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

I am trying to decide between the Audi A7 and A7 Sportback, but I'm having trouble understanding the main distinctions between the two models. Can someone provide a detailed explanation?

The main difference between the Audi A7 and A7 Sportback is the body style. The A7 Sportback features a sloping rear hatchback design while the A7 has a more traditional sedan body. This means that the Sportback offers a larger cargo space and a more unique look, while the A7 has a more classic design and potentially better aerodynamics.

In terms of performance, both the Audi A7 and A7 Sportback offer similar engine options and power, so there's not much difference between the two in terms of driving experience. However, the A7 Sportback can feel slightly more agile and responsive due to its slightly lighter weight and smaller size.
