Trunk comparison: Hyundai IONIQ vs Peugeot 5008

Key Differences (highlighted: >10%)
The Peugeot 5008 offers a trunk that is 9.8 in (15%) longer with the seats folded down than the Hyundai IONIQ. Even with the first row of seats upright, the 5008's trunk is 5.5 in (15%) longer. In contrast, the Hyundai IONIQ has a trunk that is 22.4 in (168%) longer with all seats upright than the Peugeot.
The trunk opening of the Peugeot is 5.5 in (21%) higher than that of the IONIQ. Additionally, the width at the narrowest point in the Peugeot is 5.9 in (15%) greater and the width of the trunk opening is 7.5 in (20%) larger than in the Hyundai.
The depth of the trunk (loading edge → trunk floor) of the Hyundai IONIQ is 4.3 in (1100%) greater than that of the Peugeot.
A smaller, non-highlighted difference: the loading edge of the Hyundai is 2 in (7%) higher above the road than that of the Peugeot.
Impact on Usability
Peugeot 5008 – Advantage for bulky, wide, or tall loads: The greater opening height and significantly wider dimensions (both at the narrowest point and at the opening) make it easier to load wide or tall items.
When seats are folded down or the first row is upright, the 5008 offers more cargo length and thus better flexibility for long items with folded seats as well as more cargo space during normal use with the first row upright.
Hyundai IONIQ – Advantage when seats are in use and for securing smaller items: With significantly more length when all seats are upright, the IONIQ is better suited for regularly transporting long items without folding seats.
The greater depth (deeper trunk floor behind the loading edge) allows for deeper storage of luggage or items that should be securely recessed in the trunk; this can provide secure support for loose cargo but makes overcoming the loading edge more difficult with very heavy or bulky items.
In summary: For frequent loading of wide or tall objects and flexible space use after folding seats, the Peugeot 5008 is more practical.
For more cargo length with occupied seats and for a deep trunk that securely holds smaller items, the Hyundai IONIQ is better suited. The slightly higher loading edge of the IONIQ (≈2 in) is a minor disadvantage when lifting heavy loads.
