Trunk comparison: Opel Astra Wagon vs Skoda Karoq

Key Differences
The Opel Astra Sports Tourer offers a cargo length that is 8.7 in (14%) longer with the rear seats folded down compared to the Škoda Karoq. With the rear seat upright, the difference is even more pronounced: the Astra has a cargo length that is 10.2 in (34%) longer.
In contrast, the loading edge of the Škoda Karoq sits 2.8 in (11%) higher above the road than the Astra.
Smaller differences include: the trunk opening of the Karoq is 2.8 in (8%) higher, the depth (loading edge → floor) in the Karoq is 0.4 in (7%) greater, the narrowest width in the Astra is 0.4 in (1%) larger, and the opening width in the Astra is 1.2 in (3%) wider.
Impact on Usability
Due to the significantly greater length of the Astra (14% with folded seats, 34% with upright rear seat), longer items can be transported and more usable cargo length is available in everyday use without or with only partially folded rear seats — practical for skis, long furniture parts, or luggage when fully occupied.
The lower loading edge of the Astra (because the Karoq sits 11% higher) also makes it easier to lift heavy items into the trunk; loading bulky or heavy loads in the Karoq requires more effort.
The Karoq offers slight advantages with a somewhat higher opening and slightly greater interior height/depth when loading tall or bulky items, but these differences are small (<10%) and affect everyday usability less than the length-related differences. Width differences favoring the Astra are minimal and hardly noticeable in practice.
