Trunk comparison: Opel Grandland vs Tesla Model Y

Main Differences

Clear strengths emerge on both sides in terms of volume and dimensions. The Tesla Model Y offers significantly more loading length: with the seats folded down, the trunk of the Model Y is 9.8 in (about 15%) longer than that of the Opel Grandland, and with the first row upright, the advantage is even 8.7 in (about 25%).

This makes the Tesla superior especially for long items. The Opel Grandland, on the other hand, has a significantly higher trunk opening (+4.7 in / 17%) and a noticeably greater depth between the loading edge and the trunk floor (+6.3 in, stated as 1500%), indicating more usable interior height and depth. Additionally, the loading edge of the Opel is on average 3.1 in (11%) higher above the ground, which affects the loading/unloading height.

Width differences (narrowest point +6%, opening width +7% in favor of the Opel) are under 10% and less notable but can be relevant for very wide items.

What impact do these differences have on usability?

The greater loading length of the Tesla makes it easier to transport longer items (slats, pipes, longer furniture parts)—both with folded rear seats and with the first row upright. For users who frequently transport long, flat, or bulky items, the Model Y is practically advantageous.

The higher trunk opening and greater depth of the Opel mean more usable interior height and volume vertically: tall or stacked items often fit better in the Grandland. The additional depth also allows items to be pushed deeper into the trunk without protruding over the loading edge.

The higher loading edge of the Opel (by 3.1 in) has two practical consequences: on one hand, it increases the physical effort when lifting heavy items onto the loading edge; on the other hand, the lower loading edge of the Tesla reduces lifting and makes sliding heavy loads easier.

Those who frequently load heavy boxes or equipment therefore benefit from the Tesla's lower loading edge.

In brief:

• Important for long items: Tesla Model Y (more loading length).
• Important for tall or vertically stacked cargo: Opel Grandland (higher opening, more depth).
• Important for easy handling of heavy loads: Tesla Model Y (lower loading edge).
• Width differences are minor (<10%) and hardly decisive for most uses.

Conclusion

The choice depends on the typical usage profile: those who regularly transport long, flat, or heavy items have the more practical solution with the Tesla Model Y.

For users who more often need tall or stacked cargo and prefer more vertical volume, the Opel Grandland is better suited—albeit at the cost of a higher loading edge when loading and unloading.
