Trunk comparison: Toyota Corolla Wagon vs Durchschnitt Subcompact

Key Differences
The Toyota Corolla Touring Sports offers significantly more cargo length: +22.8 in (45%) with the seats folded down and +15.4 in (62%) with the first row upright compared to the average subcompact.
Other notable differences favoring the average include the greater depth of the trunk (loading edge to trunk floor) with +4.3 in (138%) and the higher loading edge of the average with +3.5 in (14%).
Favoring the Corolla is the width of the trunk opening, which is +4.7 in (13%) larger than the average. Smaller deviations (under 10%) are the slightly higher opening height of the average (+2.4 in, 8%) and the slightly greater width at the narrowest point for the average (+1.2 in, 3%).
Impact on Usability
More length in the Corolla specifically means: longer items (e.g., skis, slats, furniture parts) can be accommodated more easily, and overall cargo capacity for lengthwise-oriented loads is significantly higher.
The wider trunk opening in the Corolla makes it easier to load bulky or wide items, even if the narrowest interior width is slightly smaller.
The greater depth in the average (loading edge → floor) can provide volume advantages but often requires cargo to be maneuvered further down.
Combined with the higher loading edge of the average (+3.5 in), this results in more effort when lifting heavy items in. The Corolla benefits here from a lower loading edge: loading heavy loads is easier and better for the back.
The slightly lower opening height in the Corolla (−2.4 in, not highlighted) is uncritical in most everyday situations but can be relevant for very tall items.
Conclusion: For users who often transport long or bulky items or frequently load heavy cargo, the Toyota Corolla Touring Sports is more practical due to the significantly greater cargo length, wider opening, and lower loading edge.
The average subcompact offers a deeper trunk floor, which can provide volume advantages but makes handling more difficult due to the higher loading edge and narrower opening.
