Trunk comparison: Hyundai Elantra GT Wagon vs Skoda Superb Wagon

Key Differences
When comparing the cargo variants, three clear differences stand out: The Škoda Superb Wagon offers a significantly longer cargo floor when folded down (+13.8 in / +20%) than the Hyundai i30 Wagon.
The height of the trunk opening is also significantly greater on the Superb (+5.9 in / +22%), providing more vertical space when loading. Additionally, the depth of the trunk (distance from loading edge to trunk floor) is considerably larger on the Superb (+3.1 in / +700%).
Impact on Usability
The longer cargo floor of the Superb (+13.8 in) makes it much better suited for long items such as slats, long furniture parts, or bicycles without disassembly; in the i30, space runs out more quickly for similar items.
The higher trunk opening (+5.9 in) on the Superb makes it easier to load tall or bulky items (crates, boxes, cartons) because more clearance height is available.
The greater trunk depth on the Superb means cargo can be pushed further forward, increasing usable storage space at the same exterior length — this improves stackability and usable volume.
Additionally, the loading edge height has an effect: The loading edge of the Hyundai i30 is +1.2 in higher above the ground than on the Superb. This makes lifting heavy items into the i30 somewhat less comfortable; loading and unloading is more ergonomic with the Superb.
Smaller differences under 10% (e.g., the slightly greater narrowest width on the i30 +0.4 in or the wider trunk opening on the Superb +3.1 in) have only minor practical impact.
Conclusion
For users who frequently transport long, tall, or bulky cargo (craftsmen, sports equipment, moves), the Škoda Superb Wagon is the more practical choice due to its significantly greater length, opening height, and depth.
The Hyundai i30 Wagon remains a compact, everyday-suitable alternative; its small advantages (slightly more narrow width) are subordinate compared to the clear space advantages of the Superb.
