Trunk comparison: BMW 3 Series Touring vs BMW X1

Key Differences (highlighted >10%)

The BMW 3 Series Touring offers an accessible cargo floor that is 3.9 in (11%) longer with the rear seats upright than the BMW X1. The X1 has a depth between the loading edge and trunk floor that is 0.8 in (200%) greater, and the loading edge sits 4.3 in (18%) higher above the road than in the 3 Series Touring.

The height of the trunk opening is the same in both models.

Implications for Usability

The longer cargo floor of the 3 Series Touring with the rear seats upright makes it more practical when transporting long items without folding down the rear seats (e.g., slats, skis in the base, long boxes).

When the seats are fully folded down, the vehicles differ by only 7% in favor of the 3 Series (thus largely comparable).

In the X1, the slightly greater width at the narrowest point and the wider trunk opening make loading wider items easier, but the advantage here is under 10% and therefore moderate.

However, the higher loading edge of the X1 means that heavy cargo must initially be lifted higher — making loading physically more strenuous and less practical for frequent heavy loads.

The greater depth from the loading edge to the trunk floor in the X1 (0.8 in difference) can provide slightly more vertical space immediately behind the loading edge but does not compensate for the disadvantage of the higher loading edge when lifting heavy items.

In summary: For longer items without folding down the rear seats, the 3 Series Touring is clearly advantageous. For occasional transport of wider or bulkier items, the X1 has slight advantages in width and opening, but the higher loading edge makes handling heavy loads less comfortable.
