Trunk comparison: Renault Austral vs VW ID.4

Key Insight

Both models differ in several loading dimensions: The VW ID.4 has a loading floor that is 3.5 in (6%) longer with the seats folded down and 3.1 in (9%) longer with the first row of seats upright.

The trunk opening of the ID.4 is 2.8 in (10%) higher, and the width at the narrowest point is 0.8 in (2%) greater on the ID.4. The Renault Austral offers an opening that is 2 in (5%) wider, but its load lip is 1.6 in (5%) higher above the ground than that of the ID.4. Notably, the depth of the trunk (load lip to trunk floor) is greater in the VW ID.4 by +0.8 in, which corresponds to a relative difference of 25%.

Impact on Usability

The 25% greater depth of the ID.4 means practically more usable space directly behind the load lip: bulky or taller items can be pushed further into the cargo area, smaller stacks behind the load lip are easier to manage, and there is more room for irregularly shaped cargo.

Note: The absolute difference is only 0.8 in, so the practical gain may vary depending on the specific luggage — but for a tight fit, this difference can be decisive.

The slightly greater overall length of the ID.4 (6–9% more) helps with transporting longer items, though the advantage is rather moderate (a few centimeters more depth).

The higher trunk opening of the ID.4 (+2.8 in / 10%) allows for models with somewhat greater height through the tailgate but is right at the threshold for being a highlight.

The wider opening of the Austral (+2 in) makes it easier to load wider items, while the higher load lip of the Austral (+1.6 in) makes lifting heavy loads somewhat more difficult compared to the ID.4 with its lower load lip.

In summary: for better handling of bulky/taller cargo and easier loading, the ID.4 has the edge; for wider cargo pieces, the Renault opening can be advantageous. Most differences are small to moderate — the depth of the ID.4 is the most significant relative deviation.
