What are some major differences between the Audi A7 and A8?

I am trying to decide between the Audi A7 and A8 models but I am not sure which one would be the better fit for me. Can someone highlight some key features that distinguish between the two models?

The Audi A7 is considered to be more of a luxury sports sedan, while the A8 is known as the flagship luxury sedan of the brand. This means that the A7 may have a sportier driving experience, while the A8 focuses more on comfort and luxury.

One major difference between the A7 and A8 is their size. The A8 is a larger vehicle, offering more interior space and a longer wheelbase. The A7, on the other hand, has a sleeker and more compact design.
