Trunk comparison: Peugeot 3008 vs VW Golf Wagon (Mk5)

Key Differences
The most noticeable differences concern the interior geometry and the trunk sill height.
The Peugeot 3008 has a significantly larger trunk depth measurement: the depth (trunk sill → trunk floor) is +2.4 in or +120% greater than in the VW Golf 5. Additionally, the trunk sill of the Peugeot is +6.3 in (25%) higher above the road than the Golf.
All other values (length differences with folded/upright rear seats, opening height +1.6 in, width differences +0.4 in) are indicated at 6% or less and thus significantly smaller.
Implications for Usability
Greater trunk depths in the Peugeot mean more usable interior height behind the trunk sill: bulky or tall items can be placed further inside, loose cargo sits lower in the cargo space and is less likely to shift. This is advantageous for transporting crates, plants, or stacked luggage.
The significantly higher trunk sill of the Peugeot makes loading and unloading heavier items more strenuous: lifting effort and overcoming the sill are greater, so loading and unloading, for example, strollers, heavy crates, or furniture is easier with the Golf.
Since the trunk sill increase (+6.3 in) is greater than the additional depth (+2.4 in), the loading floor of the Peugeot generally sits higher above the road than the Golf, which only partially offsets the advantage of the greater depth for handling heavy loads.
The slightly longer loading floors of the Golf (each 2–6% longer depending on seat position) favor it when maximum cargo length is important (long items with folded seats). Small width and opening differences (≈1–5%) are usually negligible in practice.
Conclusion
For frequent transport of tall or bulky but not necessarily heavy cargo, the Peugeot 3008 is better suited due to the deeper loading floor and slightly wider opening. For easier handling of heavy items and when longer cargo length is needed, the VW Golf 5 is the more practical choice.
