Trunk comparison: Opel Astra Wagon vs Seat Tarraco
Key Differences
The Seat Tarraco offers a significantly larger cargo space when configured: With all seats folded down, the Tarraco's trunk is 8.3 in (13%) longer than that of the Opel Astra Wagon.
The trunk depth (loading edge to trunk floor) of the Tarraco is also notably greater, being 1.6 in – stated as 200% compared to the Astra higher.
Finally, the Tarraco's loading edge is 6.3 in (27%) higher above the road than the Astra's.
Smaller differences that do not exceed the 10% threshold include a slightly greater trunk opening height (+2 in/6%) and a wider opening width of the Tarraco (+3.9 in/10% exactly), as well as a slightly larger narrowest trunk width in the Astra (+3.1 in/8%).
Impact on Usability
The longer loading surface with folded seats makes the Tarraco significantly more practical for long items (e.g., furniture parts, long roof rack loads during storage) and for larger overall loads during moves or transports.
The greater trunk depth and overall longer loading surface improve flexibility when stacking and positioning bulky cargo.
However, the significantly higher loading edge of the Tarraco (27% higher) has limiting effects: heavy or bulky goods must be lifted higher, loading large items is more strenuous and may require aids or a second person.
At the same time, the higher loading edge can offer advantages in ground clearance on steep curbs or tight parking spaces but reduces convenience when loading.
The slightly wider opening width of the Tarraco facilitates loading wide parts through the rear opening, while the Astra offers a bit more width at the narrowest interior point — this can be relevant when very wide, bulky items need to be placed crosswise in the trunk.
Conclusion: For users who frequently transport long or bulky cargo, the Tarraco is the more practical choice due to its significantly greater loading length and depth.
For users who mainly transport heavy or frequently lifted loads or need to load very wide items crosswise, the Astra can be more advantageous due to the lower loading edge and greater narrowest width.
