Trunk comparison: Kia Stonic vs Renault Clio

Key Differences

The two clearly standout differences lie in the depth of the trunk (loading edge → trunk floor) and the height of the loading edge above the road. The Renault Clio has a significantly deeper cargo well (+23.2 in / +328% compared to the Kia Stonic).

Conversely, the loading edge of the Kia Stonic sits considerably higher above the roadway (+20.9 in / +221% compared to the Clio).

Practical Implications

Renault Clio – Advantages:

• The significantly deeper trunk well offers more usable volume below the loading edge. This is advantageous for bulky or tall items that can sink deeper, and for storing luggage that needs lateral support.
• Due to the lower loading edge, loading smaller and heavier items is generally less strenuous — less lifting required.
• Disadvantage: the deep well creates a "step" effect when loading and unloading: heavy, flat items often have to be guided over an edge when sliding them in, and storing very tall items can sometimes be more complicated due to the lower position.

Kia Stonic – Advantages:

• The significantly higher loading edge means more lifting is required when loading — this is more tiring with heavy loads.
• Since the trunk well in the Stonic is much shallower (compared to the Clio), there is practically little or only a slight step behind the loading edge. This simplifies sliding in bulky, flat items once they are lifted over the loading edge.
• The slightly greater opening height of the Stonic (≈+2 in / 7%) can make fitting tall items easier, but this is secondary compared to the differences mentioned above.

Other, Smaller Differences

All other deviations are under 10%: With seats folded down, the Stonic is about 2 in (4%) longer; with the first row upright, the Clio is about 0.8 in (3%) longer.

The narrowest trunk width is about 1.6 in (4%) larger in the Stonic, while the opening width is about 0.4 in (1%) larger in the Clio. These differences are usually barely noticeable in everyday use and only slightly affect practical usability.
