Trunk comparison: Audi Q2 vs VW T-Cross

Key Size Differences
With the rear seats fully folded down, the models have the same trunk length.
Two differences stand out: The Audi Q2 offers a longer cargo area with the rear seat upright — +4.7 in (18%) more length compared to the VW T-Cross — and the VW T-Cross has a significantly deeper trunk well (distance from loading edge to trunk floor) — +2 in (45%) compared to the Audi.
Other, smaller deviations (not classified as >10%): The trunk opening of the Audi is 2.8 in (10%) higher, the loading edge of the Audi is 2 in (7%) higher above the ground, the narrowest trunk width is 0.4 in (1%) larger in the VW, and the opening width in the VW is 1.6 in (4%) larger.
What Are the Practical Effects of These Differences?
The longer usable loading area of the Audi Q2 with rear seats upright makes it practical when long items need to be transported regularly without folding down the seat bench (e.g., skis, long packages, individual furniture parts). The 18% longer area increases flexibility for bulky, longer cargo in everyday use.
The significantly deeper trunk well of the VW T-Cross means that volume and stacking height in the cargo area can be used more effectively: bulky or tall luggage can be lowered further "into" the trunk.
Combined with the slightly larger opening width, this makes the T-Cross more favorable for voluminous, less long cargo.
The slightly higher trunk opening of the Audi makes it easier to insert tall items through the opening, but the higher loading edge of the Audi (2 in) makes lifting heavy loads more strenuous.
The VW's loading edge is lower, which simplifies loading from the ground, but the deeper well requires more reaching in when loading.
Conclusion: For frequent transport of long items with seats upright, the Audi Q2 is advantageous. For better usable volume, easier stacking, and a slightly wider opening, the VW T-Cross is better suited.
