Trunk comparison: Audi Q5 vs Skoda Superb Wagon

Key Differences
The Škoda Superb Wagon offers a significantly longer cargo space with the seats folded down: +18.5 in (28%) compared to the Audi Q5. Even with the front seats upright, the trunk floor of the Superb is longer by +4.3 in (12%).
The loading edge of the Audi Q5, on the other hand, is higher: +5.9 in (25%) above the ground than that of the Superb.
Smaller differences under 10% include: the height of the Superb's trunk opening is +1.2 in (4%) higher, the depth (loading edge to trunk floor) is the same, the narrowest width of the trunk is +0.8 in (2%) greater in the Audi, and the width of the trunk opening in the Audi is +2.8 in (7%) wider.
Impact on Usability
Due to the significantly greater loading length with the seats folded down, the Škoda Superb Wagon is much better suited for long items (e.g., slats, furniture parts, skis, long packages) and for users who regularly transport long or bulky loads.
Even with the front seats upright, the Superb offers noticeably more usable cargo space for suitcases and everyday transport.
The lower loading edge of the Superb makes lifting heavy items into the trunk significantly easier—less effort and better handling when loading.
The Audi Q5's loading edge, being 5.9 in higher, requires more lifting effort; this can be noticeably disadvantageous when frequently transporting heavy loads or during regular loading and unloading.
The slightly greater width at the narrowest point and the wider trunk opening of the Audi (both in the single-digit percentage range) can minimally ease loading very wide items but are only marginal advantages compared to the differences in length and loading edge height.
The identical depth of the trunk means both vehicles are equal in floor area (loading edge to trunk floor).
Conclusion: If longer loads and easier loading in everyday use are important, the Škoda Superb Wagon is the more practical choice. The Audi Q5 offers slightly more width at critical points but does not compensate for tasks that benefit from longer cargo space and a lower loading edge.
