Trunk comparison: Kia Sportage vs Tesla Model Y

Key Differences

In terms of cargo space length, the Tesla Model Y wins: with the seats folded down, the trunk of the Model Y is 9.8 in (15%) longer than that of the Kia Sportage, and with the first row of seats upright, it is 8.3 in (23%) longer.

The trunk depth (loading edge to floor) is the same in both models. The Kia Sportage has a slightly higher trunk opening (+1.6 in / 6%), a larger narrowest interior width (+3.5 in / 9%), and a slightly wider opening (+1.6 in / 4%); the loading edge in the Sportage is +0.8 in (3%) higher above the ground.

Impact on Usability

The longer cargo areas of the Model Y mainly offer advantages in practice when transporting long items: furniture pieces (e.g., shelves, slatted frames), long skis, or bicycles can be placed flatter and more easily, especially when the rear seats are folded down.

The +15% / +23% increase in length enhances flexibility for transport tasks and reduces the need to place items at an angle or let parts protrude from the trunk.

The Kia Sportage, on the other hand, tends to have an advantage with wide and tall loads: the slightly larger minimum interior width and the somewhat higher opening make loading bulky, voluminous items (e.g., wide boxes or kitchen appliances) easier.

The higher loading edge makes lifting in somewhat more strenuous but can improve ground clearance when loading/unloading on uneven terrain. Since these differences are under 10%, their practical impact is moderate.

Conclusion: For users who frequently transport long items or need maximum loading length, the Tesla Model Y is the more practical choice. Those who often load wide, voluminous cargo or bulky items and value somewhat more height/opening space benefit more from the Kia Sportage.
