Trunk comparison: Ford Focus vs Tesla Model Y

Key Differences
The Tesla Model Y offers significantly more cargo length: with the seats folded down, the trunk of the Model Y is 15.4 in (25%) longer than that of the Ford Focus, and with the first row of seats upright, it is even 13.4 in (44%) longer.
In contrast, the Ford Focus has a higher trunk opening: the opening is 4.3 in (16%) higher than that of the Model Y.
Additionally, the depth of the trunk (measurement: loading edge → trunk floor) differs greatly: the Ford Focus is 7.1 in (1700%) higher here than the Model Y.
All other measured values (loading edge height above the road, width at the narrowest point, width of the trunk opening) differ by only about 1–6% and are therefore less relevant.
Impact on Usability
More cargo length in the Tesla Model Y means: longer items (e.g., slats, skis, longer furniture parts) can be transported much more easily, especially when the rear seats are folded down. Those who often transport long, flat, or bulky items thus benefit from the Model Y.
The higher trunk opening of the Ford Focus makes loading tall or bulky items easier in the upright position (e.g., tall boxes, plants, upright suitcases).
Combined with the significantly greater depth (larger vertical difference between loading edge and trunk floor), the Focus offers more usable height in the cargo area below the opening, thus more vertical volume in the rear section.
The greater depth in the Focus has two effects: it creates more storage space in the trunk recess (practical for stackable or tall cargo), but makes lifting heavy items over the loading edge somewhat more strenuous because a greater height difference must be overcome.
The Model Y, with its flatter loading floor, makes sliding and removing heavy or bulky parts easier but offers less vertical space.
In summary: For transport lengths and flat-lying, long items, the Tesla Model Y is more advantageous; for upright, tall items and more usable depth in the cargo area, the Ford Focus is better suited.
