Trunk comparison: Audi A4 Avant vs Kia Sportage

Key Differences

The Audi A4 Avant offers only a slightly longer cargo area with the seats folded down (+5.5 in / 8%), but with the first row upright, its trunk is significantly longer: +5.9 in (≈17%) compared to the Kia Sportage.

Furthermore, the trunk opening of the A4 is 4.7 in (≈16%) higher, and the measured depth from the loading edge to the trunk floor is 2 in (≈400%) greater than in the Sportage.

On the other hand, the loading edge of the Sportage is 3.5 in (≈14%) higher above the ground. Smaller advantages of the Sportage include a slightly larger minimum trunk width (+5%) and a slightly wider opening (+3%), but these values are below the 10% mark and thus less significant.

Implications for Usability

Because the A4 offers noticeably longer cargo space with the rear seat upright (+17%), it is better suited for longer luggage or furniture that should not be fully folded down.

The higher trunk opening and greater depth between the loading edge and floor also mean that bulky or tall items fit more easily into the interior and are less restricted by the opening height — practical for boxes, suitcases, or bicycles without disassembly.

The lower load floor of the A4 combined with the 3.5 in lower loading edge (compared to the Sportage) reduces the effort required to lift heavy loads inside; the Sportage requires more lifting due to the higher loading edge.

The Kia Sportage, on the other hand, scores with a slightly greater width at the narrowest point and a wider opening. This makes it marginally more advantageous when transporting wide, flat items where width is more important than length or height.

Overall, however, the A4 Avant is the more practical choice for longer or taller cargo and for frequent loading and unloading of heavy goods; the Sportage offers smaller advantages for lateral storage of wide items.
