Trunk comparison: Audi A3 Sportback vs Toyota Corolla Wagon

Key Differences (over 10%)

The Toyota Corolla Touring Sports offers significantly more cargo length: with the seats folded down, the Corolla's trunk is 25% (≈14.6 in) longer, and with the first row of seats upright, it is even 32% (≈9.8 in) longer than the Audi A3 Sportback.

In contrast, the Audi has a significantly greater trunk depth (measured from the loading edge to the trunk floor): here the Audi leads the Corolla by 100% (≈3.1 in).

Impact on Usability

The greater cargo length of the Corolla makes it more practical for long or flat loads (e.g., furniture parts, long boxes, skis) and for users who frequently need to transport large volumes lengthwise.

More length with folded or upright seats also means more flexible interior layout and more usable cargo volume for vacation luggage or larger shopping trips.

The greater depth in the Audi addresses different use cases: a deeper loading surface (more distance between loading edge and trunk floor) allows for deeper sinking of the load, which offers advantages when stacking or with irregularly shaped items and can make securing the load easier.

However, the Audi's loading edge is slightly higher (+1.2 in), which makes lifting heavy items in a bit more strenuous.

Smaller differences (under 10%) such as a slightly higher trunk opening in the Audi (+0.8 in), a slightly larger narrowest width in the Audi (+1.6 in), or a slightly wider opening in the Corolla (+2.4 in) only marginally affect everyday use: the Corolla's opening helps when loading wider items, while the slightly larger interior width of the Audi can be useful in tight spots.
