Trunk comparison: Audi A4 Avant vs Skoda Elroq

Key Differences
The Audi A4 Avant offers significantly more usable space in several areas than the Škoda Elroq.
Particularly notable are: with the front seats upright, the Audi's trunk is 9.8 in (+31%) longer, the height of the trunk opening is 3.5 in (+12%) larger on the Audi, and the depth of the trunk (distance from loading edge to trunk floor) is 1.6 in (+400%) greater on the Audi.
Smaller differences: with the seats fully folded down, the Audi is 6.3 in (10%) longer, the Elroq's loading edge is 2.4 in (10%) higher above the ground, and width and opening width differ by only 0.4 in (≈1%), in favor of the Elroq.
Impact on Usability
The 31% longer usable length with the front seats upright makes the Audi more practical for long items (e.g., boards, skis, furniture parts) without having to adjust the front seats.
The higher trunk opening on the Audi (+3.5 in) makes it easier to load tall or bulky items and reduces the risk of hitting when loading and unloading.
The greater trunk depth (+1.6 in) means more vertical usable space below the loading edge — useful for bulky and lower-lying cargo, but may require slight bending when accessing.
The Škoda Elroq only scores marginally in loading opening width and at the narrowest point (+0.4 in) — which is hardly noticeable in practice. The higher loading edge of the Elroq (+2.4 in) makes lifting heavy items somewhat more strenuous than in the Audi.
Overall, for frequent transport of long or tall items, the Audi A4 Avant is noticeably better suited; for normal everyday cargo, both models are similarly practical.
