Trunk comparison: Kia Sportage vs Opel Astra Wagon

Key Differences (Highlight >10%)

The Opel Astra Wagon offers a significantly larger cargo space with the first row of seats upright: +6.7 in (≈19%) more length than the Kia Sportage. Additionally, the depth of the trunk (measured from the loading edge to the trunk floor) is +0.8 in (100%) greater in the Opel.

In contrast, the loading edge of the Kia Sportage sits significantly higher: +5.1 in (≈22%) above the road compared to the Astra.

All other measured differences are much smaller (e.g., trunk length with folded seats +1.2 in/2%, opening height +2 in/7%, narrowest width +2 in/5%, trunk opening width equal) and are not highlighted here.

Impact on Usability

Because the Opel offers about 19% longer cargo space and greater depth with the rear seat upright, it is more practical for everyday use when passengers frequently sit in the back and longer or bulky items (e.g., skis, long plants, craft materials) need to be transported simultaneously.

The greater depth also means more usable floor area, allowing smaller stacks or boxes to stand more stably.

The higher loading edge of the Kia makes loading and unloading heavier items more strenuous, as more lifting is required. This can be noticeable when regularly transporting shopping crates, luggage, or bulky items.

On the other hand, a higher loading edge in SUV-like vehicles can indicate better ground clearance, which can be advantageous when driving on rougher roads.

In short: For maximum usable length with an occupied rear seat and a deeper, more stable cargo floor, the Opel Astra Wagon is better suited.

For users who prioritize off-road capability or higher ground clearance, and who lift heavy loads less frequently, the Kia Sportage can still be attractive despite the higher loading edge.
