Trunk comparison: Audi A4 Avant vs Skoda Karoq

Key Differences
The comparison reveals three notable differences: The Audi A4 Avant offers a cargo space length that is 10.6 in (17%) longer with the seats folded down and a cargo space length that is 11.4 in (38%) longer with the first row upright than the Škoda Karoq.
In contrast, the Škoda Karoq has a depth between the loading edge and trunk floor that is 3.9 in (200%) greater than the A4 Avant. Other deviations (trunk opening height +2.8 in, loading edge height +2 in, width ±0.8 in) are less than 10% and therefore less significant.
Impact on Usability
The longer loading length of the A4 Avant makes it significantly more practical for long items such as slats, skis, or furniture boards: even with the rear seats upright, more usable length remains, and with the seats folded down, considerably longer loads can be accommodated.
The Karoq scores with its significantly greater depth between the loading edge and trunk floor: this facilitates storing tall or bulky items that need to be placed close to the floor and creates more vertical storage space.
The smaller differences (higher trunk opening and higher loading edge in the Karoq) mean in practice: the Karoq can be loaded slightly better for very tall items, but the somewhat higher loading edge increases the effort required to lift heavy loads inside.
Width differences are negligible and hardly affect everyday usability.
