Trunk comparison: Opel Astra Wagon vs Tesla Model Y

Key Differences (>10%)

The measurements reveal several notable differences: The Tesla Model Y offers a significantly longer cargo area with the seats folded down (+11 in / +17%), while the Opel Astra Wagon has advantages in several areas: a higher trunk opening (+3.5 in / +13%), greater depth between the loading edge and trunk floor (+0.8 in / +100%), and a wider narrowest interior width (+5.5 in / +15%).

Additionally, the loading edge of the Tesla sits noticeably higher above the road (+4.3 in / +19%).

Impact on Usability

The longer cargo area of the Tesla with folded seats makes it better suited for long items like slats, furniture parts, or long boards — when length is the main factor, the Model Y wins.

However, the Tesla's loading edge is significantly higher, which makes lifting heavy or bulky loads into the trunk more difficult; the higher loading height increases the effort required when loading.

The Opel scores in everyday practicality: the higher trunk opening provides more vertical clearance when loading tall items, and the greater depth between the loading edge and floor as well as the wider narrowest point ensure that bulky or wide loads fit more easily and can be stored more conveniently.

Together with the lower loading edge, this results in overall easier handling when loading — especially with heavy or bulky goods.

Conclusion: For longer, flat loads, the Tesla Model Y is the better choice; for easier, more ergonomic loading and more usable width/height in everyday use, the Opel Astra Wagon is more advantageous.
