Trunk comparison: Jeep Renegade vs Peugeot 5008

Key Differences
The Peugeot 5008 offers 13.8 in (23%) more trunk length with the seats folded down and 11 in (36%) more trunk length with the first row of seats upright than the Jeep Renegade.
Conversely, the Jeep Renegade has 16.9 in (126%) more trunk space with all seats fully upright than the 5008. Furthermore, the height of the Jeep's trunk opening is 3.5 in (11%) larger, and the depth of the trunk (distance from loading edge to floor) is 5.1 in (1300%) greater in the Jeep.
Although the Jeep's loading edge is 2.8 in (10%) higher off the ground (not >10%), the narrowest width is 7.5 in (20%) wider in the Peugeot, and the width of the trunk opening is 5.9 in (15%) larger in the Peugeot.
Impact on Usability
The greater length dimensions of the Peugeot (with folded seats +13.8 in and with the first row upright +11 in) clearly make it superior for long items such as slats, skis, furniture parts, or transport boxes, especially when folding down the rear seat.
The greater width at the narrowest point (+7.5 in) and the larger opening width (+5.9 in) make loading wider items easier and increase the practical usable space for bulky luggage.
The Jeep scores points when all seats are in use: with 16.9 in more trunk space when fully seated, it is better suited for trips with multiple passengers who still want to carry significant luggage.
The higher trunk opening (+3.5 in) allows for loading taller items, and the significantly greater interior depth (+5.1 in) provides more vertical or rear space — useful for higher stacks or bulky, voluminous cargo. The slightly higher loading edge (+2.8 in / 10%) makes lifting heavy loads minimally more strenuous.
In short: Peugeot 5008 = better for long and wide cargo as well as generous opening when loading; Jeep Renegade = more practical when all seats are used, and better for taller/voluminous cargo thanks to deeper interior and higher opening.
Which choice makes more sense depends on typical use: regular transport of long/wide items (Peugeot) vs. daily use with many passengers plus storage for bulky items (Jeep).
