Trunk comparison: Peugeot 308 SW 3-row vs Seat Leon

Key Differences (only >10% highlighted)

The Peugeot 308 SW (3-row) offers a significantly longer trunk with the "first row upright" configuration: +9.8 in (≈30%) in favor of the Peugeot.

However, when all seats are upright, the SEAT Leon has a significantly longer cargo space: +18.9 in (≈137%) in favor of the SEAT. The height of the trunk opening is 3.5 in (≈11%) higher on the Peugeot, which makes loading tall items easier.

The trunk depth (loading edge → trunk floor) is significantly larger on the SEAT Leon with +8.3 in (≈525%), while the loading edge of the SEAT Leon is 7.5 in (≈34%) higher above the road. Regarding the usable interior width at the narrowest point, the Peugeot is 7.9 in (≈25%) wider than the SEAT.

What are the implications of these differences for usability?

Space with full seating: When all seats are upright (maximum passenger capacity), the SEAT Leon is more practical for luggage or suitcases due to the significantly longer trunk (+18.9 in). Those who often travel fully occupied and still need to transport luggage benefit from the SEAT.

Flexibility with partially folded seats: In the "first row upright" configuration, the Peugeot clearly offers more cargo space (+9.8 in). This makes it advantageous for users who regularly carry passengers but also want to transport longer loads behind the remaining seats (e.g., skis, long luggage).

Loading bulky/tall items: The higher trunk opening (+3.5 in) and the greater narrowest interior width (+7.9 in) of the Peugeot make it easier to load and accommodate wide or tall cargo. Wide furniture pieces or bulky boxes tend to fit better through and sideways in the Peugeot.

Handling heavy loads and storage depth: The SEAT Leon offers a significantly greater depth behind the loading edge, allowing more volume to be used in depth.

However, its loading edge is considerably higher (+7.5 in), which makes lifting heavy items into the trunk more difficult. Those who frequently lift heavy loads have a clear ergonomic advantage with the Peugeot due to the lower loading edge.

Practical conclusion: For mostly loaded trips with full occupancy, the SEAT Leon scores better.

For more flexible use with bulky or heavy items as well as better pass-through capability and width, the Peugeot 308 SW (3-row) is more advantageous in everyday use. Smaller differences under 10% are usually negligible in practice.
