Trunk comparison: Ford Focus vs Hyundai i10

Key Differences
The Ford Focus offers significantly more cargo length: with the seats folded down, the trunk is +14.6 in (31%) longer, and with the front seats upright, it is even +11.8 in (64%) longer than the Hyundai i10. Additionally, the width of the trunk opening in the Focus is +3.9 in (11%) larger than in the i10. All other dimensional differences are below the 10% mark (e.g., opening height of the i10 +0.8 in / 3%, narrowest width i10 +0.8 in / 2%, loading edge height i10 +0.4 in / 1%); the depth (loading edge to floor) is the same.
Impact on Usability
The greater cargo length of the Focus specifically means more flexibility for long items like skis, furniture boards, or bicycles (partially or fully folded down).
Those who want to transport longer loads with the seats upright — such as tools, rolling suitcases, or upright sports equipment — benefit significantly from the Focus, as the difference here is particularly large at +64%.
The wider opening of the Focus makes loading and unloading wider items easier; bulky boxes or wide strollers also fit through more easily.
The i10, on the other hand, has a slightly higher opening height (+0.8 in) and +0.8 in more width at the narrowest point, which can be slightly advantageous when loading very tall but comparatively narrow items.
The minimally higher loading edge of the i10 (+0.4 in) is practically negligible but may require slightly more effort when frequently lifting heavy loads.
Conclusion: For users with regular needs for longer or wider cargo, the Ford Focus is clearly advantageous. The Hyundai i10 offers only small benefits in opening height and tight areas, which are less significant for most cargo items in everyday use.
