Trunk comparison: Opel Astra Wagon vs VW Passat Wagon

Key Differences
The VW Passat Variant offers more cargo length: with the seats folded down, its trunk is 9.1 in (13%) longer, and with the first row of seats upright, it is 4.3 in (11%) longer than the Opel Astra Sports Tourer.
Conversely, the Astra has a significantly deeper interior space between the loading edge and the trunk floor: this value is 2 in (56%) higher in the Opel than in the Passat.
Impact on Usability
Passat – more cargo length: - The longer loading area makes it easier to transport long items (e.g., slats, skis, long furniture parts) and usually without folding complicated intermediate walls.
Even with the rear seat upright, the Passat noticeably gains usable length, making everyday use and larger transports more flexible.
Astra – greater interior height/depth: - The significantly greater depth between the loading edge and the trunk floor means more usable vertical space in the cargo area.
This is advantageous for bulky, tall loads or when items need to stand flatter but higher. Together with the lower loading edge (smaller difference), this results in more ergonomic handling when lifting heavy loads.
In short: If long or elongated cargo is frequently transported, the Passat is more practical. If more vertical storage space and easier loading and unloading are more important, the Astra has many advantages.
