Trunk comparison: BMW 5 Series Touring vs VW ID.4

Summary

The BMW 5 Series Touring offers more usable cargo length: with the seats folded down, the trunk is 8.3 in (12%) longer, and with the first row of seats upright, even 5.9 in (16%) longer than the Volkswagen ID.4. The VW ID.4, on the other hand, scores in the vertical dimension: the trunk opening is 3.9 in (14%) higher, the depth between the loading edge and the trunk floor is 3.9 in (900%) greater, and the loading edge is 3.1 in (12%) higher above the road than on the BMW.

Differences in width are minor (BMW at the narrowest point +2.4 in / 6%, VW opening width +0.4 in / 1%).

Impact on Usability

Practically, this means: For long items (e.g., long boxes, slats, skis), the BMW has the advantage because it offers significantly more length — especially when the rear seats are folded down. The greater length makes loading longer goods easier and more flexible.

The VW ID.4 is better suited for tall or bulky cargo: the higher opening and significantly greater depth create more vertical space, so tall items fit more easily into the interior.

However, the higher loading edge makes lifting heavy items into the vehicle more difficult; loading and unloading heavy loads is more strenuous in the ID.4 due to the higher loading height compared to the lower BMW.

The width differences are small and have little impact on everyday practicality: very wide items benefit slightly from the BMW, but the minimally larger opening width of the VW is negligible.

Conclusion: Those who mainly transport long, flat goods will find the BMW 5 Series Touring the more practical solution.

Those who more often transport tall or bulky cargo and need to lift less weight (or use aids) benefit from the higher, deeper cargo space of the VW ID.4 — but must consider the higher lifting at the loading edge.
