Trunk comparison: Opel Astra Wagon vs VW Taigo

Key Differences
The Opel Astra Wagon offers significantly more cargo length with the front seats upright: +9.8 in (30%) compared to the VW Taigo. With the seats folded down, the Astra also has more length, but the advantage here is only +3.9 in (6%).
The VW Taigo mainly differs in the vertical arrangement: the depth from the loading edge to the trunk floor is +7.1 in (900%) greater than in the Astra, and the loading edge is +6.3 in (27%) higher above the ground. The height of the trunk opening is slightly higher on the Taigo (+0.8 in / 3%).
Width differences favoring the Astra: at the narrowest point, the trunk is +3.9 in (10%) wider, and the width of the trunk opening is +2.4 in (6%) greater on the Astra than on the Taigo.
Implications for Usability
For long cargo without folding the seats, the Astra is clearly better suited: the 30% advantage in extended cargo length allows longer items in everyday use without seat adjustment. With fully folded seats, the differences are small (only +6% in favor of the Astra).
The Taigo offers more vertical space in the cargo area due to the significantly greater depth (distance from loading edge to trunk floor), which can be helpful when stacking tall items or placing deep boxes.
However, this advantage comes at the cost of a significantly higher loading edge: loading and unloading heavy or bulky items requires more effort because they must be lifted about 6.3 in (27%) higher. The slightly higher opening height (+0.8 in) is hardly relevant in practice.
The greater narrowest width of the Astra (+3.9 in) makes transporting wider items easier; likewise, the slightly wider opening (+2.4 in) helps maneuver larger cargo into the trunk.
In summary: For longer or wider cargo and easier loading and unloading, the Opel Astra Wagon is usually more practical in everyday use. The VW Taigo offers more vertical space inside but requires more lifting effort due to the higher loading edge.
