Trunk comparison: Hyundai Kona vs Tesla Model Y

Key Differences
The Tesla Model Y offers significantly more cargo length: +11 in (17%) with seats folded and +9.8 in (29%) with the first row upright compared to the Hyundai Kona.
The Hyundai Kona has a higher trunk opening: +3.5 in (13%) in height compared to the Tesla Model Y.
The Hyundai Kona has a significantly greater trunk depth (loading edge → trunk floor): +2 in (400%) compared to the Tesla Model Y.
Implications for Usability
The greater cargo length in the Model Y makes it easier to transport longer items (e.g., slats, furniture parts, skis). Those who frequently need to carry long or bulky, flat items clearly benefit from the Tesla.
The Kona, on the other hand, offers more vertical space at the opening and a deeper loading floor. The higher opening facilitates storing tall or bulky items that require height.
The greater depth means cargo can fit further "down" into the trunk — practical for layered packing or when items need to be placed below the loading edge.
Small practical effects: The loading edge of the Model Y sits slightly higher (+0.8 in / 3%), which minimally complicates lifting heavy loads. Width differences (Kona at the narrowest point +3.5 in / 9%, opening width +1.2 in / 3%) are comparatively small and hardly affect everyday usability.
Conclusion
For long, flat transports, the Tesla Model Y is the better choice. For loading tall or deep-stored items, the Hyundai Kona offers advantages due to the higher opening and deeper loading floor. Which option is more practical depends on the typical cargo profile.
