Trunk comparison: Audi Q3 vs VW Tiguan
Summary of Key Measurements
The most noticeable difference concerns the depth of the trunk (loading edge to trunk floor): the Audi Q3 is +3.1 in (+800%) larger here than the VW Tiguan.
Other, but significantly smaller deviations are: the Audi Q3 has a +1.6 in (≈5%) higher trunk opening and a +1.2 in (≈3%) wider opening, the loading edge of the Q3 is +0.4 in (≈1%) higher above the road, and the Q3 offers +0.8 in (≈2%) more trunk length with the first row of seats upright.
The VW Tiguan has an advantage in usable cargo space with +2.4 in (≈4%) longer area when the seats are folded down; at the narrowest point, the Tiguan is +0.4 in (≈1%) wider.
Impact on Usability
The significantly greater depth in the Q3 practically means more space between the loading edge and floor — this makes it better suited for low-set or tall items, for hidden storage in the trunk floor, or when you want to securely accommodate bulky, tall cargo.
However, combined with the +0.4 in higher loading edge, this also means: heavy lifting over the loading edge is minimally more strenuous than in the Tiguan.
The higher and wider trunk opening of the Q3 (each +1.6 in and +1.2 in respectively) makes loading and unloading wide and tall items easier and reduces tight spots when fitting bulky parts. The Q3 is therefore overall more practical for voluminous, tall, or awkward cargo.
The Tiguan is slightly longer (+2.4 in) and marginally wider (+0.4 in) at the narrowest point when folded down.
This gives it a slight advantage when frequently transporting long, flat items (e.g., slats, long boxes), or when maximum loading length with folded seats is important. However, these advantages are small compared to the significant depth difference of the Q3.
Conclusion: For frequent transport of tall or voluminous cargo, the Audi Q3 is more practical due to the significantly greater depth and the somewhat higher/wider opening. Those who mainly transport long, flat items with folded seats benefit slightly more from the Tiguan.
