Trunk comparison: Audi A6 Avant vs VW Tiguan Allspace

Key Differences

The Audi A6 Avant offers significantly more loading length with a certain seat layout: +27.6 in (149%) when all seats are upright.

The depth of the trunk (loading edge to trunk floor) is nominally +0.8 in (100%) greater in the A6. The loading edge of the VW Tiguan Allspace, however, sits +5.1 in (20%) higher above the road than in the A6. All other measured differences are below or around 10% (e.g., +2.4 in / 3% with folded seats, +2 in / 4% with upright first row, +0.4 in / 1% opening height).

The width at the narrowest point is the same; the width of the trunk opening is 3.9 in (10%) larger in the Tiguan, exactly at the threshold for highlighting.

Implications for Usability

The significantly longer cargo area of the A6 with upright seating makes it better suited for long items, even when the seats are in use (e.g., slatted frames, long boxes, or sports equipment).

The nominal extra depth of +0.8 in slightly increases usable loading height — due to the small absolute value (0.8 in), the practical effect is moderate: a slight advantage when stacking flatter items.

The higher loading edge of the Tiguan (+5.1 in) makes lifting heavy or bulky loads more difficult compared to the A6; conversely, loading and unloading in the A6 is physically more comfortable.

The 3.9 in wider trunk opening of the Tiguan facilitates inserting very wide items through the opening, but the same interior width at the narrowest point limits space for truly wide cargo inside — wider items fit more easily through the opening, not necessarily better inside the vehicle.

In summary: For long, less bulky cargo with occupied seats and for more ergonomic lifting, the Audi A6 Avant is advantageous. For bringing in very wide parts, the Tiguan offers a practical, though limited, advantage thanks to the wider opening. Smaller differences under 10% are usually negligible in everyday use.
