Trunk comparison: Audi Q5 vs VW Tiguan Allspace

Key Differences
The VW Tiguan Allspace offers a longer cargo area with the seats folded down: +9.4 in (14%) longer than the Audi Q5. Even with the first row of seats upright, the Tiguan is +6.7 in (18%) longer.
In contrast, the Audi Q5 has significantly more cargo length with all seats upright: +18.9 in (102%) compared to the Tiguan. Additionally, the depth of the trunk (loading edge → trunk floor) is significantly greater in the Audi Q5: +3.1 in (700%).
Impact on Usability
- VW Tiguan Allspace: The longer cargo area with folded seats makes the Tiguan more practical for long transports (e.g., slats, skis, long furniture parts) or when transporting large, flat items. It also offers more usable length for bulky cargo in certain seating configurations (first row upright).
- Audi Q5: With significantly more space when all seats are upright, the Q5 is more advantageous for everyday use when passengers regularly remain seated and a lot of luggage needs to be transported (suitcases, shopping, pets).
The greater trunk depth means more interior volume behind the loading edge, which especially helps when stacking or storing tall/bulky items.
- Other, smaller differences (not highlighted): The loading edge of the Tiguan is slightly higher (+1.2 in), making lifting somewhat more difficult; the narrowest width in the Q5 is minimally larger (+1.2 in), and the opening width in the Tiguan is slightly wider (+0.4 in).
These values have only a minor practical impact.
Conclusion
For regular transport of long items and flexible folding situations, the Tiguan Allspace is often more practical. For everyday use with passengers and lots of luggage without folding seats, the Audi Q5 is the better choice.
Which option is more sensible depends on the typical usage profile: long, bulky cargo → Tiguan; more luggage with full occupancy → Q5.
