BMW i4 Luggage Test: How big is the trunk?

On paper, the BMW i4 has 10 cubic-feet of space, which is on par with what you'd usually find in a coupe. Now, BMW would tell you that the i4 is a coupe — it is, after all, based on the 4 Series Gran Coupe. But that has four doors, so ... yeah, I'm tired of this argument. Whatever, BMW. Everything is coupe.

What the i4 also is, whether a marketing department wants to acknowledge it or not, is a hatchback. This is good news for a small trunk since it makes the available space more accessible and versatile. That's certainly the case with the 4 Series Gran Coupe. Its 12 cubic-foot trunk is certainly more accessible and versatile than the 3 Series sedan trunk.

Above left is the i4. Above right is the 4 GC.

There's different lighting and a slightly different angle, but these sure look identical to me. Maybe the floor is a smidge higher in the i4? That's my best guess.

For the record, Zac Palmer took the 4 GC pic in Michigan (just in case the snow wasn't a giveaway) and I haven't Luggage Tested one.

There is some under-floor storage, which could be useful for storing a decent-sized something ... if most of it wasn't stuffed with a huge subwoofer. This i4 had a terrific stereo, though, so it could be worth the loss of luggage space.

There's also space on either side, including a deep bin on the right and an area big enough to stow the charge cord.

Alright, let's get to the bags. As with every luggage test, I use two midsize roller suitcases that would need to be checked in at the airport (26 inches long, 16 wide, 11 deep), two roll-aboard suitcases that just barely fit in the overhead (24L x 15W x 10D), and one smaller roll-aboard that fits easily (23L x 15W x 10D). I also include my wife's fancy overnight bag just to spruce things up a bit (21L x 12W x 12D).
