What is the maximum capacity of the Audi A8's fuel tank?

I am trying to plan a road trip and want to know how often I will need to make stops for gas. What is the fuel tank capacity of the Audi A8?

The fuel tank capacity for the Audi A8 can vary depending on the model and engine type. On average, it is around 19 gallons, but it can be as high as 24 gallons for some trims.

If you want to be sure about the exact capacity for your specific Audi A8, check the owner's manual or the fuel tank label located inside the fuel door. It should have the capacity listed in either liters or gallons.
