Trunk comparison: BMW 3 Series Touring vs Seat Leon

Key Differences (highlighted: >10%)

The BMW 3 Series Touring offers a 10.2 in (≈17%) longer cargo area with the seats folded down and a 6.7 in (≈20%) greater depth with the front seats upright compared to the SEAT Leon. At the narrowest point in the trunk, the BMW is also 5.5 in (≈17%) wider.

The SEAT Leon, on the other hand, has a 3.1 in (≈11%) higher trunk opening, a significantly deeper cargo floor by +9.4 in (with an extremely high percentage figure in the original), and a 5.9 in (≈25%) higher loading edge above the road compared to the BMW.

The width of the trunk opening is 9% greater on the SEAT than on the BMW, but this difference is below the 10% threshold and is not highlighted here.

What are the practical implications of these differences?

Longer cargo area in the BMW: The greater interior length (both with folded and upright seats) makes the BMW better suited for long items such as slats, skis, long furniture parts, or sheets of material. It is also more practical for transporting longer boxes or pipes in everyday use.

Greater narrowest width in the BMW: The larger minimum width increases the chance of fitting wider or bulky items without adjustment or tilting. For wide boxes or bulky cargo, the BMW is advantageous.

Deeper cargo floor and higher opening in the SEAT: The SEAT offers more vertical space in the trunk (significantly deeper cargo floor) and a higher opening – this makes it easier to store tall or bulky items (e.g., bulky boxes, suitcases, or equipment that requires a lot of height).

Higher loading edge in the SEAT vs. lower in the BMW: The SEAT’s loading edge is significantly higher, meaning more lifting or carrying effort when loading heavy items. The BMW, with its lower loading edge, is more ergonomic and easier to load when handling heavy or large objects.

Practical conclusion: For users who often transport long or wide items (craftsmen, furniture purchases, ski transport), the BMW 3 Series Touring is generally more practical due to its greater length and wider narrow point.

For users who need to accommodate taller or bulkier cargo, the SEAT Leon offers advantages through its deeper cargo floor and higher opening — but at the cost of greater effort when lifting due to the higher loading edge.
