Trunk comparison: Fiat Panda vs Toyota Corolla Wagon

Key Differences
The Toyota Corolla Touring Sports offers significantly more cargo length: with the seats folded down, the trunk is +29.5 in (68%) longer, and with the first row of seats upright, it is even +18.9 in (89%) longer than the Fiat Panda.
The Fiat Panda, on the other hand, has a higher trunk opening and a deeper cargo floor: the opening is +5.1 in (17%) higher, and the depth from the loading edge to the trunk floor is +3.9 in (125%) greater than in the Corolla Touring Sports.
Implications for Usability
Cargo length (Corolla): The significantly greater length of the Corolla makes it better suited for long items (e.g., slats, skis, longer furniture parts) and for larger amounts of luggage with the seats folded down.
The longer loading surface overall offers more flexible storage space and facilitates transport tasks that require cargo depth over length.
Height and depth (Panda): The higher trunk opening and the significantly greater depth from the loading edge to the trunk floor in the Panda offer advantages for tall or stackable cargo and for items that need more vertical space.
The deeper cargo well also allows volume to be used "downwards," so bulky but not very long items can lie more stably.
Width and loading edge: Width differences are minor (Panda is slightly wider inside at the narrowest point, Corolla has a minimally wider opening) and have little practical impact.
The Panda's loading edge is slightly higher above the road (+2 in / 8%), which makes lifting heavy loads a bit more difficult, but this difference is small and was not highlighted as a main difference.
In short: For transport tasks that require length, the Toyota Corolla Touring Sports is clearly superior. For bulky, tall, or stackable cargo over limited length, the Fiat Panda offers practical advantages due to its higher opening and deeper cargo well.
