Trunk comparison: Seat Tarraco vs Volvo V90

Key Differences
The most noticeable differences are in vertical space and loading height: The SEAT Tarraco has a trunk opening that is 5.1 in (19%) higher, a depth from loading edge to trunk floor that is 2.4 in (500%) greater, and a loading edge that is 5.5 in (23%) higher above the road compared to the Volvo V90. All other deviations (length with seats folded +4%, width at the narrowest point +4%, opening width +1%) are minor and have only marginal effects.
Impact on Usability
These differences lead to clear practical consequences: The taller opening height of the Tarraco makes it easier to load tall items (e.g., boxes, large suitcases, or bulky furniture pieces loaded upright).
The greater depth of the Tarraco offers more vertical storage space and can prevent luggage from protruding over the loading edge or shifting.
At the same time, the significantly higher loading edge of the Tarraco makes lifting heavy loads more strenuous: crates or tires must be lifted higher, which makes loading and unloading heavy cargo regularly less comfortable.
Here, the Volvo V90 scores with its lower loading edge — easier loading of heavy items and better access for rolling suitcases or strollers.
The slightly greater width of the Volvo at the narrowest point and the marginally longer dimensions with folded seats provide a small advantage when transporting very wide or very long items, but are usually secondary in everyday use compared to the mentioned differences in height and loading edge.
In short: Tarraco offers more vertical interior space and depth (better for tall or discreetly stowed cargo), Volvo V90 offers more comfortable, physically less demanding loading and a slightly wider, more practical layout for very wide items.
