What are the main differences between the Audi A7 and the A8?

I am trying to decide between the Audi A7 and the A8, but I'm having trouble understanding the main distinctions between the two models. Can someone provide some insight?

The main difference between the Audi A7 and A8 is their size and price point. The A7 is a mid-size luxury sedan with a sleek design, while the A8 is a full-size luxury sedan with a more traditional appearance. The A8 also typically has a higher price tag due to its larger size and more premium features.
