Trunk comparison: BMW X5 vs Renault Austral
Key Differences
Trunk length with seats folded down: BMW X5 is 10.2 in (16%) longer. This results in more usable loading length for long items like slats, furniture parts, or long skis.
Trunk length with front row seats upright: BMW X5 is 7.1 in (21%) longer. This means: in everyday situations (rear passengers seated), the X5 offers significantly more cargo space for luggage and shopping.
Trunk depth (loading edge → trunk floor): Renault Austral is 2.8 in (700%) deeper. Practically, this means more vertical volume behind the loading edge (deeper footwell), which can better accommodate bulky, taller items.
At the same time, a greater height difference to the loading edge is created, which makes lifting very heavy items somewhat more difficult.
Trunk width at the narrowest point: BMW X5 is 4.3 in (11%) wider. The X5 can therefore better accommodate wider items inside; dimensions that would fail at the narrowest point in the Austral fit more easily in the X5.
Impact on Usability
For long loads and transports where length is crucial (e.g., slats, long boxes, skis), the BMW X5 has a clear advantage: it offers noticeably more loading length both with folded seats and with the front row upright.
When it comes to high volume behind the loading edge (e.g., crates, buckets, bulky, tall items), the Renault Austral scores with its significantly deeper trunk floor.
The additional depth volume allows for taller items or more stacking volume. However, it should be noted that the greater height difference to the loading edge can make handling very heavy loads more difficult.
The larger narrowest interior width in the X5 improves the accommodation of wide loads. The slightly larger opening width of the Austral (only ~1.2 in) helps when loading bulky items but does not compensate for the smaller interior width at the narrow point.
Smaller differences such as the 2.8 in higher trunk opening on the X5 (10%) or the 0.4 in higher loading edge are secondary for most users: they slightly ease handling but do not fundamentally change loading capacity.
