Trunk comparison: Opel Corsa vs Volvo XC60

Key Differences
The clear advantages of the Volvo lie in the cargo area: with the seats folded down, the trunk of the Volvo XC60 is 18.1 in (35%) longer, and with the first row of seats upright, it is 11.8 in (45%) longer than the Opel Corsa.
Additionally, the Volvo offers a greater width at the narrowest point: +5.9 in (16%), and the trunk opening is 10.2 in (30%) wider than the Corsa. In contrast, the Opel Corsa has a significantly greater depth between the loading edge and the trunk floor: +7.1 in (≈1700%) compared to the Volvo.
Impact on Usability
More length and width in the Volvo XC60 practically means: longer items (e.g., slats, skis, furniture parts) can be transported more easily, often without fully folding down the seats.
The greater width and wider opening make loading and unloading bulky or irregularly shaped items easier and reduce the risk of catching on the sides or opening.
The greater depth in the Opel Corsa (distance loading edge → trunk floor) means the cargo space feels "deeper" — this can create somewhat more vertical storage space below the loading edge, but makes loading and unloading harder because luggage must first be lifted over the loading edge or lifted/lowered.
For heavy, rollable items, this is a disadvantage compared to a flatter load floor.
Smaller differences such as the 0.4 in higher trunk opening and about 0.8 in higher loading edge of the Volvo (each ≈1–3%) are negligible in everyday use and hardly affect usability.
Conclusion
Those who frequently transport long or wide loads are better served by the Volvo XC60 (significantly more length and width).
Those who mostly carry small luggage or value a deep cargo space with more "depth" will find a different space concept in the Opel Corsa but should expect disadvantages when handling heavy or bulky items.
