Trunk comparison: BMW iX1 vs VW Touran
Key Differences (>10% Deviation)
BMW iX1 offers significantly more cargo space with all seats upright: The iX1 has +22 in (+165%) more trunk space with upright seats than the Touran. This means considerably more usable space for luggage or shopping without folding the seats down.
VW Touran is longer with folded/upright rear seats: With folded seats, the Touran is +6.7 in (10%) longer — the figure is at the 10% threshold — and with the first row upright it is +4.3 in (+12%) longer than the iX1. This makes the Touran more flexible for long items once seats are folded or special seat configurations are used.
Higher trunk opening in the Touran: The trunk opening of the Touran is +5.5 in (+19%) higher than in the iX1. This facilitates loading tall or bulky items.
Higher loading lip on the BMW iX1: The loading lip of the iX1 is +3.9 in (+16%) higher above the road than the Touran. This means more lifting effort when loading heavy items.
Depth from loading lip to trunk floor (relative significance): According to the data, the iX1 has +0.4 in (+100%) more depth than the Touran. The absolute difference is small, but the percentage appears large — indicating very small base values.
Impact on Usability
Everyday/Passenger use: The iX1 clearly has the advantage in daily use when seats are used (none or few folded seats): significantly more storage space with upright seats means more luggage room for family/daily use without modifications.
Transporting long items: The Touran is better suited if long items or variably configurable cargo space are regularly needed (folded seats / special seat configurations). The greater length with folded or certain seat positions allows longer cargo pieces.
Tall cargo and loading handling: The higher trunk opening in the Touran makes it easier to accommodate tall items. Conversely, the higher loading lip in the iX1 makes lifting heavy items into the trunk more difficult; this can be a disadvantage when regularly transporting heavy loads.
Practical note on depth: The stated relative doubling of depth in the iX1 is absolutely very small (+0.4 in) and has limited practical impact on total volume.
Smaller Differences (≤10%)
Widths: The narrowest point of the trunk is only +2 in (+5%) wider in the Touran, while the width of the trunk opening is +2 in (+5%) larger in the iX1. These differences are minor and affect usability only in borderline cases (very wide items).
