Trunk comparison: Audi Q2 vs VW Passat Wagon

Key Differences
The VW Passat Wagon offers significantly more cargo length: with the seats folded down, the trunk of the Passat is 22 in (39%) longer than that of the Audi Q2. Even with the first row of seats upright, the Passat is 13.8 in (45%) longer.
Additionally, the trunk opening of the Passat is 4.3 in (12%) wider than that of the Q2.
The Audi Q2, on the other hand, has a deeper cargo area from the loading edge to the trunk floor: this distance is 0.8 in (22%) greater in the Q2. Furthermore, the loading edge of the Q2 sits 4.7 in (19%) higher above the road than that of the Passat.
Impact on Usability
Due to the significantly greater cargo length in the Passat (39% and 45% more), long items (e.g., slats, skis, furniture parts) and larger amounts of luggage can be transported much more easily.
The wider opening dimension (12% more) reduces maneuvering when loading bulky or wide items and increases practical usability in everyday life (strollers, boxes, hardware store goods).
The greater depth in the Q2 means that items can sit deeper in the trunk — this can make stacking smaller parts easier and ensures that clothing or loose cargo is less visible. However, this advantage is moderate in practice due to the small absolute difference (0.8 in).
The significantly higher loading edge of the Q2 makes loading heavier or bulkier loads more strenuous: lifting into the trunk requires more effort, and rolling heavy items in and out is more limited. On the other hand, a higher loading edge reduces the risk that very long or low items accidentally slide out.
Summary
For users who regularly plan to carry long or wide loads, lots of luggage, or family trips, the VW Passat Wagon is clearly advantageous. The Audi Q2 remains more compact; its slightly deeper cargo well and higher loading edge offer only limited practical benefits but cause more effort when lifting heavy loads.
