Trunk comparison: Opel Corsa vs VW Tiguan Allspace

Key Differences
The VW Tiguan Allspace offers a 22.8 in (44%) longer loading length with the seats folded down than the Opel Corsa, and with the first row of seats upright, the Tiguan's loading length is even 18.1 in (70%) longer.
In the opposite condition — all seats upright — the Opel Corsa has 7.5 in (40%) more trunk space than the Tiguan. The depth between the loading edge and the trunk floor is 7.1 in (1700%) greater in the Opel Corsa, and the width of the Tiguan's trunk opening is 11 in (33%) wider than that of the Corsa.
What impact does this have on usability?
The significantly longer loading length in the Tiguan (with folded seats and with the first row upright) clearly makes it superior for long items like furniture boards, skis, or building materials; with the rear seats folded down, much more length can be utilized.
The wider trunk opening of the Tiguan simplifies loading wider items or bulky boxes.
The Opel Corsa, on the other hand, scores in everyday use with the larger volume when the interior is fully occupied (all seats upright): more cargo space for passengers compared to the Tiguan.
Additionally, the measured greater depth between the loading edge and the trunk floor in the Corsa is a practical advantage for stacking suitcases or taller items behind the loading edge — creating more usable vertical space or a deeper cargo floor immediately behind the opening.
Other, smaller differences affect handling: The Tiguan's loading edge is 2.8 in higher above the road (10%), which makes lifting heavy loads significantly more strenuous; however, this 10% is not counted among the strongest differences.
The trunk opening height (Opel +0.4 in) and the narrowest width (Tiguan +1.6 in) are minor deviations that have little practical effect.
Conclusion: For long or wide loads, the VW Tiguan Allspace is the more practical choice. For everyday use with passengers and for utilizing a deeper cargo floor behind the loading edge, the Opel Corsa is more advantageous.
