What is the difference between the Audi A7 and A7 Sportback models?

I am considering purchasing an Audi A7, but I am confused about the difference between the standard A7 and the A7 Sportback. Can someone explain the technical differences between these models?

The main difference between the Audi A7 and A7 Sportback models is their body style. The A7 is a traditional sedan, while the A7 Sportback has a more coupe-like design with a sloping hatchback rear end. This gives the A7 Sportback a more sporty and aerodynamic look.

In addition to the body style, the A7 Sportback also offers more cargo space compared to the A7 sedan. The Sportback has a maximum cargo capacity of 24.9 cubic feet, while the A7 sedan only has 18.9 cubic feet.
