Trunk comparison: BMW X5 vs Jeep Renegade

Key Differences
The BMW X5 offers significantly more cargo length: with the seats folded down, the trunk is +13 in (22%) longer, and with the first row upright, +10.6 in (35%) longer compared to the Jeep Renegade.
The X5 is also +5.5 in (15%) wider at the narrowest point of the trunk, and the trunk opening is +4.3 in (11%) wider than the Renegade.
Conversely, the Jeep Renegade has a higher trunk opening (+3.5 in, 11%) and a significantly greater depth from the loading edge to the trunk floor (+5.1 in, 1300%) than the X5. The loading edge height above the road differs only slightly (BMW +1.2 in / 4% higher) and is therefore not a major factor.
Impact on Usability
Because the BMW X5 is longer and wider, it is better suited for long or wide loads (e.g., furniture, long items, skis) and offers more usable space with the seats folded down. The wider opening makes it easier to load bulky items across the opening.
The Jeep Renegade, on the other hand, scores with tall or bulky cargo: the higher opening and significantly greater depth from the loading edge to the trunk floor create more vertical space and make it easier to store tall boxes or upright items.
Additionally, the loading edge on the Renegade is slightly lower, which makes lifting heavy items somewhat easier.
In short: for longer and wider cargo, the BMW X5 is the better choice; for tall, upright, or easier-to-handle cargo, the Jeep Renegade offers advantages.
