraco has a trunk opening that is 3.1 in or 11% higher than the Audi Q7. Additionally, the depth from the loading edge to the trunk floor in the Tarraco is 2.4 in or 500% greater (reported as significantly larger than in the Q7).
Other differences exist but are smaller than 10%: the Audi Q7 offers about +6.3 in (9%) more length with the seats folded down and +2.8 in (6%) more with the first row upright; furthermore, the narrowest width in the Q7 is +2.8 in (7%) greater and the opening width is +2.4 in (5%) larger.
The loading edge of the Q7, however, sits only +1.2 in (4%) higher above the road.
Impact on Usability
Higher trunk opening in the Tarraco (≈+11%): The larger opening makes it easier to lift and slide bulky or tall items (e.g., plants, boxes, rolling suitcases) inside. For users who frequently load tall cargo, this reduces the risk of hitting the roof edge and simplifies handling.
Significantly greater depth from loading edge to trunk floor in the Tarraco (reported: +2.4 in / 500%): This large relative difference indicates a much deeper trunk floor below the loading edge. Practically, this means that with a fully loaded vehicle, the cargo sits lower and there is a larger step when loading.
Advantage: more usable interior height in the trunk below the opening; disadvantage: heavier items must be lifted more steeply or over the step. Depending on the type of luggage (flat, long items vs. bulky, tall items), this affects usability differently.
For lengthwise or wide cargo, the Audi Q7 scores despite lacking >10% advantages: it offers more usable loading length (with seats folded +6.3 in or 9%) and a few centimeters more at the narrowest point and opening width, which facilitates loading wider items.
The slightly higher loading edge of the Q7 (+1.2 in) can make lifting in slightly more difficult but will usually be less noticeable in everyday use than the larger differences found in the Tarraco.
Conclusion: Those who often need to load tall items or require a lot of vertical space benefit from the SEAT Tarraco (higher opening, greater depth).
Those who need more length and width in the cargo area (long or wide items) are better served by the Audi Q7. Smaller differences in loading edge height and length values only moderately affect everyday practicality.
