Trunk comparison: Peugeot 5008 vs VW Taigo

Summary of Differences
With the seats folded down, the Peugeot 5008 offers a significantly longer cargo area than the VW Taigo: +12.6 in (21%). When the first row of seats is upright, the Peugeot's advantage is even greater: +9.1 in (28%).
Conversely, the VW Taigo has a significantly larger trunk than the Peugeot with all seats fully upright: +18.9 in (141%).
The depth of the trunk (distance from loading edge → trunk floor) is significantly greater in the Taigo: +7.5 in (indicated as 1900% in the source code).
Additionally, the narrowest width in the trunk is greater in the Peugeot: +6.3 in (16%), and the width of the trunk opening is also larger in the Peugeot: +5.5 in (14%).
Impact on Usability
These differences determine practical everyday usability: For longer or bulky items (e.g., furniture parts, long sports equipment), the Peugeot 5008 has the advantage because it offers more loading length with folded seats and an upright first row.
The greater interior width and wider opening in the Peugeot make it easier to store wide items and to load/unload with more clearance on the sides.
The VW Taigo scores when all seats are in use: with significantly more trunk length at full seating, it is better suited for trips with a full load of passengers who still need luggage space.
The significantly greater depth in the Taigo means the usable cargo space is shaped differently vertically (more space below the loading edge), which on one hand offers more volume but on the other hand can make lifting heavy loads over the loading edge more difficult or affect storing flat cargo.
In summary: Peugeot = more flexible, wider cargo space for long/bulky loads; Taigo = more usable space with full occupancy and a deeper loading area that requires different loading behavior.
