Trunk comparison: BMW X4 vs Peugeot 308 SW 3-row

Main Differences

Key differences (>10%) at a glance: The BMW X4 offers with seats folded down a 10.6 in (19%) longer cargo area and with seats upright a significantly longer cargo area by 26.4 in (191%). The trunk opening of the Peugeot is 7.5 in (27%) higher than that of the BMW.

The loading edge of the BMW is 9.1 in (41%) higher above the road. Additionally, the depth of the BMW trunk (measured from loading edge to trunk floor) is 1.6 in (100%) greater than the Peugeot's.

Implications for Usability

Volume and cargo area: The BMW X4 offers more usable length both with seats upright and folded down. This makes it more practical for long items, larger amounts of luggage, or when regularly transporting longer cargo.

Loading height and handling: The significantly higher loading edge of the BMW (+9.1 in) increases the lift height when loading — heavy cargo must be lifted higher. The Peugeot has the advantage here with a lower loading edge, which makes loading and unloading heavy items easier.

Opening height and interior shape: The 7.5 in higher trunk opening on the Peugeot facilitates loading tall items and overall access.

The greater depth in the BMW (more distance from loading edge to trunk floor) creates additional storage space downward, useful for low-lying or stackable cargo, but combined with the higher loading edge can make handling more difficult.

Conclusion: Those who need longer or larger cargo and more usable cargo space are better served by the BMW X4. Those who frequently load heavy or tall items and prefer lower lift heights benefit more from the Peugeot 308 SW (3-row).
