Trunk comparison: Audi Q7 vs BMW iX1

Key Differences

The Audi Q7 offers significantly more usable length and a larger opening: with the seats folded down, the trunk of the Q7 is 16.1 in longer (+25%), and with the first row of seats upright, it is 11.4 in longer (+32%) than the BMW iX1. Additionally, the width of the Q7's trunk opening is 4.7 in wider (+11%).

Other dimensions differ less: The Q7's trunk opening is 1.2 in taller (+4%) and the narrowest width is 3.1 in wider (+8%) — both under the 10% mark. The loading edge of the Q7 sits 2.4 in higher above the ground (+8%) than the iX1.

A notable relative difference exists in depth (loading edge → trunk floor): the BMW iX1 is 0.8 in deeper here, indicated as +100% compared to the Q7 (deeper "well" below the loading edge).

Impact on Usability

Due to the significantly greater length with folded and upright seats plus the wider opening, the Audi Q7 is clearly better suited for long and bulky loads (e.g., furniture parts, long sports equipment, bulky boxes). The larger opening width makes loading and unloading wide items easier.

The BMW iX1 scores with a deeper trunk well below the loading edge and an overall lower loading edge. Practically, this means heavy luggage is easier to lift from the iX1 because the loading edge is lower, and small items fit better in the deeper tray.

However, long or very wide items are harder to accommodate in the iX1 due to the shorter loading floor and narrower opening.

In short: For volume and long/bulky loads, the Audi Q7 is better; for easier lifting of heavy items and a deeper loading well, the BMW iX1 can offer advantages.
