What is the maximum cargo space in the Audi A6?

I often need to transport large items for work and am looking to purchase an Audi A6. Can someone tell me the exact maximum cargo space in this vehicle?

The Audi A6 has a maximum cargo space of 35 cubic feet with the rear seats folded down. This should be plenty of space for your transportation needs.

The maximum cargo space in the Audi A6 is 28 cubic feet with the rear seats in their upright position. However, you can easily fold down the seats to increase the space.
