Trunk comparison: Opel Astra Wagon vs Renault Austral

Key Differences and Their Impact on Usability

In the comparison, it is particularly noticeable that the Opel Astra wagon offers significantly more usable length under an upright first row of seats: the Astra has +8.3 in (24%) longer trunk space when the front seats are upright.

This makes the Astra more practical for long, flat items (e.g., slats, long boxes, or skis) that need to be transported without folding down the seats.

The Renault Austral shows two more pronounced deviations in cargo geometry: the depth from the loading edge to the trunk floor is +2.4 in (300%) greater in the Austral, and the loading edge itself sits +7.5 in (32%) higher above the road.

Together, this means that in the Austral, the trunk floor lies significantly "deeper" below the loading edge, and the loading edge is considerably higher — this increases the available volume near the opening but makes loading more strenuous because heavy loads must be lifted higher.

Smaller differences without emphasis: the Astra has a 3.9 in wider width at the narrowest point, which favors wider items inside, while the Austral has a 2.8 in larger opening width, making it easier to insert bulky parts through the opening.

The opening height of the Astra is 2 in greater, and folded down (all seats) the Astra is only slightly longer (+2.4 in / 4%).

Practical conclusion: Those who often transport long, flat items without folding seats benefit from the Astra (more usable length).

Those who load bulky, voluminous items and benefit from a slightly larger opening width and deeper interior at the loading edge find advantages in the Austral — albeit at the cost of higher lifting effort when loading due to the higher loading edge.
