What are the key differences between the Audi A7 and A6 sedans?

I am interested in purchasing an Audi sedan, but I am not sure which model is the best fit for me. How does the A7 differ from the A6, and what unique features does it offer?

The main difference between the Audi A7 and A6 is their respective body styles. The A7 is a sleek and sporty 4-door hatchback, while the A6 is a more traditional 4-door sedan. This means the A7 offers a more dynamic and unique driving experience, with added cargo space and versatility.
