Trunk comparison: Ford S-MAX vs Hyundai IONIQ

Summary of Measurements

The Ford S‑Max offers significantly more usable length and a larger opening: +13.8 in (21%) more trunk length with folded seats, +8.3 in (23%) more length with the first row upright, and a +10.6 in (41%) higher trunk opening. Additionally, the width of the opening in the S‑Max is +4.7 in (13%) larger.

In contrast, the Hyundai IONIQ has a significantly greater trunk depth (loading edge → floor) of +3.5 in (300%) and a +6.7 in (30%) higher loading edge above the road. The narrowest trunk width differs by only +1.2 in (3%) and is therefore negligible.

Impact on Usability

The larger length dimensions and the higher and wider opening of the S‑Max mean practical advantages when transporting long or bulky items: furniture, slats, or long boxes can be loaded more easily — even without folding down the front row of seats.

The significantly lower loading edge of the S‑Max makes lifting and pushing heavy loads easier.

The IONIQ offers more volume in the cargo well due to the greater trunk depth; items lie deeper and can be stored more discreetly or securely.

At the same time, the higher loading edge restricts easy loading (more lifting or less convenient sliding through), and the lower opening height limits the transport of very tall or bulky cargo.

Conclusion: For frequent loading of long, tall, or bulky items and for easy handling of heavy loads, the Ford S‑Max is clearly more practical. The Hyundai IONIQ scores with a deeper cargo well for more usable volume but requires compromises when loading and unloading as well as when accommodating very large items.
