Trunk comparison: BMW i4 vs VW Caddy Wagon

Key Differences

There are clear contrasts in the volume and shape of the cargo space: The BMW i4 offers significantly more loading area when the seats are folded down — it has a trunk that is 23.6 in (52%) longer than the VW Caddy Wagon, allowing for longer items.

The VW Caddy, on the other hand, scores points for the height and width of the opening: the trunk opening is 18.5 in (70%) higher than the i4, the narrowest interior width is 9.8 in (28%) larger, and the opening width is 7.5 in (20%) larger.

The BMW also has a greater ratio depth between the loading edge and the trunk floor — the depth is 3.1 in (400%) greater — and a higher loading edge above the road — by 5.1 in (23%).

When the first row of seats remains upright, the VW Caddy Wagon has a slightly longer trunk (+3.5 in / 9%), but this difference is under 10% and therefore less significant.

Impact on Usability

The differences lead to different strengths: For long, flat, or poorly stackable items (e.g., long slats, skis, panels), the BMW i4 with folded seats is often the better choice thanks to the significantly greater loading length.

However, the low opening height and narrower interior width of the i4 considerably limit loading tall or wide parts — a long board may fit, but a tall box or bulky furniture pieces will not. The higher loading edge of the i4 also makes lifting heavy loads more strenuous.

The VW Caddy Wagon is more practical for bulky, tall, or wide-format cargo: the significantly higher opening and larger widths allow easy loading of crates, furniture parts, or bulky items. The lower loading edge facilitates manual loading and unloading of heavy items and makes handling more ergonomic.

With normal use and the first row of seats upright, both vehicles offer comparable everyday practicality, with the Caddy clearly having the advantage in volume and loading comfort for large, unwieldy loads.
