Trunk comparison: BMW X4 vs Renault Austral

Key Differences

The most noticeable difference concerns the usable loading length: With the first row of seats upright, the trunk of the BMW X4 is 6.3 in (19%) longer than that of the Renault Austral. This is the only deviation over 10%.

Other Differences (under 10%)

Other deviations are significantly smaller: When all seats are folded down, the trunk of the BMW X4 is 4.7 in (8%) longer. The height of the trunk opening of the Renault Austral is 1.2 in (4%) higher. The width of the Austral's trunk opening is 3.5 in (9%) larger.

The depth (loading edge to trunk floor) is the same in both models. The loading edge of the BMW X4 is 0.4 in (1%) higher above the road, and the narrowest interior width of the BMW is 0.4 in (1%) larger.

Impact on Usability

The significantly greater loading length of the BMW X4 with the first row of seats upright makes it better suited for long items (e.g., furniture parts, slatted frames, skis) without requiring major modifications. This leads to more flexibility when transporting longer loads.

The Renault Austral offers a higher trunk opening and a wider opening, which facilitates loading and unloading bulky or wide items — especially bulky boxes or larger crates. The slightly lower loading edge of the Austral also makes lifting heavy loads a bit easier, even though the difference is small.

Overall, this means: For users who frequently transport long items, the BMW X4 is more advantageous. For those who regularly need to load and unload wide or bulky goods, the Renault Austral offers more practical opening dimensions.
