Trunk comparison: Opel Corsa vs Peugeot 5008

Key Differences
In terms of storage space, the Peugeot 5008 is clearly superior when it comes to folded down or extended cargo areas: the 5008 offers 22 in (42%) more length when all seats are folded down, and 15.4 in (59%) more length when the first row of seats is upright.
It is also advantageous in width: the narrowest point of the trunk is 7.5 in (20%) wider and the opening width is 10.6 in (31%) greater than in the Corsa.
On the other hand, the Opel Corsa has a larger trunk when all seats remain upright: 12.6 in (94%) more cargo length than the 5008. Additionally, the Corsa has a significantly greater depth between the loading edge and the trunk floor (+6.7 in / 1700%).
Impact on Usability
For transporting long items or with folded seats, the Peugeot 5008 is more practical: the extra length and larger opening make it easier to load furniture, sports equipment, or long packages. The wider dimensions reduce issues with bulky or wide cargo.
The Opel Corsa has the advantage in everyday use with full seating: its greater cargo length with upright seats makes it more suitable for daily shopping or luggage when all passengers are on board.
The greater depth in the Corsa means more storage space in a deep trunk floor, but it can make loading heavy, flat items more difficult because they may slip under the loading edge; the loading edge height itself differs little.
In short: Peugeot 5008 = better for long and wide or bulky loads; Opel Corsa = more compact everyday trunk with full seating and a deeper loading well.
