Trunk comparison: Hyundai IONIQ vs Kia Sportage

Key Differences

The measurable differences focus on the trunk opening and interior depth: The Kia Sportage has a trunk opening that is +2.8 in (≈11%) higher and a trunk opening width that is +4.3 in (≈12%) larger than the Hyundai IONIQ.

Conversely, the depth of the trunk (loading edge to trunk floor) in the Hyundai IONIQ is +4.7 in (≈1100%) greater than in the Kia Sportage. All other specified values (lengths with folded seats, width at the narrowest point, loading edge height) differ only slightly (under ~10%) and are less relevant in practice.

Impact on Usability

For bulky, wide, or tall items, the Kia Sportage is more advantageous: the higher and significantly wider opening makes loading and unloading large boxes, furniture parts, or bulky goods easier because larger cross-sections fit through the opening more easily.

Bringing in bulky parts with a cart or dolly is also simpler due to the wider opening.

The Hyundai IONIQ, on the other hand, offers a significantly greater interior depth, providing a lower loading floor: this means more usable volume below the loading edge, better ability to store luggage "recessed" (lower center of gravity, more concealed storage space), and in many cases a larger total capacity for flat-stacked cargo.

However, the lower opening height and width can make it harder for bulky parts to pass through the opening, even if the interior is deeper. Additionally, the IONIQ's loading edge is slightly elevated, which minimally complicates lifting heavy loads.

Conclusion: Those who frequently transport wide or tall items (e.g., furniture, large boxes) benefit more from the Kia Sportage due to the opening dimensions and ease of loading through.

Those who mainly want to store luggage, boxes, or low-stacked loads and value a lower, more concealed storage space will find the Hyundai IONIQ the more practical solution.
