Trunk comparison: Opel Astra Wagon vs Renault Austral

Key Differences (highlighted: >10%)

Main advantages of the Opel Astra Sports Tourer compared to the Renault Austral: the folded rear seats provide a +7.1 in (≈11%) longer cargo floor; with the first row of seats upright, there is +6.3 in (≈19%) more cargo or usable length. The trunk opening of the Astra is +4.7 in (≈16%) higher.

The depth of the cargo area (from loading edge to trunk floor) is +2.4 in (≈75%) greater in the Astra. Conversely, the loading edge of the Renault Austral is +6.7 in (≈28%) higher above the road than the Astra.

Smaller differences (width at the narrowest point +1.2 in, opening width on the Austral +2 in) are under 10% and therefore secondary.

Impact on Usability

Longer cargo floor (Astra): With an additional 16–7.1 in of usable length, the Astra can accommodate significantly longer items without awkward positioning or angling — for example, long slats, skis, furniture parts, or folded bicycles.

This means more flexibility when transporting bulky, longer cargo with both folded and upright seats.

Higher trunk opening (Astra): The +4.7 in higher opening makes loading tall items easier and reduces tipping when loading. Large boxes, plants, or bulky items can be loaded more easily and with less effort.

Deeper cargo area (Astra): The greater depth between the loading edge and trunk floor creates more interior volume and allows secure storage of taller items without them immediately reaching the rear window.

However, a deeper cargo floor can make removing very heavy items somewhat more cumbersome (more lifting from depth).

Lower loading edge (Astra) vs. higher loading edge (Austral): The +6.7 in higher loading edge of the Austral makes lifting heavy items into the trunk noticeably more strenuous.

For frequent loading of heavy loads, strollers, or groceries, the Astra’s lower loading edge is noticeably more practical. The Austral’s position is better suited if items are mostly slid in or if a higher vehicle profile is desired, but overall less practical for manual lifting.

Width differences (minor): The slightly larger opening width of the Austral (+2 in) marginally facilitates loading wide boxes or furniture crosswise, while the minimally greater narrow interior width of the Astra (+1.2 in) is hardly decisive in practice.

Conclusion

For users who frequently transport long, tall, or heavy items (craftsmen, moving, sports equipment, family life with strollers), the Opel Astra Sports Tourer offers noticeable advantages: more usable length, higher opening, larger interior volume, and a significantly lower loading edge make loading easier and increase everyday practicality.

The Renault Austral scores slightly in opening width but has disadvantages with its higher loading edge and lesser depth/length for long, tall, or heavy cargo.
