Trunk comparison: Citroen C3 vs Opel Grandland

Key Differences

The Opel Grandland offers significantly more cargo length: +13 in (24%) with the seats folded down and +8.7 in (33%) with the front row upright compared to the Citroën C3. The width of the trunk opening is +7.9 in (23%) larger on the Grandland.

In contrast, the depth of the trunk (distance from loading edge → trunk floor) is +2.8 in (44%) greater in the Citroën C3 than in the Grandland.

Less relevant are smaller differences: The height of the trunk opening is only 0.8 in (3%) larger on the Grandland, the narrowest width is 2 in (5%) larger on the Grandland, and the loading edge height is the same on both models.

Impact on Usability

- Transporting long items (e.g., boards, skis, furniture parts): The Opel Grandland clearly has the advantage. The significantly longer cargo length both with folded seats and upright front row makes loading longer items easier and often possible without folding seats.

- Loading and unloading bulky/wide items: The 7.9 in wider opening of the Grandland makes maneuvering bulky cargo much easier. Together with the longer loading surface, this reduces the need to angle items awkwardly or make multiple attempts.

- Vertical volume / Securely sinking the cargo: The Citroën C3 offers a deeper cargo well due to the +2.8 in greater depth.

This helps when transporting taller or bulkier luggage that should stand upright and more easily prevents forward shifting. With the same loading edge height, lifting effort remains comparable, but some items sit deeper and more stably in the C3.

- Smaller differences such as opening height (+0.8 in) and narrowest width (+2 in) are rarely decisive in practice.

Conclusion

Those who frequently transport long or wide items are better served by the Opel Grandland.

For users who benefit from a deeper loading surface (more stable placement of tall luggage, lower stacking height above the loading edge), the Citroën C3 can be advantageous. The loading edge height is the same on both models, so lifting handling is comparable.
