Trunk comparison: Opel Astra Wagon vs Tesla Model Y

Key Differences (highlighted: >10%)

Among the measured values, three differences stand out clearly: The height of the trunk opening of the Opel Astra is 6.3 in or 23% larger than that of the Tesla Model Y, the depth of the trunk (loading edge → floor) in the Opel is 5.5 in or 1300% larger, and the loading edge of the Tesla is 3.5 in or 15% higher above the ground than that of the Opel.

Other dimensions (length with folded/upright seats, widths) are below the 10% mark and are therefore less decisive.

Impact on Practical Usability

The combination of a higher opening and significantly greater depth makes the Opel particularly practical for bulky, tall items: due to the higher trunk opening (+23%), bulky parts can be more easily loaded or stood upright.

The deeper loading recess (+1300%) means that luggage and suitcases lie deeper in the cargo space and can therefore be better stacked or concealed — practical for shopping or suitcases that should not extend beyond the loading edge.

Additionally, the lower loading edge in the Opel makes lifting heavy loads easier, because the Model Y has a loading edge 3.5 in higher (+15%), which makes loading more strenuous.

The Tesla Model Y does offer slightly more usable loading length (about ~9% longer with folded seats or first row upright), but this is a minor advantage compared to the differences mentioned above.

For long, flat loads (e.g., skis, long boards), the Model Y is therefore slightly more favorable; for tall, bulky, or heavier loads, the Astra is clearly more advantageous in everyday use.

Width differences at the narrowest point and at the opening are in the single-digit percentage range and hardly affect everyday usability: they are less relevant compared to differences in opening height, depth, and loading edge.
