Trunk comparison: Renault Austral vs Tesla Model Y

Key Differences and Practical Consequences

The two vehicles clearly differ in how they accommodate cargo: The Tesla Model Y offers noticeably more cargo length, while the Renault Austral has advantages in depth, opening width, and trunk sill height.

More length in the Tesla: The Tesla Model Y has +13.4 in (21%) more cargo length with the seats folded down and +9.8 in (29%) more with the first row upright than the Renault Austral.

In practice, this means that long items (e.g., slats, long boxes, skis, smaller furniture) can be accommodated much more easily in the Model Y—often even without fully folding down the seats.

Greater depth in the Renault: The Renault Austral has a significantly greater depth (trunk sill to trunk floor): +3.1 in (700%) compared to the Model Y.

Practically, this means that low-built, bulky, or loose items stand more securely in the Austral and are less likely to shift; additionally, there is more usable volume below the trunk sill. However, a deep recess can make it harder to retrieve very flat loads.

Higher and wider opening in the Renault: The Austral’s trunk sill is +3.1 in (11%) higher above the road, and the width of the trunk opening is +4.3 in (11%) larger than in the Model Y.

The larger opening makes loading wider items (strollers, wide boxes) easier. However, the higher trunk sill makes lifting heavy items more strenuous and loading heavy cargo less comfortable than in the lower-lying Model Y.

Other smaller differences (not highlighted): The height of the trunk opening is only +1.6 in (6%) larger in the Austral, and the narrowest width inside the trunk is +1.6 in (4%) larger in the Austral—differences that are usually less relevant in practice.

Conclusion: For long cargo and easy, back-friendly loading, the Tesla Model Y is better suited. For securely storing low, bulky items and wider cargo, the Renault Austral offers advantages—but at the cost of a higher trunk sill that makes lifting heavy items more difficult.
