Trunk comparison: Peugeot 3008 vs Seat Leon

Key Differences and Their Impact on Usability
The Peugeot 3008 offers a cargo area that is +7.1 in (≈12%) longer with the rear seat folded down than the SEAT Leon, and with the front seats upright, it even has a trunk depth that is +6.3 in (≈19%) greater. At its narrowest point, the loading width of the Peugeot is also +7.9 in (≈25%) wider.
The SEAT Leon, on the other hand, has a trunk opening that is 0.8 in (≈3%) higher, a depth measured from the loading edge to the trunk floor that is +5.5 in (≈127%) greater, and the trunk opening itself is 2.8 in (≈7%) wider. The loading edge of the Peugeot is 2 in (≈7%) higher above the road.
Practical consequences: Thanks to the significantly greater interior length and the wider narrowest point of the Peugeot 3008, longer and bulkier items can be transported more easily (e.g., long slats, furniture parts, or large suitcases), especially when the rear seats are folded down.
The larger narrow loading width also makes it easier to store wider luggage without side pinching.
In the SEAT Leon, the significantly greater depth from the loading edge to the trunk floor means that small, tall items can be more easily accommodated or better stacked; additionally, the slightly higher opening is marginally advantageous for very tall loading edges.
The higher loading edge of the Peugeot makes lifting heavy loads somewhat more strenuous, while the lower loading edge height of the SEAT Leon facilitates loading and unloading heavy items.
Overall, the Peugeot is more practical for long and wide cargo, while the SEAT Leon scores points for handling deeper or higher stacked loads and easier loading of heavy items.
