Trunk comparison: BMW X5 vs Peugeot 3008

Key Differences

With the rear seats folded down, the BMW X5 offers a cargo area that is 7.5 in (11%) longer than the Peugeot 3008. The depth of the trunk (loading edge to trunk floor) is 3.9 in (1000%) greater in the Peugeot 3008 compared to the BMW X5.

Impact on Usability

The greater length of the BMW X5 with folded seats makes it significantly more practical for long items such as furniture parts, long boxes, or skis — they can be loaded flatter and straighter without improvised angles or tilting.

Combined with the slightly wider usable area of the X5 (width at the narrowest point +3.5 in and opening width +2.8 in), this makes storing bulky but elongated cargo easier.

The considerably greater depth in the Peugeot means more vertical space behind the loading edge: luggage can sit deeper, creating more internal volume overall, and higher stacks are possible. This is advantageous for box-shaped or bulky cargo where interior height matters.

At the same time, a deeper loading floor can make lifting heavy items over the loading edge more difficult because more lifting effort is required; for frequent loading and unloading of heavy loads, the shallower X5 cargo area is therefore more ergonomic.

Other differences (less than 10%) such as the 2 in longer loading length with the first row upright in the X5, the 0.8 in higher opening height of the X5, or the 0.4 in higher loading edge of the Peugeot are minor and only marginally affect everyday usability.

In summary: For long, bulky cargo and easier handling of heavy items, the BMW X5 is better suited; for more internal volume and stacking suitcases or deeply seated cargo, the Peugeot 3008 offers advantages.
