Trunk comparison: Hyundai IONIQ vs VW Polo

Summary of the Biggest Differences

The Hyundai IONIQ offers significantly more usable length and depth in the trunk: with the seats folded down, the trunk is 9.8 in (≈18%) longer than the VW Polo, and with the front seats upright, it is also 9.8 in (≈38%) longer.

Additionally, the depth (distance from loading edge → trunk floor) of the IONIQ is 1.6 in (≈50%) greater.

Smaller differences: the Polo's trunk opening is 1.2 in (≈5%) higher, the IONIQ's loading edge is 1.6 in (≈6%) higher above the ground, the narrowest width is about 0.8 in (≈2%) wider on the Polo than on the IONIQ, and the width of the opening is 0.8 in (≈2%) larger on the IONIQ.

Impact on Usability

More length with folded seats and especially with the front seats upright makes the IONIQ advantageous for longer items (e.g., slats, skis, furniture parts) and for transport tasks where seats should not be fully folded down. Therefore, the IONIQ is better suited for users who frequently transport bulky or long cargo.

The significantly greater depth (loading edge → trunk floor) in the IONIQ increases the usable vertical volume: more space for stackable luggage or taller items inside the trunk.

This helps with securely storing boxes and bags but can make lifting heavy loads somewhat more strenuous in combination with the slightly higher loading edge.

The Polo only scores minor advantages: the slightly higher trunk opening (+1.2 in) minimally eases passing very tall items through, and the slightly greater width at the narrowest point can help when fitting particularly wide but not very long items.

However, these differences are under 10% and are usually hardly noticeable in everyday use.

Conclusion: Those who regularly transport long or bulky cargo benefit from the Hyundai IONIQ's significantly greater length and depth. Those who primarily value easy loading and unloading of normal luggage or prefer a more compact behavior find only marginal advantages in the VW Polo.
