Trunk comparison: Seat Tarraco vs Tesla Model Y

Key Differences
The SEAT Tarraco offers noticeably more space and better accessibility in several areas: the height of the trunk opening is +5.5 in (20%) higher than the Tesla Model Y, the width of the trunk opening is +5.5 in (14%) larger, and the depth of the trunk (loading edge to trunk floor) is +2.4 in (500%) higher.
These three differences over 10% are the most relevant and primarily determine which goods can be loaded more easily.
Impact on Usability
The higher trunk opening makes it easier to load and unload taller or bulky items (e.g., large suitcases, plants, or furniture parts) without side edge maneuvers.
The wider opening significantly facilitates loading wider cargo. The greater depth from the loading area to the floor means more usable space in depth/volume, allowing longer or bulkier items to lie deeper and more securely.
Smaller differences also affect practical use but less strongly: The Tarraco's loading edge is +2 in (7%) higher above the road, making lifting heavy items somewhat more strenuous; the narrowest trunk width is only +2.4 in (6%) larger—a small advantage when fitting narrow items.
The Tesla Model Y has a +2.8 in (4%) longer loading floor with folded seats, which can be useful for very flat, long loads (e.g., long slats or boards). With the first row of seats upright, the +0.4 in (1%) difference is negligible.
Conclusion: For regularly transporting tall, wide, or bulky items, the SEAT Tarraco is more advantageous. If primarily very long, flat items are transported or if a lower loading edge for easier lifting is more important, the Tesla Model Y has practical advantages.
