Trunk comparison: BMW 3 Series Touring vs VW Taigo

Biggest Differences (>10%)
The BMW 3 Series Touring offers a significantly longer loading floor with the seats folded down: +7.5 in (12%) more loading length than the VW Taigo. Even with the first row of seats upright, the BMW is longer: +7.1 in (22%).
The VW Taigo scores in vertical dimension and accessibility: the height of the trunk opening is +3.1 in (11%) larger than the BMW.
The depth of the trunk (distance from loading edge to trunk floor) is significantly greater in the Taigo: +7.5 in (1900%). Additionally, the loading edge of the Taigo sits +5.9 in (25%) higher above the road than the BMW.
Impact on Usability
Loading length (BMW advantage): Due to the longer loading floor of the BMW, long items (e.g., slats, skis, long furniture parts) can be transported more easily—especially when the rear seats are folded down. Those who regularly need to carry bulky, elongated cargo have a clear advantage in the BMW.
Vertical capacity and loading height (VW advantage and disadvantage): The higher trunk opening of the Taigo makes it easier to accommodate taller items and to load bulky but not too deep objects.
The significantly greater "depth" of the Taigo indicates more space between the loading edge and trunk floor, which in practice can mean more usable storage volume below the loading edge or a deeper cargo compartment.
Loading ergonomics (BMW advantage): The 5.9 in lower loading edge of the BMW makes lifting heavy items into the vehicle noticeably easier and more back-friendly.
Even though the Taigo offers more vertical capacity, the higher loading edge complicates handling heavy loads and can be a disadvantage with frequent loading.
Combination of factors: Those who transport long, flat cargo or frequently load and unload heavy items benefit overall from the BMW 3 Series Touring (more length, lower loading edge).
Those who often need taller items or voluminous but not excessively long cargo and value deeper loading options have advantages with the VW Taigo—despite the higher loading edge.
Additional Notes
Small width differences are impractical: The width at the narrowest point is only 4% larger in the Taigo and the width of the trunk opening is only 1% larger in the BMW—both hardly noticeable in everyday use.
