Trunk comparison: Audi A6 Avant vs Jeep Compass

Key Differences
The Audi A6 Avant offers significantly more cargo space lengthwise: with the seats folded down, the trunk of the A6 Avant is 12.2 in (19%) longer, and with the first row of seats upright, even 13.8 in (43%) longer than the Jeep Compass.
The Jeep Compass, on the other hand, has a higher trunk opening (+4.7 in, 16%), a significantly greater depth between the loading edge and trunk floor (+5.5 in, 700%), and a higher loading edge above the road (+5.1 in, 20%) compared to the A6 Avant.
The width at the narrowest point is only slightly larger in the A6 Avant (+1.2 in, 3%), and the trunk opening width is practically the same (+0.4 in, 1%).
Impact on Usability
For transporting long, flat items (e.g., furniture parts, long boxes, skis), the A6 Avant is the better choice: the significantly greater loading length both with folded seats and with upright seats allows loading longer goods without repositioning or removing seats.
The slightly larger minimum width further supports accommodating bulky items. Additionally, the lower loading edge of the A6 makes lifting heavy loads into the trunk easier.
The Jeep Compass is advantageous when it comes to height and volume in the vertical direction: the higher trunk opening and the greater depth from the loading bar to the floor enable loading taller or bulkier items (e.g., tall boxes, stacked suitcases).
However, the higher loading edge makes loading heavy or bulky items more difficult, as more lifting is required. Overall, the Compass is more practical for tall luggage and off-road-oriented use, while the A6 Avant is better suited for longer, flatter, or heavier loads in everyday use.
