Trunk comparison: BMW i4 vs Peugeot 5008
Key Differences
The measurable differences show two clear strengths: The BMW i4 has a significantly longer trunk with seats upright (+25.2 in / +188%), and the depth from the loading edge to the trunk floor is also much greater in the BMW (+3.5 in / +900%).
The Peugeot 5008 has clear advantages in the trunk opening and narrowest width: the opening is higher (+5.1 in / +19%) and wider (+7.5 in / +20%), and the smallest interior width is significantly greater than that of the BMW (+10.6 in / +31%).
Smaller differences: Peugeot offers slightly more volume with folded seats (+4.7 in / 7%) and with the first row upright (+2.8 in / 7%), and the loading edge height above the road is practically the same (+0.4 in / 1% in favor of the BMW).
Impact on Usability
BMW i4 – Advantages in length and depth: The strong increase in length with all seats upright makes the BMW better suited for long, flat cargo without folding the seats (e.g., skis, long boards, longer boxes).
The greater depth between the loading edge and trunk floor (deeper floor) creates a recessed loading area that holds long or deeply lying items more stably and offers slightly more usable vertical clearance below the loading edge.
However, the narrow opening and smaller interior width limit loading very wide or irregularly shaped items.
Peugeot 5008 – Advantages in width and opening: The higher and especially wider trunk opening, along with the significantly larger narrowest interior width, make the Peugeot much more practical for bulky, wide, or awkward cargo (strollers, wide furniture parts, large boxes).
The slightly greater overall length with folded seats further supports cargo volume in the combined loading state. For frequent loading of large, bulky items, the Peugeot is the more practical choice.
Conclusion – Typical Use Scenarios
- Those who often transport long items without folding seats benefit from the BMW i4 (more length and recessed loading area).
- Those who more frequently load wide, tall, or bulky loads or place high value on easy loading are better served by the Peugeot 5008 (larger opening and significantly more width).
- Smaller volume differences when folding seats exist (favoring Peugeot) but influence usability less strongly than the differences highlighted above.
