Trunk comparison: Audi A6 Sedan vs Peugeot 5008

Key Differences
Significant differences are mainly found in the usable length and the cargo space profile: The Audi A6 offers a trunk that is 31.9 in (238%) longer with upright seats than the Peugeot 5008. The depth of the trunk (loading edge to trunk floor) is 4.3 in (1100%) greater in the Audi, indicating a significantly deeper cargo area.
The Peugeot has a trunk opening that is 11.8 in (60%) higher than the Audi; additionally, the width at the narrowest point is 5.1 in (13%) larger and the width of the trunk opening is 7.5 in (20%) larger than in the Audi.
Impact on Usability
The significantly longer loading surface of the Audi A6 with upright seating makes it better suited for long luggage or skis without folding down the rear seats.
The greater depth difference (loading edge → floor) in the Audi creates more "trunk volume downward" and increases the capacity with the same opening area; however, this means heavy items must be lowered further down.
At the same time, the loading edge of the Peugeot sits slightly higher (+1.2 in), so loading and unloading heavy loads is generally easier in the Audi due to the lower loading edge.
The Peugeot 5008 scores with a significantly higher opening and overall larger cross-sectional dimensions: the higher trunk opening and greater width (both at the narrowest point and at the opening) make it easier to load bulky, wide, or tall items (e.g., strollers, large boxes, or furniture parts), making everyday storage simpler.
For families or users who often transport wide or tall cargo, the Peugeot is more practical.
Conclusion: For long items and as much usable storage space as possible with upright seating, the Audi A6 is clearly advantageous. For wider or taller cargo and easier handling of large/bulky parts, the Peugeot 5008 is better suited.
