Trunk comparison: BMW X2 vs VW Caddy Wagon

Key Differences
With the seats folded down, the BMW X2 offers a cargo area that is +19.7 in (43%) longer than the Volkswagen Caddy Wagon.
With the front seats upright, the VW Caddy Wagon has a cargo depth that is +5.5 in (15%) longer than the X2. The trunk opening of the Caddy is significantly larger: it is +18.9 in (73%) taller and +5.5 in (14%) wider; at the narrowest point, the Caddy is also +5.1 in (13%) wider than the X2. The BMW X2 has a greater depth from the loading edge to the trunk floor (+2.8 in / 350%) and the loading edge of the X2 sits higher above the road (+9.1 in / 40%).
Impact on Usability
The longer cargo area of the BMW X2 with folded seats makes it better suited for long, flat loads (e.g., furniture panels, skis, or long boxes). However, because the X2’s loading edge is significantly higher, loading and unloading heavy items requires more effort or aids (ramp/lift).
The greater depth from the loading edge to the floor in the X2 creates more usable volume for stackable cargo but, combined with the higher loading edge, can make lifting larger loads less practical.
The VW Caddy Wagon scores with bulky and tall items: the significantly larger opening height and width as well as the greater minimum interior width make it easier to load through and stand tall or wide goods upright (e.g., cabinets, boxes, bicycles without disassembly).
Additionally, the Caddy with upright front seats is more practical for mixed passenger and cargo use, as it retains more cargo space than the X2 in this configuration.
In short: BMW X2 = better for long, flat, and stackable cargo with folded seats; VW Caddy Wagon = better for frequent loading/unloading, bulky/tall or wide goods, and for mixing passengers plus cargo.
