Trunk comparison: Mazda Mazda CX-5 vs Seat Leon

Key Differences

The Mazda CX-5 has a 8.3 in (14%) longer cargo space with the seats folded down and a 5.1 in (16%) longer cargo space with the first row of seats upright compared to the SEAT Leon.

Inside the trunk, the narrowest point is 9.4 in (30%) wider in the Mazda. In contrast, the depth from the loading edge to the trunk floor is 7.9 in (400%) greater in the SEAT Leon than in the Mazda.

Smaller differences under 10% include: trunk opening height (SEAT Leon +0.4 in), loading edge height above the road (Mazda +0.4 in), and trunk opening width (SEAT Leon +1.2 in).

Impact on Usability

Thanks to the larger length and width dimensions, the Mazda CX-5 is more practical for long and wide cargo: furniture parts, skis, slats, or furniture boards can be transported much more easily with the seats folded down, and even with the first row upright, there is more usable depth.

The greater narrowest width also means that wide items are more likely to fit between the wheel arches.

The SEAT Leon offers a deeper cargo floor due to the significantly greater depth (loading edge → trunk floor). This creates more volume for low but bulky cargo (e.g., suitcases, shopping crates) that can be "sunk" below the loading edge.

However, disadvantages of this design include a narrower, shorter interior (limiting wide and long items) and that removing heavy items can be more difficult due to the lower floor position (requiring more lifting or pulling out).

In short: for long and wide cargo, the Mazda CX-5 is the better choice; for additional deep storage space for rather low luggage, the SEAT Leon can offer advantages but loses flexibility for large or wide loads.
