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

I am looking to purchase a new Audi A7, but I noticed that there is also an Audi A7 Sportback model. Can someone explain the differences between the two?

The Audi A7 and A7 Sportback are essentially the same car, with slight differences in body style. The A7 Sportback has a sloping rear roofline for a more aggressive look, while the regular A7 has a more traditional sedan shape.

One key difference between the two is that the A7 Sportback has a hatchback rear trunk, providing more storage space. The regular A7 has a traditional trunk opening.

Another difference is that the A7 Sportback has a more powerful engine option, with a 335 horsepower V6 compared to the regular A7's 248 horsepower engine. The A7 Sportback also comes with standard all-wheel drive.
