Trunk comparison: Audi A4 Avant vs Opel Astra Wagon

Summary of the main differences

The clearest difference lies in the depth of the trunk: The Opel Astra Sports Tourer has a trunk floor that is 3.5 in deeper (+180%) compared to the Audi A4 Avant. The height of the trunk opening is the same on both models.

Other deviations are small: the Audi offers a loading length that is 2 in longer with the seats folded down and 1.2 in more length with the rear seats upright, the Audi's loading edge is 0.8 in higher above the road, the narrowest trunk width is 1.2 in larger on the Opel, and the width of the trunk opening is 2 in larger on the Opel.

What usage differences result from this?

Because the trunk floor of the Opel is significantly deeper and at the same time the loading edge of the Audi is slightly higher, the Audi trunk floor sits about 4.3 in higher above the road in practice than the Opel.

This makes a noticeable difference when loading and unloading heavy items: The Opel is more favorable for frequent lifting and stowing of bulky or heavy loads due to the lower floor and wider opening, as the lifting angle and physical effort are reduced.

The Audi, on the other hand, scores with a slightly greater loading length (especially with folded seats), which can pay off for very long items like skis or laminate boards.

The slightly higher loading edge of the Audi (≈0.8 in) makes lifting heavy loads more difficult but hardly makes a difference with light luggage or stacked goods.

In summary: Those who frequently load wide, bulky, or heavy items benefit more from the Opel Astra Sports Tourer (deeper floor, wider opening). Those who occasionally need to transport very long items have a slight advantage with the Audi A4 Avant due to the greater loading length.
