Trunk comparison: Hyundai Elantra GT Wagon vs Seat Leon

Key Differences
The Hyundai i30 wagon offers a trunk that is +11.4 in (19%) longer with the seats folded down and +8.7 in (27%) longer with the first row of seats upright compared to the SEAT Leon.
The narrowest interior width of the trunk is +8.3 in (26%) larger in the Hyundai, while the width of the trunk opening is +4.3 in (11%) larger in the SEAT.
The SEAT Leon has a trunk opening that is +5.1 in (19%) higher and a depth between the loading edge and trunk floor that is +9.8 in (2400%) greater. Additionally, the loading edge of the SEAT Leon is +5.1 in (21%) higher above the ground than that of the Hyundai.
Impact on Usability
Loading length: Due to the significantly greater interior length (Hyundai +11.4 in / +8.7 in), the i30 wagon is better suited for long items such as slats, skis, or long furniture parts — even with the seats upright, more usable centimeters remain.
Interior width vs. opening width: The Hyundai has more space at the narrowest point (+8.3 in), which makes loading wider cargo inside easier.
The SEAT wins in opening width (+4.3 in), which simplifies positioning bulky items at the tailgate, but the narrowest point inside the trunk remains advantageous in the Hyundai for wide goods.
Trunk height and depth: The higher trunk opening (+5.1 in) and significantly greater depth between the loading edge and floor (+9.8 in) in the SEAT suggest more vertical space or a different floor structure — this can help when loading taller items depending on how the floor formation is used.
However, the much greater depth usually means the cargo floor lies further below the loading edge or is more contoured.
Loading edge height: The loading edge, which is +5.1 in higher in the SEAT, makes lifting heavy items steeper and more strenuous; the Hyundai with its lower loading edge is more ergonomic for frequent loading (groceries, strollers, suitcases).
Practical conclusion: For long items and wider loads, the Hyundai i30 wagon is overall more practical. The SEAT Leon offers advantages in opening width and apparently more vertical space/depth structure in the trunk, but its higher loading edge makes frequent lifting of heavy loads less convenient.
