Trunk comparison: Jeep Avenger Electric vs Skoda Superb Wagon

Key Differences
The Škoda Superb Wagon offers significantly more usable cargo space: with the seats folded down, the trunk of the Škoda is +31.1 in (59%) longer, and with the first row of seats upright, it is +15.4 in (58%) longer than the Jeep Avenger Electric. At the narrowest point, the Škoda is +4.3 in (12%) wider.
The Jeep features a larger trunk "well": the depth from the loading edge to the trunk floor is +1.2 in (38%) greater in the Jeep, but at the same time, the loading edge of the Jeep sits +5.1 in (22%) higher above the road.
Smaller differences (height of the trunk opening +1.2 in / 4%, width of the opening +2.8 in / 7%) are comparatively insignificant.
Impact on Usability
The large length differences in favor of the Škoda mean practically: longer items (e.g., furniture parts, skis, long boxes) can be transported much more easily, even without fully folding down the seats.
Even with full seating occupancy, the Škoda retains significantly more usable cargo space, making it much more practical for families, moves, or tradespeople's trips.
The Škoda's greater narrow width facilitates loading wider or bulky items because less turning or tilting is required.
The Jeep's larger depth dimension does provide somewhat more "vertical volume" in the trunk (better stacking, deeper-lying cargo), but in practice, this is limited by the significantly higher loading edge: despite the deeper well, the Jeep's trunk floor still sits higher above the road (effectively about 3.9 in higher), making lifting heavy loads into the Jeep more strenuous.
Conclusion: For transport tasks involving long or wide items and for maximum practical cargo space, the Škoda Superb Wagon is clearly advantageous. The Jeep Avenger offers more vertical capacity due to the deeper trunk floor but is less loading-friendly for heavy and bulky items because of the higher loading edge.
