A key advantage of the Model Y, in theory, is the future availability of a third-row seat. While we haven’t sat in it yet, we saw one at the reveal of the Model Y. It looked so cramped that we wouldn’t recommend waiting for it to be available. Most SUVs of this size don’t offer a third row because they lack the space to make it usable. And the placement of a third row tends to minimize cargo space, so it isn’t much of an advantage in the real world.
The process of measuring trunk space in a sedan differs from that of the storage space in a hatchback or SUV, making direct comparisons difficult. That being said, just look at the Model Y’s cargo area and you’ll know that it has more space than the Model 3. In the rear, the Model Y also has two underfloor storage spaces — the Model 3 has just one.
It’s also easier to hide your stuff in the Model 3’s trunk compared to the Model Y. The Y doesn’t even have a cargo cover, though its rear window is at least heavily tinted and angled, making it difficult to see what’s inside.
Because all three vehicles don’t have a traditional gasoline engine, the space under the hood serves as additional storage — call it a frunk. The sole interior storage measurement Tesla provides is “total enclosed cargo volume” at 68 cubic feet for the Y. While this number is larger than the Mach-E’s (59.6 cubic feet behind the first row), Tesla doesn’t say whether its figure includes frunk storage space. Ford lists that spec at 4.8 cubic feet.
