Trunk comparison: Hyundai i10 vs VW Polo

Key Differences
The VW Polo offers significantly more cargo length: with the seats folded down, it is 7.9 in (17%) longer, and with the front seats upright, it is 7.5 in (40%) longer than the Hyundai i10. The Hyundai i10 scores in the vertical dimension: the trunk opening is 5.1 in (19%) higher and the depth from the loading edge to the trunk floor is 3.9 in (125%) greater than in the Polo.
The loading edge height and the narrowest widths differ very little (loading edge height is the same; width differences of 1–0.8 in or 1–2% are negligible).
Impact on Usability
Due to the larger length dimensions, the Polo is the better choice for longer or flat items and generally for more usable length in the cargo space — making it more practical for weekend trips, longer luggage, or transporting longer parts with the seats folded down.
The i10, on the other hand, offers more vertical space: the higher opening and significantly greater depth below the loading edge make it easier to load tall or bulky items and reduce the chance of luggage protruding over the loading edge.
Practically speaking: taller/bulkier items are easier to store in the i10, while longer items fit better in the Polo.
Since the loading edge height is the same, the effort required to lift cargo is hardly different. Small width differences are irrelevant in everyday use.
Conclusion: those who frequently transport long or flat loads benefit from the Polo; those who need more vertical capacity and a higher opening for bulky or tall cargo are better served by the i10.
