Trunk comparison: Jeep Renegade vs VW Tiguan Allspace

Biggest Differences (Summary)
With the seats folded down, the VW Tiguan Allspace offers significantly more cargo space: it has +14.6 in (24%) longer trunk length than the Jeep Renegade.
The Tiguan's advantage is similarly clear when the first row of seats is upright: +13.8 in (45%) longer cargo depth. Conversely, the Jeep Renegade surpasses the Tiguan when all seats are upright: the Renegade offers +11.8 in (64%) more trunk length.
The Jeep's trunk opening is +6.7 in (24%) higher, and the depth from the loading edge to the trunk floor is +5.5 in (1300%) greater in the Renegade.
The Tiguan also has a significantly wider trunk opening: +6.3 in (16%). Smaller differences that hardly matter are the loading edge height (+0.4 in / 1% in favor of Tiguan) and the narrowest width in the trunk (+1.6 in / 4% in favor of Tiguan).
What impact do these differences have in practice?
The VW Tiguan Allspace is the better choice when it comes to transporting long or flat items: its significantly greater loading length with folded seats and upright first row, as well as the wider trunk opening, make it easier to load long furniture parts, roof box-like items, or multiple suitcases.
Those who frequently transport large, flat, or wide loads or regularly fold down seats for cargo purposes benefit from the Tiguan.
The Jeep Renegade scores in everyday use with more usable cargo depth when fully seated: when all seats are upright, there is more trunk space for shopping bags, trolleys, or passengers' luggage.
The higher trunk opening and the greater depth from the loading edge to the floor make the Renegade more practical for bulky, tall items (e.g., crates, plants, larger boxes) and tend to offer more vertical space directly behind the opening.
However, the greater "depth" between the loading edge and floor may mean heavy items need to be lifted over a larger step.
In short: Tiguan Allspace = better for length and width of cargo space (especially with folded seats); Jeep Renegade = more practical with full seating and for taller/bulkier loads due to higher opening and deeper cargo floor. Smaller differences like loading edge height and narrowest width are negligible in practice.
