Trunk comparison: BMW i4 vs Skoda Superb Wagon

Key Message
The Škoda Superb Wagon is overall more favorable in cargo space: it offers significantly more length with the seats folded down as well as a larger and wider trunk opening. The BMW i4, on the other hand, has a higher loading lip and a slightly deeper cargo area between the loading lip and trunk floor.
Notable Differences (percentage >10%)
- Length with seats folded down: Škoda +14.6 in (21%) — longer than BMW i4.
- Height of trunk opening: Škoda +5.9 in (22%) — the opening is significantly higher/taller in terms of greater vertical clearance.
- Width at the narrowest point: Škoda +5.1 in (15%) — more usable interior width in the wagon.
- Width of trunk opening: Škoda +4.7 in (13%) — easier loading of wider items.
- Depth (loading lip → trunk floor): BMW i4 +0.8 in (25%) — the i4 has a slightly deeper cargo area (small absolute value, large percentage).
- Loading lip height above ground: BMW i4 +4.3 in (19%) — the i4’s loading lip is significantly higher off the ground.
Impact on Usability
- Longer loading surface with folded seats (Škoda) means: longer items (e.g., slats, long boxes, skis, furniture parts) can be loaded more easily and often completely. For users who regularly transport long cargo, the Superb Wagon is clearly more practical.
- Greater height and width of the trunk opening as well as larger interior width (Škoda) lead to easier loading and unloading of bulky or voluminous items (e.g., crates, strollers, bicycle accessories). Wider opening and more interior width reduce the risk of catching on the sides or frame.
- The higher loading lip of the BMW i4 (+4.3 in) makes lifting heavy items in and out more difficult; this makes loading and unloading more strenuous, especially with heavy cargo or frequent use. Conversely, a lower loading lip (Škoda) can ease handling.
- The slightly deeper cargo area of the BMW i4 (+0.8 in) creates a marginally larger "well" under the loading lip, allowing small items to lie more stably and providing slightly more usable depth. However, the absolute difference is small; the practical advantage is limited.
- With normal use and the first row of seats upright, the difference in trunk length is small (Škoda +3.1 in / 8%) and hardly noticeable in everyday life; relevant advantages mainly appear with fully folded seats or when transporting bulky cargo.
Conclusion
For regular transport of long, wide, or tall items, the Škoda Superb Wagon is the more practical choice due to longer loading surface with folded seats and significantly larger opening/width. The BMW i4 offers a slightly deeper cargo area but has a significantly higher loading lip, which complicates loading and unloading — therefore it is less suitable for heavy or bulky cargo.
