Trunk comparison: Seat Leon vs Tesla Model 3

Key Differences
The Tesla Model 3 offers significantly more length: with the seats folded down, the trunk is 15 in (26%) longer, and with the front seats upright, it is 9.4 in (29%) longer than the SEAT Leon.
At the narrowest point in the cargo area, the Tesla also has the advantage: the width at the narrowest point is 5.5 in (17%) greater.
In contrast, the SEAT Leon has a significantly taller trunk opening: the opening height is 11 in (54%) greater than the Tesla.
Additionally, the depth between the loading edge and the trunk floor in the Leon is 5.5 in (127%) greater, and the loading edge in the Leon is 3.1 in (12%) higher above the road surface.
The slightly larger width of the trunk opening in the Leon (+3.5 in / 9%) is below the highlight threshold and is not emphasized here.
What Impact Does This Have on Usability?
Long items and flat, long objects: Due to the significantly greater length of the Tesla (both with folded seats and with upright seat rows), long items such as furniture parts, long boxes, or skis can be transported more easily.
Combined with the greater narrow width, the Model 3 is better suited for wide, bulky cargo that needs to fit deep in the cargo area.
Tall or bulky items through the opening: The significantly taller opening height of the SEAT Leon makes loading and unloading very tall items easier — standing boxes, plants, or bulky luggage are more likely to fit through the opening without needing to be tilted sideways.
Vertical volume and stackability: The greater depth between the loading edge and trunk floor in the Leon increases usable volume downward and allows better stacking or storing of items at the trunk floor level. This can be advantageous for bulky shopping or luggage.
Loading and unloading / physical strain: The higher loading edge of the SEAT Leon (+3.1 in) means more lifting effort when placing heavy items inside. The Tesla Model 3, with its lower loading edge, is more practical and ergonomic when sliding or pushing bulky loads in.
Everyday conclusion: For transport tasks involving long or wide items, the Tesla Model 3 is more practical.
For very tall cargo and more vertical space, the SEAT Leon is preferable, although its higher loading edge makes handling heavy loads more difficult. Which option fits better depends on the typical loading profile: long/bulky vs. tall/voluminous items.
