What are the main differences between the Audi A7 and A7 Sportback models?

I'm considering purchasing an Audi A7, but I'm not sure what the major differences are between the A7 and A7 Sportback models. Can someone provide a technical breakdown for me?

The main difference is in the body style. The A7 has a traditional sedan design, while the A7 Sportback has a more coupe-like design with a sloping rear roofline. Additionally, the A7 Sportback offers more cargo space due to its hatchback design.

In terms of performance, the A7 Sportback has a slightly lower curb weight and improved aerodynamics, resulting in better handling and fuel efficiency. However, the A7 offers a more powerful engine option.

Aesthetically, the A7 Sportback has a more sleek and modern appearance, while the A7 has a more traditional and understated design. It ultimately depends on your personal preference.
