Trunk comparison: Renault Clio vs Tesla Model 3

Key Differences
In terms of cargo space lengthwise, the Tesla Model 3 is significantly larger: with the seats folded down, the trunk of the Tesla is 21.7 in (≈42%) longer, and with the front seats upright, it is 14.2 in (≈51%) longer than the Renault Clio.
In contrast, the Clio offers more vertical space at the opening: the height of the Clio's trunk opening is 8.7 in (≈42%) higher than that of the Model 3. Additionally, the depth (loading edge to trunk floor) is +26 in (≈600%) greater in the Clio.
The loading edge of the Tesla, however, sits 16.9 in (≈179%) higher above the ground than that of the Clio. The narrowest width in the trunk is only slightly larger in the Clio (+2.4 in / 6%), and the width of the trunk opening is the same for both models.
Impact on Usability
Due to the significantly longer cargo lengths, the Model 3 is better suited for long, flat items (e.g., slats, long boxes, skis) and offers noticeably more storage space for bulky, lengthwise cargo when the seats are folded down.
The Clio scores points in vertical usability and handling of heavy or tall items: the higher opening height makes it easier to load tall boxes or items with standing height, and the greater depth (loading edge → floor) provides more vertical space inside.
Additionally, the loading edge in the Clio is significantly lower, making lifting heavy loads into the trunk more ergonomic and easier.
Practical consequence: For transport tasks requiring long, flat objects or maximum length, the Model 3 is the better choice.
For frequent loading and unloading of heavy or tall items, as well as easier handling at the loading floor, the Clio is more advantageous in everyday use. Smaller width differences are negligible.
