Trunk comparison: Kia Stonic vs Opel Astra Wagon
Main Differences (only >10% highlighted)
- Cargo length with seats folded down: The Opel Astra Wagon offers +11.4 in (21%) more length than the Kia Stonic.
- Cargo length with front seats upright: The Opel Astra Wagon offers +15 in (55%) more length than the Kia Stonic.
- Trunk depth (loading edge → trunk floor): The Kia Stonic has a significantly deeper cargo well with +6.3 in (800%) compared to the Opel Astra Wagon.
- Loading edge height above the road: The loading edge of the Kia Stonic is +7.1 in (31%) higher than that of the Opel Astra Wagon.
Impact on Usability
- Length and transport of long items: Due to the significantly greater length of the Opel Astra Wagon (both with folded seats and with upright seats), it clearly has an advantage when transporting long items such as slats, pipes, long boxes, or skis.
Those who regularly transport long cargo gain flexibility and comfort with the Astra Wagon.
- Vertical space and loading mode: The Kia Stonic has a significantly deeper cargo well. This allows bulky or higher stacked items to be recessed somewhat "deeper" in the cargo area, which increases vertical volume and enables somewhat more stable securing of lower center of gravity loads.
- Loading and unloading / physical effort: The loading edge of the Kia is significantly higher. This means items must be lifted higher when loading, making loading and unloading heavy loads more strenuous.
The combination of a higher loading edge and deeper cargo well results in the visible interior height appearing larger, but the physical effort to lift over the edge remains higher.
- Overall trunk floor height relative to the road: Calculating loading edge height minus trunk depth results in only a small difference in actual floor height compared to the Astra (about +0.8 in in favor of the Kia in the given values).
Practically, this means: Although Kia has a higher loading edge and a deeper well, the trunk floor in absolute centimeters is almost at the same level as the Opel. Still, handling over the higher edge remains noticeably more demanding for the user.
- Width and opening (under 10%): Smaller differences in trunk width and opening (each <10%) exist but have only marginal practical impact on usability.
Conclusion
For frequent transport of long items, the Opel Astra Wagon is the better choice. Those who prefer more vertical capacity in a deeper cargo well and accept minor inconveniences regarding lifting can benefit from the Kia Stonic.
However, the higher loading edge of the Kia makes loading and unloading heavy items significantly more strenuous.
