Trunk comparison: Renault Austral vs VW Tiguan Allspace

Key Differences
The VW Tiguan Allspace offers significantly more cargo length with the seats folded down: +11.8 in (19%) compared to the Renault Austral. Even with the first row of seats upright, the Tiguan is noticeably longer: +10.2 in (30%).
In contrast, the Renault Austral has a significantly larger trunk when all seats are upright: +15.4 in (83%). Also very noticeable is the greater depth (loading edge to trunk floor) of the Austral: +3.1 in (700%).
All other differences (opening height, loading edge height, narrowest width, opening width) are in the range of 1–2% and are negligible.
What impact does this have on usability?
The Tiguan Allspace is superior in situations where length matters: with folded seats, significantly longer items can be transported (furniture panels, skis, long boxes).
The greater loading length with the first row upright also offers flexibility when front seats are needed but longer cargo still needs to be accommodated.
The Renault Austral scores in everyday luggage and passenger use: with all seats upright, it offers significantly more trunk volume, making it more practical for families, vacation luggage, or frequent shopping.
The significantly greater depth of the trunk also means more usable vertical space behind the loading edge – boxes or bags can be stored deeper and more stably, and smaller items are more securely hidden in the trunk floor. However, this can make lifting very deep loads somewhat less convenient.
In short: For frequent transport of long goods and maximum cargo length, the Tiguan Allspace is the more suitable choice; for more usable volume with normal passenger seating and better stackability in the cargo area, the Renault Austral is better suited.
