Trunk comparison: Jeep Avenger Electric vs Seat Tarraco

Key Differences (highlighted: >10%)
The SEAT Tarraco offers significantly more cargo length and width: with the seats folded down, the trunk of the Tarraco is +20.9 in (+40%) longer, and with the first row of seats upright, even +17.7 in (+67%) longer compared to the Jeep Avenger Electric.
The narrowest width of the trunk is +4.3 in (+12%) greater in the Tarraco, and the width of the trunk opening is +6.3 in (+16%) wider than that of the Jeep. In contrast, the Jeep Avenger Electric has a significantly greater depth (loading edge to trunk floor) by +2 in (+83%) compared to the Tarraco.
Smaller differences: The trunk opening of the Tarraco is only slightly higher (+1.6 in / 5%) and the loading edge of the Tarraco is marginally higher above the ground (+1.2 in / 4%) — these values have little impact on usability.
Impact on Usability
Space for long and wide items: Due to the significantly greater length and wider opening, the SEAT Tarraco is better suited for long items (boards, skis, furniture parts) and bulky goods. The larger opening width and greater minimum width inside the trunk reduce maneuvering and angling when loading.
Vertical space and handling: The Jeep Avenger Electric offers a deeper cargo floor behind the loading edge due to its significantly greater depth.
This provides more space for taller loads inside and more easily prevents luggage from shifting, but makes reaching in and removing heavy items less practical because the load must be lowered further into the trunk.
In the Tarraco, the slightly higher loading edge requires more lift from the ground to the edge, but the actual trunk floor lies flatter below the loading edge, which simplifies repositioning items inward.
Practical conclusion: Those who often transport long or wide loads (e.g., furniture, building materials, sports equipment) and value easy loading of large parts will find the SEAT Tarraco the more practical solution.
Those who more frequently carry stackable, tall, or bulky loads in a deeper cargo space and can manage somewhat more depth reach (but more difficult access) will find advantages in the Jeep Avenger Electric.
