Trunk comparison: Skoda Elroq vs Skoda Superb Wagon

Key Differences
The Skoda Superb Wagon offers significantly more cargo length: with the seats folded down, the trunk is +18.1 in (28%) longer, and with the first row upright, even +10.2 in (33%) longer than the Skoda Elroq.
Furthermore, the trunk depth (loading edge to floor) in the Superb Wagon is considerably larger at +2.8 in (700%).
The loading edge of the Elroq, on the other hand, is +3.9 in (17%) higher above the road than that of the Superb Wagon. Differences in opening height (+2.4 in / 8%) and widths (+1 to +1.2 in / 1–3%) are comparatively minor.
Impact on Usability
The greater cargo length of the Superb Wagon makes it much better suited for long items (e.g., slats, pipes, skis) and for transports requiring the rear seats to be folded down.
Due to the significantly larger trunk depth, bulky or tall items can be placed further back and deeper in the cargo space, which improves load stability.
The 3.9 in higher loading edge of the Elroq means more effort is required to lift heavy items into the trunk; the Superb Wagon is ergonomically more favorable here and facilitates loading and unloading, especially with heavy or larger loads.
Since differences in opening height and widths are small, they play little role when choosing for wide cargo.
Conclusion: Those who frequently transport long or heavy loads clearly benefit from the Superb Wagon. For normal everyday use with occasional shopping, the differences are less relevant.
