Trunk comparison: Seat Tarraco vs VW Tiguan

Key Differences
The Seat Tarraco offers significantly more usable cargo space in areas that improve everyday practicality: with the first row of seats upright, the trunk is 9.4 in (+27%) longer, which can accommodate longer items (e.g., skis, slats, long boxes) without folding the seats down.
Additionally, the Tarraco's trunk opening is 3.5 in (+12%) higher, making it easier to load and unload tall or bulky cargo.
Also notable is the greater trunk depth between the loading edge and the floor: +2 in (+500%) — this results in a deeper cargo well that offers more volume below the loading edge and facilitates stacking or placing taller items.
What Impact Does This Have on Usability?
The longer loading floor with the seats upright makes the Tarraco more practical when passengers need to sit in the rear and long items must be transported simultaneously. The higher opening reduces bumping when loading large boxes and makes sliding in bulky parts easier.
The deeper cargo well increases usable volume and helps conceal luggage under a cover; however, it may slightly change the lifting of very heavy items because they are placed deeper.
Other, Smaller Differences
With the seats folded down, the Tarraco is only slightly larger (+5.9 in / +9%), which is noticeable but below the 10% threshold. The loading edge in the Tarraco is only 0.4 in higher (+1%), which is practically negligible.
The narrowest width of the trunk is the same; the opening width is 2.4 in (+6%) larger in the Tarraco — a small comfort advantage but not decisive.
Conclusion
For users who frequently want to transport longer or taller cargo without constantly folding seats, the Seat Tarraco is the more practical choice.
Those who prefer more compact exterior dimensions and similar width values will find no major disadvantage in the Tiguan — the clear advantages of the Tarraco lie in length (with passengers), opening height, and loading floor depth.
