Trunk comparison: Hyundai IONIQ vs Tesla Model Y

Key Differences (>10%)

In the usable length comparison, the Tesla Model Y clearly has the advantage: with the seats folded down, it offers a cargo area that is 12.2 in (19%) longer, and with the front row seats upright, the Model Y's cargo area is 7.9 in (22%) longer than the Hyundai IONIQ's.

In contrast, the IONIQ has a significantly greater trunk depth between the loading edge and the trunk floor: the IONIQ is 4.7 in (1100%) higher here than the Model Y.

What are the practical implications?

The longer cargo length of the Tesla Model Y makes it more practical for long items: furniture parts, long slats, skis, or longer boxes can be transported more easily crosswise or lengthwise — both with folded seats and with the front seats upright.

Those who regularly plan long transports will have fewer restrictions with the Model Y.

The significantly greater trunk depth of the Hyundai IONIQ means more space "in depth" below the loading edge. This is advantageous for securely stacking loose or smaller items so they don't shift during braking, and to better utilize volume (suitcases, shopping bags, toolboxes).

However, a deeper well reduces the practical loading height for very flat, long items and can make handling heavy luggage a bit less comfortable — the loading edge on the IONIQ is also slightly higher, which can make lifting a bit more difficult.

Small differences such as the slightly higher opening height (+1.2 in, Model Y), the wider opening width of the Model Y (+2.8 in), or the slightly greater narrowest width on the IONIQ (+2 in) are under 10% and only moderately affect usability.

In summary: the Model Y scores on length and transporting long parts; the IONIQ offers more storage depth and better protection against shifting. Which variant is more favorable depends on the typical cargo.
