Trunk comparison: Hyundai IONIQ vs Skoda Karoq

Key Differences (>10%)
The Hyundai IONIQ offers a significantly longer cargo space with the rear seats upright: +5.9 in (20%) compared to the Škoda Karoq.
The Škoda Karoq, on the other hand, has a considerably higher trunk opening: +10.2 in (39%), a greater depth from the loading edge to the trunk floor: +1.2 in (25%), and a wider trunk opening: +3.9 in (11%).
Differences below 10% (e.g., IONIQ with +2.8 in with folded seats, narrowest width +0.4 in, loading edge height +2.4 in/9%) exist but are less significant.
Impact on Usability
The length advantage of the IONIQ with the rear seat upright (20%) makes it more practical for longer items that need to lie flat in the vehicle with normal seating (skis, long boxes, bulky suitcases). When the seats are folded down, the length difference of 4% is hardly relevant.
The significantly higher trunk opening of the Karoq (39%) and the wider opening (11%) make it much easier to maneuver large or taller items inside — such as tall boxes, strollers, or bulky furniture parts.
The greater depth from the loading edge to the floor (25%) provides more usable vertical volume and allows better stacking or accommodation of taller cargo inside.
Practically speaking: Those who frequently transport long items and mostly drive with the rear seat upright benefit more from the IONIQ. Those who often load bulky, tall, or heavy cargo or value comfortable loading (wider and higher opening, deeper loading area) are better served by the Karoq.
