Trunk comparison: BMW 5 Series Touring vs Peugeot 308 SW 3-row

Key Differences

The BMW 5 Series Touring offers significantly more cargo length: With the seats folded down, the trunk of the BMW is 17.7 in (31%) longer, and with the seats upright even 29.1 in (211%) longer than the Peugeot 308 SW.

On the other hand, the Peugeot scores with the opening and the loading edge: The trunk opening of the Peugeot is 7.5 in (27%) higher, the depth from the loading edge to the trunk floor is 1.6 in (300%) greater, and the loading edge itself is significantly lower on the Peugeot – the BMW sits 3.9 in (18%) higher above the road here.

Smaller width differences (narrowest width +2.4 in BMW; opening width +2.8 in Peugeot) are under 10% and therefore less relevant.

Implications for Usability

For long items and high cargo capacity in length, the BMW is clearly advantageous: The significantly greater cargo length (especially in everyday use with seats upright) allows transporting longer items without folding seats and offers more overall storage space.

This makes the BMW more practical for users who regularly need to transport long loads or large luggage.

The Peugeot, on the other hand, is more practical in handling and with bulky/taller items: The higher opening and greater depth to the trunk floor provide more height and space at the cargo entry, and the low loading edge combined with the smaller distance to the road makes loading and unloading heavy or awkward loads much easier.

This reduces physical effort and makes the Peugeot more favorable for frequent loading/unloading or for bulky, tall objects.

Conclusion: BMW = greater length capacity and more storage space for long loads. Peugeot = easier loading/unloading, more pass-through height, and better suitability for tall/bulky objects. Width differences are minor and have little practical impact.
