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

I am confused between the Audi A7 and A7 Sportback models. Can you please explain the technical differences between them and which one is better?

The main difference between the Audi A7 and A7 Sportback is in their body style. The A7 has a traditional sedan shape while the A7 Sportback has a sloping roofline, giving it a more sporty and coupe-like appearance.

Another important difference is in the size and interior space. The A7 Sportback has a longer wheelbase and more interior room compared to the A7, making it more comfortable for passengers and ideal for long journeys.

In terms of performance, the A7 and A7 Sportback have similar engine options. However, the A7 Sportback has a slightly lower center of gravity and a more aerodynamic design, making it slightly more agile on the road.
