Trunk comparison: Peugeot 3008 vs Seat Ibiza

Key Differences
In terms of volume and shape of the cargo space, the Peugeot 3008 shows clear advantages in length and opening width: with the seats folded down, the trunk of the Peugeot is 10.2 in (18%) longer, and with the first row of seats upright, it is even 12.2 in (46%) longer than in the Seat Ibiza.
The width of the trunk opening is also significantly larger in the Peugeot: plus 5.5 in (16%).
On the Ibiza side, the depth of the trunk (distance from loading edge to trunk floor) is significantly greater: the Ibiza has +3.1 in (73%) here. Additionally, the loading edge in the Peugeot sits higher: plus 4.3 in (16%) above the road.
Smaller differences (≤10%) are the height of the trunk opening (Ibiza +1.6 in / 5%) and the narrowest trunk width (Peugeot +0.8 in / 2%), which are not highlighted here.
What are the implications of these differences for usability?
The longer dimensions and wider opening of the Peugeot 3008 make it more practical for long or bulky items: furniture parts, skis, long boxes, or strollers can be accommodated more easily, especially when the rear seats are folded down. The larger opening width also facilitates loading and unloading wider luggage.
The significantly greater depth in the Seat Ibiza means that items can be placed further down in the cargo space — this can be advantageous when transporting stacks with higher drop height or when hiding luggage under a cover.
However, because the loading edge of the Peugeot is higher, loading and unloading there requires more lifting effort; heavy items are generally easier to lift into the Ibiza.
In summary: For transports where length and width are decisive (long items, wide loads), the Peugeot 3008 is the better choice. For simple, low sliding in of cargo or when lifting at a low loading edge is important, the Seat Ibiza scores despite its smaller overall length due to its greater trunk depth usability.
