Trunk comparison: Hyundai IONIQ vs Hyundai Kona

Key Differences (>10%)
Three dimensions stand out clearly: The height of the trunk opening is +4.7 in (≈18%) larger in the Hyundai Kona, the width of the trunk opening is +3.9 in (≈11%) larger in the Kona, and the depth of the trunk (loading edge → trunk floor) is +2.8 in (≈140%) larger in the Hyundai IONIQ.
Impact on Usability
The greater height and width of the trunk opening in the Kona make loading bulky or awkward items easier: tall boxes, furniture parts, or bulky sports equipment can be maneuvered more easily through the opening. Loading wide items is also more practical due to the approximately 3.9 in larger opening clearance.
The significantly greater distance from the loading edge to the trunk floor in the IONIQ means more usable interior height directly behind the loading edge — this creates space for higher stacked or deeply seated cargo in the trunk footwell.
At the same time, this greater depth usually requires more reach when loading and can make lifting heavy items onto the loading edge more difficult because more height must be overcome.
In summary: The Kona is advantageous when it comes to easily fitting large, wide, or tall items through the opening; the IONIQ offers more volume height inside behind the loading edge, which is useful for stacking or transporting taller cargo, but at the cost of somewhat less favorable lifting and reach conditions when loading.
