Trunk comparison: Opel Astra Wagon vs Tesla Model 3

Key Differences

The most significant differences concern the vertical dimensions of the cargo area: The height of the trunk opening of the Opel Astra Sports Tourer is 13 in (63%) larger than that of the Tesla Model 3. The trunk depth (measured from loading edge to trunk floor) is also 1.2 in (27%) greater in the Opel.

Smaller differences: The Tesla Model 3 offers a slightly longer loading length (+3.5 in / 5% with seats folded down, +2 in / 5% with the front row upright).

The loading edge of the Tesla is 2.4 in (10%) higher above the ground. The narrowest width of the trunk and the width of the trunk opening are each about +2.8 in (7%) larger in the Opel.

Impact on Usability

Opel (higher opening and greater depth): The significantly higher opening and larger interior height make it easier to load tall items upright (e.g., crates, boxes, small furniture).

The additional depth increases usable interior height and prevents tall cargo from hitting the tailgate — less tilting/repositioning needed when loading.

Tesla (somewhat longer loading area): The slightly greater loading length in the Tesla is advantageous for long, flat items (e.g., slats, skis, long panels), especially when the rear seats are folded down.

The higher loading edge on the Tesla (2.4 in) makes lifting heavy items somewhat more strenuous compared to the Opel.

Width and opening: The slightly greater clear width in the Opel (each +2.8 in) helps when loading wider items, although the difference is moderate. For very wide or bulky parts, this can be decisive; for normal luggage, the effect remains minor.

Summary: If you often need to transport tall or bulky cargo upright and comfortably, the Opel Astra Sports Tourer is more practical due to the significantly larger opening and depth. If you more frequently transport long, flat items and value maximum loading length, the Tesla Model 3 offers slight advantages.
