Why is the Audi A7 considered a 'sportback' vehicle?

I've heard the term 'sportback' used to describe the Audi A7, but I'm not sure what it means. Can someone explain the unique feature of this vehicle that sets it apart from other Audi models?

The Audi A7 is considered a 'sportback' vehicle because of its unique four-door coupe design, which combines elements of a sedan and a hatchback. This allows for both a sleek, sporty look and increased practicality in terms of cargo space.

'Sportback' is a term coined by Audi to describe the design of the A7, which is essentially a fastback version of a sedan. The sloping rear of the car not only adds to its sporty appearance, but also improves aerodynamics and performance.
