Trunk comparison: Hyundai IONIQ vs Opel Corsa

Key Differences
The Hyundai IONIQ offers 12.2 in (23%) more cargo length with the seats folded down and 9.8 in (38%) more cargo length with the front seats upright, compared to the Opel Corsa.
The Opel Corsa, on the other hand, has a trunk opening that is 2.8 in (11%) higher and a cargo area that is 2.4 in (50%) deeper (distance from loading edge to trunk floor) than the IONIQ.
Impact on Usability
Length advantage with the IONIQ: The significantly greater usable length both with folded seats and with the front row upright makes the IONIQ more versatile for long items (e.g., bed slats, long boxes, skis) and increases the overall capacity for bulky, elongated cargo.
This is practical for moving, tradespeople, or anyone who regularly transports long goods.
Height and depth with the Corsa: The higher trunk opening and significantly deeper cargo area make it easier to load tall or bulky items, as more vertical space is available and luggage can slide further into the vehicle.
This can simplify storing large suitcases, boxes, or bulky household appliances. A deeper cargo area can also position the load lower and thus more stably.
Additional points: The loading edge of the IONIQ is slightly higher (+1.6 in, 6%) — this slightly increases the effort required to lift items into the vehicle. Width differences (narrowest width +1.6 in and opening width +3.1 in in favor of the IONIQ) are under 10% and therefore less decisive in practice.
In summary: Those who need to carry longer items and maximum cargo length are better served by the Hyundai IONIQ. Those who more frequently load tall or bulky items with good vertical accessibility benefit more from the Opel Corsa.
