What are the differences between the Audi A7 and A8?

I am trying to decide between the A7 and A8 models of Audi. Both seem to be popular and high-performing options, but what are the specific technical differences between the two?

The Audi A7 is a sportier option with a sleeker design and lower starting price. On the other hand, the A8 provides more luxury and features with its larger size and higher starting price.

The A7 offers a more dynamic driving experience with its lower weight and agile handling, while the A8 provides a smoother and more comfortable ride with its larger size and additional features for enhanced comfort.

Both the A7 and A8 have similar high-quality interiors and advanced technology features, but the A8 has a longer wheelbase and slightly more passenger and cargo space for added convenience and comfort.
