Trunk comparison: Opel Grandland vs Renault Austral

Key Differences

There are several differences between the Opel Grandland and Renault Austral in trunk volume and dimensions. The Opel Grandland offers a cargo space that is 3.5 in (6%) longer with the seats folded down and 1.2 in (3%) more length with the first row of seats upright — both relatively minor differences.

The width at the narrowest point is only 2% greater in the Grandland, the loading sill height is the same for both models, and the width of the trunk opening in the Austral is 4% larger.

Two differences over 10% stand out clearly: The height of the trunk opening in the Opel Grandland is 3.1 in or 11% higher than in the Renault Austral, and the trunk depth (distance from loading sill to trunk floor) in the Grandland is 3.1 in or 100% greater.

Impact on Usability

The greater opening height (+11%) of the Grandland significantly facilitates loading tall or bulky items — boxes, suitcases, or furniture can be loaded with less lifting or tilting.

The significantly greater depth of the Grandland (+100%, 3.1 in) means there is more storage space "downwards" inside; items can be stored deeper and thus more stably, and longer items more often fit entirely in the trunk.

Since the loading sill is the same height on both models, lifting the load remains comparable, but the Grandland gains in interior volume due to height and depth.

The Renault Austral scores with a slightly wider trunk opening (+4%), which makes loading very wide items easier. For bulky but flat or wide loads, the Austral can therefore be more practical in specific cases.

Overall, however, the Opel Grandland is better suited for tall, deep, or voluminous cargo; the Austral remains advantageous for very wide but not deep loads.
