Trunk comparison: Opel Corsa vs Skoda Elroq

Key Differences
Loading floor length with seats folded down: The Škoda Elroq offers +13.8 in (+27%) more interior length than the Opel Corsa. This is a clear advantage for long loads.
Loading floor length with front seats upright: With the front seats upright, the Elroq has +5.5 in (+21%) more cargo lengthwise than the Corsa.
Width of the trunk opening: The Elroq's opening is +6.7 in (+20%) wider than the Corsa's, making it easier to fit wider items through.
Depth of the trunk (loading edge to trunk floor): The Opel Corsa has a significantly larger value here: +6.7 in (+1700%) compared to the Elroq. This means a much deeper recess between the loading edge and trunk floor in the Corsa.
Impact on Usability
The longer length dimensions of the Škoda Elroq (both with folded seats and with upright front seats) make it more practical for transporting long items such as furniture, slats, skis, or roll containers.
Especially when the rear seat is not fully folded down or cannot be, the Elroq offers noticeably more usable length.
The Elroq's 20% wider trunk opening significantly facilitates loading wider or bulky items: doors and tailgates need to be tilted less, and bulky boxes or furniture can be more easily aligned and pushed through.
The significantly greater depth value in the Opel Corsa (the recess between loading edge and trunk floor) increases its usable depth below the loading edge.
Practically, this means items lie deeper in the vehicle, which can result in a lower center of gravity when stacking and is advantageous for short, tall cargo heights. However, the additional recess can make lifting heavy items over the loading edge somewhat more cumbersome.
Smaller differences such as the Elroq's trunk opening being 1.2 in higher, the Corsa's loading edge being 0.4 in higher, or the Elroq's narrowest point being 1.6 in wider are noticeable in everyday use but not decisive for basic usability.
Conclusion
For users who often transport long or wide items, the Škoda Elroq is the more practical choice due to its longer cargo areas and wider opening.
The Opel Corsa, on the other hand, offers a lower loading floor, which can provide advantages in certain packing scenarios (lower stacking height, more secure storage in the recess).
