Trunk comparison: Seat Tarraco vs Skoda Octavia Wagon

Key Differences
The Skoda Octavia Wagon has a significantly greater trunk depth: +1.6 in (≈+67%) compared to the SEAT Tarraco. Practically, this means more usable interior height/volume in the cargo area and more space for bulky or tall items; additionally, stacking tends to be easier in the Skoda.
The SEAT Tarraco has a higher loading lip: +4.3 in (≈+17%) above the road, which makes lifting heavy items more difficult and frequent loading and unloading less comfortable.
However, the width of the trunk opening in the SEAT Tarraco is +4.7 in (≈+12%) larger than in the Octavia — this facilitates loading wider items and makes adjusting larger parts easier.
Other, Smaller Differences
Smaller differences have limited practical impact: the Tarraco is minimally longer when fully loaded with seats folded (+0.4 in / 1%) and slightly longer with the first row upright (+1.2 in / 3%), the height of the trunk opening is +2 in (6%) higher in the Tarraco, and the narrowest width is only +0.4 in (1%) larger.
These values only marginally affect everyday usability.
Practical Conclusion
For users who frequently load heavy or tall cargo and rely on a low loading lip and deep cargo floor (e.g., furniture, stacking boxes), the Skoda Octavia Wagon is the more practical choice.
Those who regularly transport wide items or need a larger opening width (e.g., wide sports or leisure equipment) benefit from the SEAT Tarraco. For normal, mixed use cases, the differences in length and interior width are negligible.
