Trunk comparison: Audi Q3 vs VW Taigo

Largest Measurable Differences
The depth of the trunk (loading edge to trunk floor) is 4.3 in (+122%) greater in the VW Taigo than in the Audi Q3. The width of the trunk opening is 5.1 in (+13%) greater in the Audi Q3 than in the VW Taigo.
Other, smaller differences: The Audi Q3 offers about +3.9 in (6%) more cargo length with the seats folded down and +3.1 in (10%) more length with the front seats upright.
The height of the Taigo's trunk opening is +0.8 in (3%) higher. The loading edge height is the same in both models, and the narrowest trunk width in the Q3 is only +0.4 in (1%) greater.
Impact on Usability
VW Taigo — deeper cargo well: Due to the significantly greater depth, the Taigo offers more vertical space and thus more usable volume for tall or bulky cargo, shelving crates, or luggage that fits into the well.
However, the greater depth can affect handling: heavy luggage lies lower and must be lifted higher when removing it, making stowing deeply placed items somewhat more cumbersome.
Audi Q3 — wider opening: The significantly greater width of the trunk opening makes loading and unloading wide or bulky items (furniture parts, crates, angled objects) easier.
Combined with the slightly longer cargo length (with seats folded or front seats upright), the Q3 is more practical for long and wide cargo that must be maneuvered through the opening.
Common points: The same loading edge height means comparable ergonomics when overcoming the threshold; smaller differences in length, opening height, and narrow width are usually only relevant in edge cases.
What Does This Mean in Practice?
Choose the Taigo if you need cargo that is stored deeper or is tall/bulky and prefer a bit more interior volume. Choose the Q3 if you more often load wide or bulky items and a larger opening for easier handling is important.
