Why does the Audi A8 have a split-trunk design?

I've noticed that the Audi A8's trunk is separated into two sections, with a small lower trunk and a larger upper trunk. Is this design just for aesthetic purposes or does it serve a practical function?

The split-trunk design in the Audi A8 is more than just a stylistic choice. It allows for better weight distribution, which can improve the handling and stability of the car, especially at higher speeds.

Having a split-trunk also allows for easier loading and unloading of items. You can keep smaller items in the lower trunk and larger ones in the upper trunk, making it more organized and accessible.

This design also enables the A8 to have a larger upper trunk, providing more storage space for luggage or other items. It's a practical and functional feature that sets the A8 apart from other luxury sedans.
