Trunk comparison: Hyundai IONIQ vs Opel Astra Wagon

Key Results (Highlighted Differences >10%)
Several differences stand out in the comparison: The Opel Astra Wagon offers with the front seats upright a cargo floor length that is 6.3 in (≈18%) longer and a trunk opening that is 4.7 in (≈18%) higher than the Hyundai IONIQ.
The trunk opening of the Astra is also 4.3 in (≈12%) wider. In contrast, the Hyundai features a significantly greater depth between the loading edge and the trunk floor: this is 3.9 in (≈500%) larger, and the loading edge itself is 5.9 in (≈25%) higher above the road than in the Astra.
Impact on Usability
For everyday use and transporting large, bulky, or taller items, the Opel Astra Wagon has the advantage: the higher and wider opening as well as the greater usable length with the rear seats upright make it easier to load long or bulky parts (e.g., furniture panels, long suitcases, or bulky boxes).
The lower loading edge in the Astra (indirectly indicated by the higher loading edge height of the Hyundai) also reduces the effort needed to lift items in.
The Hyundai IONIQ offers more interior vertical space behind the loading edge due to the significantly greater depth between the loading edge and trunk floor, which can be useful when stacking heavy items or transporting longer, flat-lying loads.
At the same time, the higher loading edge makes loading more strenuous, and the lower opening height of the IONIQ limits the accommodation of tall items despite the greater interior depth.
The difference in total length with folded seats is marginal at 1.2 in (≈2%) and has little practical effect.
